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:
The invention relates to composition having enhanced biological activity, the compositions comprising at least one structured water. In particular, the compositions contain a combination of I and S waters and a biologically active agent, in which the activity of the agent is increased relative to its activity in a non-structured water composition.

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.

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:
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.
