- Abstract: The appearance of skin strongly influences people´s self-esteem and well-being. Among the characteristics that affect the most, we can cite acne and wrinkles. Therefore, minimizing those characteristics by using cosmetics has important value for the consumer. Nowadays, there is a demand for natural ingredients, mainly concerning cosmetic products. The use of clays in beauty care is old, with therapeutic uses since Prehistory. There is an essential advantage in using clays for cosmetic purposes, as it is a low-cost, environmentally friendly, natural, and abundant ingredient, which is chemically inert with a low level of toxicity (when in adequate conditions), easy to apply and remove, dries, and hardens fast. In this research work, we aimed at developing and investigating the effect of formulations containing red, green, and black clays as active components in oiliness reduction, and firmness and elasticity improvement in vivo, as well as characterizing clays mineralogically. All clays presented different compositions. Black clay was the one with the simplest mineralogic content, lowest density, and smallest particle size. It was the richest in Si and Al. Green clay presented expandable smectite and the highest density. Red clay presented the largest particle average size and was the richest in iron content. By thermal analysis, clays presented two characteristic events: the water loss (dehydration) and the dihydroxylation of kaolinite, turning into meta kaolinite. In Sebumetry, clays showed a significant reduction of skin oiliness on the forehead in both concentrations after 2h of contact compared to control, baseline, and placebo. However, after 4h (2h after removal), no significant difference was observed with the control. In the Cutometry, clays did not present significant efficacy in skin firmness and elasticity improvement when compared to control and placebo sites, thus, further studiesshould be performed comparing the efficacy of different vehicles with dispersed clays. Finally, clay mask formulations were developed with black, red, and green clay dispersed in an oil-free gel vehicle, which proved to be adequate for oily skin
