Inhibit melanin production
- ** Arbutin ** : Extracted from bear leaves, it inhibits tyrosinase activity.
- ** Kojic Acid ** : A fungal metabolite that blocks melanin synthesis but may irritate the skin.
- Tranexamic Acid: Inhibits the activation of melanocytes and improves chloasma.
- **SymWhite® 377 (phenethyl resorquinone) ** : A potent tyrosinase inhibitor with high stability.
2. ** Block melanin transfer **
- ** Nicotinamide (Vitamin B3) ** : Reduces the transfer of melanin to the epidermis, while having anti-inflammatory effects and repairing the barrier.
3. Accelerate melanin metabolism
- ** Alpha hydroxy acids (AHA/BHA) ** : Glycolic acid, lactic acid, etc. promote keratin shedding.
- ** Vitamin C and its derivatives ** : Antioxidant, reduces melanin, stimulates collagen synthesis (such as ascorbic acid glucoside, magnesium ascorbic acid phosphate).
4. "Natural Extracts
- ** Glabridin ** : Extracted from licorice root, anti-inflammatory and whitening.
- ** Resveratrol ** : Antioxidant, inhibits ultraviolet damage.
