The single most often made mistake in using a D/E razor is applying too much pressure. A quality, well-made razor will have sufficient weight of its own to exert enough pressure. Apply NO added pressure - just allow the razor to glide across the skin without pushing into it. Bearing down on the razor will not necessarily result in a closer shave, but it will remove at least the top layer of skin cells, a condition commonly called “razor burn.” Razor burn actually is exactly the same thing as “rug burn” or “road rash.” Though the latter two are typically more severe (even if it is more fun getting them) they really are exactly the same thing, a superficial abrasion resulting from the forcible removal of skin cells. A soft blanket will prevent rug burn, leather pants will safeguard against road rash, and NO PRESSURE ON THE RAZOR will solve razor burn.
Hold the razor firmly and direct it where you want it to go. Some shavers favor short strokes, others prefer long sweeping strokes. Which is right for you will depend largely on your particular beard conditions. Generally speaking, the coarser or thicker the beard, the shorter the stroke should be. A very fine or sparse beard will present less resistance to the razor and permit a long, smooth stroke.
Strive to maintain a thirty degree blade angle relative to the skin. While this will not be possible on every area of the face – Ear lobes, noses, and other obstructions often make it impossible, thirty degrees is the optimum blade angle and should be used whenever possible. You achieve this angle by raising or lowering the razor handle. This is particularly important when following contours such as around the chin or jaw line. Often in these areas very short choppy strokes work well.
Most nicks or cuts happen when the razor’s blade is allowed to make first contact with the skin. To avoid this, allow the safety bar to contact the skin first and lift the razor handle until you achieve the desired angle, then begin your forward motion. Once you’ve become more experienced this won’t be necessary.
