Abstract: The present invention relates to methods and compositions for repairing adverse effects of the environment, daily stress, sun exposure, or pre-mature aging on human skin, comprising applying to the skin, prior to a period of bodily rest, a topical composition that contains resveratrol or a derivative thereof and at least one DNA repair enzyme.

Abstract: The present invention relates to topical compositions containing a dispersion of composite particles. Each of such composite particles contains one or more core particles encapsulated or entrapped in a polymeric shell. At least some of the core particles are formed of a material capable of causing generation of reactive oxygen species (ROS). Each of the composite particles further contains: (1) a first antioxidant co-encapsulated or co-entrapped with the core particles inside the polymeric shell for quenching or scavenging ROS generated in the vicinity of the core particles, and (2) a second antioxidant coated over the polymeric shell for preventing or reducing oxidative damage to the skin, such as lipid peroxidation. The particle dispersion of the present invention therefore can be readily formulated into topical sunscreen compositions with organic sunscreen agents susceptible to oxidative decomposition or degradation to provide improved protection against skin damage caused by exposure to UV light.

Abstract: Compositions and methods for enhancing repair of damaged DNA in skin cells. Topical compositions comprising at least one agent that upregulates circadian gene expression in skin cells and at least one non-circadian agent that delays mitosis in skin cells. Preferably, such compositions comprise one or more keratinocyte clock and per1 gene activators, along with SIRT1 or one or more sirt1 activators. More preferably, the sirt1 activator is a synergistic combination of specific peptidic sirt1 activators and resveratrol. Preferably, such compositions are easy to use, efficacious, cosmetically acceptable, chemically, thermodynamically and light stable, safe for topical use, have little or no side effects, and commercially feasible in a personal care marketplace.

Abstract: A skin care composition comprising at least one keratinocyte CLOCK or PER1 gene activator and at least one DNA repair enzyme; a method for inhibiting damage to human keratinocytes due to environmental aggressors by applying a composition comprising at least one keratinocyte CLOCK or PER1 gene activator and at least one DNA repair enzyme; and a method for repairing DNA damage in human keratinocytes.

Abstract: The present invention relates to a method of modulating a selected biological activity of a naturally occurring material having one or more biological activities in an extract of the naturally occurring material, the method comprising incubating the extract in a medium in the presence of an aerobically metabolizing microorganism, under suitable aerobic conditions, for a period of time sufficient to modulate the selected activity with respect to baseline activity of the unincubated extract. The invention also relates to the bioconverted material so prepared, and the use of same in cosmetic or pharmaceutical compositions.

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: The present invention relates to methods and compositions for repairing adverse effects of the environment, daily stress, sun exposure, or pre-mature aging on human skin, comprising applying to the skin, prior to a period of bodily rest, a topical composition that contains resveratrol or a derivative thereof and at least one DNA repair enzyme.

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: An emulsion cosmetic composition comprising at least one resveratrol derivative, a water phase, and an oil phase containing at least one linear or branched volatile or near volatile silicone and a method for delivering active resveratrol to the skin.

Abstract: An aqueous based cosmetic composition comprising at least one resveratrol derivative and a water phase containing at least one aqueous phase structuring agent; or an emulsion composition comprising at least one water phase, at least one oil phase containing at least one nonvolatile silicone, and at least one resveratrol derivative.

Abstract: An anhydrous color cosmetic composition comprising at least one resveratrol derivative and particulates; and an anhydrous emulsion skin care composition.

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

Abstract: The invention relates to a composition for topical application to the skin comprising effective amounts of a protease inhibitor and a cell differentiation enhancer. The composition is useful in promoting skin lipid barrier repair and maintaining the integrity of the lipid barrier. In this regard, the compositions can be used in the treatment and prevention of dry skin, and associated chrono/proto-aging conditions, in the treatment and prevention of irritation on the skin, in the treatment and prevention of UV-related damage to the skin, and in the enhancement of the retention of self-tanning.

Abstract: The present invention relates to a topical composition comprising a malodor-reducing effective amount of a rosemary extract, or active fraction thereof, in combination with a self-tanning effective amount of DHA. The invention also provides a method of reducing the potential for malodor generation of a DHA composition comprising adding to the composition an effective amount of rosemary extract or active fraction thereof.

Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumor, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a crude cartilage extract in an aqueous solution, this crude extract being fractionated to recover molecules of a molecular weight less than about 500 kDa. Some of the biologically active components of the extract are prepared by further fractionation. The cartilage extract can be used for treating diseases or conditions having etiological components selected from the group consisting of tumor proliferation, angiogenesis, inflammation, metalloprotease activity and collagenolysis. Several cosmetic applications based on the capacity of the liquid extract to improve skin conditions are also disclosed. A simple and efficient process for the preparation of cartilage extracts is also disclosed.

Abstract: The present invention provides a method of retarding desquamation of the stratum corneum, and maintaining stratum corneum thickness, by applying to the skin an effective amount of cholesterol sulfate. The retardation of desquamation can be useful in enhancing the skin's own UV protection, in prolonging the retention time of a sunless tan, and generally reducing the appearance of lines and wrinkles associated with both photo- and chronoaging.

Abstract: The present invention relates to a cosmetic or pharmaceutical composition for topical application to the skin afflicted with rosacea and treated with a retinoid. The composition for treating rosacea comprises an anti-irritating component and several other components for treating rosacea. The other components form a mixture of a salicylic acid, a phytosphingosine, green tea, hinokitiol, gorgonian extract, and polysaccharide. The invention also provides a method for decreasing the irritation on the skin caused by the heightened sensitivity experienced by skin suffering from rosacea. The other components are effective in treating the rosacea condition, but particularly, in treating the telangiectasic symptom of rosacea.
