MARY&MAY 6 PEPTIDE COMPLEX SERUM 30ML

Values: 100% Genuine (Adilsons policy) · Fragrance-Free (confirmed by INCI) · FA-Conditional (see Section 24/30) · Vegan-Friendly* (self-assessed) · Halal-Friendly* (self-assessed)

If you've noticed skin that looks a little less bouncy than it used to but isn't showing deep lines yet, this serum is built for that early-maintenance stage rather than for reversing established wrinkles.

Pros: genuinely non-sticky watery texture that layers under anything; fragrance-free and low-ingredient-count, good for reactive skin; usable AM and PM; brand transparently discloses exact peptide concentrations instead of hiding behind "peptide complex" marketing.

Caveats: 2ppm per peptide is a trace dose — some reviewers report no visible change after weeks of use; contains an FA-conditional emulsifier (see Section 30) worth noting if you are fungal-acne-prone; not a substitute for retinoids if you need stronger collagen stimulation.

Classification: GREEN — nothing in this formula is irritating or age-restricted; peptides and Adenosine carry no known safety concern for younger skin. That said, this product is not really needed before the mid-to-late 20s, when the skin's own collagen synthesis rate begins its gradual natural decline — a 15-year-old's skin is not yet in the phase this serum is designed to support.

There is no youth-targeted packaging or marketing on this SKU, so this is a relevance note rather than a safety warning: a teenager can use it without harm, but the value is mostly wasted until skin actually starts losing firmness.

Bedside-compatible: yes. Requires rinsing: no. Requires precise dosage: no — 2-3 drops by feel. Works with unwashed hands: yes, since it is not pH-dependent like an acid. Wait time needed: 30-60 seconds before the next step, or none if it is your last step before sleep.

It qualifies for a bare-bones routine (cleanser optional if skin isn't dirty, this serum, moisturizer) on days when a full multi-step routine feels like too much. Its light, watery texture is also the least likely product in a routine to feel heavy or "too much" when you are already overwhelmed.

Step 1 — When: AM or PM, or both.

Step 2 — How much: 2-3 drops, or one full dropper if the bottle uses a dropper.

Step 3 — How: Pat gently into slightly damp, cleansed skin; do not rub.

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.

1. Gentle cleanse (optional). 2. Hydrating toner (optional, 1 layer). 3. Antioxidant step if used (e.g. a Vitamin C serum — see the Conflict Solver below before combining with this product). 4. MARY&MAY 6 Peptide Complex Serum — 2-3 drops, pat in, wait 30-60 seconds. 5. Moisturizer. 6. Sunscreen SPF50+ PA++++ (non-negotiable).

In Mauritius's humid mornings, this serum's humectant base (Glycereth-26, Glycerin, Butylene Glycol) draws ambient moisture toward the skin surface rather than pulling it from deeper layers — a genuine climate advantage over drier, more occlusive anti-aging creams. It carries no known photosensitizing ingredients, so there is no AM restriction on its own — but sunscreen is still mandatory, since UV damage undoes any collagen-support benefit this serum offers.

1. Double cleanse if wearing sunscreen/makeup. 2. Hydrating toner (optional). 3. MARY&MAY 6 Peptide Complex Serum — 2-3 drops, pat in, wait 30-60 seconds. 4. Any targeted treatment that doesn't share this product's lane (see Conflict Solver). 5. Moisturizer.

If you are running a 4-night skin-cycling routine with exfoliation and a retinoid, this peptide serum fits comfortably into the two "Recovery" nights alongside your moisturizer — it adds barrier-friendly support without adding to the active load.

Technique: Pat/press into skin — do not rub. Friction degrades the delicate peptide structures and increases irritation risk for no benefit.

Required skin state: slightly damp skin (post-toner) helps this watery serum spread evenly. Wait time: 30-60 seconds before your next step. Hands deliver 100% of product; cotton pads absorb approximately 30-40% — use hands for this serum.

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: apply 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 minutes if going outdoors. Amount defaults: watery 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. Hydrators sit best on slightly damp skin; if the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: 1. Rinse/Gentle Cleanse (optional). 2. pH-Prep Toner (optional). 3. Hydrating Toner Layers (optional, 1-3). 4. Essence (optional). 5. Mist (optional). 6. Booster/Soothing Serum (optional). 7. Antioxidant Lane — choose ONE (L-Ascorbic Acid Vitamin C or a gentler antioxidant). 8. Pigment Support Lane (optional). 9. Hydration Serum Lane (optional). 10. Oil-Control Lane (optional). 11. Peptides/Repair Lane (this product sits here) — 2-3 drops, wait 30-60s; if using pure L-Ascorbic Acid Vitamin C elsewhere in the routine, keep this peptide step for PM instead. 12. Eye Serum/Cream (optional). 13. Moisturizer. 14. Optional Sealing Layer (dry/AC days only). 15. Sunscreen SPF50+ PA++++ (non-negotiable). 16. Lip SPF (optional).

