Foil or Rotary Shavers – Which is better? – The Eternal Discussion

Foil or Rotary Shavers

“The eternal discussion”. Sounds deep, no? Not really. It’s just that deciding which is better – a foil electric shaver or a rotary model – becomes endless. The reason isn’t at all obscure.

Basic Definitions

It isn’t hard to define the difference between a rotary and a foil model. You’ve seen countless examples of both types of electric shaver. But doing it will reveal some points that lead to a useful comparison of pros and cons.

A foil model electric shaver is one covered by a foil. True, but not helpful. Let’s try again. A foil shaver is covered by a relatively large, curved rectangle of metal with a pattern of holes that arrange hair for efficient cutting. Underneath are a set of blades that vibrate left and right (or back and forth, if you prefer).

That raises a number of useful questions. What is that hole pattern? What makes them (more, or less) efficient? How do the blades interact with the foil cover? All good questions but let’s put them off for just a bit to introduce the rotary style so we can compare and contrast.

A rotary shaver houses a number of round heads (usually three to five) covering that number of rotating blades. That definition shows at once some of the important differences (and similarities) to a foil model.

The difference is obvious. One type of foil/blade system is rectangular the other is round. One type features blades that ‘shift’, the others whirl. The similarity isn’t as obvious but it’s important; both offer a set of holes of varying shapes and sizes that sit above moving blades.

Why are those similarities and differences important? By answering that question we’ll be able to explore the pros and cons of selecting one style of electric shaver over the other.

Pros and Cons

Closeness

In discussions of the pros and cons of foil versus rotary, you might often see the assertion that a foil gives a closer shave. Sometimes, but not necessarily so. It depends on the model, how well the blades are made and positioned in each, your face, and a dozen other factors. In general, many foils do give a closer shave than many rotary models, but it’s not universally true. One reason it’s true some of the time owes less to the rectangle-vs-circle aspect than other facets of the shaver’s design.

Speed

For example, a good foil model will likely have a very high vibration rate, as high as 14,000 cycles per minute for example. Some rotaries do have a very high rotation rate but it’s less common. That’s as likely due to cost (and the quality) as any inherent advantage. Speed does make a difference, though. Just as a fast-spinning lawn mower blade cuts better than one rotating slower (it cuts rather than tugs), so it is with a shaver. All this assumes other things are equal, of course: blade quality, hole pattern, and more.

Pattern

A more important design difference is that last one: hole pattern. It turns out that shaving closeness (and related aspects, like comfort) is to a large degree the result of that attribute.

Here’s where foil electric shavers tend to have an advantage. It’s just a lot easier to make a more efficient pattern in a relatively large curved rectangle than with a relatively small, thin disc. That hole pattern frequently consists of three different opening types. One type is often a short slit, another a rounder hole, and a third a (relatively) wide, long slot. There’s a lot of variation from one model to the next, of course, but in general that’s the common pattern.

The result is that hairs of different lengths can all be more efficiently lifted, pulled up slightly (and comfortably) and whacked off near the skin. When the ‘tug’ releases, the hair moves back deeper into the skin.

But that inherent advantage of a foil over a rotary can be wiped out by other factors. For one thing, rotaries have a hole pattern, too. A well-designed rotary can more than compensate for size and geometry (and even speed, to a degree) if compared, say, to a foil model that is just so-so. It’s simply that fewer rotary models have the complexity of hole pattern or the style more frequently used by a foil model.

Contour

Another important design aspect that distinguishes a foil shaver from a rotary is the overall shape of the covering. Clearly, in the first case it’s rectangular (though rolled) and the second covering is circular, as discussed several times already. But that shape has a big effect on closeness in a way not yet discussed. It influences where you can go and how easily.

You can certainly get a foil under and above your chin with ease. But you can’t get around the fact that a rotary is both smaller and shaped in a way that allows better access to all those natural curves and crannies of your face (or underarms, legs, and elsewhere, if used as ladies do).

The jawline near your ear, or the area around a very curved chin, is simply more accessible via a small disc than it is by a big rectangle. That’s especially true when the design of a rotary – as is often the case – lets the head ‘float’ in more directions. Foil designs could (and sometimes do, partly) flex around those curves. But here the rotary has an inherent advantage, and most designs make good use of it.

That’s one important reason that the blanket statement “a foil shaves closer” simply isn’t always true. Even ignoring the issue of comfort, closeness depends on more than just head/blade geometry and/or hole pattern; it depends on dynamics.

Cutting Style and Location

There are other aspects to shaving, though, than simply a close (or even comfortable) shave. For men in particular, you often want to trim sideburns or a mustache, or the edges of a beard. When women use an electric they often want to trim pubic hair, where getting close – but not too close – is important as well.

