HI, sorry it took me soo long to answer.I havent visited the forum in monts.I used Neostrata 15 and I'm still using it.I tried some other product and I personally find neostrata the best.I purchse mine on ebay.com.It costs around 23$ plus 8$ for shipping to Europe (im from europe as well).one bottle lasts for about a mont and a half so it's no that expensive.If you have any questions just ask.
