A powerful age-defying serum—with 15% vitamin C, 5% PHAs and hyaluronic acid—for brighter, bouncier skin in 7 days, based on an independent 8-week clinical study on 33 women.This vegan, gluten and cruelty-free serum contains Ole’s highest concentration of vitamin C for daily use. It combines three Ole Glow icons—vitamin C, exfoliating acids and banana powder-inspired pigments—to help improve skin’s elasticity, boost radiance and defend skin against pollution. And, with hyaluronic acid, this multi-acid serum helps reinforce skin’s moisture barrier. Plus, you’ll love this serum’s minimal, naturally derived orange scent (it was rigorously tested for safety, toxicity and allergens).
