Key ingredients
These are the ingredients KSECRET highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: confirmed fragrance-free.
| 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. |
| 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. |
| Lactobacillus Ferment | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Sphingomonas Ferment Extract | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Prunus Salicina Fruit Extract | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
