Earth Harbor BLUE CRUSH Marine Perfecting Mask

This water-activated powder mask turns into a creamy paste when mixed with water, delivering the smoothing benefits of clays without the overly tight, dried-out feeling some clay masks leave behind. It’s meant to gently polish away buildup and soften rough texture, while marine and botanical ingredients support a more refreshed, balanced-looking finish.

What I Like

  • EWG rating: 3, based on entering the ingredient list into the EWG Skin Deep Analyzer.

  • I like that this is a clay mask that’s meant to turn creamy instead of going super dry and cracking on the skin.

  • It’s a good “texture reset” mask when skin feels a little dull or backed up, but you still want it to feel comfortable after you rinse.

  • The ingredient list is primarily focused on clays, marine support, and a bright citrus-vanilla blend.

Things to Keep in Mind

  • This includes multiple citrus peel extracts plus bergamot and grapefruit. If you’re fragrance-reactive or your skin is already irritated or over-exfoliated, this may feel too stimulating.

  • Clay masks can be drying if overused. If your skin runs dry or you’re in a flare, shorter wear time is usually the sweet spot.

Sensitive Skin & Pregnancy Considerations

This formula does not include retinoids or other commonly pregnancy-restricted skincare actives. The most likely sensitivity triggers here are the citrus components, especially for rosacea-prone, eczema-prone, or barrier-impaired skin. Patch testing along the jawline for a few nights is a reasonable step if you know citrus or aromatic ingredients can be reactive for you.

Essential oil transparency note: essential oils and aromatic extracts can carry trace contaminants depending on sourcing and processing. Feather & Nest prioritizes brands that test for purity and focus on responsible sourcing to help minimize unwanted impurities.
