Dear banana Girl, the UGL compleax is a new component peeling agent, made out of marine source, here you have a 3% of it, which is very mild but efficient, you have also other peeling agents in here, but it is all mild, so safe and easy to use, in fact I do use it every night without any problem, please use a adequate sunscreen during the days, always! Regards from Zurich, Salvo

PS: wish the pads where larger, too small for my opinion
