Guerlain Lingerie de Peau Compact Powder Foundation Refill Guerlain has created its first compact powder foundation refill so light that it blends seamlessly, like a second skin. The Bio-Fusion micro-mesh, a combination of stretch fibres and textile proteins of natural origin fuse with the epidermis for an optimal distribution of pigments. Powders, chosen for their capacity to marry a soft-focus effect with ideal coverage, fuse and melt at skin temperature. This unique technology promotes a smooth, soft and long-lasting finish, for an even complexion that remains matte and velvety all day long. Composed of hyaluronic acid, Lingerie de Peau compact powder foundation protects the skin’s moisture in order to maintain its suppleness and softness from morning to night. Finally, the dream of a perfect complexion is yours. A matte effect foundation becomes lingerie, and drapes your skin with the most natural-looking veil of beauty.
