In 1995, Blue Lagoon Skincare introduced its first product: the Silica Mud Mask, a game-changing formula inspired by the Lagoon’s geothermal seawater and its bioactive properties.

This iconic mask was created for psoriasis patients visiting the Blue Lagoon’s medical clinic. “Visitors undergoing treatments in the silica-rich waters wanted a way to continue their care at home,” explains Ása Brynjólfsdóttir, Director of Research & Development for Blue Lagoon Iceland. The result was a product that became a cornerstone of the brand.

Thirty years later, the Silica Mud Mask remains a standout for its ability to purify pores, soothe skin, and strengthen the barrier function. This is more than just a clay mask—it’s an all-in-one facial reset. Lena Dóra, head esthetician for Blue Lagoon Retreat Spa, shares five ways to incorporate this must-have into your skincare routine.

1. As a Traditional Mud Mask

The classic way to use the Silica Mud Mask is as a wash-off treatment. It deep cleans pores and soothes the skin, making it suitable for all skin types. “Apply a thin layer to the face or focus on areas like the T-zone,” suggests Lena Dóra. Leave on for 5-10 minutes, rinse, and finish with the BL+ Serum and your favourite face cream. 

2. As a Spot Treatment

Feel a breakout coming on? Use the Silica Mud Mask as an overnight spot treatment. “It significantly reduces inflammation in the skin,” says Lena Dóra, leaving problem areas calmer and less irritated by morning.

3. As a Gentle Scrub in the Shower

For a deep cleanse, mix the Silica Mud Mask with the Lava Mask. This combination offers exfoliation and hydration, softening the scrub’s texture while strengthening your skin. Apply, massage gently, and let it sit while you finish your shower routine before rinsing off.

4. As a Mild Exfoliant for Sensitive Skin

Perfect for sensitive skin, the Silica Mud Mask doubles as a gentle scrub during spa facials. “Its fine silica particles are incredibly soothing,” says Lena Dóra. At home, mix the mask with water and massage in light, circular motions. This preps your skin to better absorb serums and moisturizers.

5. As a Psoriasis Soother

True to its origins, the Silica Mud Mask remains a soothing solution for psoriasis. Apply to affected areas and leave on for 5–10 minutes before rinsing with warm water. Its calming properties help reduce irritation and discomfort.
