COS DE BAHA Peptide Serum 30ml

Values: 100% Genuine (Adilsons policy) · FA-Safe · Fragrance-Free (no Parfum/Fragrance in the confirmed INCI, though several botanical extracts are present — see Allergens section) · Vegan-Friendly* / Cruelty-Free* (brand-stated).

Pros: no acid/retinol irritation risk, gentle enough for daily AM+PM use, hydrating base, pairs with any other active. Caveats: peptide %concentrations are not publicly disclosed by the brand; Adilsons' own prior product copy for this SKU referenced "concentrated Chamomile Extract" that we could not independently confirm in the researched INCI list — we are not repeating that specific claim until verified; community reviews are genuinely mixed on whether visible line-softening occurs.

Classification: GREEN. Peptides and adenosine are non-exfoliating, non-irritating ingredient classes with no established age restriction. That said, this is an anti-aging-positioned product with no functional benefit for pre-collagen-loss skin — it is not marketed toward and offers nothing for teens or tweens, who should focus on basic cleansing/hydration/SPF instead.

Bedside-compatible: yes. Requires rinsing: no. Requires precise dosage: no. Wait time: minimal. This is a low-friction, low-risk product to keep in a bare-bones routine on low-energy days since it carries no purge or irritation risk to manage.

Step 1 (When): AM and PM, after cleansing. Step 2 (How much): 2-3 drops. Step 3 (How): pat in, wait 30-60 seconds before 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. Cleanse. 2. Toner/essence (optional). 3. COS DE BAHA Peptide Serum. 4. Moisturizer. 5. Sunscreen SPF50+ PA++++ (peptides do not provide UV protection — collagen-supporting benefits are undone by unprotected UV exposure). In humid mornings this serum's hyaluronate content benefits from the ambient moisture the same way any humectant does.

1. Double cleanse if wearing SPF/makeup. 2. Toner/essence (optional). 3. COS DE BAHA Peptide Serum. 4. Any acid/retinol you run that night (apply peptides first if sensitive, or peptides after if you prefer sequencing acids first — see Conflict note below). 5. Moisturizer. This product fits into Recovery nights of a 4-night skin-cycling protocol as a gentle, non-active-lane addition.

Technique: pat/press, do not rub — some peptide bonds can be disrupted by aggressive friction over time. Skin state: slightly damp is fine. Wait time: 30-60 seconds before moisturizer. Hands deliver 100% of product; cotton pads absorb approximately 30-40% — use hands.

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, 10-15 minutes before sunscreen if going outdoors. Amount defaults: toner/essence 5-8 drops, serum 2-3 drops or 1 pump, eye product half a rice grain, gel moisturizer 1-1.5 peas, cream 1-2 peas, occlusive rice-grain to pea, sunscreen 2-finger rule for face. 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). 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 (optional). 10. Oil-control lane (optional). 11. Peptide/repair lane — this product's role. 12. Eye product (optional). 13. Moisturizer. 14. Optional sealing layer if dry/AC. 15. Sunscreen SPF50+ PA++++ (non-negotiable). 16. Lip SPF (optional).

PM Maximum Stack: 1. Micellar pre-cleanse (optional). 2. Oil cleanser if wearing SPF/makeup. 3. Water cleanser. 4. pH-prep toner (optional). 5. Hydrating toner layers (optional). 6. Essence (optional). 7. Soothing serum (optional). 8. Anchor active of the night, if any (retinol/acid — different lane). 9.

Lip sleeping mask (optional). Do not layer retinoids with AHA/BHA in the same night; keep one lane per night.

Lane strictness: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration/peptides can always accompany.

Tier: light fluid serum. Layering rule: apply after watery toners/essences, before moisturizer. Phase: water-phase, no known pilling triggers among the confirmed ingredients.

Fine expression lines: Argireline (Acetyl Hexapeptide-8) is studied as reducing the muscle-contraction signaling associated with expression lines, though evidence is mostly in-vitro/mechanistic rather than large-scale clinical trials. Early collagen support: Matrixyl 3000's Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 are studied for signaling collagen/elastin-supporting activity. Secondary benefit: hydration from Sodium Hyaluronate. What it cannot do: it cannot replace the mechanical effect of prescription neuromodulators (like injected botulinum toxin) or dermal fillers, and it cannot reverse deep, established static wrinkles.

