The unique colours of the Blue Lagoon

The blue colour of the Blue Lagoon is caused by the reflection of sunlight from very small silica molecules in the geothermal seawater. This is similar to what happens in the atmosphere where the sunlight is reflected from the atmosphere's molecules and give the sky its blue colour.

Blue Lagoon algae is the lagoon’s most distinctive organism. Iceland’s long days of summer are the algaes peak growing conditions. The algae flourishes and the green color dominates the blue one.

New scientific studies show that both Blue Lagoon silica and algae have effective properties against skin aging. Blue Lagoon silica and algae are key ingredients in Blue Lagoon skin care products.
