Acides Amines + B5 - Hydration Serum Quench your thirsty complexion with a little help from THE Ordinary Amino Acids + B5, a concentrated solution that will offer intense, non-greasy hydration for all skin types. Formulated with amino acids and amino acid derivatives to create a combined total concentration of 17%, this solution resembles the composition of amino acids found naturally within the skin, and in turn, will provide enhanced support to the skin's barrier. Upon regular use, elasticity will be improved, osmotic balance regulated, with any dryness or peeling reduced. Amino Acids + B5 also contains D-Panthenol, a pro-vitamin of vitamin B5 that will provide surface and below surface hydration while aiding in skin repair and reducing irritation to support the maintenance of healthy, glowing skin. HOW TO USE IT To use, apply a few drops to your face in the morning and evening before creams. Upon application, a slight tingling sensation may occur. If the sensation is too strong to tolerate, this formula can be mixed in with other serums or creams to reduce its strength.
