The gel pools create a protective barrier for a comfortable shave. The gel is dermatologically tested and covers the skin like a protective film, and contains Pro Vitamin B5. The 5 blades with skin guards double the points of contact to smooth the skin and help to prevent irritation. Flip back the gel pools to use the top of the blade head to edge and trim those hard-to-reach areas such as under the nose. The handles are ergonomically designed.
