Description
Obagi Professional-C Serum 20% is Obagi's highest-concentration vitamin C serum. Used daily, this L-ascorbic acid serum helps minimise the appearance of fine lines and wrinkles and fortifies skin's defences against environmental assaults.
What it does
- Proactively fortifies the skin's defences against environmental assaults
- Encourages skin to rebound from previous visible damage, for an improved appearance of fine lines, wrinkles and uneven skin tone
- Strengthens skin's defence with a powerful antioxidant
Who it suits
The 20% strength suits skin already used to vitamin C that wants Obagi's most concentrated option. If you are new to vitamin C, start with Professional-C 10% or Professional-C 15%. Some people feel a slight tingle, which should lessen with continued use.
