Description

TECHNICAL FIELDThe present invention relates to topical compositions providing a high level of hydration and which comprise a vitamin B.sub.3 compound for regulating the condition of skin.BACKGROUND OF THE INVENTIONMany personal care products currently available to consumers are directed primarily to improving the health and / or physical appearance of the skin. Among these skin care products, many are directed to delaying, minimizing or even eliminating skin wrinkling and other histological changes typically associated with the aging of skin or environmental damage to human skin.Skin is subject to insults by many extrinsic and intrinsic factors. Extrinsic factors include ultraviolet radiation (e.g., from sun exposure), environmental pollution, wind, heat, low humidity, harsh surfactants, abrasives, and the like. Intrinsic factors include chronological aging and other biochemical changes from within the skin. Whether extrinsic or intrinsic, these factors result in visible signs of ski...

Problems solved by technology

Whether extrinsic or intrinsic, these factors result in visible signs of skin aging and environmental damage, such as wrinkling and other forms of roughness (including increased pore size, flaking and skin lines), and other histological changes associated with skin aging or damage.

Extrinsic or intrinsic factors may result in the thinning and general degradation of the skin.

There is also a flattening of the dermal-epidermal junction which results in weaker mechanical resistance of this junction.

Current vitamin B.sub.3 formulations, however, can be drying and irritating.

Thus, user compliance with current vitamin B.sub.3 formulations is less than ideal.
