Medicube ZERO PORE ONE DAY PEPTIDE SERUM 30ml

Values: 100% Genuine* · Fragrance-Free (no Fragrance/Parfum entry found in the declared INCI) · Pregnancy-Caution (not contraindicated, but this is an active-strength product — see Safety Notice) · Halal-Friendly* · Vegan-Friendly*

*Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram or animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars. Vegan claim is on the same self-assessed basis — no animal-derived ingredients detected; this is NOT a formal vegan certification.

This is the "graduated" version for someone who's already comfortable with the plain One-Day Serum and wants an added firming angle, not a first acid serum.

Pros: confirmed peptide actives (Oligopeptide-1, an EGF-analog signaling peptide, plus Oligopeptide-2/3 and Acetyl Octapeptide-3), a fourth acid (LHA) for broader exfoliation coverage, fragrance-free, shares the base Serum's 2% Niacinamide. Caveats: two marketed peptide names (Copper Tripeptide-1/GHK-Cu, Acetyl Hexapeptide-1) were not confirmed by exact INCI name in this research pass, exact acid percentages for this specific SKU weren't independently re-verified (assumed shared with the base Serum), and reviewers describe the texture as noticeably stickier than the plain Serum.

Classification: RED. A quadruple-acid complex at an advanced strength (building on the base Serum's 15.2%, plus LHA) is a clinical-grade exfoliating formula, not appropriate for skin under roughly 16 that hasn't developed the sebaceous activity and congestion patterns this product targets.

A gentler starting point: Zero Foam Cleanser 120g (no acids) with PDRN Pink Cica Soothing Toner 250ml — both verified in stock.

Step 1 — When: PM only, on fully cleansed, dry skin.

Step 2 — How much: 2-3 drops for the full face.

Step 3 — How: Press or pat into skin (do not rub), wait 1-3 minutes given the higher active/peptide density, then moisturizer.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

This is a PM-only product — its quadruple-acid content increases sun sensitivity, and Mauritius's UV index runs high nearly year-round.

A typical AM sequence without this serum: 1) Rinse cleanse, 2) Hydrating toner (optional), 3) Niacinamide/soothing serum (optional), 4) Moisturizer, 5) SPF50+ PA++++, mandatory after any acid night, reapplied every 2 hours outdoors.

1) Oil cleanse if wearing sunscreen/makeup, 2) Water cleanser, 3) Optional hydrating toner, 4) Zero Pore One-Day Peptide Serum — 2-3 drops, pressed in, wait 1-3 minutes, 5) Moisturizer, 6) Optional occlusive seal on AC-heavy or very dry nights.

Skin cycling integration: occupies the Exfoliation lane. On a 4-night cycle: Night 1 this serum, Night 2 retinoid (if used), Nights 3-4 recovery.

Technique: pat/press, do not rub — friction increases irritation on an already acid-active, peptide-dense serum. Required skin state: fully dry skin. Wait time: 1-3 minutes before moisturizer — a longer window than the plain Serum, since reviewers report this variant sits stickier and needs more time to settle before the next layer.

Hands deliver 100% of product. Cotton pads absorb approximately 30-40%. Use hands, not a pad.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Global rules: viscosity ladder thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serum layers 30-60s, before sunscreen 10-15 min if going outdoors. Amount defaults: toner/essence 5-8 drops, serum/ampoule 2-3 drops or 1 pump, eye product ½ rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, occlusive seal rice-grain to pea-size, sunscreen 2-finger rule for face plus 1 finger for neck. Hydrators go on slightly damp skin; exfoliating acids go on dry skin, one lane only. If the routine pills, stings, or feels heavy — reduce layers, don't add more.

AM Maximum Stack: 1) Rinse/gentle cleanse (optional), 2) pH-prep toner (optional), 3) Hydrating toner layers 1-3 (optional), 4) Essence (optional), 5) Mist (optional), 6) Booster/soothing serum (optional), 7) Antioxidant lane — choose ONE, 8) Pigment support lane — choose ONE, 9) Hydration serum lane, 10) Oil-control lane — choose ONE, 11) Peptide/growth-factor lane, 12) Eye product, 13) Moisturizer, 14) Optional sealing layer (dry/AC only), 15) Sunscreen SPF50+ PA++++ (non-negotiable), 16) Lip SPF (optional). In AM, prioritize comfort and SPF adherence over stacking.

