Water Source – The Blue Lagoon is filled with natural mineral water from volcanic aquifers 2000 meters under the earth. It’s a wonderful combination of freshwater and seawater: geothermal seawater. The silica, algae, and salt-rich water repairs and strengthens the skin.

Though the water is a byproduct of the local geothermal power station. Superheated water from the ground is used to move turbines that make electricity. After that the water passes thru a heat exchanger to supply heat for a municipal water heating system. After which the water flows into the lagoon. The water in the Blue Lagoon renews every 40 hours.

The all natural water is not artificially disinfected and rich in minerals, PH 7.5 and salt content 2.5%. Still it contains no foreign bacteria, such as fecal bacteria, environmental bacteria, fungi, or plants. It is a self-cleaning ecosystem. It has been gifted a Blue Flag for more than a decade.

History – After the power plant opened in 1976 the runoff formed hot springs pools. A psoriasis patient soaked in one in 1981 and noted that it improved his symptoms. Bathing there rose in popularity and facilities officially opened in 1987. The Blue Lagoon company formed in 1992. There was a psoriasis clinic opened in 1994. A year later the Blue Lagoon introduced their own line of skin care products, which contained silica, algae, and salt.
