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. 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. Directions Apply a few drops to face in the AM and PM before creams. A tingling sensation can be expected after application. If the sensation is too strong to tolerate, the formula can be mixed with other creams or serums of your preference before each application to reduce the strength. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.
