You need to keep a healthy supply of wet wipes and use them carefully, especially around the eyes of sex doll. Start with a clean surface and then carefully clean when changing colors or textures. Simple and cheap brush kits should be available at all retail outlets. Some cosmetic bags come with their own brushes and applicators. Note: I bought some lip liner colors that are basically crayon. They do not apply to silicones and may not be suitable for TPE dolls. The only thing I can do is to break the crayons. No makeup left on the lips of sex dolls.
