Two full-size Obagi Professional-C Serum 20% 30ml in one listing. This is Obagi's highest-concentration L-ascorbic acid serum, formulated with hyaluronic acid, and best suited to normal to oily skin looking for brighter, more even-looking tone.
What it does
Professional-C Serum 20% delivers L-ascorbic acid, the form of vitamin C most studied for topical use, at the strongest level in the Professional-C range. Vitamin C is an antioxidant that helps defend skin against environmental stress and supports a brighter, more even-looking complexion over time. Sodium hyaluronate adds a light layer of hydration so the fluid, fast-absorbing texture does not feel drying. Skin looks fresher and more luminous with daily use, and the look of fine lines is softened. Obagi positions the 20% strength for normal to oily skin; the 10% and 15% versions are gentler options for drier or more reactive complexions.
How to use
For each bottle: apply five to seven drops to clean, dry skin every morning, before moisturiser, sunscreen and make-up. Vitamin C can tingle briefly on first use. Wear SPF daily. Patch-test first.
Who it's for
Adults with normal to oily skin who want a high-strength vitamin C and prefer to buy two bottles at once. Not the first choice for very sensitive skin.
