Dear Klairs Vitamin PDRN Bouncy Pore Serum 35 ml

Values you can trust: 100% Genuine (Adilsons policy) · Fragrance-Free (confirmed, no Parfum in the declared INCI) · Alcohol-Free (no drying/denatured alcohol detected) · Cruelty-Free (brand listed on PETA's own cruelty-free company database)*.

*Brand appears by name on PETA's own cruelty-free company database, cross-checked via multiple independent trackers; direct verification of PETA's live page was blocked by network access at research time.

Pros: genuinely multi-functional (pore, glow, elasticity, hydration in one step), fragrance- and alcohol-free, lightweight for a multi-active formula. Caveats: individual active concentrations (Vitamin C forms, Sodium DNA, peptides) are not brand-disclosed, no dedicated third-party clinical trial for this exact SKU was found, and it does occupy the Vitamin C active lane — it should not be layered with another strong Vitamin C or retinoid product same-session.

This can anchor a bare-bones routine (cleanser, this serum, moisturizer) since it packs several functions into one step, though it does require a brief 30-60 second absorption wait before moisturizer, unlike a true zero-wait product.

The lightweight, non-sticky texture means it carries low sensory-aversion risk even on low-energy or overstimulated days.

Step 1 — When: AM and/or PM, after cleansing and toning.
Step 2 — How much: 2-3 drops or 1 pump, pressed into the face (add 1 more drop for the neck if used there).
Step 3 — How: press/pat into skin, wait 30-60 seconds before your next serum or 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.

1. Gentle cleanser (optional). 2. Hydrating toner. 3. Vitamin PDRN Bouncy Pore Serum, 2-3 drops. 4. Moisturizer. 5. Sunscreen (mandatory — Vitamin C's antioxidant benefit is best paired with, not substituted for, daily SPF). In Mauritius' humid mornings, this serum's light texture absorbs fast enough to layer cleanly under sunscreen.

This is your Vitamin C lane for the day — if you also use a separate Vitamin C serum, use only one of the two per session, not both.

1. Double cleanse if wearing sunscreen/makeup. 2. Toner. 3. Vitamin PDRN Bouncy Pore Serum. 4. Moisturizer, plus an occlusive seal if skin runs dry.

Skin cycling integration: if you also run a retinoid or acid exfoliant, keep this serum on its own night or apply it on your recovery nights rather than stacking it with a fresh retinoid/acid application — see the Conflict Solver below for the full logic.

Press/pat rather than rub, especially given the Vitamin C content — friction can increase sensitivity on reactive skin. Apply to slightly damp skin for faster spread, or dry skin if layering under makeup.

Hands deliver 100% of product. Cotton pads absorb approximately 30-40%. Use fingertips to get the full intended dose.

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 runs thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serum layers 30-60s, sunscreen 10-15 minutes before sun/makeup. Amount defaults: watery toner 5-8 drops, serum 2-3 drops, gel moisturizer 1-1.5 peas, cream 1-2 peas, sunscreen 2-finger rule for face plus 1 finger for neck. If the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: (1) optional gentle cleanse, (2) pH-prep toner, (3) hydrating toner layers, (4) essence, (5) mist, (6) soothing serum, (7) antioxidant lane — this product's Vitamin C complex sits here, (8) pigment-support lane (pick one, skip if already covered above), (9) hydration serum lane, (10) oil-control lane, (11) peptide/repair lane (this product's peptides also contribute here), (12) eye product, (13) moisturizer, (14) optional occlusive seal, (15) sunscreen, (16) lip SPF. In AM, prioritize comfort and SPF adherence over stacking.

PM Maximum Stack: (1) micellar pre-cleanse if needed, (2) oil cleanser, (3) water cleanser, (4) pH-prep toner, (5) hydrating toner layers, (6) essence, (7) soothing serum, (8) anchor active product (a retinoid or acid, on nights you're not using this serum's Vitamin C lane), (9) targeted serum, (10) moisturizer, (11) sleeping mask, (12) occlusive seal, (13) spot treatment, (14) lip sleeping mask. 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. This product's Vitamin C content means it counts as your Vitamin C lane for the day.

This sits as a light-to-medium serum — apply after watery toners/essences, before thicker treatment serums or moisturizer.

