L-Carnosine is a dipeptide composed of the amino acids beta-alanine and histidine. It is used in cosmetics for its antioxidant and anti-aging properties. L-Carnosine offers several benefits for the skin, making it a popular ingredient in skincare products. Here are the cosmetic functions and applications of L-Carnosine:

1. Antioxidant Protection: L-Carnosine acts as an antioxidant, helping to neutralize free radicals that can cause oxidative stress and damage to the skin. By protecting the skin from environmental aggressors, it helps maintain skin health and prevent premature aging.

2. Anti-Glycation: Glycation is a process in which sugar molecules attach to proteins in the skin, leading to the formation of advanced glycation end products (AGEs). AGEs can contribute to skin aging, including the formation of wrinkles and loss of elasticity. L-Carnosine has been shown to help inhibit glycation, thereby reducing its negative effects on the skin.

3. Skin Repair: L-Carnosine has been suggested to support the skin's natural repair processes, helping to maintain skin integrity and barrier function.

1. Anti-Aging Formulations: L-Carnosine is commonly found in anti-aging skincare products, such as creams, serums, and lotions, aimed at reducing the appearance of fine lines, wrinkles, and other signs of aging.

2. Moisturizers: L-Carnosine can be included in moisturizers to provide antioxidant benefits and support skin health.

3. Serums: It is used in various serums targeting specific skin concerns, including anti-aging.

4. Eye Creams: L-Carnosine can be found in eye creams to address concerns like fine lines and promote a more youthful appearance around the delicate eye area.
