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.

The present invention achieves bio-mechanical stimulation of collagen synthesis in skin cells and reduction of the appearance of fine lines and wrinkles on the skin by applying a polymeric composition onto the skin in a manner so as to create surface tension that mimics the natural mechanical tension found in youthful skin.
摘要:
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.

摘要:
A method for stimulating collagen synthesis in aging skin cells in need of treatment by topically applying a composition comprising at least one extract from Laminaria genus, at least one extract from the Narcissus genus, and at least one peptide that stimulates sirtuin 6 activity in the form of a peptide or a yeast extract where the peptide is component of the extract; and a treatment composition comprising at least one extract from Laminaria genus, at least one extract from the Narcissus genus; and at least one peptide that stimulates sirtuin 6 activity.