In AM, prioritize comfort and SPF adherence over stacking. In high humidity, fewer layers often perform better.

PM Maximum Stack: 1. Micellar pre-cleanse (optional). 2. Oil Cleanser/Balm (if SPF/makeup worn). 3. Water Cleanser. 4. pH-Prep Toner (optional). 5. Hydrating Toner Layers (optional). 6. Essence (optional). 7. Soothing/Barrier Serum (optional). 8. [Anchor: 6 Peptide Complex Serum] — 2-3 drops, wait 30-60 seconds. 9. Targeted Serum (optional, only if non-conflicting). 10. Moisturizer. 11. Sleeping Mask (optional). 12. Occlusive Seal (optional). 13. Spot Treatment (as needed). 14. 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 and peptides can always accompany. If unsure, default to the safest lane and reduce layers.

Tier: Water-thin fluid — sits early in your serum stack, applied after any toner/essence but before thicker treatment serums or moisturizer.

Phase: Fully water-phase, no oils or silicones in the declared INCI, so it layers cleanly beneath both water-based and oil-based products without separation. Because it is genuinely thin rather than thickened-to-feel-rich, apply it before any lotion, cream, or oil step in your routine, not after.

Unlike exfoliating acids or retinoids, this peptide serum has no maximum-frequency restriction — it is designed for daily AM and/or PM use, with no rest days required. The only scheduling consideration is timing relative to Vitamin C (see the Conflict Solver below), not frequency.

There is no overuse ceiling in the exfoliant sense, but using more than 2-3 drops per application does not accelerate results — it only wastes product, since the peptide dose per drop is fixed by the formula, not by how much you apply.

Prerequisites: before starting this product, your routine should already include a daily SPF habit — peptide-driven collagen support is undone by unprotected UV exposure, which breaks collagen down faster than any serum can support it.

Loss of firmness / early fine lines: the six peptides signal fibroblasts toward collagen and elastin production, working alongside (not replacing) the skin's own repair processes. Dullness/tiredness: Adenosine is an MFDS-recognized wrinkle-improvement ingredient in Korea generally, though this SKU's exact Adenosine concentration was not disclosed.

What this product cannot do: it cannot lift sagging skin structurally, cannot replace the collagen-stimulating strength of a retinoid or in-office treatment, and cannot reverse deep, established static wrinkles — its role is early support and maintenance, not correction.

1. Sunscreen (mandatory anchor). Primary: SKIN1004 Madagascar Centella Tone Brightening Tone-Up Sunscreen 50ml. Alternatives: Beauty of Joseon Matte Sun Stick, ROUND LAB Birch Juice Tone Up Sunscreen, TOCOBO Cotton Soft Sun Stick. UV protection is what preserves the collagen this peptide serum is helping support.

2. AM antioxidant partner (time-separated from this serum — see Conflict Solver). Primary: Dr.Althea Gentle Vitamin C Serum. Alternatives: ARENCIA Vitamin C Booster Shot, Anua Vitamin C 20 Blemish Serum, SOME BY MI Galactomyces Pure Vitamin C Glow Serum.

3. Moisturizer to seal. Primary: Beauty of Joseon Dynasty Cream. Alternatives: Anua Birch Moisture Boosting Cream, SKIN1004 Probio-Cica Enrich Cream, COSRX Advanced Snail 92 All In One Cream.

4. In-brand barrier companion. Primary: MARY&MAY Centella Asiatica Serum. Alternatives: MIXSOON Centella Asiatica Toner, One Thing Centella Asiatica Serum, Beauty of Joseon Centella Asiatica Calming Mask.

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

Copper Peptide × L-Ascorbic Acid Vitamin C: copper ions accelerate oxidation of pure Vitamin C, and Vitamin C's low pH can destabilize the peptide bonds in this serum. Do not layer them in the same routine. Instead: Vitamin C AM / this peptide serum PM, or alternate days.

