Put simply, an epilator is a hair removal device that works by gripping several hairs at once and physically pulling them out. Although epilation is similar to waxing, the two processes differ in that epilation does not result in the loss of cells from epithelium tissue found throughout the body. The best epilator usually does not have parts requiring regular replacement, although if your epilator works by using a spring, this may need replacing periodically.
Several varieties of epilators exist. Epilators vary based on their power source (power cord, rechargeable battery and disposable battery varieties exist) and hair removal method (some remove hair by trapping it in a slowly-rotating coil of wire, and others use small tweezers to pull hair out). Epilators are usually not used over small areas, and are more suited to areas with large amounts of hair, such as the legs or arms, as using a tweezer on smaller amounts of hair may be more efficient.
Epilation devices have evolved rapidly in recent years. The head of a modern device will feature a number of metal plates melded into plastic. When the head of the epilator rotates, the plates move together and apart, similar to tweezers. Hair caught in between the plates is pulled out as the head of the epilator rotates and is discarded by the epilator immediately, creating an efficient method of epilation allowing for the quick completion of all stages in the hair removal process.
The method of epilation for the face is different to the way epilators are used on the rest of the body. Epilators designed for the face are manually operated, and do not use any form of electrical power. Face epilators usually contain just one spring with two handles attached. The spring must firstly be made to form a curve and then placed on the facial hair to be removed. Turning the handles will cause the hair caught between the spring coils to be pulled out.
One issue related with epilation is very similar to a problem experienced by those who wax or shave. If your hair is brittle, it may simply snap rather than be pulled out. Hair that snaps off will look very similar to face stubble experienced by males due to shaving, but unlike face stubble, will not be concentrated in one area as brittle hairs may not be common on your skin. Regular epilation will reduce problems associated with brittle hair, as well as reducing discomfort.
