Abstract:

The measuring results of a dielectric constant analysis of creams samples that were not exposed to sunlight or X-rays and which were measured while it is attached to the water (the water was considered as a phantom for human skin tissue) showed that QV and Cetaphil creams have the highest dielectric constant (about 3500) compared to the rest of the creams Fair & Lovely, Diana, and Rose. After creams were exposed to sunlight the dielectric constant of Fair & Lovely, QV, Cetaphil, Diana, and Rose was increased to about 1000. And after creams were exposed to X-ray the dielectric constant of Cetaphil cream increased to 4,000 and the rest of the creams Fair & Lovely, QV, Diana and Rose the dielectric constant raise slightly up to 1200. These changes may lead to the ability to ion exchange between the cream and the human skin (perspiration in the skin).
