Vitamin C Ester 20% Dark Spot Corrective Serum

A high-potency serum featuring a 20% concentration of three forms of vitamin C, alpha-arbutin, and resorcinol to target stubborn dark spots and uneven tone. This is a heavy hitter for hyperpigmentation, utilizing Perricone MD’s proprietary Vitamin C Ester to address photodamage and age spots. It’s a serious treatment for discoloration that hasn't budged with lighter formulas, though the 20% concentration rewards a patient introduction if you're new to high-strength actives.
