A novel guard structure of a razor is shown including rows of elongated hard plastic protrusions having rounded (e.g., not sharp or pointed) tips arranged on a tip curved profile. The rounded valleys between the protrusions are also arranged on a curved profile which may be different than that of the tip curved profile. The valleys encompass an inner protrusion volume which increases going back to front end of the guard structure. Preferably, the front end volumes are larger than the back end inner protrusion volumes to assist in trapping and distributing shaving aid. In one embodiment having six protrusions, the inner protrusion volume between a second and third protrusion is the largest, while a volume between first and second protrusion is the second largest volume. The guard structure is disposed in front of the blades formed within the housing and may extend past the front end of the housing.
