This product works. The gel is very easy to apply and quickly gets absorbed into the skin.Within a few days of using it I noticed the change in my complexion, my skin looks and feels softer and younger.I have used retinol serums in the past and they work, but this one works much better than anything I have ever tried. I should also mention that even though I have a sensitive skin, this product did not cause any irritation or redness. This is a great product!This company also sells skin brightening & lightening cream, and I canג€™t wait to try it out
