Vitamin C is a potent antioxidant that can neutralize free radicals, such as those found in environmental pollutants and after exposure to ultraviolet radiation. A vitamin C serum can even out skin tone; diminish dark spots, reduce the appearance of fine lines and wrinkles and brighten the skin. Consider adding this multi-functional product to your skin care regimen.
There are various forms of vitamin C, such as L-ascorbic acid (a pure form of Vitamin C), ascorbyl glucoside (water-soluble derivative) magnesium ascorbyl Phosphate (water-soluble derivative) and ascorbyl tetraisopalmitate (oil-soluble derivative). Obagi Medical Professional-C Serums and Microdermabrasion Polish + Mask contains L-ascorbic acid, a form of Vitamin C that is more bioavailable than others, meaning that it is easier for the skin to absorb.
The Pro-C Serum comes in 3 different strengths, 10%, 15% and 20%, for different skin types. Pro-C Serum 10% is a concentrated formula recommended for dry, irritated or sensitive skin, while Pro-C Serum 15% is a high-performance serum developed for most skin types and Pro-C Serum 20% is the highest concentrated serum best suited for normal to oily skin.
It should be used after cleansing, exfoliating (optional) and toning the skin and before makeup and sunscreen application. Apply five to seven drops to the face, neck and chest using fingertips. If using retinol in your skincare regimen, apply vitamin C in the morning and retinol at night. Otherwise, the serums can be applied both morning and at night.
The shelf life of L-ascorbic acid is typically three to four months after opening, but can be shorter if exposed to light, air or heat for long periods of time. Keep the container securely closed when not in use. Store Obagi Professional-C Serum in a cool, dark area, such as a refrigerator (not freezer) to help prolong its shelf life.
