Obagi Professional-C Serum 20% is formulated for mature, sun-damaged skins that are coarse, leathery and deeply lined and it is also indicated for oily skins. It is a highly concentrated, high-performance serum that improves signs of skin ageing by stimulating collagen synthesis and visibly helping to improve pigmentation and brightens the skin.
Key ingredients include L-Ascorbic Acid 20% which is Vitamin C in its purest form. It is also formulated for oily skins as it is the highest percentage of L-Ascorbic Acid which has an anti-bacterial effect on the skin and that helps to targets breakouts and prevent them from reoccurring. It has antioxidant protection and has superior absorption into the epidermis and deep penetration into the dermal layer due to its low pH which enables it to stay stable for a longer period of time in these layers. It does not leave an oily layer on the skin due to its deep penetration. Avoid direct contact with the mucous membranes. It also enhances UV protection and will not cause any irritation on the skin.
