Abstract: This invention relates to a topical, cosmetic or dermatological composition, comprising a 1,3 diglyceride having the general formula (I), in which the radicals R1 and R2 represent, independently of one another, a C13 to C40 saturated and linear alkyl radical, and at least one cosmetic or dermatological excipient for a topical application on the skin. This invention also relates to such a composition, or a 1,3 diglyceride having the formula (I), for its use in protecting the skin, in countering the weakening of the skin barrier and in preventing or reducing the penetration of exogenous molecules into the skin following a weakening of the skin barrier.

Abstract: The present invention concerns a combination of a retinoid and a diol and polyunsaturated fatty acid ester, a dermatological or dermocosmetic composition containing such a combination and use of same in the treatment of acne and the prevention of retentional lesions. The present invention also concerns a retinoid, optionally in combination with a diol and polyunsaturated fatty acid ester, for use in the prevention of retentional lesions.
