Abstract: The invention relates to the use of various extracts of the Nephelium lappaceum plant for increasing the firmness and/or elasticity of the skin and/or mucous membranes, by increasing type I and/or type V collagen and/or LOX-L, fibulin-5, emiline-1 and/or fibrillin-1 gene and/or protein expression, and/or by decreasing CYR61 expression, in the skin and mucous membranes. Another subject of the invention relates to the use of said extracts in a cosmetic composition comprising at least one cosmetically acceptable excipient. Another subject further relates to a cosmetic care method comprising the application of the extract according to the invention or of a cosmetic composition comprising it, for increasing the firmness and/or elasticity of the skin and/or mucous membranes, by increasing type I and/or type V collagen, fibrillin-1 and/or LOX-L, fibulin-5, emiline-1 and/or fibrillin-1 gene and/or protein expression, and/or by decreasing CYR61 expression, in the skin and mucous membranes.

Abstract: Novel cosmetic and dermatological uses of an extract of Cistus monspeliensis The invention relates to the non-therapeutic cosmetic use of an extract of Cistus monspeliensis for increasing and/or maintaining tissue homeostasis in the skin and/or the mucous membranes and/or the skin appendages, by increasing and/or maintaining the barrier function and/or cell differentiation in the skin and/or the mucous membranes and/or the skin appendages. Another subject relates to a non-therapeutic cosmetic care process notably comprising the topical application of the extract of C. monspeliensis or of a cosmetic composition comprising same. Yet another subject relates to the extract of C. monspeliensis, for its use for preventing and/or treating diseases induced by a decrease in the gene and/or protein expression of ECM1, advantageously lichen sclerosus or lipoid proteinosis, and/or for preventing and/or treating scars.