Copper Peptide × Direct Acids (AHA/BHA): low pH from acid exfoliants can similarly destabilize peptide bonds if applied immediately before or after. Instead: peptides AM, acids PM — or wait at least 20 minutes between the two if used in the same routine.

Barrier override: if your moisturizer stings or your skin feels tight within 30 minutes of cleansing, pause all actives (including this serum) and run barrier-only care for 3-7 days before resuming.

Water-Permeable (Wudu-Compatible). This is a thin, fast-absorbing, oil-free water serum with no waxes, silicones, or film-forming polymers in the declared INCI — it does not sit on skin as a barrier film.

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 peptides in the ingredient list means a stronger anti-aging effect." REALITY: concentration matters more than count — this product discloses six peptides at 2ppm each, which is transparent but modest, not automatically superior to a formula with fewer peptides at a higher dose.

MYTH: "Peptide serums work like retinol, just gentler." REALITY: peptides signal cells toward collagen production through a different pathway than retinoids' cell-turnover mechanism — they are complementary, not interchangeable, and peptides generally show a slower, subtler effect profile.

AC environment warning: in air-conditioned environments, the humectants in this serum (Glycereth-26, Glycerin, Butylene Glycol) can draw moisture FROM your deeper skin layers instead of from the air if left unsealed. Always follow with a moisturizer when spending extended hours in AC.

Hard water note: Mauritius tap water hardness varies by region; if your cleanser leaves a tight, filmy feeling, a pH-adjusting toner before this serum helps counteract that residue so the serum absorbs evenly.

*Evidence for the four supporting peptides (Hexapeptide-9/11, Palmitoyl Tripeptide-1, Tripeptide-1) is drawn from general cosmetic-peptide literature rather than large-scale independent clinical trials on these specific molecules at this concentration.

Full INCI: Purified Water, Glycereth-26, 1,2-Hexanediol, Butylene Glycol, Glycerin, Arginine, Carbomer, Ethylhexylglycerin, Polyglyceryl-10 Laurate, [--- Estimated 1% Line ---] Adenosine, Caprylyl Glycol, Copper Tripeptide-1 (2ppm), Hexapeptide-11 (2ppm), Hexapeptide-9 (2ppm), Palmitoyl Pentapeptide-4 (2ppm), Palmitoyl Tripeptide-1 (2ppm), Tripeptide-1 (2ppm).

Every peptide sits below the estimated 1% line, but the brand discloses each one's exact 2ppm concentration rather than hiding behind an undisclosed "peptide complex" — this is a transparency positive even though the individual dose is modest.

Preservative system: 1,2-Hexanediol, Ethylhexylglycerin, and Caprylyl Glycol form a multi-functional humectant/preservative-booster system — a common alternative to traditional parabens/phenoxyethanol in modern K-beauty formulas.

Fragrance status: Fragrance-Free — confirmed by the declared INCI (no Parfum/Fragrance listed). Scent: no detectable scent reported by reviewers. EU 26 allergen screen: none detected in the declared INCI. Alcohol disclosure: Alcohol-Free — no drying alcohols (denatured/SD alcohol) present.

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. This is NOT a formal vegan certification by The Vegan Society or equivalent body. Note: Mary&May markets itself broadly as a vegan brand, but at least one other SKU in this line (the Tranexamic Acid+Glutathione Eye Cream) contains Beeswax — this assessment is specific to this product's own declared INCI, not inherited from brand-wide marketing.

Cruelty-Free: *Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. Mainland China retail exposure for this brand specifically was not resolved during research.

Microplastic-Free: Yes — no polymer microbead ingredients detected in the declared INCI (Carbomer is a rheology modifier, not a microplastic).

MFDS classification: not independently confirmed as a registered Functional Cosmetic for this specific SKU. "Functional" in Korea means the product underwent additional government testing for a specific claim (whitening, wrinkle improvement, or UV protection) — Adenosine is a recognized wrinkle-improvement ingredient generally, but this product's own registration status was not found.

Clinical evidence: the peptide mechanisms described above come from general cosmetic-peptide research literature, not a study commissioned on this exact 30ml formula. *Clinical evidence is based on in-vitro (lab cell) and general ingredient-class studies rather than an in-vivo trial on this specific product. This does not mean the ingredients are ineffective — it means the evidence tier is lower than a brand-commissioned human trial. Evidence confidence: Medium.

