Arginine

An Amino Acid to Help Soothe, Hydrate, and Support Skin Recovery

Arginine is a naturally occurring amino acid found in the skin and throughout the body. In cosmetic formulations, it is often used for its moisture-binding properties and its potential to support visible skin recovery, particularly in formulations designed to comfort or replenish stressed skin.

For skin experiencing the effects of hormonal changes—such as increased dryness, surface irritation, or slower recovery—arginine offers a gentle way to help restore softness, balance, and comfort.

A Brief History of Arginine in Skincare
Arginine is one of the key building blocks of proteins and plays an essential role in maintaining the skin’s natural hydration and repair processes. In skincare, it is often included as part of amino acid complexes, where it supports surface smoothness and helps fortify the skin’s outer layers.

Because it naturally occurs in the body, it is well tolerated and often used in sensitive-skin formulations, including those aimed at hydration, exfoliation recovery, and barrier support.

How Arginine Supports Skin During Menopause
As collagen declines and the skin’s recovery slows, arginine may help maintain a more balanced, moisturised, and resilient appearance—especially when used alongside peptides, humectants, or resurfacing agents.
