Key ingredients
These are the ingredients REJURAN 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. |
| Squalane | A stable, skin-identical oil, usually plant-derived (from olives or sugarcane) in modern formulas. | An emollient that softens skin and helps prevent moisture loss without feeling heavy or greasy. |
| Hydrolyzed DNA | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Ceramide NP | One specific, well-studied type of ceramide used in skincare formulas. | Reinforces the skin barrier and helps it retain moisture, the same core ceramide function. |
| Cholesterol | One of the three core lipids (alongside ceramides and fatty acids) that make up the skin barrier. | Works together with ceramides and fatty acids to reinforce the barrier and reduce moisture loss. |
| Arbutin | A brightening compound derived from plants like bearberry. | Inhibits the enzyme that triggers pigment production, gradually helping fade dark spots; works more slowly than stronger brighteners, generally with less irritation. |
| 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. |
