How about a bath in waters rich in silica and sulfur? It's not a crazy new fashion, but The Blue Lagoon, one of the most visited spots in Iceland. White silica mud gently cleanses and exfoliates, while blue-green algae nourish and soften skin.
Bathing in the milky-blue water is said to be beneficial to people suffering with skin disorders, such as psoriasis, and the complex has a Research and Development project to find cures for other skin ailments.
The temperature of the water ranges from 37° to 39° Celsius and if this appeals to you, you’ll find the Blue Lagoon surrounded by lava fields and black sandy beaches in Grindavik on the Reykjanes Peninsula, 39km from the capital Reykjavik, in south west Iceland.
