What it is: A serum with a unique mixture of vitamin C in three skin-friendly forms at a concentration that's easily absorbed, safe and gentle, too. What it does: This serum contains an active ingredient complex that includes oil-soluble vitamin C THD, stabilized, synthetic vitamin C in glucosidic form and an extract from kakadu plum, a fruit that is a potent source of plant-based vitamin C. Together they help reduce signs of uneven pigmentation and improve tone while providing antioxidant protection against environmental stressors for a bright, even glow. This serum also contains zinc, which increases the absorption of vitamin C into the skin. Additionally, vitamin C supports the formation of collagen, which is needed for a firmer and more youthful glow. The Good C contains a concentration of 5% vitamin C that is safe and gentle. Higher concentrations do not remain stable on the skin and can trigger inflammation and damage the skin's barrier function. How to use: Place a pipette-length of serum into the palm of your hand and distribute over your face using gentle tapping motions. Avoid the eye area. Let absorb for one minute before following with additional skin care products. 1 oz.
