The Blue Lagoon’s storied waters come from volcanic aquifers 2000 meters within the earth. In this subterranean realm of searing heat and immense pressure, freshwater and ocean water converge, becoming the extraordinary, mineral-rich resource that gave life to the Blue Lagoon: geothermal seawater.
Geothermal seawater’s benefits for the mind and body have been researched for four decades. Rich in silica, algae, and mineral salt, the water strengthens, renews, and moisturizes the skin—bringing radiance and rejuvenation while stimulating circulation. With its profound benefits endorsed by scientists and doctors, it has become the basis of medically-sanctioned psoriasis treatments and the cornerstone of Blue Lagoon skin care.
While geothermal seawater is beneficial for the scalp, it can leave the hair matted and unmanageable. For this reason, we encourage visitors to use conditioner before and after experiencing the lagoon.