Phase compatibility: primarily water-phase, with Carbomer and Polyacrylate Crosspolymer-6 as gelling agents giving it slightly more body than a pure water-thin serum; it layers cleanly under both water- and oil-based products.

Before starting this product, your barrier should be in reasonably good shape — the multi-active load (Vitamin C, niacinamide, peptides) is gentle by K-beauty standards but is not a bare-minimum barrier-repair product.

Enlarged pore appearance: the humectant/hydrating base plumps surrounding skin, optically softening the look of pores rather than physically shrinking them. Dullness/glow: the 5-form Vitamin C complex and Niacinamide support tone evenness. Elasticity support: Sodium DNA (marketed PDRN), Adenosine, and the peptide trio (Acetyl Hexapeptide-1/-8, Copper Tripeptide-1) are marketed for skin-conditioning/firmness support. PIH vs PIE: the Vitamin C/niacinamide combination is positioned for brown, pigment-based marks (PIH) — it does not address red/pink post-inflammatory marks (PIE), which respond better to centella-forward or time-based recovery.

What this product cannot do: it cannot physically shrink pore size (no cosmetic product can — pores are structural), cannot lighten your natural skin tone beyond fading excess pigment, and cannot replace a dedicated exfoliant for textural pore congestion.

Every pairing below is verified in Adilsons' live catalog as status: active with real stock at the time of writing (stock levels change — see the closing note).

AM Sunscreen (mandatory partner for a Vitamin C serum): primary — SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum. Alternatives: Beauty of Joseon Relief Sun: Rice + Probiotics, Anua Heartleaf Silky Moisture Sun Cream, Round Lab Birch Juice Moisturizing Tone Up Sunscreen.

Hydrating toner (prep layer underneath): primary — MIXSOON Centella Asiatica Toner. Alternatives: SKIN1004 Madagascar Centella Toning Toner, Anua Rice 70 + Ceramide Glow Milky Toner, AXIS-Y Dark Spot Correcting Glow Toner.

Moisturizer (seals this serum in): primary — SKIN1004 Madagascar Centella Probio-Cica Enrich Cream. Alternatives: Anua Birch Moisture Boosting Cream, Beauty of Joseon Dynasty Cream, Anua Peach 77% Niacin Conditioning Milk.

Pilling risk: low-to-moderate if layered with another gel-textured serum containing Carbomer/acrylate thickeners — space layers with a full 60-second wait if you notice balling.

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

One Active Lane per routine: in a single AM or PM routine, run only one primary active lane — this product occupies the Vitamin C lane. Barrier override: if moisturizer stings or skin feels tight within 30 minutes of cleansing, pause all actives and run barrier-only for 3-7 days.

× Benzoyl Peroxide (BPO): never combine — BPO oxidizes and destroys Vitamin C activity. Instead: use this serum AM, BPO PM (or alternate days).

× Copper Peptides in a SEPARATE product: this serum already contains its own Copper Tripeptide-1, so avoid also layering a separate strong copper-peptide product in the same session — copper ions can accelerate Vitamin C oxidation. Instead: alternate AM/PM or alternate days.

× AHAs/BHAs (separate products): avoid layering directly — excess acidity can sting. Instead: use this serum AM, acids PM; or if insisting on layering, wait 15-20 minutes between them.

× Retinoids: don't layer in the same routine. Instead: this serum AM, retinoid PM (the classic split), or alternate nights if both are meant for PM.

Scheduling template (AM/PM split, most common): AM — this serum (Vitamin C/antioxidant lane) → Moisturizer → SPF. PM — Retinoid OR Acid lane → Moisturizer.

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night. If unsure, default to the safest lane — barrier/hydration — and reduce layers.

This product is Water-Permeable (wudu-compatible) — a light gel-serum that absorbs into skin without leaving a persistent occlusive 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: "This serum will physically shrink my pores." REALITY: pore size is structural (genetics, sebum volume); this serum plumps surrounding skin to make pores look smaller, not smaller in fact.

MYTH: "PDRN in skincare is the same as medical PDRN injections." REALITY: this is a topical Sodium DNA cosmetic ingredient, not the injectable salmon-DNA treatment used in clinics — the mechanism and evidence tier are very different.

