im not sure..
i will try search for u, maybe theres an online site but the best thing in to enter the sea for a few minutes and its pretty amazing
oh, i have only Baltic Sea around
i think i saw a store in the mall around me, will need to explore it and try
though lately i found some cosmetics that go well with my skin, but my skin is so damn allergic, every short travel and it reacts badly, it also reacts badly to water changes
cosmetics should be changes every now and then so next year i'll try Dead Sea for sure