PM Maximum Stack: 1) Micellar pre-cleanse (optional), 2) Oil cleanser (if SPF/makeup worn), 3) Water cleanser, 4) pH-prep toner (optional), 5) Hydrating toner layers (optional), 6) Soothing/barrier serum (optional), 7) [Anchor Product — Zero Pore One-Day Peptide Serum], wait 1-3 minutes given the acid/peptide combination, 8) Targeted serum (optional, only if non-conflicting), 9) Moisturizer, 10) Sleeping mask (optional), 11) Occlusive seal (optional), 12) Spot treatment (as needed), 13) Lip sleeping mask (optional). Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany. If unsure, default to the safest lane and reduce layers.

This is a water-thin to light-fluid gel-serum — apply after any watery toner/essence and before moisturizer. It sits in the water phase; the Dimethicone and Cetyl Palmitate fractions give a smoothing, slightly richer finish than the plain Serum, consistent with reviewer reports of a stickier texture.

Phase compatibility: water-phase — always layer this before any oil or heavier silicone-forward product.

Rest days: at least 3-4 nights per week with zero acids. Overuse warning: given this is the strongest formula in the family (four acids, not three), nightly use is more likely than the plain Serum to produce barrier damage — cap at 3x/week if this is your first time using this specific product.

Purging vs. Reaction: PURGING appears in usual breakout zones, stays surface-level, resolves in 4-6 weeks. A REACTION appears in NEW areas, involves burning/swelling/hives, and worsens rather than improves — stop immediately if you see this pattern.

Before starting this product, your routine MUST already include: a consistent daily SPF habit, a gentle cleanser, a plain moisturizer you tolerate well, and ideally prior experience with the plain One-Day Serum or an equivalent acid product. Without these foundations, this is the wrong entry point.

Graduation/demotion ladder: if this is too strong, step down to Zero Pore One-Day Serum (same base without the fourth acid/peptide complex) — verified in stock.

Barrier index gate: if your skin stings on moisturizer or shows visible flaking, your barrier is below threshold. Start with PDRN Pink Hyaluronic Moisturizing Cream for 1-2 weeks first.

Enlarged pores and texture: the quadruple-acid complex (AHA, BHA, PHA, and LHA) dissolves congestion at multiple depths — LHA in particular is a larger-molecule salicylic-acid derivative that's gentler than plain BHA while still working inside the pore. Firmness support: the confirmed peptide fraction (Oligopeptide-1, an EGF-analog signaling peptide, plus Oligopeptide-2/3 and Acetyl Octapeptide-3) is marketed to support the look of skin firmness around stretched pore openings.

What this product cannot do: it cannot physically shrink pore diameter or replace the structural collagen support of a dedicated firming/anti-aging routine — peptide signaling from a leave-on serum is a supportive input, not a substitute for that.

1. PDRN Pink Hyaluronic Moisturizing Cream 50ml — follows this serum to replace drawn-out moisture; PM, always after. Alternates: Zero Pore One-Day Cream (same family), PDRN Pink Collagen Capsule Cream, Exosome Cica Cream.

2. Zero Pore Moisture Sun Serum 50ml — mandatory next-morning SPF. Alternates: Collagen Firming Sun Cream, Glow Collagen Sunscreen, PDRN Hydrating UV Serum.

3. Zero Foam Cleanser 120g — gentle, acid-free cleanse keeps total irritation load manageable. Alternates: Zero Pore Clearing Capsule Cleansing Foam, PDRN Hydrating Gel Cleanser, PDRN Pink Niacinamide Whip Cleanser.

4. PDRN Pink Cica Soothing Toner 250ml — calming on recovery nights. Alternates: PDRN Pink Niacinamide Milky Toner, Zero Pore Pad Mild.

This is a conflict-solver for ACTIVE ingredients. If you run multiple actives, use these rules to avoid irritation, deactivation, and barrier damage.