Antioxidant pollution defense: this formula carries a genuinely broad antioxidant stack — five Vitamin C derivatives, Astaxanthin, and Niacinamide — that plausibly helps neutralize free-radical stress from UV and airborne particulates, though this is a supportive claim rather than a clinically dosed anti-pollution treatment.

*Evidence for several of these ingredients (Sodium DNA, the peptide trio, Astaxanthin) at the concentrations used in this specific formula is still an emerging research area; treat brand claims as plausible but not independently proven for this exact SKU.

Full INCI (as retrieved from a CosDNA ingredient-analysis listing for this exact 35ml product; WebFetch access to cosdna.com was blocked at research time): Water, Butylene Glycol, Glycerin, [--- Estimated 1% Line ---] Niacinamide, 1,2-Hexanediol, Sodium DNA, Arginine, Carbomer, Polyacrylate Crosspolymer-6, Caesalpinia Spinosa Fruit Extract, Ethylhexylglycerin, Caprylyl Glycol, Adenosine, Kappaphycus Alvarezii Extract, Sodium Phytate, Polyglyceryl-10 Laurate, Glyceryl Acrylate/Acrylic Acid Copolymer, Polyglyceryl-4 Laurate, Nicotinamide Mononucleotide, Pvm/Ma Copolymer, Caprylyl/Capryl Glucoside, Prunella Vulgaris Extract, Opuntia Ficus-Indica Fruit Extract, Fucus Vesiculosus Extract, Centella Asiatica Extract, Disodium EDTA, Acetyl Hexapeptide-1, Acetyl Hexapeptide-8, Copper Tripeptide-1, Hydrogenated Lecithin, Ascorbic Acid, 3-O-Ethyl Ascorbic Acid, Sodium Ascorbyl Phosphate, Ascorbyl Glucoside, Ascorbyl Palmitate, Octyldodecanol, Astaxanthin.

Preservative system: 1,2-Hexanediol, Ethylhexylglycerin, Caprylyl Glycol, and Disodium EDTA (chelator, not itself a preservative but commonly paired with one) — a multifunctional glycol-based system; no parabens or phenoxyethanol detected in the retrieved list.

Fragrance status: Fragrance-Free — no Parfum/Fragrance listed in the retrieved INCI.

Scent: no added fragrance ingredient; any faint smell would come from raw-material notes rather than perfume.

EU 26 allergen screen: none detected in the declared INCI retrieved for this research pass.

Alcohol disclosure: Alcohol-Free — no denatured or drying alcohol detected in the retrieved list.

Halal:* Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation and no explicitly porcine-derived ingredients detected in the declared list. This is NOT a formal Halal certification — Muslims with stricter requirements should consult their own scholars, and note the open question above about the exact biological source of the Sodium DNA ingredient.

Vegan:* Self-assessed by Adilsons based on available INCI data, and the brand markets this specifically as containing "Vegan PDRN." We could not independently confirm the biological source of the Sodium DNA ingredient beyond the brand's own claim, so treat "vegan" here as a brand assertion we have not separately verified, not a formal Vegan Society certification.

Cruelty-Free: Dear, Klairs is listed by name on PETA's own cruelty-free company database, cross-checked via multiple independent cruelty-free trackers — a stronger status than a self-assessment, though our direct read of PETA's live page was blocked by network access at research time. The brand does not sell through mainland China physical retail.

Microplastic-Free: Yes — no polyethylene or other flagged microplastic polymers detected in the retrieved INCI.

MFDS classification: not confirmed for this SKU. No public functional-cosmetic registration record was found.

Evidence confidence: Medium for the Niacinamide and Vitamin C brightening/antioxidant claims (well-studied ingredient classes generally); Low-to-Medium for the pore-tightening, PDRN, and peptide-firmness claims, which are plausible but not independently verified for this exact SKU.

*Brand claims not independently verified against a disclosed testing protocol for this exact product.

Fungal Acne Safety: FA-Conditional. Polyglyceryl-10 Laurate and Polyglyceryl-4 Laurate, present as emulsifiers, appear on some conservative fungal-acne-safe reference lists as moderate-risk polyglycerol esters — generally lower risk than straight fatty-acid esters, but worth a patch test if you are strongly fungal-acne-prone.

Assessment: Low-to-Medium. The Carbomer/acrylate thickeners can interact with other gel-textured products to cause mild balling if layered without enough absorption time. Wait 60 seconds between this and any other gel serum, and pat rather than rub.

