Abstract: Topical compositions comprising a retinoid, a low irritation polymeric cleansing agent and a cosmetically-acceptable topical carrier are provided. Such compositions provide improved retinoid activity for treating for example signs of skin aging, acne, or rosacea.

Abstract: This invention relates to personal care compositions and methods of treating topical skin conditions using compositions containing polymeric sulfur Sn. The compositions of this invention may also preferably contain —SH-containing compounds such as thiols.

Abstract: Methods of treating skin in need of treatment with retinoids are provided, which comprise cleansing the skin with a cleansing composition comprising a low irritation polymeric cleansing agent prior to treating with a retinoid. This improves the activity of the retinoid for treating for example signs of skin aging, acne, or rosacea.

Abstract: Low pH compositions for topical administration to skin are provided. They comprise a buffering agent having a pKa of about 2.8 to about 4.2 and a cosmetically acceptable active ingredient having a pKa within about 1 unit of the pKa of the buffering agent. The composition has a pH of about 3.3 to 4 and a buffer capacity of at least about 0.15. A method of increasing the topical delivery of a cosmetically acceptable active ingredient having a pKa of about 2.8 to about 4 is also provided.
