MODEL RELEASED. Beauty treatment. Woman having a face pack applied to her face. A face pack, also called a facial, is a beauty treatment where the face is covered in a material (often called 'mud' or 'clay') that is intended to improve the feeling and appearance of the skin. It is intended to moisturize the skin and improve the condition of the pores. The mask can include skin oils, and other chemical nutrients. A facial is usually combined with other beauty treatments such as a steam and scrub, and a face massage. Photographed in Paris, France.