Fungal Acne Safety: FA-Conditional. The declared INCI contains Polyglyceryl-10 Laurate, a lauric-acid-chain polyglyceryl ester. Some fungal-acne-safety reference screens flag lauric-acid-derived esters as a possible Malassezia food source for a subset of FA-prone users, though polyglyceryl esters are generally considered lower-risk than plain fatty-acid esters — if you are strictly FA-prone, patch test on a small breakout-prone area first.

Assessment: Low. As a water-thin, oil-free, non-film-forming serum, this product is unlikely to ball up under other layers. Pilling risk increases only if applied over already-thick, unabsorbed layers (e.g. a heavy cream) — apply it earlier in your stack, before thicker products, to avoid this.

Fresh product should remain clear to very lightly tinted and odorless. A noticeable color shift, a sour or "off" smell, or visible separation are all spoilage signs — discard if any appear, since oxidized peptide/humectant formulas can lose efficacy without necessarily becoming harmful, but degraded actives simply stop doing their job.

Storage: keep away from direct bathroom humidity and heat where possible — Mauritius's ambient heat can accelerate degradation of any water-based serum faster than temperate-climate storage. Keep the cap tightly closed between uses.

Patch test: apply a small amount to your inner forearm, wait 24 hours; if clear, apply behind the ear, wait another 24 hours; then begin facial use.

72-hour barrier reset (if you react): stop all actives. For 72 hours, use ONLY a gentle cleanser, plain moisturizer, and mineral SPF — no acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately if any of these occur.

1. Layering this serum directly with a pure Vitamin C serum in the same routine — see the Conflict Solver above. 2. Applying more than 2-3 drops expecting faster results — the peptide dose per drop is fixed. 3. Rubbing it in vigorously — pat instead. 4. Skipping SPF because "the serum is anti-aging enough" — UV damage outpaces any peptide-support benefit. 5. Expecting retinoid-level results — this is a gentler, slower-acting support product.

At 2-3 drops per application, once or twice daily, a 30ml bottle provides roughly 150-250 applications. Used once daily, that is approximately 5-8 months; used twice daily (AM and PM), approximately 2.5-4 months.

Applying more than the recommended 2-3 drops does not improve results, since the peptide dose is fixed per drop by the formula — it only shortens how long the bottle lasts. Consider reordering roughly 2-3 weeks before you expect to run out, to allow for shipping time.

This serum's role is early collagen/elastin support — apply after your thinnest hydrating layers and before moisturizer, AM or PM. AM: Cleanse → Toner (optional) → Antioxidant step if used → 6 Peptide Complex Serum → Moisturizer → Sunscreen. PM: Cleanse → Toner (optional) → 6 Peptide Complex Serum → Moisturizer.

If you are also using a Vitamin C serum, keep this peptide serum for PM to avoid the oxidation/destabilization conflict described above. If you spend most of your day in air-conditioning, seal this serum with a slightly richer moisturizer than you would use in humid outdoor conditions. If you are new to actives entirely, this is a reasonable starting point precisely because its trace peptide dosing carries low irritation risk.

Stock-true bundle — Anti-aging AM/PM set: MARY&MAY 6 Peptide Complex Serum (PM anchor) + Dr.Althea Gentle Vitamin C Serum (AM antioxidant) + Beauty of Joseon Dynasty Cream (moisturizer) + SKIN1004 Tone Brightening Sunscreen (AM seal). Alternate Vitamin C and moisturizer options are listed in Section 15 above if any of these are out of 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 the 6 Peptide Complex 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 an anti-aging serum from the same brand built on a different mechanism (antioxidant protection rather than peptide signaling), consider MARY&MAY Idebenone+Blackberry Complex Serum — it targets free-radical damage rather than collagen signaling, and the two can even be alternated AM (antioxidant) / PM (peptide) rather than treated as either/or.

Choose the 6 Peptide Complex Serum over the Idebenone+Blackberry Complex Serum if you need: collagen/elastin-signaling support rather than antioxidant free-radical defense — these are complementary mechanisms, not competing strength tiers.

If your priority is antioxidant defense (pollution, sun-stress, general free-radical protection), the Idebenone+Blackberry Complex Serum is the better single pick. If your priority is collagen/firmness signaling, stay with this peptide serum. Many users benefit from rotating both rather than choosing only one — they do not compete for the same lane.

Don't upgrade / switch if: you are already using a retinoid successfully (adding either serum on top is a supporting layer, not a replacement); you are budget-conscious and only want one anti-aging serum (either alone is a reasonable single choice); you have not yet built a consistent SPF habit (neither serum's benefits hold up without daily sun protection).

