An essential component of the real Icelandic spa experience is the ancient white silica mud mask custom at the Blue Lagoon. Unique to the lagoon, this naturally occurring ingredient has a strong mix of silica, algae, and minerals that cooperate to revitalise and cleanse the skin. The right application technique is gathering the silica mud from the wooden boxes positioned around the lagoon, applying a thin, even layer to clean skin, and letting it dry for 5–10 minutes before gently rinsing with the lagoon water. Studies have indicated that this particular mix of minerals can lower inflammation, increase natural collagen generation, and enable skin elasticity to improve. Every guest should definitely try this treatment since regular users of the silica mud mask have reported notable changes in skin structure and appearance.
