Key ingredients
These are the ingredients K-Secret highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.

| Ingredient | What it is | What it does for skin |
|---|---|---|
| Bakuchiol | A plant-derived compound from babchi seeds, often described as a gentler alternative to retinol. | Small studies suggest it can improve the look of fine lines and uneven tone over time with less irritation than retinol, although it is not chemically a retinoid.Note: Less studied than retinol. Patch test first if your skin is sensitive. |
| 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. |
| Ginseng extract | An extract of ginseng, widely used in Korean skincare. | Used as an antioxidant and skin-conditioning ingredient; evidence is mostly from small studies. |
| 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. |
| Ethyl ascorbic acid | A stable, water-soluble form of vitamin C (3-O-ethyl ascorbic acid). | An antioxidant used to brighten the look of dark spots and even skin tone; gentler and more stable than pure vitamin C. |
