A dermatologist favourite, these serums offers the highest concentration of L-ascorbic acid and are said to deliver significantly better penetration into the epidermis and dermis than most vitamin C serums. Obagi professional C serums contain a powerful punch of the powerhouse antioxidant that helps reduce skin inflammation, irregular pigmentation, and promote healthy collagen production. Visible signs of ageing skin, fine lines and wrinkles are caused by tiny molecules known as ‘free radicals’. They are formed during normal skin function but dramatically increase during exposure to the sun, air pollution and other environmental assaults. The powerful anti-oxidant action of Obagi professional-C serums neutralises free radicals before they can cause damage to the skin’s epidermal cells. It penetrates to the epidermis ands dermis to protect skin cells and stimulate collagen production. The result: Brighter and firmer skin, fewer fine lines and wrinkles and a more even skin tone.
