使用
grapefruit extract (Citrus paradisi) is reported as having antiseptic and skin-conditioning properties. It is indicated as beneficial for oily skin. Fresh grapefruit juice contains vitamin C and is very acidic. As such, in high concentrations, it is too caustic to use on the skin and face. There should be no problem, however, at normal use levels. The extract obtained from the juice is preferred over that of the rind, as there is practically no vitamin C available in the rind. Furthermore, unless properly obtained and processed, fertilizers and insecticide residues on the rind may provoke blemishes and allergic reactions in sensitive people. As vitamin C is considered an unstable component, grapefruit extract’s value in cosmetics depends on the method of extraction and the product’s formulation.
