The Philips OneBlade Intimate is designed to protect your sensitive skin in areas like your armpits and intimate area. It features a unique skin protector that provides an extra layer of defense against skin irritation. You can choose to leave a little hair by using the included trimming comb. This device utilizes unique OneBlade technology with a fast-moving cutter (100x per second) that effectively cuts through any hair length. The SkinProtect blade, with its triple protection system, rounded edges, bridge, and rounded tips, is engineered to prevent skin irritation such as razor bumps and razor burn. Shave and trim with enhanced skin protection using this single device. The attachable 3mm body comb allows for quick and easy trimming of intimate hair in any direction. Durable stainless steel blades maintain their sharpness for up to 4 months (based on two full shaves per week; actual results may vary). The OneBlade is fully waterproof (IPX7), enabling wet or dry shaving with or without foam. For optimal results, dry shaving is recommended. To clean the product, simply rinse it under the tap.
