Shereene Idriss walks through antioxidants beyond vitamin C: Coenzyme Q10 for dull skin, kojic acid for dark spots, vitamin E for irritation, Centella Asiatica for a weakened barrier, vitamin C esters as a gentler option, and glutathione as the master antioxidant for a full skin reset.

Chapters

For dull, tired skin, Coenzyme Q10 energizes and protects collagen. Stubborn dark spots? Kojic acid brightens while fighting oxidative stress. Your skin is feeling tight or irritated? Use vitamin E. But for stressed, reactive skin, Centella Asiatica will strengthen your skin barrier. If you can't tolerate a traditional vitamin C because they can be irritated AF, use a vitamin C ester to support collagen production and brighten your skin. And just like vitamin C is potentially the crown jewel, the master antioxidant for an overall reset for your skin? Glutathione.
