Vitamin C is a powerful antioxidant which works to protect your skin from free radicals which are generated in your skin during and after exposure to UV light from the sun. In its L-ascorbic acid form, vitamin C can soak through the layers of your skin to offer its beneficial mechanism of action to the deeper layers. Here, its antioxidant properties can have a more pronounced effect in combating the visible signs of ageing, such as fine lines and wrinkles. 

Topical application of vitamin C not only protects your skin from UV related damage and enhanced ageing, it plays a vital role in collagen production in your skin. Collagen is responsible for your skin's firmness and elasticity and so Obagi Professional-C 20% is designed to improve skin’s plumpness and promote a healthy youthful glow.


To enhance the skin-firming effects of L-ascorbic acid, this serum also contains hyaluronic acid. This is a clever molecule that binds to water in your skin and locks it in, preventing dryness and further encouraging a plump and rejuvenated look to your skin.  


Obagi Professional-C Serum 20% works to brighten the appearance of hyperpigmented skin and dark spots, to push a radiant and even skin tone. Not only does this serum improve skin tone, it works to enhance the skin’s texture as well.
