INGREDIENT GLOSSARY • Antioxidant
AT A GLANCE
Oil-soluble derivative of vitamin C that penetrates skin deeply to fight free radicals.
Ascorbyl Tetraisopalmitate is a powerful antioxidant and tyrosinase inhibitor, meaning it fades hyperpigmentation. Its oil solubility allows it to penetrate deeper than other popular vitamin C derivatives.
C+C Serum (5%)
Enter ascorbyl tetraisopalmitate (ATIP), a stable yet highly effective derivative of ascorbic acid. Unlike other derivatives, ATIP is oil-soluble. The skin’s outermost barrier is oil-based, so other oil-based ingredients are generally able to penetrate much better than water-soluble ones. That’s definitely the case with ATIP, which has been observed to penetrate both the epidermis and the dermis below it.
Once ATIP is in the skin, your body converts it to ascorbic acid, where it does all the phenomenal things that ascorbic acid does for your skin:
-Fights free radicals to mitigate UV damage
-Stimulates collagen production
-Inhibits excess melanin production, fading hyperpigmentation
