Kiehl's Rare Earth Deep Pore Cleansing Masque is a cult-favorite, dermatologist-recommended pore-purifying clay masque featuring Amazonian White Clay — a rare, highly absorbent clay sourced from the Amazon River Basin with exceptional sebum and impurity adsorption properties. It visibly minimizes pore appearance, removes deep-seated impurities, and controls excess oil for a clearer, more refined complexion after a single use.Amazonian White Clay (Kaolin from the Amazon region) is the star active — providing deep physical adsorption of excess sebum, environmental pollutants, and cellular debris from within pores, visibly reducing pore size and surface shine immediately after use. Aloe Vera provides soothing activity that counteracts the potential irritation of the clay — leaving skin refreshed rather than tight or dry after masking. Oatmeal Extract calms and soothes, improving tolerability for sensitive skin. The formula absorbs excess oil and unclogs congested pores without stripping the skin's natural moisture balance, making it suitable for oily and combination skin types that also require hydration.Apply a thin, even layer to cleansed face, avoiding the eye and lip areas. Leave on for 10 minutes. Rinse thoroughly. Use 1–2 times per week. Available at Beauty Riche — authorized Kiehl's retailer with same-day shipping.
