How it works

The product creates a base layer to prepare the skin for the application of foundation, potentially enhancing the foundation's adherence and duration. Dimethicone, with its smoothing properties, helps in skin conditioning, creating a silky texture. Ethylhexyl Methoxycinnamate functions as a UV filter, potentially contributing to some level of sun protection. Trimethylsiloxysilicate forms a film that may help in maintaining the makeup's appearance over time. Butylene Glycol assists in retaining moisture, contributing to a hydrated look. Titanium Dioxide, an opacifying agent, helps in providing an even-toned appearance. The inclusion of Perlite and Nylon-12 helps in refining the skin's texture and reducing the perception of imperfections. Rosa Centifolia Extract provides conditioning benefits, potentially leaving the skin feeling soft and prepared for further makeup application.