Universal rule — One Active Lane per routine: run only this serum's exfoliation lane in a single PM routine, not a second strong acid or retinoid the same night.

× Retinoids: never same night — use skin cycling or alternate nights instead.

× L-Ascorbic Acid Vitamin C: don't layer in the same routine, consistent with the base Serum's own brand instruction not to combine with Vitamin C products. Use the classic split: Vitamin C AM, this serum PM.

× A second AHA/BHA/PHA product (e.g. Zero Pore Pad 2.0): avoid stacking two strong exfoliants same night.

Worth flagging honestly: this product's OWN formula already combines direct acids with a marketed peptide complex (including a claimed copper peptide) in one leave-on step. Per general ingredient-conflict guidance, direct acids and copper peptides are normally kept in separate routine steps because low pH can destabilize peptide bonds — this is Medicube's own formulation engineering choice, not something Adilsons can correct, and it means you should NOT then layer a second, separate peptide serum (like Hyaluronic Multi Peptide Serum) immediately after this one; space them to different nights instead.

Scheduling Template (AM/PM Split): AM — antioxidant lane (Vitamin C) → moisturizer → SPF. PM — this serum (exfoliation lane) → moisturizer. Skin-cycling: Night 1 exfoliation (this serum), Night 2 retinoid, Nights 3-4 recovery.

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night. One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany.

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath — resist the urge to overuse this serum during the luteal phase; overuse compounds rather than solves this.

Water-Permeable. A light, water-based gel-serum with only minor Dimethicone/Cetyl Palmitate fractions — it does not form a continuous film that blocks water contact with skin.

Applied and absorbed as directed, water should reach the skin normally during wudu. Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority.

MYTH: "More acids (quadruple vs. triple) always means better results." REALITY: LHA is specifically chosen for being gentler than plain salicylic acid, not stronger — the fourth acid broadens the exfoliation profile rather than simply intensifying it.

MYTH: "If it has peptides, it works like an injectable." REALITY: topical peptides in a leave-on serum act as surface signaling molecules with a much lower and slower effect than an injectable — a supportive input, not a dermatologist-procedure replacement.

AC environment warning: this serum's hyaluronic acid content can draw moisture FROM deeper skin layers in prolonged AC — always seal with a proper moisturizer afterward.

*These ingredients appear below the estimated 1% line in the INCI list, suggesting a trace/sub-efficacious concentration for direct clinical effect, though peptides are conventionally dosed at well under 1% even when functionally active — trace position does not automatically mean ineffective for this ingredient class specifically.

Full INCI: Water(Aqua), Gluconolactone, Methylpropanediol, Glycerin, Propanediol, Tromethamine, Polyglycerin-3, Niacinamide, 1,2-Hexanediol, Citric Acid, Dimethicone, Butylene Glycol, Hydroxyethylcellulose, Salicylic Acid, Sodium Polyacryloyldimethyl Taurate, Lecithin, Allantoin, Lactic Acid, Glycolic Acid, [--- Estimated 1% Line ---] Ethylhexylglycerin, Adenosine, Dextrin, Sodium Hyaluronate, Sodium Citrate, Hemerocallis Fulva Flower Extract, Gardenia Florida Fruit Extract, Trisodium Phosphate, Myosotis Sylvatica Flower/Leaf/Stem Extract, Lactobacillus Ferment Lysate, Taraxacum Officinale (Dandelion) Leaf Extract, Pinus Palustris Leaf Extract, Hydroxypropyltrimonium Hyaluronate, Oenothera Biennis (Evening Primrose) Flower Extract, Acetyl Dipeptide-1 Cetyl Ester, Pentylene Glycol, Caprylyl Glycol, Stellaria Media (Chickweed) Extract, C12-14 Alketh-12, Oligopeptide-2, Oligopeptide-3, Cetyl Palmitate, Indigofera Tinctoria Extract, Lactobacillus Ferment, Oligopeptide-1, Folic Acid, Acetyl Octapeptide-3, Centella Asiatica Extract.

