Key ingredients
These are the ingredients COSRX 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 |
|---|---|---|
| Madecassoside | One of centella asiatica's key active compounds, often isolated and purified. | A soothing, antioxidant compound studied for calming sensitive and reactive skin and supporting barrier repair. |
| 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. |
| 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. |
| Panthenol | Pro-vitamin B5, which converts to pantothenic acid once absorbed into skin. | Hydrates as a humectant, supports wound healing, and has anti-inflammatory, soothing effects on irritated skin. |
| 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. |
| Glycerin | A humectant naturally present in skin, one of the most well-established moisturizing ingredients. | Draws water into the skin's outer layer, helping maintain hydration and support the barrier. |
