Great results when used once per week. Does smooth the skin, improve texture and eliminate fine wrinking around mouth and forehead. It is possible the skin is slightly thicker, but I really can't tell.
I have used it for 6 months. The eye area was treated with no adverse effect(once every 2 weeks). It improved the eye area, minimally but would not dare to use it more often. Few side effects in the beginning, limited to flakiness.
Overall, a great product at a great price. I have almost half the tube left after 6 months.
