Dr. Barbara Sturm’s NIGHT SERUM has been specially developed to support the skin’s nightly regeneration phase. One of the key ingredients, Cotton Thistle Extract supports and stimulates collagen and regenerates the skin barrier, thus counteracting dry and stressed skin. The anti-oxidant properties of Senna Alata Extract supports the skin’s own protection against UV-induced damage, while an extract of Poria Cocos helps reduce the appearance of skin irritation whilst toning and calming the skin. Beta-Glucan calms the skin and reduces redness whilst the potent plant extract Purslane, activates the skin’s own antioxidant system and protects the skin from attacks by free radicals. The active ingredient concentrate uses the night-time to penetrate into the skin and supplies it with Hyaluronic Acid. Plankton Extract helps to reduce the appearance of wrinkles and instantly makes the complexion appear more even. Overall, the skin looks youthfully smoother and fresher after waking up in the morning.