This list is a WebSearch-reconstruction (YesStyle/Korean Beautys listings; direct fetch blocked by network egress) and is INCOMPLETE: brand/Amazon marketing names Copper Tripeptide-1 (GHK-Cu), Acetyl Hexapeptide-1, and LHA (Capryloyl Salicylic Acid) as part of this formula, but none of those three appear by exact INCI name in the list captured this round — an unresolved marketing-vs-INCI gap, not silently assumed present. The 1% line placement is an estimate.

Preservative system: 1,2-Hexanediol and Ethylhexylglycerin, plus Caprylyl Glycol and Pentylene Glycol — a multifunctional glycol-based preservative system, not parabens or formaldehyde-releasers.

Fragrance status: Fragrance-Free — no Fragrance/Parfum entry appears in the reconstructed declared INCI, consistent with the base Serum.

EU 26 allergen screen: None detected in the declared INCI.

Alcohol disclosure: Alcohol-Free — no denatured or drying alcohol identified.

Aspirin sensitivity → Salicylic Acid (BHA) and LHA (a salicylic-acid derivative): this serum contains both a direct BHA and a marketed LHA (Capryloyl Salicylic Acid) — individuals with a genuine salicylate allergy should be extra cautious here versus the plain Serum, since this variant's total salicylate-family exposure is likely higher.

Prescription interactions: if you use prescription tretinoin, adapalene, or isotretinoin, consult your dermatologist before combining — this is the strongest product in the family.

Halal: Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars.

Vegan: Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected in the reconstructed INCI, including the synthetic/biotech peptide fraction; this is NOT a formal vegan certification.

Cruelty-free: Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. Brand states cruelty-free, but sells products in Mainland China retail where post-market animal testing may be required by law. Cross-border e-commerce sales may be exempt.

Microplastic-Free: Yes — no known microplastic-classified polymers identified in the declared INCI.

MFDS classification: not confirmed as Functional Cosmetic — treated as General Cosmetic.

Clinical claim: the brand carries over the same "10.8% reduction in pore appearance after one day" figure marketed for the plain Serum. No separate, peptide-specific clinical figure was found for this upgraded formula, and no study institution, sample size, or methodology was found for the shared figure either.

*This claim is Marketing-Only tier. Treat the pore-reduction number as the same one used for the base Serum, not a distinct result for the peptide upgrade.

Fungal Acne Safety: FA-Conditional. Cetyl Palmitate, present in this formula (not in the plain Serum), is a fatty acid ester some community FA-trackers flag as conditional. The remaining formula (Dimethicone, C12-14 Alketh-12) carries low general FA concern.

Assessment: Medium. The added peptide/ester load versus the plain Serum makes this variant somewhat more prone to pilling under a heavy cream applied too soon.

Mitigation: apply on fully dry skin, wait the full 1-3 minutes, and pat rather than rub the next layer on.

Fresh product should be clear to very slightly opalescent, similar to the plain Serum. Yellowing, a noticeably darker tint, or separation signals the formula has broken down — discard rather than use.

Storage: keep away from direct bathroom-shelf heat and humidity in Mauritius; peptides are generally more heat-sensitive than simple acids, so cooler storage genuinely helps here.

Spoilage signs: color change, separation that won't remix, an off or sour smell. When in doubt, discard.

Patch test: inner forearm for 24 hours, then behind the ear for 24 hours, then begin facial use at reduced frequency (1x/week) for the first two weeks — especially important given this is the strongest product in the family.

If adverse reaction: STOP ALL ACTIVES. For 72 hours, use ONLY gentle cleanser + plain moisturizer + mineral SPF. NO acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72h, reintroduce ONE product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care.

1) Starting here instead of the plain One-Day Serum if you're new to acids. 2) Using it every night instead of 3x/week max. 3) Skipping SPF the next morning. 4) Layering a second peptide serum immediately after, which compounds the pH-vs-peptide tension already built into this formula. 5) Rubbing rather than patting, which increases friction irritation.

Usage math: at 2-3 drops per use, a 30ml bottle holds approximately 300-450 uses.

Lifespan: used 3x/week, one bottle lasts roughly 6-8 months; overusing it nightly would deplete it in under 3 months while increasing barrier-damage risk.

Reorder timing: begin reordering about 2 weeks before estimated depletion.

