Combination Cream Improves Photodamaged Skin

VILLEJUIF, France—In a study published in the International Journal of Cosmetic Science, researchers found topical application of a combination of retinol, lactose and glycolic acid significantly improved the appearance of photodamaged skin (2008;30(3):175-182) (DOI:10.1111/j.1468-2494.2008.00441.x). In a double blind, placebo-controlled, clinical design, 40 female volunteers applied a cream containing retinol, lactose and glycolic acid on one side of the face, and a placebo cream on the other side twice daily for 12 weeks. The clinical assessment and the objective instrumental measurements showed the active treated side was significantly improved at the end of the study compared with baseline and the control-treated side.
