After using this product for about a week to ten days you see results. The fine lines under my eyes have almost completely disappeared. The deeper more defined lines have softened significantly. I use this product twice a day, once in the morning and once at night. This is a great product for early 30 something users who want to maintain their youthful appearance. It is also good for women in their 40's and 50's who just want to refresh their youthful appearance around their eyes by diminishing the look of their fine lines and smoothing their deeper more defined lines in the eye area.
