i do not know what peptides are but i love them [SEP] i am in love with this moisturizer first off i have to talk about the quality of the bottle not only is it gorgeous but it is soft like a babys butt before you even open the bottle you know their claim of luxury is true the pump is quality as well i have had some that are all over the place i use one pump for my neck and one for my face i tend to have oily areas on my face but this seems to be reducing that problem the scent is faint which i like but i love that it is made in america and not tested on animals great product
