The brightening serum that defined the category. Perricone MD‘s Vitamin C Ester 15 uses a fat-soluble form of vitamin C that penetrates the skin more effectively than the standard ascorbic acid formulations most brands use.
What’s in it
Vitamin C ester at 15% concentration, supported by alpha lipoic acid and DMAE — the brand’s signature anti-aging trio.
How it wears
Lightweight serum, applied morning under SPF. Skin reads brighter and more even within 4–6 weeks of consistent use. Wears comfortably under everything you put on top.
The brightening serum that’s earned its decades-long shelf life.
