Philips Lumea uses an innovative light-based technology called IPL (Intense Pulsed Light), derived from the technology used in professional beauty salons. Philips has adapted this technology for effective use in the safety and comfort of your own home. Philips worked closely with skin experts to develop this technology. For more than 10 years Philips carried out extensive consumer research on IPL technology with more than 2000 women. Philips Lumea applies gentle pulses of light to the hair root. As a consequence, the amount of hair your body grows gradually decreases. Repeating the treatment leaves your skin beautifully hair free and touchably smooth Our clinical studies have shown significant hair reduction in as little as four bi-weekly treatments resulting in smooth hair-free skin. To maintain these results, simply repeat the treatment when needed. Time between treatments may vary based on your individual hair regrowth Philips Lumea works effectively on (naturally) dark blonde, brown and black hairs. As with other light-based treatments, Philips Lumea is NOT effective on red, light-blonde or white/grey hair. This product is also NOT suitable for dark skin. Use with confidence to remove hair on the face (upper lip, chin) and body parts including legs, underarms, bikini area, belly and arms. For extra safety the integrated skin tone sensor measures the treated skin complexion at the beginning of each session and occasionally during the session. If it detects a skin tone that is too dark for this product it will automatically stop emitting pulses. Philips Lumea has five adjustable light energy settings to ensure gentle but effective treatment. Used correctly, Philips Lumea's IPL treatment is safe and gentle to use even on sensitive skin and sensitive body areas Larger window with optimised design for faster treatment and better visibility Gentle on your skin Main application mode enables sliding motion for more convenient and continuous application. Philips Lumea is a complete solution that comes ready to work straight out of the box. More importantly, it does not require any replacement lamps or gels.
