A purifying clay face mask formulated with 90% hydro-activated clay blend and allantoin that visibly reduces the appearance of clogged pores and blackheads without stripping skin. This detoxifying mask combines fairly-traded Amazonian white clay (kaolin) and bentonite clay to draw out excess oil, dirt, and impurities while refining skin texture.
The hydro-activated clay blend becomes even more effective when mixed with water, as the clay particles shrink to target micropores and pore-clogging impurities. Amazonian white clay is rich in five key mineral salts with a porous structure that helps absorb excess sebum and detoxify skin. Bentonite clay works to unclog pores and leave skin soft and supple.
Key features include 94% of users reporting visible pore reduction after 3 weeks, 96% agreeing skin does not look oily after 3 days, and 96% finding the mask comfortable on skin. The formula is enhanced with sustainably sourced aloe vera to soothe and moisturize, oat kernel flour for antioxidant protection, and allantoin from comfrey root to calm and comfort skin. Unlike harsh clay masks, this gentle formula refines pores without causing excessive dryness or discomfort.
Apply a thin layer to damp, clean skin for 5-10 minutes until dry, then gently remove with a warm, wet towel. Recommended for use 2-3 times per week or as a spot treatment for blemishes. Suitable for all skin types including sensitive skin. Free from parabens, fragrance, mineral oil, and silicones.
