In 2026, the men's body groomer has become an essential part of male grooming. Let's be honest: most guys still use the first trimmer they get their hands on, the one that's been in the drawer for years or the same one they use for their hair. The result is often irritation, repeated passes over the same area, and a frankly disappointing outcome.
However, choosing the right men's body groomer really changes the experience. Not just for the visual result, but for daily comfort on all areas of the body: chest, back, armpits, legs, and intimate parts. Each area has its specificities, and one single trimmer is not suitable for all.
In this guide, we'll explain everything: the criteria that truly matter when choosing your device, how to use it area by area, what length to choose according to your preferences, and the classic mistakes to avoid so you never regret your purchase again.
Why a men's body groomer, and not just any one
A men's body groomer is not at all like a hair clipper. Body areas have different contours, curves, and skin sensitivities. An overly aggressive blade or an unsuitable device directly leads to irritation, redness, or even cuts in places where you really don't want them.
The classic body groomer is designed for relatively large surfaces and skin that tolerates a blade pass well. It is perfectly suited for the chest, stomach, back, and legs. But as soon as you approach sensitive areas, especially intimate parts, the rules change completely.
This is where choosing the right tool makes all the difference. Using a body groomer on the testicles or pubic area carries a real risk. We'll come back to this in detail in the dedicated section. Let's admit it, those who learned the hard way don't make the same mistake twice.
Essential criteria for choosing your body groomer
The blade: the number 1 criterion
This is the core of the matter. A bad blade, and no matter what else, the experience will be poor. For a men's body groomer, you want a blade that glides without pulling, cuts cleanly without rubbing, and withstands regular use without dulling in two weeks.
Classic stainless steel blades do the job on large areas like the chest or legs. On more sensitive areas like the groin or armpits, a blade specifically designed to avoid direct contact with the skin truly enhances comfort. For intimate parts, an even more specialized blade is needed: we'll discuss this in the dedicated section.
Battery life and charging
A body groomer that dies mid-session is a guaranteed hassle. For full body grooming, allow at least 40 to 60 minutes of actual battery life. And in 2026, USB-C charging should be the norm: you plug in any cable, anywhere, and you're good to go.
Avoid battery-powered models. The long-term cost, the performance that drops as soon as the batteries weaken, and the environmental aspect: everything argues against this mode of operation in 2026. It's an unnecessary constraint that the best body groomers have long since abandoned.
Waterproof: essential or optional?
Clearly essential. Shaving in the shower is more comfortable (skin is supple, hair is clean), and it greatly facilitates blade cleaning. A non-waterproof device forces you to shave dry, which increases friction and irritation, especially on sensitive skin.
Check that the device is certified IPX5 minimum before buying. This guarantees that you can use it underwater without risk for years.
Available cutting lengths
The more cutting lengths you have, the more freedom you have with your style. For the body, you generally need a range from 0 mm to 12 mm depending on the areas. Chest, stomach, legs, intimate parts: each area has its preferences, and you don't want to be stuck with one or two imposed lengths.
A well-designed comb that easily fits without moving during use is also an often underestimated criterion. Nothing is more frustrating than a comb that detaches at the wrong moment.
Ergonomics and grip
The body has hard-to-reach areas, and a trimmer that is too rigid or bulky will complicate your life. A compact format, a non-slip finish, and a well-placed center of gravity truly make a difference when working in complicated angles.
This is particularly true for the back and intimate areas, where every centimeter of maneuverability counts. A light trimmer that you can easily hold with your fingertips is far better than a powerful but bulky one.
Area by area: how to use your men's body groomer
Chest and stomach
This is often the area where you start, and that's good: it's the most accessible and least delicate. Start by passing against the direction of hair growth to cut the bulk, then go back over in the direction of growth to even out.
On the stomach, the skin can be slightly looser. Gently stretch the skin with your other hand for a cleaner result. There's no need to press hard: a good blade does the job on its own, without forcing.

Back
The back is the final boss of male grooming. Hard to reach, impossible to see properly, often neglected for this reason. Yet with a little organization, it's perfectly manageable on your own.
The trick: use a back mirror or a bathroom mirror positioned at an angle. Start with the shoulders, then gradually move down. A light trimmer that you hold with your fingertips truly facilitates complicated angles. And if you have someone nearby, you might as well take advantage of it.
Armpits
An area often neglected by men, yet: maintaining your armpits truly changes daily comfort, especially in summer or during sports. Perspiration, odors, friction: a short, controlled length solves many problems without requiring a full shave.
Raise your arm, stretch the skin, and gently go against the hair growth. Armpit skin is thin, so there's no need to force it. A few passes are enough to achieve a clean and comfortable result.
Legs and arms
These are the least sensitive areas of the body, and therefore the simplest to maintain. A classic body groomer is largely sufficient here. The goal is generally not a clean shave but maintenance: reducing volume for a neater look, especially for athletes.
On the legs, go against the direction of hair growth. On the arms, pay attention to the elbow and the crease of the wrist, which are slightly more sensitive and deserve a gentler pass.
