Amino acids have specific role in skincare. They can maintain the skin’s hydration, texture, resilience, and the overall supple and healthy appearance. They are naturally present in the human skin.
The primary benefit of the amino acids is that they can maintain skin’s smoothness and hydration, something they also do when applied via skincare products. Some of them also work as antioxidants and when applied topically, they can help strengthen the skin’s natural defense system, by making it less likely to show signs of aging.
Although all the amino acids play a role in creating and maintaining smooth, healthy, younger-looking skin, a few of them have more specialized roles:
- Arginine can repair skin damage
- Histidine can soothe skin
- Methionine can neutralize damaging substances
- Lysine can firm skin’s surface
- Proline, leucine, and glycine can diminish fine lines and wrinkles
All amino acids included in the skincare products can work in combination with other ingredients such as: glycerin, ceramides, many types of peptides, hyaluronic acid, etc. The amino acids can work particularly well with peptides - ingredients that can significantly increase the hydration of the skin and can significantly reduce the signs of aging.
They are such versatile ingredients that when applied topically, can improve all skin types, and can benefit all ages, especially the ones with fine lines and premature wrinkles.
