Abstract: The present invention relates to novel peptide compounds having the following formula [R1R2N—CH(Ra)—CO]a-(AA1)m-(AA2)b—X1—X2—X3—Y1—Y2—Y3—X4-(AA3)n—[NH—CH(Rb)—COOR3]c. It also pertains to cosmetic and dermatological compositions comprising one or more of these peptide compounds and to their uses in the cosmetic whitening of human skin and for the manufacture of a dermatological preparation intended to depigment human skin.

Abstract: A cosmetic skincare process intended to prevent and/or treat at least one cutaneous sign of aging, includes the topical application to the skin of a composition containing at least one active agent capable of stimulating tensin 1 expression. The cosmetic use of an active agent capable of stimulating tensin 1 expression, for preventing and/or treating at least one cutaneous sign of aging, an extract of elemi or of Canarium indicum L. or of Canarium luzonicum or of Canarium commune and a cosmetic composition containing the extract are also disclosed.

Abstract: A method of treating aging of skin including applying a therapeutically effective amount of an anti-aging dermatological care composition including at least one cosmetic formulation agent and oligogalacturonides having a degree of polymerization between 1 and 5 that stimulates adherence of basal keratinocytes to laminin V and/or collagen IV and reduces communication disturbances between a subject's dermis and epidermis and reduces diminishment in interkeratinocyte cohesion within the epidermis, to skin.

Abstract: A dermatological composition including a therapeutically effective amount of an agent stimulating adherence of basal keratinocytes to laminin V and/or collagen IV that resolves communication disturbances between a subject's dermis and epidermis and diminishment in interkeratinocyte cohesion within the epidermis.

Abstract: The subject of the invention is the use of a lipid extract of Andiroba for the inhibition of glucose-6-phosphate dehydrogenase and its application to the inhibition of adipocyte differentiation.

Abstract: The subject invention relates to a method of diagnosing epidermis differentiation disorders in a patient by obtaining an epidermis sample from the patient, adding to the sample, antibodies that specifically bind to an antigen of the stratum corneum, the said antigen being specifically recognized by BC 21 monoclonal antibody and detecting the presence or absence of the antibodies that are specifically bound to the epidermis sample.

Abstract: The subject invention relates to monoclonal antibodies which react with antigenic determinants which are present of the stratus corneum of human epidermis. Furthermore, the invention also relates to methods of using such monoclonal antibodies in immunoassays. One monoclonal antibody of the present invention which is particularly useful is BC 21.
