Key ingredients
These are the ingredients ONCLO highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: this formula contains added fragrance.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| PDRN (sodium DNA) | Polydeoxyribonucleotide, DNA fragments commonly derived from salmon, used in Korean regenerative skincare. | Studied for supporting collagen production and tissue repair; a newer ingredient category with a shorter independent track record than long-established actives. |
| Adenosine | A compound naturally present in skin cells, used in skincare as an anti-aging active. | Recognized by South Korea's MFDS as a functional anti-wrinkle ingredient at 0.04% concentration, based on clinical studies showing measurable fine-line improvement; a real but modest effect, not a retinoid substitute. |
| Sodium hyaluronate | The salt form of hyaluronic acid, commonly used for its water solubility and stability in formulas; molecular weight varies by product rather than being uniformly smaller. | Draws and holds moisture the same way hyaluronic acid does; how easily it absorbs depends on the specific molecular weight used, which formulas don't always disclose. |
| Allantoin | A soothing compound, naturally occurring in some plants and also made synthetically. | Calms irritation and supports skin healing, often paired with other barrier-focused ingredients. |
| Grapefruit peel oil | A cold-pressed essential oil from grapefruit peel, added to formulas primarily for scent. | Provides a citrus scent; contributes little functional skincare benefit beyond fragrance.Note: A citrus essential oil that can increase skin's sensitivity to UV light. Daytime sun exposure on treated skin carries some phototoxicity risk, and it is a source of the flagged fragrance allergens limonene and linalool. |
| Bergamot peel oil | A cold-pressed essential oil from bergamot orange peel, added to formulas for scent. | Provides a citrus-floral scent; contributes no meaningful active skincare function beyond fragrance.Note: One of the most strongly phototoxic essential oils used in cosmetics, due to its bergapten content, unless a bergapten-reduced (FCF) version is used, which brands do not always specify. Daytime sun exposure on treated skin carries a real risk of burns or dark patches. Also a source of the flagged allergens limonene and linalool. |
| Limonene | A naturally occurring compound found in citrus peel oils, commonly present wherever a formula contains citrus essential oils or extracts. | Contributes a citrus scent; has no independent skincare function beyond fragrance.Note: One of the EU/UK's officially recognized fragrance allergens, required to be individually declared above a labeling threshold. Oxidizes on air exposure into more sensitizing byproducts over a product's shelf life. |
| Linalool | A naturally occurring compound found in many essential oils, including lavender, bergamot, and citrus peels, commonly present wherever a formula contains those oils. | Contributes a floral scent; has no independent skincare function beyond fragrance.Note: One of the EU/UK's officially recognized fragrance allergens, required to be individually declared above a labeling threshold. Oxidizes on air exposure into more sensitizing byproducts over a product's shelf life. |
