Cotton Thistle Extract counteracts dryness and stressed skin. The anti-oxidative and other properties of Senna Alata Extract aids the skin’s own protection against UV-induced damage, while a compound deployed in Chinese medicine, Poria Cocos, works to balance the neuropeptides responsible for irritation and provides astringent, toning and calming properties. Beta-Glucan calms the skin and reduces redness while antioxidant and anti-aging powerhouse Purslane provides both oxidation and irritation protection. Dr. Sturm’s proprietary formulation of high dose, molecularly balanced Hyaluronic Acid works throughout the night to replenish moisture reservoirs at multiple skin layers by binding up to 1,000 times its weight in water. After using the NIGHT SERUM, wake with fresher, smoother and healthier-looking skin.
