What Professional-C Serum 15% Does

Obagi Professional-C Serum 15% is the middle strength in Obagi's vitamin C serum range and suits most skin types. It is a strong choice if you want visible brightening but would rather not jump straight to the 20%.

This Obagi vitamin C serum delivers 15% L-ascorbic acid, the purest form of vitamin C. It helps brighten and even out skin tone, strengthens the skin's antioxidant defences and improves the look of fine lines and wrinkles. Obagi's own testing found most users said their skin looked brighter and more hydrated. Use it as your daily antioxidant step under moisturiser and SPF for a supercharged glow. Sensitive or new to vitamin C? Try the 10%. Oily skin used to vitamin C? Consider the 20%.
