What are amino acids?
Amino acids are important components of various proteins , which play many roles and functions in the body's vital activities. In addition, amino acids also synthesize hormones and neurotransmitters necessary to support biochemical processes in the body .
Amino acids combine together in certain sequences in different bonds to form molecules that differ in both composition and properties. Thus, the nutritional value of protein is determined based on the relationship between the quantity and quality of the different amino acids that make up that protein.
Benefits of amino acids for skin
Amino acids play an important role in skin health. Here are some of the key benefits of amino acids for skin.
- Increase collagen and elastin production: Amino acids, especially glycine, proline and lysine, are essential for the synthesis of collagen and elastin. These proteins provide structure, elasticity and firmness to the skin. Decreased collagen and elastin production is a major factor in aging, eating foods rich in these amino acids can help keep skin looking youthful and fresh.
- Wound healing: Amino acids promote the growth and proliferation of skin cells, supporting the healing process. They also contribute to the formation of new tissue, helping wounds heal quickly and reducing scarring.
- Moisturizes the skin: Amino acids act as humectants, attracting and retaining water in the outer layers of the skin. By enhancing water absorption, amino acids work with other moisturizing ingredients, such as hyaluronic acid, to help the skin retain moisture, resulting in smooth, healthy skin that is less prone to dryness and wrinkles.
- Protects skin from UV rays: Certain amino acids, such as tyrosine, have antioxidant properties that may help protect skin from damage caused by harmful UV rays.
- Anti-inflammatory: Certain amino acids, such as arginine and glutamine, have anti-inflammatory properties, and they can also help soothe eczema, psoriasis, and acne, which are often associated with inflammation.
