This is the. A.G.E. Interrupter Ultra Serum. I have been a huge fan of this brand for years so was so excited to try this serum especially because it is an anti aging product. This serum is designed to help lift and tighten as well as reduce wrinkles. It has a concentration of 34.6% Flavo-Proxylane to help reduce signs of aging impacted by collagen decline and glycation, including wrinkles, and laxity. LTKBeauty LTKOver40
