The active concentrate HYALURONIC SERUM was specially developed to meet the beauty needs of darker skin tones. Pure Hyaluronic Acid and the complexion refiner Lumicol lend the skin a smoother appearance and create a more even skin tone. Long and short-chain Hyaluronic Acid provides an intensive moisturization boost with an instant refreshing effect, making fine lines disappear tangibly and visibly. Purslane, the anti-aging ingredient that was developed specially by Dr. Sturm, activates the skin's own antioxidant defense system, combats inflammation and protects sensitive cell membranes against free radical attack. In combination with the active ingredient Lumicol, which improves the complexion, it adds radiance to the skin and lends it a more refined and glowing appearance. The serum develops its special moisturizing powers most effectively if it is used as an intensive course of treatment over a period of one to three weeks. How to Use: Squeeze the contents of a pipette into the palm of your hand and smooth over your face. Pat gently into the skin. In 30 seconds, the serum is quickly absorbed by the skin. After the serum has been absorbed, apply the FACE CREAM. The serum is suitable for all skin types.
