Excellent serum, with a texture of thin cream, very good packaging, effective in brightness and fine lines quite quickly, for wrinkles it takes 8-12 weeks like all. It absorbs quickly and leaves a velvety skin. The only downside is the awful smell, it doesn't bother me but until I read other reviews (e.g. ulta) I thought it was spoiled! It does not contain a high percentage of retinol, it is low on the ingredient list, but the combination is good.
