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 anti-oxidant 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.
