Inspired by the effects of neurotoxin injections, this serum is formulated with an Advanced Peptide Complex and a Glass Skin Complex to smooth nine types of contraction and expression lines to rejuvenate skin for a renewed glow. Neurotoxin injections are a popular in-office treatment used to treat expression wrinkles caused by muscle contractions. When paired together, P-TIOX and neurotoxin injections work synergistically to help reduce the appearance of wrinkles, delivering fast, long-lasting results. Versatile and innovative, this serum is also effective on its own to smooth skin, refine pores and reveal glass skin radiance in one week of use.
