I was quoted by Allure as a dermatologist and topic expert for their guide to Korean vitamin C serums.
I shared perspective on what makes a vitamin C formula effective, including the differences between pure L-ascorbic acid and vitamin C derivatives, and why formulation and tolerability matter just as much as the percentage on the label.
The article also explores how Korean vitamin C products often pair antioxidants with hydrating and barrier-supportive ingredients, with an emphasis on achieving brightening benefits while minimizing irritation.
