An academic study of the pathway of UV-induced pigmentation may have created a safe tan for sunseekers. Scientists at the Dana-Farber Cancer Institute, Harvard Medical School, have begun research and evaluation of the compound forskolin, which they believe darkens skin pigmentation successfully without the use of self-tanners and without sun exposure.

Impaired functioning of mitochondria is a very important factor in aging. Irradiation of normal human fibroblasts with UV was shown to increase the frequency of mutations in the mitochondrial DNA. Treatment of the fibroblast culture with a nanoemulsion containing coenzyme Q10 and vitamin E acetate was found to protect the mitochondrial DNA against UV-induced mutations.

This article discusses the synthesis of nanoparticles by inverse microemulsion polymerization and evaluates its potential to extract and release the fragrance linalyl acetate. The ability of the liposomes made from phosphatidyl choline and phosphatidic acid to extract organic molecules also was explored.