Sunscreen (mandatory AM, protects any collagen-support gains): primary — Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+; alternatives — SKIN1004 Centella Hyalu-Cica Water-Fit Sun Serum, Anua Heartleaf Silky Moisture SunCream, ROUND LAB Birch Juice Tone-Up Sunscreen.

Moisturizer to seal: primary — Dr.Althea 147 Barrier Cream; alternatives — Beauty of Joseon Dynasty Cream, Anua Birch Moisture Boosting Cream, SKIN1004 Centella Probio-Cica Enrich Cream.

Active pairing: compatible alongside your COS DE BAHA Retinol Serum on a different night, or your Vitamin C Serum in AM (apply peptides after Vitamin C, waiting 10-15 minutes, since copper-sensitive peptide chemistry can be affected by very low pH).

Water-Permeable (wudu-compatible). This is a light, non-occlusive, non-film-forming serum. 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: "Argireline works exactly like Botox." REALITY: Argireline is a topical peptide that may modestly reduce the signaling associated with expression-line formation over weeks of use; it does not mechanically paralyze muscle the way an injected neuromodulator does, and the two are not equivalent in strength or speed.

MYTH: "More peptide serum, faster results." REALITY: peptides work as slow signaling molecules — over-applying does not accelerate the timeline and can just waste product.

Mauritius tap water hardness varies by region; a hard-water film after cleansing can feel like this serum "isn't absorbing," when a pH-balancing toner beforehand is usually the real fix.

*Argireline's line-softening evidence is largely industry/in-vitro rather than large independent human trials; treat as Emerging.

Full INCI list: Aloe Barbadensis Leaf Extract, Glycerin, Propanediol, 1,2-Hexanediol, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Acetyl Hexapeptide-8, Sodium Hyaluronate, Beta-Glucan, Adenosine, Butylene Glycol, Rosa Damascena Extract, Lavandula Angustifolia Flower Extract, Camellia Sinensis Leaf Extract, Melissa Officinalis Leaf Extract, Artemisia Vulgaris Extract. [--- Estimated 1% Line ---] Estimated after Adenosine — the peptides, adenosine, and everything following are typically dosed under 1% industry-wide, though this is an estimate, not a brand-confirmed cutoff.

Note on a prior claim: Adilsons' own previous copy for this SKU referenced "concentrated Chamomile Extract" as an active. Chamomilla/Matricaria does not appear in the INCI list we could verify via WebSearch summaries in this pass — we are flagging this as an open discrepancy rather than repeating or silently dropping the claim; it is possible the ingredient exists under a different name or the researched list is incomplete.

Preservative system: 1,2-Hexanediol (multifunctional preservative-booster/solvent).

Fragrance status: Fragrance-Free (no Parfum/Fragrance listed). Scent: likely a faint herbal note from the rose/lavender/green tea/melissa/mugwort extracts present in the formula, though no fragrance oil is declared. Intensity: estimated 1 out of 5. EU 26 allergen screen: none of the 26 named allergen molecules were detected as standalone listings in the confirmed INCI, though the botanical extracts present (especially Rose and Lavender) can carry trace natural allergens even when declared as a plant extract rather than an essential oil — patch test if you are fragrance-extract-reactive. Alcohol disclosure: Alcohol-Free.

Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared list. This is NOT a formal Halal certification.

Vegan: *Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected (the peptides here are lab-synthesized, not animal-extracted). This is NOT a formal vegan certification.

Cruelty-Free: *Brand-stated policy, not independently certified by Leaping Bunny, PETA, or equivalent audit.

Microplastic-Free: Yes.

MFDS Classification: not publicly confirmed. Clinical evidence: Matrixyl 3000's component peptides have moderate published industry evidence; Argireline's line-softening claims lean more Emerging/in-vitro. Evidence confidence: Medium for the peptide complex overall, Low-Medium specifically for visible line-softening claims from Argireline.

Fungal Acne Safety: FA-Safe. No documented Malassezia-feeding esters among the confirmed ingredients.

Assessment: Low. No known pilling triggers among the confirmed ingredients; reduce layers if pilling occurs when stacked with heavier silicone-based products.

Fresh appearance: clear to very pale straw. Storage: keep out of direct sun and away from prolonged heat above roughly 30°C — peptides can lose activity with heat exposure over time even without visible spoilage. Spoilage signs: off smell, cloudiness, or separation. When in doubt, discard.

