Arginine

Arginine is a naturally occurring amino acid that is considered essential for human development. As a skincare ingredient, it offers antioxidant benefits and plays a role in repairing skin damage. Its moisturizing properties have also been studied and widely recognized. Additionally, this essential amino acid plays a key role in the skin’s natural production of restorative substances such as proline and urea.

Arginine can be of animal or synthetic origin; both are equivalent in terms of skin benefits. Researchers are currently exploring the use of arginine-derived cosmetic surfactants as a more “biocompatible” alternative to traditional forms.

In the field of hair care, arginine has been shown to reduce damage caused by oxidative coloring or bleaching processes. It is known to promote hair growth. You can find it in many care curbing hair loss and increasing their resistance.
