This clean, silicone-free, fragrance-free primer preps skin for smooth application while providing a natural barrier against pollution. Its silky texture transforms on contact to a tightening effect: firming skin, refining pores and softening fine lines while leaving skin radiant.Key ingredients:- Hibiscus extract: helps to protect against free-radical damage- Beta-glucan: helps to reduce the appearance of fine lines and wrinkles- Mastic: a resin from a tree that grows on the Greek island of Chios, helping to mattify and refine skin throughout the dayHow to use: Shake well before use. Prep your skin with three to four drops of True Skin Radiant Priming Serum after moisturizer and before makeup. Apply with your fingers as you would a serum and pat into skin. Observe the tightening effect on skin as the primer transforms to a silky soft-to-the-touch finish on dry down.