This is the advanced-tier step in a Zero Pore routine — for someone who has already built tolerance to the plain One-Day Serum and wants the added quadruple-acid/peptide formula. It sits in the exfoliation lane of your PM routine, after cleansing, before moisturizer.

AM: 1) Gentle cleanse, 2) Hydrating toner (optional), 3) Moisturizer, 4) SPF50+ PA++++, mandatory. PM (acid nights, up to 3x/week): 1) Double cleanse if needed, 2) Zero Pore One-Day Peptide Serum — 2-3 drops, pressed in, wait 1-3 minutes, 3) Moisturizer. PM (recovery nights): cleanse, hydrating toner, barrier-support moisturizer only.

If you're new to acids entirely: start with the plain Zero Pore One-Day Serum for 4-6 weeks before graduating to this one. If your skin is barrier-compromised: pause entirely and use only gentle cleanser plus a barrier cream first. If you're already running a separate peptide serum: don't layer it the same night as this one — the acid/peptide tension is already built into this formula, adding more peptide on top doesn't compound the benefit and may irritate.

Stock-true bundle — "Zero Pore Overnight Set": Zero Foam Cleanser + this serum + Zero Pore One-Day Cream + Zero Pore Moisture Sun Serum — verified in stock.

After purchasing, you will receive our skincare education email series covering this product in depth.

The recommendations above are based on formulation synergy with Zero Pore One-Day Peptide Serum, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

If you want peptide support without the acid load, Medicube's own Hyaluronic Multi Peptide Serum 30ml (verified in stock) delivers 13 named peptides with Sodium Hyaluronate and Niacinamide and zero exfoliating acids — a genuinely gentler alternative for firmness-focused goals without the exfoliation risk.

Choose the One-Day Peptide Serum over Hyaluronic Multi Peptide Serum if you need pore-clearing exfoliation and firmness support in one step — the Multi Peptide Serum addresses hydration/firmness only, with no exfoliating acids at all.

Upgrade if: you have genuine pore congestion AND want a firming angle; you already tolerate acid exfoliants well.

Don't upgrade if: your primary concern is pure hydration/firmness with minimal congestion — the Multi Peptide Serum alone, with zero acids, is the lower-risk, sufficient choice.

The full ladder: Zero Pore Pad Mild (gentle PHA-only) → Zero Pore Pad 2.0 (4.5% Lactic + 0.45% Salicylic) → Zero Pore One-Day Serum (15.2% triple acid) → this serum (quadruple acid + peptide complex, the top of the family's strength ladder).

This product's PRIMARY function is: chemical exfoliation plus peptide firming support. You do NOT need this if you already own the plain One-Day Serum AND a separate peptide serum, since this product's role is largely to combine what those two already do.

Inventory audit: check for an already-open acid serum or peptide serum with overlapping function before buying this one.

Stacking assessment: against the plain One-Day Serum — No Benefit if run concurrently (same acid lane, redundant). Against Hyaluronic Multi Peptide Serum — Marginal Benefit if you already own both, since this product's own peptide fraction already covers similar ground.

Quick verification tips: genuine Medicube packaging carries a QR code on the inner box that resolves to medicubeverify.com with a green checkmark; check for a clean, legible embossed batch code; label print quality should be sharp with no spelling errors.

Medicube positions itself as a "medical beauty" brand. This peptide variant illustrates the brand's pattern of layering marketing-forward ingredient names (a "10-peptide complex," "quadruple acid") onto an existing formula — some of which we could independently confirm in the INCI and some (Copper Tripeptide-1, Acetyl Hexapeptide-1) we could not this round, worth knowing as a shopper rather than taking every marketed name at face value.

A Hwahae reviewer reported their skin felt "more elastic and firm and bouncy" after use — a positive result consistent with the marketed peptide-firming angle, though individual and not independently verified.

Another Hwahae reviewer described the texture as "extremely sticky even after applying cream on top," recommending it as a PM-only treatment rather than a pre-makeup step — this contrasts with at least one plain-Serum reviewer who used that sibling product successfully as a makeup primer, suggesting the peptide variant's texture genuinely differs and reads stickier for more users.

