Hi! I came across the website in early March. I had just ordered RoC multie-correctional night cream. After purchasing what seems like a million different products, this one seemed to help right away for wrinkles. When I came across this website I read about medsmex. I was a little skeptical but went ahead and ordered. I didn't see about alldaychemists until today. I received my two Retin-A 0.05% tubes today and am excited to give them a try! I didn't realize the tubes would be as big as they are. Anyway, I am curious Mirecka about the 0.1% as opposed to 0.05% - I take that it is twice as strong. I am wondering if I should have ordered one of those instead of two 0.05%. Also, can someone give me more info about alldaychemists? I checked their website and the prices are unbelievable! Actually half the size but $2 or $3 a tube? Am I reading that right? LOL! It also says comparable to Retin-A. Has anyone used their products? I am also curious about shipping as it was pretty expensive from medxmex. Thanks everyone! Glad I found this site. Everyone seems so very helpful!
