By Subodh / August 29, 2014

With time, technology is making inroad into all aspects of human life. Even less tech savvy people are getting used to embracing technological innovations with open arms. Shaving used to be a largely manual method. A majority of people still shave using regular razors, shaving gel and brush every day. However, popularity of electric shavers is on the rise. It offers convenience and you need not use gels, water or shaving cream. That can be quite nice on a winter morning. It does not cut skin when used properly.

Types of Electric Shavers

There are plenty of electric shaver models in the market and choosing the apt one can be tedious. There are models that come with additional features. For example, you may find some electric shavers that are waterproof and using them with water and gel is possible. There are models that come with various attachments.

No matter how costly or affordable it is, an electric shaver has a DC motor inside its body. The model needs to be charged either through rechargeable or disposable batteries or mains outlet. The motor is used to turn a gear system which in turn rotates small blades fitted on top of the razor.

Foil And Rotary Shavers

Electric shavers can broadly be classified into two types, based on their working mechanism- foil and rotary shavers.

Foil Shaver

In a foil shaver, the surface of the blades is covered by thin metal layer and this is the foil. This makes it somewhat gentler on skin surface. The slots in this foil trap beard and hairs, allowing a very close shave. It is ideal for trimming straight edges, especially for trimming around your sideburns. These shavers have oscillating blades enclosed behind thin, perforated steel foils. These shavers create a buzzing sound when you use them.

Use a foil shaver if you:

  • Need to shave almost daily
  • Your facial hair is not very thick
  • Want to have close shave
  • Want precision in shaving
  • Have sensitive skin

Rotary Shaver

As evident from the name, Rotary shavers are made to trace the face contour. When you move it on cheek and chin in a circular manner, the hairs get cut off completely from the skin. The circular motion of these shavers makes them easier to apply in areas like the chin and neck. These shavers have circular blades. These shavers also make less noise compared to foil shavers. They are also more flexible to use and you can use circular motion or up and down movement. To get the best results from these shavers, you may need to squeeze face or mouth to let the circular surface of shaver glide through follicles easily.

You can use a rotary shaver when you:

  • Are not a frequent shaver
  • Find the facial hair grows in various directions
  • Do not have sensitive skin
  • Have thick facial hair

Using Foil And Rotary Shavers To Perfection

Whether you use rotary or foil shaver, you would like to get a shaving experience that simulates conventional shaving with foam and a razor. Unless you are using a model that is waterproof, you need to ensure the skin is dry, but not coarse before you use a shaver.

To get precision shaving from either type of shaver you need to practice following precautions and steps:

  • You need to prepare the skin for shaving with electric shavers. While a majority of these models are made to work without water, you can use other skin emollients than gel or foam to soften skin and hair follicles. You can use quality beard oil or pre shave lotion.
  • It is better if you can take a bath before shaving with electric shavers. It will make the skin softer and make it ready for shaving.
  • Your skin type and direction of hair growth also plays an important role in shaver selection. You need to use shavers in the best suitable way to avoid skin irritation.
  • Like every electronic gadget, shavers also need maintenance. Apart from charging the batteries or the shaver itself, you need to use the provided brush to clean the blades from time to time. Some companies offer special lubricating agents to sharpen the blades.
