weird spa treatments shell therapy

Lava shell therapy

Now, this was novel. Everyone does hot-stone massages; they’ve become cliché. But at the Viceroy Zihuatanejo in Mexico, clients may be caressed by tiger-striped clam shells that, when heated, inspire relaxation through a combination of minerals, sea kelp, algae and salt water. The pairs of shells are bonded together and polished, so don’t worry about sharp edges. I predict that the firmness, smoothness and visual beauty of the shells will make them popular implements among the spa set.