Patch test: inner forearm for 24 hours, then behind the ear for 24 hours, then begin facial use. If adverse reaction: STOP ALL ACTIVES. For 72 hours, use ONLY gentle cleanser plus plain moisturizer plus mineral SPF. After 72 hours, reintroduce ONE product per 14 days. Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care.

1. Expecting Botox-level results from a topical peptide. 2. Judging results before 8-16 weeks. 3. Skipping daily SPF, which undermines any collagen-support gains. 4. Storing the bottle in a hot bathroom, degrading peptide activity faster. 5. Over-applying, assuming more product speeds up a slow-acting ingredient class.

Volume: 30ml. Amount per use: 2-3 drops (~0.4-0.6ml). Approximate uses per container: roughly 50-70 applications. Lifespan: at twice-daily use, approximately 4-5 weeks. Reorder roughly 2 weeks before you expect to run out, since consistency matters for a slow-acting active like this.

This serum's job is gentle, non-acid anti-aging support — it sits in the peptide/repair lane of the AM/PM stack, alongside (not instead of) SPF as the actual biggest anti-aging lever. AM: cleanse → toner (optional) → Peptide Serum → moisturizer → sunscreen. PM: cleanse → toner (optional) → Peptide Serum → any other active on its own night → moisturizer.

If you already use a retinol: this peptide serum can run alongside it on non-conflicting nights or in the AM instead. If your goal is faster visible change: a retinol or retinol-combo product will likely outperform peptides alone on timeline — consider COS DE BAHA Retinol Serum as a complementary, different-mechanism addition rather than a replacement.

After purchasing, you will receive our skincare education email series covering this product in depth. The recommendations above are based on formulation synergy with COS DE BAHA 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.

We do not currently carry another dedicated peptide-complex serum to compare this against directly — this category is under sourcing review beyond this one SKU. If your priority is faster, more clinically-established anti-aging results rather than a gentle daily peptide step, see COS DE BAHA Retinol Serum instead, understanding that comes with a different risk/irritation profile.

This product's PRIMARY function is: gentle peptide-driven anti-aging support plus light hydration. You do NOT need this if you already own another peptide serum or cream with a similar Matrixyl/Argireline/Adenosine profile — finish that one first. Stacking assessment: No Benefit if run alongside another peptide-forward product (redundant mechanism); Significant Benefit if your current routine has no anti-aging step beyond SPF.

COS DE BAHA positions itself as a value/high-potency actives brand, selling clearly-labeled single- and combo-active serums at accessible prices relative to prestige K-beauty actives brands. This peptide serum represents its gentler, non-acid anti-aging entry alongside the brand's stronger retinol and acid lines.

Independent review-aggregator sources surfaced a mixed picture for this specific product: one reviewer on a second bottle reported no visible change in fine lines and would not repurchase, though also reported no breakouts or irritation; another reviewer described it as economical and effective with a pleasant finish. These are presented as anecdotal, single-source accounts from review aggregators rather than verified Reddit/Amazon threads, and common themes beyond this were not found in our research.

Does this replace Botox? No — it is a topical peptide serum, not an injectable; effects are gradual and cosmetic rather than mechanically paralytic.

How long until I see results? Realistically 8-16 weeks of consistent use, if you respond to it at all — peptide response varies by individual.

Can I use this with retinol? Yes, no active-lane conflict; use on the same or different nights as preferred.

Does it contain Chamomile? We could not confirm a chamomile ingredient in the INCI list we verified this pass, despite it appearing in an earlier version of this product's own copy — treat that specific claim as unconfirmed for now.

Is it fragranced? No added Fragrance/Parfum, though it contains several botanical extracts that carry a mild natural scent.

Best for: anyone wanting a gentle, non-irritating anti-aging step or a peptide layer to run alongside stronger actives on other nights. Key benefits: no acid/retinol irritation risk, hydrating base, daily AM+PM use, well-documented peptide complex. Keep in mind: results are slow (8-16 weeks) and individual, peptide %s are undisclosed, and independent reviews on visible results are genuinely mixed.

Assessment: Suitable for most treatment-sensitized skin, based on the confirmed formula being fragrance-free, retinoid-free, and minimal-preservative (1,2-Hexanediol only). The botanical extracts present are mild but worth flagging to your care team given generally heightened sensitivity during treatment. Consult your oncology care team before introducing any new skincare products during treatment.
