i don't know. i tend to think the brands available at a pharmacy are of better quality, but of course it's only a general rule, in my case it is true.
avène is great. my mom has the range for sensitive skins, and she loves it. i don't like much the moisturizers myself, but the makeup remover is good.
La roche Posay has some good products, their moisturizer for dehydrated skins saved mine (i also like their mask for dehydrated skins). i love their sunscreens.
Bioderma has nice moisturizers for oily skins, i love their toner. and one of their shampoos called Nodé is fantastic.
i'll name also Eucerin.