Fresh color should be clear to very pale; a shift to a distinct yellow, orange, or brown tint signals the Vitamin C complex has oxidized and lost potency — this is a genuine spoilage sign for Vitamin C serums, not just cosmetic.

Storage: keep away from direct sunlight and heat, and close the cap fully after each use to limit air exposure, which accelerates Vitamin C oxidation faster than almost any other storage factor.

Patch test on the inner forearm for 24 hours, then behind the ear for another 24 hours, before applying to the full face — this matters more than usual here given the multi-active Vitamin C/peptide load.

72-hour barrier reset (if you react): stop all actives. For 72 hours use only a gentle cleanser and a plain moisturizer, plus mineral SPF outdoors. 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 and discontinue use.

1. Layering this with a separate strong Vitamin C or retinol product in the same routine. 2. Leaving the cap loose or off between uses, accelerating oxidation. 3. Expecting a physical reduction in pore size rather than an optical, hydration-based improvement. 4. Skipping SPF while relying on this for "anti-aging."

Overuse threshold: twice-daily use is the realistic ceiling; using more per application does not meaningfully speed results and simply depletes the bottle faster.

At 2-3 drops per application, a 35 ml bottle yields roughly 200-250 applications.

Used twice daily, that works out to roughly 3-4 months per bottle at the recommended dose; once-daily use extends that to roughly 6-8 months.

Given Vitamin C's oxidation sensitivity, reorder about 2-3 weeks before you expect the bottle to run dry — using an oxidized, near-empty bottle for the sake of "finishing it" provides diminishing benefit.

This product functions as your Vitamin C / skin-quality anchor step, layered after toning and before moisturizer, in both AM and PM.

AM: 1. Cleanser (optional) → 2. Toner → 3. Vitamin PDRN Bouncy Pore Serum → 4. Moisturizer → 5. Sunscreen. PM: 1. Double cleanse → 2. Toner → 3. Vitamin PDRN Bouncy Pore Serum (on nights you're not running a retinoid/acid) → 4. Moisturizer.

If you also use a prescription retinoid, keep this serum to AM only and the retinoid to PM, or alternate nights if you'd rather use both at night. If your skin looks dull from AC exposure, pair this with an extra hydrating toner layer before applying. If you're fungal-acne-prone, patch test first given the polyglyceryl ester emulsifiers present.

Bundle idea (Brighten + protect): MIXSOON Centella Asiatica Toner → this product → SKIN1004 Centella Probio-Cica Enrich Cream → SKIN1004 Hyalu-Cica Water-Fit Sun Serum (AM only).

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 Vitamin PDRN Bouncy Pore 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 specifically want an Alpha-Arbutin-led brightening serum instead of a Vitamin C/PDRN blend, Beauty of Joseon Glow Deep Serum: Rice + Alpha-Arbutin targets dark spots via a different pigment-inhibition pathway. If you want a simpler, single-focus niacinamide/propolis glow serum, Beauty of Joseon Glow Serum: Propolis + Niacinamide is worth considering, though it does not include the PDRN or peptide-firmness angle this product is built around.

Choose the Vitamin PDRN Bouncy Pore Serum over the Glow Deep Serum (Alpha-Arbutin) if you need: a broader multi-active formula covering pore appearance, elasticity support, and brightening in one step, rather than a single-focus pigment-fading serum.

If your main concern is enlarged pores and overall glow, this product is the better fit. If your main concern is specific, stubborn dark spots, the Alpha-Arbutin-led Glow Deep Serum is more targeted for that single goal.

Don't switch if: you are currently using a separate strong Vitamin C or retinoid product you don't want to reshuffle around a new active lane — consistency beats complexity.

This product's PRIMARY function is: pore-appearance smoothing plus Vitamin C brightening and PDRN/peptide elasticity support. You do NOT need this if you already run a separate Vitamin C serum with unopened/unfinished product — finish that first, since layering two would mean doubling up your Vitamin C lane for no added benefit.

Vitamin C serums oxidize faster than most other actives once opened (typically 3-6 months of real potency); buying a second Vitamin C product while one is still fresh means one will likely oxidize before use.

