The first electric shaver came in 1915 on the market. Compared to wet shavers dry shaving was initially not as thorough. For sensitive skin , however, an electric shaver is more suitable.
What is an electric shaver?
The electric shaver was patented in the year 1898th In 1915 came the first dry shaver on the market. but still he worked on the basis of a mechanical Servomotors which rotating blades drive. Only in the thirties of the twentieth century small electric motors have been developed for the shaver. The dry shaving was then referred to as a safety razor, because the knife block is protected by a foil. Violations could not occur.
Later an electric shaver with an oscillating armature motor was developed by Jacob Schick. It is an oscillating system. On the market this device came in 1937 by the company Remington from the United States.
After the Second World War, could enforce developed in 1939 by Philips rotating 3-blade shaving system. The development of the electric shaver has today led to a similarly good quality shaving shavers as in hand. Skin irritation occur in electric shavers on even rarer than in wet shavers.
Shapes, styles & types
Electric Shaver occur in two variants in the basic structure. So there are shavers with multiple shearing blades which perform rotating movements. The other variant consists of shavers, which have a cutter.
The basic structure of an electric shaver is very simple. It only consists of a cutting part and an electric motor. Today, there are shavers, releasing the built emulsions to achieve a more perfect shave. In part, it allows the technology already to surpass shaving with electric shaver compared to wet shaving. In any case, the cost of shaving with electric shavers are significantly lower than in the wet shave, because at that after 8 to 12 shaves the blade should be replaced.
Among the latest high-tech models of electric shavers today among other rotary shavers, dry shaver with density sensor, dry shaver with laser or dry shaver with cooling. Rotary shaver ensure effective skin contact by pivoting shaver heads. When dry shaver with the density sensor whisker density is determined and at the same time adjusted the vibration frequency of the shaver thereon. With the laser-dry shaver the exact cutting line is displayed, whereby the dry shaving can be made extremely accurately. In dry shavers with cooling the skin is already pleasantly cooled during shaving.
In electric shavers, there are also special models for women. These devices are commonly referred to as Lady Shaver. It is, however, more a marketing ploy than the need shaver having to develop for women or men specifically.

Before shaving with an electric shaver, the face should be thoroughly cleaned. However, it is important that the beard before the dry shave is also dry. The dry shaver cuts on dry skin most effectively.
The direction in which the shaver is moved during shaving has no effect on the shaving. However, should first the most vulnerable points are shaved because the apparatus warms up with time. Sensitive skin otherwise react with irritation when heated. After shaving use a will aftershaves recommended because it refreshes the skin and also acts anti-inflammatory.
Most shaving is not as perfect as in the wet shave, because the hairs are not directly on the skin are cut. For sensitive skin, dry shaving wet shaving is preferred however. The dry shaving with the electric shaver is also not as time consuming as wet shaving.