This product's PRIMARY function is: peptide-based collagen/elastin signaling support. You do NOT need this if you already own another peptide serum you are using consistently and it is working — finish your current product before purchasing a second peptide serum.

Stacking assessment: pairing with a Vitamin C serum (time-separated) or a soothing Centella serum is Significant Benefit (different pathways). Pairing with another collagen-peptide serum is No Benefit (same mechanism) — pick one.

Brand Name: MARY&MAY. Headquarters: Seoul, South Korea. Philosophy: "Less but Better" — fewer ingredients, simpler formulas, targeted actives, positioned as a clean-beauty brand (parabens, artificial colors, and unnecessary fragrance excluded from most of its formulas). Product model: a lineup of single-active-pairing serums and creams (this Peptide Complex, plus Tranexamic Acid+Glutathione, Idebenone+Blackberry, Centella Asiatica, Marine Collagen, and Niacinamide+Chaenomeles Sinensis lines) rather than one overarching hero ingredient.

No conglomerate parent company was identified for Mary&May during research, and whether manufacturing is in-house or contract-based was not confirmed. The brand's marketing leans on genuinely short ingredient lists — this serum's 17-ingredient INCI and its sibling Niacinamide+Chaenomeles Sinensis Serum's 8-ingredient INCI both support that positioning, though the brand's blanket vegan claims do not hold for every SKU (see Vegan disclosure above).

Across iHerb listings, independent blog reviews (What's In My Jar, Reviewed by Hanna), Walmart, and skincare-aggregator sites, the recurring positive theme is texture: reviewers repeatedly describe this serum as unusually light and non-sticky for a peptide product, with several noting it can be worn overnight without transferring to a pillow or hair — a genuine differentiator from thicker, tackier peptide serums.

A mixed theme also appears: some reviewers report no noticeable firming change even after weeks of consistent use, which is plausible given the brand's own disclosed 2ppm-per-peptide dosing. A smaller minority with sensitive skin reported red bumps and itching and discontinued use — a real, if minority, signal worth disclosing rather than omitting, even though the majority of findable reviews describe it as gentle. No dedicated Reddit thread specific to this exact product was located during this research pass.

Sustainability: check local recycling guidance for the glass/plastic bottle and dropper components separately; the product itself is not refillable.

Can I use this with retinol? Yes — peptides and retinoids work through different pathways and are commonly used together, typically peptides layered before a lighter moisturizer step and retinol as your PM active on non-peptide-conflicting nights.

Will this actually firm my skin? Realistically, expect subtle, gradual support rather than a dramatic lift — the brand's own 2ppm-per-peptide disclosure means this is a maintenance-tier product, not a clinical-strength treatment.

Can I use it with Vitamin C? Not in the same application — see the Conflict Solver above for the AM/PM split.

Is it safe for acne-prone skin? Generally yes — it's oil-free and fragrance-free — but check the FA-Conditional note if you specifically react to fungal-acne triggers.

Does it have a scent? No — it is formulated fragrance-free and reviewers consistently describe it as scentless.

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 in their late 20s onward who wants a gentle, low-irritation entry point into peptide-based anti-aging support, especially if they dislike heavy or tacky serums and live somewhere humid.

Key benefits: fragrance-free and oil-free with a genuinely watery, non-sticky texture; brand-transparent peptide dosing rather than a vague "complex" claim; usable AM and PM with no cycling restrictions.

Keep in mind: 2ppm per peptide is a trace, maintenance-level dose — do not expect retinoid-level firming; must be time-separated from Vitamin C; contains one FA-conditional ingredient worth a patch test if you're fungal-acne-prone.

Assessment: Likely Suitable, with medical guidance. This formula is fragrance-free, retinoid-free, and uses a minimal, common preservative-booster system rather than aggressive actives.

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

Antioxidant pollution defense: Copper Tripeptide-1 (GHK-Cu) has documented antioxidant activity in general peptide literature alongside its collagen-signaling role, offering a secondary layer of free-radical defense relevant to Mauritius's coastal UV and, during July-November, sugar cane burning season particulate exposure.

AC/humidity swing interaction: because this serum's texture depends on humectants (Glycereth-26, Glycerin, Butylene Glycol) rather than oils, extended air-conditioned exposure can leave it pulling moisture from deeper skin layers if left unsealed — always follow with a moisturizer during long AC hours.
