It has been scientifically verified that regular bathing in Blue Lagoon geothermal seawater is an effective treatment for psoriasis. By combining it with UVB light therapy treatment results can be maximized. The research provides the basis for Blue Lagoon's recognition as an officially recognized treatment option.

Research on healing power, composition and biology show that the geothermal seawater's ecosystem is unique in the world. Analysis on its composition confirms that it contains unique active ingredients: minerals, silica and algae.

Blue Lagoon geothermal seawater





Scientific studies of the geothermal seawater have shown that the microbial community is unique, since 60% of the organisms are novel on a species level.

The Psoriasis Area Severity Index (PASI) is an objective method developed to measure the severity of the psoriasis skin ailment. The result is a single figure score that can be used to measure the effects of the treatment.

Significant research has been conducted on the Blue Lagoon to determine its healing powers. The first studies were conducted in 1981. The results of the studies indicated a definite effectiveness against psoriasis. In 1992-1993, more comprehensive studies were completed. The studies proofed that regular bathing in the Blue Lagoon is an effective treatment against psoriasis.
