Legume/vegetable compositions and methods for treating post-inflammatory hyperpigmentation
US Patent 8106094
Publication date: Jan. 31, 2012
Assignee: Johnson & Johnson Consumer Companies Inc.
This invention relates to methods and compositions for treating and ameliorating skin conditions including post-inflammatory hyperpigmentation (PIH). More particularly, this invention relates to compositions containing certain natural extracts, salicylic acid and natural or synthetic retinoids. Various approaches to treating acne, photodamage and other skin conditions have been attempted, including treatment with vitamin A acid, i.e., tretinoin, and natural retinoids or retinoid precursors such as vitamin A alcohol, i.e., retinol. However, according to the inventors, topical treatment with retinoids can be irritating to the skin. In addition, oral treatment with retinoids has been found to have teratogenic effects. Thus, it would be desirable to find a topical treatment for acne and PIH.
In accordance with this patent, the inventors developed compositions and methods for treating and ameliorating acne and PIH that contain salicylic acid, nondenatured plant extracts—preferably legume products and more preferably, soy products in fluid or solid form—and at least one natural or synthetic retinoid or retinol compound. The novel compositions were clinically proven to reduce PIH.
