摘要:
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.
摘要:
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.
摘要:
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.

摘要:
The present invention relates to a cosmetic or pharmaceutical emulsion for topical application to the skin comprising an irritating agent and at least one non-disruptive emulsifier. In a preferred embodiment the irritating agent is a retinoid. The invention also provides a method for decreasing the irritation on the skin caused by an irritating active agent in a topical cosmetic or pharmaceutical emulsion which comprises employing as an emulsifier at least one of an alkyl polyoside, a grafted water soluble protein on a hydrophobic backbone, and lecithin.
摘要:
Novel sulfhydryl group-containing amides and disulfide group-containing bis-amides useful for treating or preventing an abnormal biological condition or a disease, and/or improving the texture or appearance of the skin, as well as compositions containing amides and bis-amides and methods for their use are described. Such types of abnormal biological conditions or diseases include skin atrophy, i.e., the thinning and/or general degradation of the dermis often characterized by a decrease in collagen and/or elastin as well as decreased number, size and doubling potential of fibroblast cells, and other maladies including, but are not limited to dry skin, severe dry skin, dandruff, acne, keratoses, psoriasis, eczema, skin flakiness, pruritus, age spots, lentigines, melasmas, wrinkles, warts, blemished skin, hyperpigmented skin, hyperkeratotic skin, inflammatory dermatoses, age-related skin changes and skin in need of cleansers.
摘要:
A method for treating intact irritated or inflamed skin with a composition comprising at least one Histamine Receptor pathway inhibitor; at least one Lipoxygenase pathway inhibitor; at least one Cyclooxygenase pathway inhibitor and at least one Chemotaxis pathway inhibitor.
摘要:
The invention relates to a method for improving skin lipid barrier function by applying to the skin a composition 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.
摘要:
A method for repairing DNA damage in human keratinocytes by applying to the keratinocytes a composition comprising at least one CLOCK or PER1 gene activator and at least one DNA repair enzyme.
摘要:
A topical composition comprising at least one adipogenesis inhibitor and at least one adipocyte lipolytic agent and, optionally, at least one skin tightening agent; a method for improving the appearance of facial or body skin, treating the appearance of cellulite, or treating the face or body to improve the appearance of skin and uneven skin surfaces.
