We've used the Pharmacy in Grand Case so I'm not sure about others but that one has staff that speak English and are very helpful at recommendations.

One thing I found out was that Vishy products in USA do not contain the same ingredients as Vishy purchased in SXM. That bought in SXM did not cause my skin to breakout but those bought in USA did.

Don't know if that is the same with LaRoche-Possay; however I've purchased their sun screen for face that was recommended by our dermatologist, at a lesser price than here at home.

The pharmacy in Maho carries many lines found in USA.