Common praise theme: improved firmness/bounce reported by some users. Common complaint theme: stickier finish than the plain Serum, more consistently reported across reviewers for this specific variant.

Sustainability: glass components are recyclable through standard glass recycling where available in Mauritius; separate the dropper's rubber and plastic parts first. Not a refillable format.

How is this different from the plain Zero Pore One-Day Serum? This variant adds LHA as a fourth acid and a marketed 10-peptide complex on the same triple-acid, 2% Niacinamide base — it's the "upgraded" version for those who've already built tolerance.

Should I start here or with the plain Serum? Start with the plain Serum if you're new to acid exfoliants; this variant is the graduated, stronger option.

Does it really contain copper peptide (GHK-Cu)? The brand's marketing names Copper Tripeptide-1, but it was not found by exact INCI name in this research pass — treat that specific ingredient claim as unresolved rather than confirmed.

Can I combine it with a separate peptide serum? Not the same night — the formula already combines acids with peptides internally; adding a second peptide product on top doesn't compound the benefit.

Why does it feel stickier than the regular serum? The added ester/peptide load (including Cetyl Palmitate, not present in the plain Serum) gives this variant a richer, tackier finish per multiple independent reviews.

LHA

Lipohydroxy acid (Capryloyl Salicylic Acid) — a larger-molecule, gentler cousin of salicylic acid.

Peptide

A short chain of amino acids that signals skin cells to perform specific functions, like supporting firmness.

Oligopeptide-1

A peptide functioning as an EGF (epidermal growth factor) analog, signaling skin cells to renew.

Copper peptide (GHK-Cu)

A copper-bound tripeptide studied for skin-repair signaling — its presence in this specific formula is unconfirmed by INCI name.

AHA / BHA / PHA

Alpha, beta, and polyhydroxy acids — three exfoliant families that work at different depths and molecule sizes.

Barrier

The skin's outermost protective layer; when damaged it causes stinging, tightness, and flaking.

Source of Truth: This is a quick snapshot. If anything differs, the policy pages are final.

Store Policies: For the most up-to-date information, please review our Shipping Policy and Refund Policy.

Best for: someone who has already used and tolerated the plain Zero Pore One-Day Serum (or an equivalent acid product) well and wants an added peptide-firming angle in the same overnight step.

Key benefits: confirmed signaling peptides (Oligopeptide-1/2/3, Acetyl Octapeptide-3), broader four-acid exfoliation coverage via LHA, fragrance-free, shares the family's 2% Niacinamide.

Keep in mind: two marketed peptide names weren't confirmed by INCI in this research pass, texture reads stickier than the plain Serum per multiple reviewers, and this is the highest-risk, highest-strength product in the Zero Pore One-Day family — not a first acid serum.

Assessment: Not Suitable. Although fragrance-free, the quadruple-acid load plus active peptide signaling ingredients make this the least appropriate product in the family for treatment-sensitized skin, which is typically more fragile and slower to heal.

A gentler barrier-support option, such as PDRN Pink Hyaluronic Moisturizing Cream, is a more appropriate category during active treatment.

Consult your oncology care team before introducing any new skincare products during treatment.

Quick version: Week 1-2, introduce alone at 1x/week and monitor. Week 3-4, increase to 2x/week if stable. Week 5+, hold at up to 3x/week maximum. If irritation appears, use the 72-Hour Barrier Reset rather than pushing through.

This product must be introduced as the ONLY new product. Wait 14 days before adding anything else.

AC/humidity swing interaction: this serum's hyaluronic acid content can pull moisture from deeper skin layers rather than the (dry) surrounding air during long AC exposure — always follow with a proper moisturizer.

Impact: Neutral-to-Supportive. The formula contains Lactobacillus Ferment and Lactobacillus Ferment Lysate — POSTBIOTICS, beneficial metabolites from fermentation. You are not applying live bacteria; the yeasty/fermented character some ingredients carry is normal and indicates genuine ferment filtrate, not spoilage.

End of Week 2 decision point: any persistent redness or burning? YES — stay at Week 1-2 frequency for 2 more weeks. NO — proceed to Week 3.
