Frequently Asked Questions and Enquiries I am using eyelash extensions. Is it OK if I use COSME DECORTÉ make-up remover? Many eyelash extension salons advertise their use of beauty products containing oil. As our make-up remover was not designed with eyelash extensions in mind, we do not recommend its use in this case. We recommend you use make-up remover sold at the extension salon, which is specifically designed for use with extensions. Search by Product Category Questions about skin care.