Stacking assessment: No Benefit if you already run a separate strong Vitamin C serum (same lane, redundant). Marginal Benefit alongside a plain niacinamide-only serum (overlapping tone-support, different additional peptide/PDRN angle here). Significant Benefit if your routine currently has no Vitamin C or pore-focused step at all.

Assessment: Suitable, with standard precaution. This formula is fragrance-free with a minimal glycol-based preservative system, which generally favors treatment-sensitized skin, and none of its named actives (Vitamin C forms, niacinamide, Sodium DNA, the peptide trio) are commonly flagged oncology-contraindicated ingredients the way retinoids or strong acids are.

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

Quick checks for this SKU: confirm the batch code uses a clean, fixed-width font (Klairs' most-counterfeited item, the Supple Preparation Toner, has seen fakes with blurred batch-code characters); confirm the serum is clear/pale on arrival, not yellow or brown, which would indicate pre-oxidized or aged stock.

Brand Name: Dear, Klairs. Parent Company: Wishcompany Inc. Founded: acquired by Wishcompany in 2012. Headquarters: Seoul, South Korea.

Klairs built its identity around "simple but enough" formulation — minimal ingredient lists, sensitive-skin-first testing claims, and fragrance-free or low-fragrance formulas across most of its range. The brand is cruelty-free (listed by name on PETA's own cruelty-free company database) though not certified vegan across its full catalog, and it does not maintain mainland China physical retail distribution.

Retailer and review-site copy (including dermapproved.com) consistently describes this serum as lightweight and non-sticky despite its long active list, with users reporting plumper, smoother-looking skin and reduced pore visibility over consistent use; one review specifically noted results on pigmentation "are not instant and require consistency." We also saw a reference to an aggregated rating around 4.3 out of roughly 280 ratings, but could not trace this to one specific, independently verifiable platform, so we are flagging it as directional rather than a confirmed statistic.

No dedicated Reddit (r/AsianBeauty, r/SkincareAddiction) thread specific to this exact SKU was found at the time of writing — treat the above as retailer/review-site sourced rather than a broad independent community sample.

Will this actually shrink my pores? No — pore size is structural. This serum plumps surrounding skin so pores look smaller, which is a real optical effect but not a physical change.

What is "vegan PDRN"? It refers to the Sodium DNA ingredient the brand markets as a plant/fermentation-based alternative to traditional salmon-derived PDRN — we could not independently confirm the exact biological source beyond the brand's own claim.

Can I use this with my Vitamin C serum from another brand? No — this product already contains a 5-form Vitamin C complex including pure Ascorbic Acid, so it occupies your Vitamin C lane for the day. Use one or the other, not both, in the same routine.

Does it work with retinol? Yes, but not layered in the same session — use this AM and your retinoid PM, or alternate nights.

Is it fragrance-free? Yes, based on the INCI we retrieved — no Parfum/Fragrance ingredient is listed.

PDRN

Polydeoxyribonucleotide — a DNA-fragment ingredient marketed for skin-conditioning support; the cosmetic (topical) version is chemically and functionally different from medical/injectable PDRN.

Sodium DNA

The INCI name for the DNA-fragment salt used as the "PDRN" ingredient in this and similar Korean cosmetic formulas.

PIH vs PIE

PIH (post-inflammatory hyperpigmentation) is brown/dark marks from excess melanin; PIE (post-inflammatory erythema) is red/pink marks from damaged capillaries — they respond to different ingredients.

Active Lane

A category of strong active (Vitamin C, retinoid, acid exfoliant, BPO) that should generally not be doubled up with another product in the same lane in one routine.

PAO

Period-After-Opening — the number of months a product remains good for once opened, shown as a jar icon with a number on the packaging.

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

Best for: anyone wanting one multi-active serum that addresses pore appearance, dullness, and early elasticity support without a heavy texture — a strong fit for combination/oily skin in Mauritius humidity.

Key benefits: broad, genuinely multi-functional active list (Vitamin C, niacinamide, PDRN, peptides); fragrance- and alcohol-free; lightweight, fast-absorbing texture.

Keep in mind: individual active concentrations are not brand-disclosed, it occupies the Vitamin C active lane (don't double up with another strong Vitamin C or layer same-night with retinoids/BPO), and the "vegan PDRN" sourcing claim is brand-stated, not independently confirmed by us.
