A gel, for cosmetic use, composed of a mixture of a polymer which forms a gel, a surfactant, and propionyl L-carnitine glycinate hydrochloride, useful for treating disturbances of the skin such as cellulite and wrinkles is described. In oxidizing the dielectric film, an oxidized gas is supplied to the dielectric film at a heat treatment. Bulk materials may be fabricated from these heterodiamondoids, and the techniques involved include chemical vapor deposition, polymerization, and crystal aggregation.
