[Visiting Canada from France] Recommendations for skincare products I should buy here, that are better or cheaper then France?

Any recommendations for skincare with glycolic acid, lactic acod, Azelaic acid, Benzoyde Peroxyde etc ? Is Azelaic acid 15 or 20% OTC here? What can i get OTC for rosacea?

I like the fact that here you can see on the bottle the concentration of each active (unlike France).
