Clays and clay minerals have been used in cosmetics and dermocosmetics for centuries, with therapeutic applications dating back to prehistoric times. This review discusses the types of clays and clay minerals used in cosmetics, their compositions, applications as active ingredients and cosmetic components, and formulation techniques. While much scientific literature describes clay characterization, few studies evaluate their efficacy in cosmetic products, particularly in haircare. Clays are valued for their natural, low-cost, and environmentally friendly properties, as well as their high surface area, rheological properties, and ion exchange capacity. They are used in various cosmetic forms, such as ointments, gels, creams, and pastes, and are effective in skin cleansing, moisturizing, and treating conditions like acne and dandruff. Clays are also used in makeup products and have antibacterial, antiseptic, and regenerative properties. However, specialized literature on clays in cosmetics is limited, and more research is needed to fully understand their potential. Clays are classified based on their mineralogical composition, with different types having distinct properties and applications. They are used in cosmetics for their ability to adsorb impurities, toxins, and excess oil, as well as their role in skin hydration and protection. Clays are also used in sunscreens for their UV protection properties, and their effectiveness depends on their mineralogical composition and particle size. Despite their benefits, clays must meet strict safety and purity standards to ensure they are safe for cosmetic use. The review highlights the importance of understanding clay properties, formulation techniques, and safety considerations to maximize their potential in cosmetics and dermocosmetics.Clays and clay minerals have been used in cosmetics and dermocosmetics for centuries, with therapeutic applications dating back to prehistoric times.
