Epicutis Oil Cleanser is a breakthrough oil-cleansing formula that solves the primary problem with conventional oil cleansers: they don't rinse completely, leaving a greasy residue that disrupts the skin's microbiome and barrier. Epicutis Oil Cleanser uses two special botanical-derived fatty acid surfactants that create a gentle cleansing action on contact with water — lifting away makeup, SPF, sebum, and environmental pollutants completely, rinsing clean with no residue, and preserving the skin's natural lipid balance.The botanical fatty acid surfactant system emulsifies on water contact, transitioning from an oil phase (which dissolves lipid-based impurities) to a milky wash that rinses completely — without the greasiness or incomplete removal of conventional oil cleansers, and without the barrier-stripping effect of surfactant-based cleansers. Formulated without sulfates, conventional preservatives, fragrances, or any ingredient that would disturb the delicate skin microbiome or lipid barrier that the subsequent Epicutis treatment steps work to restore and maintain. 4oz/120ml. Epicutis is a Princeton University-rooted clinical skincare brand founded by dermatologist Dr. Steven Rosen, M.D., built around patented lipid bioactive technology (TSC — Disodium Tetramethylhexadecenyl Succinoyl Cysteine) developed at Princeton University. Each formula is designed around a minimal, clean ingredient philosophy — only ingredients that serve a clear functional role. Available at Beauty Riche — authorized Epicutis retailer with same-day shipping.
