The Braun Silk·expert Pro 5 is an at-home Intense Pulsed Light (IPL) hair removal system that uses IPL technology to damage and disable hair follicles, leading to visible and permanent hair reduction. It is safe for light to dark skin tones and automatically adjusts the energy level to suit the skin tone. The device comes with various attachments, a user guide, and a Venus razor and blade. Users are advised to avoid exposure to artificial light sources and activities or skin products that may irritate the skin for 24 hours after treatment, and to use sunscreen when the treated areas may be exposed to the sun. The device has been positively reviewed for its effectiveness and ease of use. However, some users have reported that it can be painful, and others have raised concerns about the high price and the need for regular treatments. The materials used in the device are not specified in the available sources.
