This concentrated solution includes Amino Acids and Amino Acid derivatives creating a combined total concentration of 17% (by weight). This resembles the composition of Amino Acids found in the skin's own Natural Moisturising Factors and provides enhanced barrier support, elasticity, osmotic balance and desquamation. The formulation also includes a 5% (by weight) concentration of D-Panthenol which is a pro-vitamin of Vitamin B5 to provide surface and below-surface hydration while aiding in skin repair and anti-irritant functions. The Ordinary Amino Acids + B5 offers non-greasy hydration support for the maintenance of healthy, functioning skin. It may cause a temporary tingling sensation upon application. If desired, the formula can be mixed with other serums or creams upon application to reduce its strength. Free from alcohol, nuts and gluten. Vegan.
