Cosmetic compositions containing resveratrol and retinoids.

Polygonum Cuspidatum Extract Resveratrol CAS.NO 510-36-0 photo picture image What is claimed this Cosmetic skin care compositions invented by cosmetic and skin reseachers from USA suggested as:
 1. A cosmetic skin care composition comprising mainly:
 (i) transresveratrol in an amount of from 0.00001 to 10 wt. %;
 (ii) a retinoid selected from the group consisting of retinoic acid, retinol, and retinyl acetate; and
 (iii) a cosmetically acceptable vehicle;wherein said retinoid is present in an amount of about 0.001 to about 10 wt. %.
 (iv) trans-resveratrol is an essential ingredient of the inventive composition.Pure resveratrol and crude form of trans-resveratrol may be obtained commercially from MDidea Group or MDidea Exporting Division in large quantities.
 Cosmetic skin care compositions containing transresveratrol in combination with selected retinoids.This invention from some researchers of USA showed mechanism and suggestions as following:
 In general, the amount of resveratrol in the inventive compositions is in the range of from 0.00001 to 10% by weight composition. Preferably in order to lower cost and maximize the effect the amount of transresveratrol is in the range of from 0.001% to 5% and most preferably is in the range of from 0.1% to 5%.
 The inventive compositions further comprise a retinoid selected from the group consisting of retinoic acid, retinol, retinyl acetate, and retinyl linoleate. It has been found that these retinoids, but not retinyl palmitate, act synergistically in combination with resveratrol.
 Most preferred retinoid is selected from retinol, retinyl acetate and retinyl linoleate, because of its proven cosmetic efficacy.
 The retinoid is generally employed in the inventive compositions in an amount of from 0.001 to 10%, preferably from 0.01 to 1, most preferably from 0.01 to 0.5% by weight of the compositions.
 The composition according to the invention also comprises a cosmetically acceptable vehicle to act as a diluant, dispersant or carrier for resveratrol and the reinoid in the composition, so as to facilitate their distribution when the composition is applied to the skin.
