Obagi Professional-C 15% Serum 30ml

15% L-ascorbic acid antioxidant serum for daily defence and brightness. It suits most skin types, and it is the strength we recommend most often, because it is high enough to do real work without the irritation the 20% can cause in reactive skin.

Apply four to five drops to clean, dry skin each morning, then moisturiser and sunscreen. The serum reduces the damage sunlight does, the sunscreen stops it, and neither replaces the other. Give it eight to twelve weeks. If you are already comfortable on the 10% and want more, this is the sensible next step rather than jumping to 20%. Keep the bottle closed and away from light.
