Glutathione addresses hyperpigmentation through three primary mechanisms:
The tripeptide molecule achieves visible reductions in discoloration through targeted cellular actions:
- Tyrosinase Inhibition: It directly and indirectly halts the activity of tyrosinase, which is the rate-limiting enzyme required for melanin biosynthesis.
- Melanin Shifting: It encourages melanogenesis to favor the production of lighter, yellow-red pigments (pheomelanin) over darker, brown-black pigments (eumelanin).
- Antioxidant Defense: It neutralizes free radicals and oxidative stress caused by UV radiation, which are common triggers for dark spots and melasma
Vitamin C helps with Skin Brightening: By fading existing dark patches, it evens out the overall skin tone and imparts a healthy glow