For that, a foil shaver clearly offers a big native advantage. The natural straight line of a foil makes it much easier to make a straight line on the bottom of a sideburn or to follow the line of a beard below the jaw.

Still, a rotary can eliminate any advantage here simply by including a trimmer, as many do. In fact, whether foil or rotary, those trimmers invariably do a better job in those situations than the main shaver itself. That’s what they’re put there for, after all.

Maintenance

One other area of comparison between a foil electric shaver and a rotary model has nothing to do with shaving, per se: maintenance.

Here, the foil has an inherent advantage that is not so easily overcome. Popping off the head of the rectangular unit and holding it is typically near effortless. Blowing or even rinsing is a breeze unless the head is so poorly designed you have to struggle unduly.

That said, it’s also usually easy to remove the head/foil covering the blades of a rotary model. Sometimes it’s too easy, which makes the rotary not as advantageous in this area. It’s a lot easier to lose that little disc, especially if you shave and clean in the shower, where they can too easily make their way down the drain.

All in all, though, it’s a pretty minor difference. That difference, as suggested just above, can often be more than compensated for (in either style) by the difficulty or ease of removal, the style of clip, and so forth.

The other style of maintenance – using an automated cleaning component – is a little trickier to assess. In my experience, foil units tend to have a cleaner that is a little easier to use, even when they’re no better in terms of vibration or cleansing solution. It’s typically easier – quicker, more stable – to place a rectangular shaver upside down in a cleaner.

However, even here I can’t make a broad statement without qualification. It depends on the specific models and the only way to compare fairly is case by case. Some rotaries have excellent cleaners both in terms of ease of use and quality of result.

Conclusion

After all that it isn’t hard to see why the question “Foil or rotary shaver, which is better?” generates eternal discussions. Every model – of either type – is unique, despite having much in common. Every face (leg, or underarm) is unique.

Aspects like noise, weight, body shape, and others are simply too varied (and too much a matter of personal taste) to draw any kind of reasonable comparison. Some foils are too big for some guys’ hands, some rotaries are too small. Some foil shavers are too heavy and some rotaries too light. Some foils are louder, but not all. Some rotaries are flimsier, but not all. And vice versa on all these aspects. There’s just too much variation in individual models to make overall comparisons between the two main types.

So, whether you evaluate them in terms of closeness, comfort, coverage, or maintenance, there’s only one thing you can truthfully say about which performs better – a foil or a rotary electric shaver: it all depends. Or, in other words, it comes down to personal preference.

Not an exciting conclusion, if you enjoy combat with only one winner, but inescapably true.

The Rash and Redness of Razor Burn and Bumps: More Than Just a Little Irritating

The Rash and Redness of Razor Burn and Bumps

Shaving is a fast and effective way to remove unwanted hair from the face or other parts of the body. When it goes “smoothly”, shaving is relatively hassle-free. Unfortunately, shaving doesn’t go smoothly for everyone. For some people, shaving leads to an uncomfortable condition called razor burn. Razor burn is often itching and uncomfortable and the symptoms can last for days or weeks. It’s a common condition that affects adults, mostly men who shave their face daily.

The Nature of the Bumpy Beast

Razor burn refers to skin irritation, redness and fine bumps that appear after shaving. Shaving is the most common cause of razor burn, but people who use a tweezer to pluck hairs can experience skin irritation, as well. Skin that’s irritated by the friction of shaving can become inflamed, leading to burning or itching in a recently shaved area. Razor burn is most common in men, although women can develop razor burn as well, especially when they shave their bikini area. The skin in the bikini region is more sensitive than other areas of the body.

Razor burn is sometimes confused with razor bumps also known as Pseudofolliculitis Barbae (PFB). Razor bumps are due to ingrown hairs that curl backwards and reenter the skin at an adjacent point causing irritation. The irritated areas become inflamed and small red bumps appear on the skin. These bumps often itch or burn. In some cases, the bumps become infected with bacteria. In almost all cases, the bumps burn or itch and are unsightly in appearance.

Razor burn is usually less serious than razor bumps. It generally heals more quickly and is easier to control. Razor burn can usually be prevented with careful shaving technique whereas razor bumps can be an ongoing problem in people who are susceptible to them.

The Real Culprits

Razor burn is usually a consequence of skin irritation due to poor shaving technique. It’s more common in males who shave their face since facial skin is more sensitive than skin on the arms and legs. Women can experience razor burn or razor bumps when shaving the bikini area.