Intimate parts: a dedicated trimmer is different
Let's be honest: using your classic body groomer on your intimate parts is a bad idea. The skin of the pubis, testicles, and perineum is significantly thinner and more fragile than that of the torso. A standard blade designed for large areas will rub, pull, or even cut in places where you really don't want cuts.
This is precisely why billy, the men's intimate trimmer exists. billy's ceramic blade is specifically designed for sensitive areas: it cuts hair without ever coming into direct contact with the skin. The result is zero cuts even on the testicles, zero ingrown hairs on the pubis, and possible use everywhere: perineum, intergluteal cleft, groin.
"Finally a trimmer with which there's no apprehension of cuts. And the fact that you can use it in the shower is great!" — Antoine R., billy customer
billy offers 5 cutting heights (0, 3, 6, 9, and 12 mm), an integrated LED to illuminate hard-to-reach areas, and USB-C charging. In less than 2 minutes in the shower, intimate areas are maintained, stress-free and without repercussions. And no classic body groomer can promise that for these areas.

What length to choose by area
There's no universal right answer here, and that's a good thing. "Your hair, your style": you choose what suits you best, not a trend or a magazine.
Some benchmarks to guide your choice. On the chest and stomach, 3 to 6 mm gives a neat look without appearing too groomed. On the legs and arms, 6 to 9 mm is enough to reduce volume without going too short. On the armpits, 3 mm is often a good compromise between comfort and discretion. And on intimate parts, billy lets you choose from 0 to 12 mm according to your preferences of the moment.
The idea is to test. Most people start with a longer length and adjust downwards rather than the other way around. It's much simpler to correct. And if you change your mind the following week, the trimmer is there for that.
Classic mistakes to avoid
The first mistake is to trim dry on irritated or dry skin. A shower before, or during, is the best way to prepare the skin and make the experience truly comfortable. Dry skin resists more, and that's a guarantee of redness post-session.
The second mistake is never cleaning your blade. Hair accumulating between the teeth reduces efficiency and can cause pulling. A quick rinse under water after each use is enough if your body groomer is waterproof.
Third mistake: forcing it by pressing too hard. A good blade doesn't need pressure. The harder you press, the more you increase the risk of irritation. Let the trimmer do the work; your role is just to guide the movement.
And finally, forgetting to change the blade. A dull blade no longer cuts cleanly and compensates by repeated passes that fatigue the skin. On sensitive areas, in particular, this is where irritation and ingrown hairs appear first.
Maintenance and lifespan: how to make your men's body groomer last
Minimal but regular maintenance is enough to keep a body groomer in perfect condition for years. After each use, rinse the head under cold or lukewarm water. If your trimmer is not waterproof, use the small brush provided to remove hair residue between the blade teeth.
Store it in the open air rather than in a closed drawer: residual moisture needs to evaporate to prevent any proliferation on the blade. This simple gesture truly extends the device's lifespan.
As for the blade, the general rule is to change it every 3 to 6 months depending on the frequency of use. For billy, the replacement ceramic blade is available for €29 and attaches in a few seconds. A fresh blade is like a new trimmer: the result is incomparable.
FAQ: everything you need to know about men's body groomers
Can the same trimmer be used for the body and intimate parts?
Technically yes, but it is really not recommended. The skin of intimate areas is much thinner and more sensitive than that of the chest or legs. A blade designed for the body can cause irritation and cuts in places where it is particularly uncomfortable. For intimate parts, a dedicated trimmer like billy is clearly the best option.
Should you shower before trimming?
It is highly recommended. Showering softens the skin, slightly opens the pores, and moistens the hair, making the cut cleaner and less irritating. If your trimmer is waterproof, trimming directly in the shower is also an option.
How often should you trim your body per month?
That depends on the area and the desired length. For general body maintenance, a session every 1 to 2 weeks is sufficient in most cases. For intimate parts with billy, 2 minutes every 1 to 2 weeks is generally enough to maintain the chosen length.
Is the body groomer suitable for sensitive skin?
Yes, provided you choose the right model. A quality blade with a gentle pass and no excessive pressure is perfectly compatible with sensitive skin. The main thing is to avoid repeated passes over the same area and to hydrate the skin well after each session.
Can you trim your back alone without help?
Yes, with a little organization. A double mirror or an adjustable mirror is enough to see what you're doing. A light trimmer with good ergonomics facilitates complicated angles. It's less obvious than an accessible area, but entirely feasible by taking your time.
What is the lifespan of a men's body groomer?
A well-maintained device can last several years without problem. What wears out first is the blade. Regularly changing the blade every 3 to 6 months depending on use gives a second life to your trimmer indefinitely.
Can billy be used on the whole body?
Billy is primarily designed for sensitive areas: intimate parts, pubis, testicles, perineum, groin, armpits. It can obviously be used on other body areas.
Do you need a cream or gel before trimming?
No, that's one of the great advantages of the body groomer compared to a razor. No need for foam, gel, or cream. A shower is enough as preparation or conclusion. It's simple, quick, and leaves no residue to clean.
