Abstract: The non-therapeutic cosmetic treatment method includes at least: —applying an active composition including at least niacinamide onto the skin of a subject, and—illuminating the skin using at least one light source emitting at a wavelength of between 620 and 690 nanometres, preferably 660 nanometres, the illumination being carried out before, at the same time as or after the application of the composition. A device is configured for implementing such a method.

Abstract: A system and method for precision skincare that uses a set of skin measurements to generate a skin profile and a skin need and the skin need is used to identify and predict an optimal skincare product formulation customized for each user based on the skin need of the user. The optimal skincare product formulation may include one or more active ingredients selected based on the skin profile and skin need of the user and a delivery mechanism for the one or more active ingredients. The optimal skincare product formulation may be generated using machine learning techniques and may include outcome feedback that optimizes the machine learning models.

Abstract: Valeric acid esters of resveratrol and topical compositions containing the esters.

Abstract: Succinic acid esters of resveratrol and topical compositions containing the esters.

Abstract: The present invention is directed to a method for evaluating cosmetic materials for their efficacy in counteracting the effects of chronic stress on skin using a stress-induced premature senescence phenotype skin model. The present invention is also concerned with compositions containing a combination of actives for blocking or reversing the biological impact of chronic stress on the skin together with actives for rebuilding epidermis so as to restore elasticity.

Abstract: Valeric acid esters of resveratrol and topical compositions containing the esters.

Abstract: The present invention relates to a method for identifying materials having an efficacy for improving collagen turnover in the skin. The invention also concerns a composition containing a combination of a collagen-degrading active and a collagen synthesis-stimulating active for enhancing skin remodeling.

Abstract: Malic acid esters of resveratrol and topical compositions containing the esters.

Abstract: Succinic acid esters of resveratrol and topical compositions containing the esters.

Abstract: A method is provided for identifying a material having an efficacy for reducing color contrast between a hyperpigmented skin lesion and skin surrounding the hyperpigmented skin lesion without directly affecting melanocytes or melanogenesis. The method includes the steps of applying a composition containing a material to be tested to the hyperpigmented skin lesion; and after an interval of time, observing whether the composition has effected at least one of inhibiting proliferation of keratinocytes, stimulating differentiation of keratinocytes, and improving compressive deformation of dermal papillae, in a basal layer of epidermis in the hyperpigmented lesion of skin.

Abstract: An emulsion cosmetic composition comprising at least one resveratrol derivative, an aqueous phase, and an oil phase, having at least one silicone surfactant, and a method for preparing emulsions capable of delivering active resveratrol to the skin.

Abstract: Compositions and methods for modulating melanogenesis by modifying tyrosinase palmitoylation are provided.

Abstract: Compositions and methods for modulating melanogenesis by modifying tyrosinase palmitoylation are provided.

Abstract: A composition containing at least one alpha glucosidase inhibitor, and a method for ameliorating the adverse effects of aging and sun damage on keratinous surfaces such as skin by treating with a composition containing at least one alpha glucosidase inhibitor; as well as regimens and kits for treating skin.

Abstract: Compositions comprising a moisturizing agent, a desquamating agent, a mattifying agent and an agent that increases skin luminosity are disclosed herein. The compositions are useful for moisturizing, desquamating, mattifying, and increasing the luminosity in skin of an individual having a Fitzpatrick Skin Type IV, V, or VI. Also disclosed are methods for moisturizing, desquamating, mattifying, and increasing the luminosity in skin, comprising administering to an individual having a Fitzpatrick Skin Type IV, V, or VI, the present compositions.