Black males are at higher risk for razor bumps and ingrown hairs because they have curly hair. Curly or kinky hair is more likely than straight hair to grow backwards, and then reenter the skin. Once there, it can become trapped beneath the skin. This leads to skin irritation and inflammation. Ingrown hairs can become so inflamed that they become cystic and painful.

Another reason people with dark skin are at higher risk is because their follicles are slightly curved. This makes it easier for the hair to grow back at an angle and reenter the skin. Anyone with curly hair or curved hair follicles is at greater risk for razor bumps when they shave.

Some people appear to be genetically at risk for developing razor bumps due to variation in a gene that affects hair composition. This gene variation changes the structure of the hair in a way that makes it more likely to grow backwards and reenter the skin after shaving.

Enter the Complications

Most razor burn and razor bumps heal in a few days to a week, but some people experience complications. When razor bumps become inflamed, cells that produce the pigment melanin may respond by producing more pigment. This leads to dark spots on the skin that can take months to heal. This is known as post-inflammatory hyperpigmentation. It’s the body’s response to ongoing inflammation.

Post-inflammatory hyperpigmentation is more common in people with dark skin. In some cases, razor bumps can become so inflamed that scarring occurs. Rarely, in people at risk genetically, keloid scars can form. These large, unsightly scars are disfiguring, especially on the face.

Prevention is Key

The best way to avoid the discomfort and complications of razor burn and razor bumps is to prevent them in the first place. One way to lower the risk is to use proper shaving technique. Always use a sharp razor when shaving. Dull razors cause more skin irritation than sharp ones.

Shave in the direction that the hair grows, not against it, without applying too much pressure. Use shorter strokes to avoid pressing down too hard. Pushing down too firmly, especially with a dull blade, leads to more skin irritation.

Keep rinsing the blade with warm water to remove hair and dead skin cells that can interfere with smooth movement of the blade. Avoid pulling the skin taut to get a closer shave and don’t repeatedly shave the same areas. This increases skin irritation and the likelihood of razor burn and bumps. Reducing the frequency of shaving from daily to every other day can also reduce skin trauma and irritation.

It’s Electric

Using an electric shaver as opposed to a razor can reduce the risk of razor burn and razor bumps since electric shavers tend to be less irritating to the skin. Always use light pressure with a shaver to reduce irritation and trauma.

It’s important to replace the blades before they become dull. If a razor is the only option, choose one with a single blade. Razors with double and triple blades cut the hair too closely and cause more skin irritation.

Before, During and After

Another way to reduce the risk of razor burn and razor bumps is to apply a warm compress to the area before shaving. This softens the hair up so it can be removed without irritating the skin underneath. Use a thick, moisturizing shaving cream to help the razor glide more smoothly over the skin. There’s some evidence that shaving gels containing benzoyl peroxide reduce the risk of razor bumps. After rinsing, pat the skin dry gently with a towel instead of rubbing. This helps to reduce skin irritation and friction.

After shaving, rinse the shaved area with cold water to help close open pores. Then apply a moisturizing cream that’s made for sensitive skin. Look for one that has natural botanicals with anti-inflammatory activity like chamomile or aloe to help reduce inflammation.

Exfoliating the skin regularly helps to reduce razor bumps. Studies show that using skin care products that contain glycolic acid such as PFB Vanish boosts the removal of dead skin cells and smoothes the outer layer of the skin. This means there’s less skin irritation when shaving. Look for a product that contains 8% glycolic acid.

Prescription-strength retinoids used to treat acne may be helpful for preventing razor bumps, although it will take weeks or months to see benefits. They work by exfoliating and removing dead skin cells. They should be used with caution by people with darker skin, since they can irritate the skin and cause post-inflammatory hyperpigmentation.

When these measures fail to prevent razor bumps, laser hair removal or use of a chemical depilatory is an option. A word of caution – people with dark skin are at risk for post-inflammatory hyperpigmentation with laser treatments.

Relief at Last

People who already have itchy bumps and red, irritated skin may benefit from an over-the-counter hydrocortisone cream to reduce inflammation and control the itching. It’s best to reduce the frequency of shaving until the areas heal to avoid further irritating the already inflamed areas.

Severe cases of razor bumps may require topical or oral antibiotics to eliminate secondary infection. Benzoyl peroxide lotion or gel may also be helpful in cases where razor bumps are secondarily infected. For faster healing, reduce the frequency of shaving to a minimum whenever possible.

What You Should Remember?

Razor burn and razor bumps are a common and sometimes disfiguring problem. Using the right razor and proper shaving technique, as well as practicing adequate skin preparation beforehand can help lower the risk of these uncomfortably and unsightly problems.
