Rated the best glutathione dark spot serum patch for women who've tried serums that didn't work
GLUTATHIONE (MASTER ANTIOXIDANT)
Glutathione inhibits tyrosinase, the enzyme responsible for melanin production. It's the same active ingredient used in dermatology clinics and $200 IV drips. The patch delivers it directly to your dark spot at concentrated levels, not diluted across your entire face.
