Targeting post-acne hyperpigmentation and texture, Oubo's face serums that help with acne scars combine proven actives in a gentle formula. The hero serum features 2% alpha-arbutin (naturally derived from bearberry) to inhibit melanin production, 1% mandelic acid (a gentle AHA) for exfoliation, and niacinamide to even skin tone. Alpha-arbutin is 10 times more effective than kojic acid in lightening scars, while mandelic acid's large molecular size ensures gentle exfoliation, suitable for post-acne skin. Hyaluronic acid and aloe vera keep the skin hydrated during the scar-fading process. Clinical trials show a 42% reduction in acne scar pigmentation after 12 weeks, with 89% of users reporting smoother skin texture. Free from benzoyl peroxide and harsh acids, this serum is gentle enough for daily use, even on sensitive, acne-prone skin.
