This gel feels really good on the skin & absorbs quickly. I've been using it for about 2 weeks and I have not noticed any wrinkle reduction, although I suspect the collagen percentage must be pretty low so it would take 3-6 months before noticing results? Either way it was very inexpensive and the ingredients should be healthy for my skin so I will continue using it and keep my fingers crossed for miraculous wrinkle & stretch mark reduction! I would say this gel is a nice product for my skin and I would recommend it to my personal friends, especially since its so affordable.
