Carnosine
What is Carnosine?
Carnosine is a naturally occurring dipeptide consisting of beta-alanine and L-histidine, found in mammalian muscle and brain tissues. In skincare products, it functions mainly as a skin conditioning agent within anti-aging formulations like serums and creams. Chemically stable and water-soluble, it penetrates skin layers to neutralize free radicals, offering antioxidant defense. It also counters glycation, where sugars bind to proteins like collagen, helping preserve skin structure. Typically produced synthetically for cosmetics to ensure purity, carnosine maintains product efficacy across various pH levels. Its role enhances skin barrier integrity without altering texture, making it suitable for daily use in protective and restorative topicals.
