| Ingredient | What it is | What it does for skin |
|---|---|---|
| Tranexamic acid | A synthetic amino-acid derivative used medically to reduce bleeding and in skincare for uneven tone. | Used in cosmetics for brightening and to help fade the look of dark spots; results at skincare strengths are modest and build slowly. |
| 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. |
| Glutathione | An antioxidant naturally produced by the body, also used topically in some brightening formulas. | Helps neutralize free radicals and is marketed for brightening, though topical absorption and efficacy are less established than oral or injectable use. |
| 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. |
| Centella asiatica extract | A plant extract, also called Cica or tiger grass, long used in traditional medicine for wound healing. | Calms redness and irritation and supports the skin barrier; some preclinical and limited clinical research suggests it may also support collagen production, though more rigorous long-term studies are still needed to confirm this. |
| 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. |
