Re: Smile Lines -I hate them
It says it “Each 100 mL contains tretinoin - 0.0075 g and hydroquinone - 2g”
This is a lot less than the lowest prescription amount of tretinoin (0.025%) - this worked for me but I know some people move up in concentration after their skin becomes used to this amount.
The hydroquinone is just going to lighten skin.
Personally, I wouldn’t use this product.
