Unique OneBlade technology Philips OneBlade is a revolutionary technology designed for facial styling and body grooming. It can trim, edge and shave any length of hair. Its dual protection system – a glide coating combined with rounded tips – makes shaving easier on your skin. At the same time, its shaving technology features a fast-moving cutter (200x per second). This unique combination gives you a shave that's both efficient and comfortable – even on longer hairs. OneBlade does not shave as close as a traditional blade. OneBlade follows the contours of your face allowing you to effectively and comfortably trim and shave all areas of your face. 100% water resistant, so it is easy to clean: just rinse it under the tap. Shave with or without foam - whichever you prefer. The blades are designed for lasting performance. For optimal performance, you will only need to replace the blade every 4 months*. Replacement is easy and hassle-free. Attach the skin guard for an extra layer of protection on sensitive areas.
