The elastomer of cosmetics refers to the organosilicon elastomer, which is a polymer of siloxane or modified siloxane with three-dimensional network structure, generally in powder, gel and lotion form. It can well prevent some minor problems when making up, so you can get a perfect makeup look by avoiding such problems.
