I have been using Acyl-Glutathione for almost 30 days. I am absolutely shocked by the results I have seen in such a short period of time. I have noticed a tremendous improvement in the fine lines around my eyes as well the creases in my "elevens". But, the area that I am SO shocked by is the area above my eyebrows, where I have deep "expression" (horizontal) lines! I used to treat this area w/ injections... BUT, *never* again! Acyl-Glutathione has improved the elasticity and firmness of my skin, as well as the overall appearance of the accelerated signs of aging that I am experiencing. My skin feels tighter and more radiant! I love Acyl-Glutathione!
