How Does An Electric Razor Work – Rotary and Foil Razors

how do electric razors work

Have you ever peered down at the electric razor in your hand and wondered how electric razors work…? When you think about it, an electric razor is a clever and sophisticated invention designed to make men’s grooming fast and fuss free.

Rotary Versus Foil Electric Razor, What’s The Difference Between Them?

Both razors deliver outstanding shaving results with different technologies. Whether a rotary or a foil razor is more suitable, depends entirely on such factors as your shaving routine, type of facial hair and personal preferences.

How Foil and Rotary Electric Razors Work

The foil section of the razor refers to the ultra-thin layer of metal which covers the surface of the blades. The holes or slots you can see in the foil, traps the hairs, allowing the electric razor to shave much closer to the skin, thereby giving you a smoother close shave than a rotary shaver. If you are looking for a precise finish such as trimming your sideburns, mustache or beard, then a foil electric razor is the one to go for. For people who shave every day, foils work best.

The blades on foil razors are enclosed behind very thin steel foils that are perforated. The blades oscillate at extremely high speed and work to lift the facial hair up into the blades to give you that super smooth and close shave.

Rotary Electric Razors

 Rotary units on the other hand have revolving or spinning heads. You will usually see three heads in a triangular shape. These rotary razors are designed to closely trace the contours of the face as you move the electric shaver in a circular motion.

The hairs slip into the openings in the three circular heads and are cut off completely. A rotary razor is very simple to maneuver around the more difficult problem areas of the face such as the chin and the neck which can be harder to get to with other kinds of shavers. If you have a lot of facial hair, a rotary razor gives you the best results.

These Are A Good Choice For Cutting Longer Thicker Hair

They are excellent at cutting longer thicker hairs and for those men who don’t have a daily shaving routine, especially on the weekends. When Monday morning rolls around and you want to look clean-shaven and professional for the office, a rotary electric razor will tick all the boxes.

Rotary Razors Can Closely Follow Facial Contours

Rotary razors have 3 circular blades which spin and flex in the unit to closely follow the contours of your face. As these blades swivel and flex on their own, they are much better than a foil razor at following the outline of your face and neck.

Another Plus, These Shavers Are Quieter

Another benefit of rotary razors, they make less noise than a foil shaver, that offer you the additional benefit of letting you shave however you want to… In a side to side manner, circular motion or up and down. Plus, they do better with longer hair.

Most brand-name shavers come with a 30 day and sometimes more, money back guarantee. Experts state it takes about 30 days for your face to become familiar with any new shaver you buy. There’s chance you’ll notice a major change in the results of your shaving after that initial adjustment, so keep at it from at least a couple of weeks with any new razor you buy. If you are really unhappy with your new electric razor, then utilize the money back guarantee.

What Brands Of Electric Razor Should You Buy?

The premium brand names of shavers from Braun, Panasonic and Phillips Norelco are known for the quality of their razor construction and shave results. They all have long histories of production and these brands definitely perform better than budget brands in performance, durability, ease of use and comfort, making them much better value in the long run than a budget buy.

Most importantly, these well-known, brand-name shavers are backed up by decent warranties which we feel it is a really good thing, as no matter how good the brand-name, any electric razor can have some durability concerns.
