Obagi Professional-C 20% (travel size)

Obagi's bestselling, highest-concentration daily Vitamin C serum. Formulated with 20% L-Ascorbic Acid and Sodium Hyaluronate, this fast-absorbing antioxidant serum brightens and evens skin tone, reduces the appearance of dark spots, strengthens your skin's antioxidant defenses, and softens the look of fine lines and wrinkles — all for a supercharged, hydrated glow and more youthful-looking skin.

Beyond brightening, the powerful antioxidant formula fortifies your skin's barrier and helps neutralize free radicals, defending against oxidative stress from UV, pollution, and even blue light and infrared radiation that trigger early signs of aging. The added hyaluronic acid binds moisture to the skin, so it never feels drying or greasy.

Clinically loved results: 91% of users reported skin appeared brighter and more hydrated. An award-winner named Allure's Best Antioxidant Facial Serum and Oprah Daily's Dermatologist Favorite Vitamin-C Serum in 2025.
