Arginine is an alpha-amino acid that is a building block for protein synthesis. Arginine is synthesized by our bodies and we get it from meat, eggs and dairy products, as well as some plant sources. As an external agent, arginine has many skin care benefits. Here are some of the main benefits of arginine:

1. Fights free radicals.

Free radicals are everywhere, from the food we eat, the air we breathe, the water we drink, the external environment we are exposed to, and our body's metabolism. They are unstable molecules that can damage important cell structures such as DNA, cell membranes, and other parts of cells. This damage can cause wrinkles and fine lines on the skin. Arginine is a powerful antioxidant that works by neutralizing these free radicals.

2. Improve skin hydration.

Arginine retains moisture in the skin and improves skin hydration. Studies have shown that arginine plays an important role in the synthesis of natural skin moisturizing factors such as cholesterol, urea, glycosaminoglycans, and ceramides. These factors help maintain skin hydration.

Another study evaluated the effect of topical arginine on epidermal water loss and found that arginine prevents water loss from the skin surface by increasing the urea content in the skin.

3. Keep skin young.

A lot of collagen is needed to keep the skin firm and prevent aging. Collagen supports skin health and makes the skin look younger and more radiant.

4. Promote wound healing.

Arginine's ability to support collagen production is essential for accelerating wound healing.

5. Safety of arginine

Alpha-amino acids such as arginine can be safely used in cosmetics and skin care products
