ProsBattery lasts for five hours (!)Has three adjustable comb lengths depending on your preferences2025 Holy Grail Beauty Award winnerConsSome reviewers say the shave isn’t very closeWhy we love it: When I traveled to Miami to celebrate my birthday, this bikini trimmer from Bushbalm was one of the first things I threw in my travel bag. Why? Because I was able to charge it before my trip, then never had to worry about it dying on me in the middle of a pre-pool trim, thanks to the battery that lasts a full five hours. (TBH, I actually didn’t even charge it before—I’ve actually only needed to charge this once in the last six months, lol.)And while I could wax poetic about the battery forever, I mostly love how powerful this little trimmer is while still feeling gentle against my skin. I rarely use it with the guard on, but I love having it as an option when I want a slightly longer length between waxing appointments. And it’s fairly quiet, which is great when you’re sharing a hotel room or have nosy aunts in the room next door at Christmas—ya know. Precisely, all the reasons we gave this a Cosmo Holy Grail Beauty Award in 2025.One Cosmo editor says: “I’m so prone to ingrowns, it’s not even funny, so I’m always looking for a tool that can get me smooth and keep me smooth. The BushBalm is that tool. The trimmer gets pretty much as close to the skin as you can get without causing nicks and is so easy to use that I could do it with my eyes closed. It does the job and does it well, and I love that it’s waterproof in case you want to use it in the bath or shower. I’m also obsessed with the ingrown hair oil from BushBalm—it makes the perfect pairing.”—HANNAH CHUBB, FORMER LIFESTYLE EDITORAttachmentsOne extra guardTrimming guide length3mm and 6mmPower sourceRechargeable batteryBattery life5 hoursWaterproof?YesProsSmall blade is helpful for grabbing all the tiny hairs you might miss with a razorLightweight handle is easy to use in the showerWhy we love it: For getting super close without nicking yourself, this Philips OneBlade device was made for getting into all the little crevices of your bikini line and intimate areas with precision. If there’s any straggling hairs after you shave, this is a great extra tool to have on hand for getting them. But don’t worry if you’re clumsy (like us), the blade isn’t too sharp. This waterproof trimmer is great for in the shower too, thanks to the lightweight handle.Attachments1 trimming guideTrimming guide length3mmPower sourceRechargeable USB cordBattery life30 minutesWaterproof?YesAdvertisement - Continue Reading BelowProsHas a really long battery life, according to testersDual-ended design is easy to store and travel withConsSays it can be used on dry skin, but some reviewers said that led to razor burn (so be wary before you try it that way)Why we love it: IDK if a day passes when I don't see this trimmer on my FYP. I’ve seen a gazillion videos reviewing this, calling it the best hair-removal device for way, way, way cheaper than laser or wax passes. It’s double-ended: One side is a classic blade trimmer that takes off the hair, while the other is a precision trimmer that you run along your skin in circular motions to get the closest possible trim.One Cosmo editor says: “Having the two options for trimming really helps get my skin smooth and reduces any stubble whatsoever.

Not to mention, the three comb attachments give you choices for how much hair you want to remove in each area. And don’t worry about cuts, because the rounded blade glides across your skin without getting caught.One Cosmo editor says: “I use this electric razor to trim my dad’s neck hair (sorry for blowing up your spot, Dad). But!! With that said, it proves just how simple this is to use. My dad would certainly screech in pain if I even remotely knicked him, and I never have with this (others, not so confident).”—BGAttachmentsThree guidesTrimming guide length.01mm and two larger, unspecified guidesPower sourceRechargeable batteryBattery life40 minutesWaterproof?YesAdvertisement - Continue Reading BelowProsProvides a very close trim, according to reviewersConsDoesn’t come with a wall adapterWhy we love it: My battle with ingrown hairs is essentially what led me to try a bikini trimmer in the first place. And the first one on my list was this tool from Meridian, which went viral on TikTok because it’s got a strong, sharp blade that cuts through super-thick and curly hair without causing irritation (i.e., ingrown hairs and razor burn). I usually pop on one of the two included trim guards, which keeps the length a lil longer but helps further prevent inflamed bumps.I’ll just exfoliate in the shower, rinse, then lather up a moisturizing, fragrance-free shaving cream and run the trimmer along my bikini line. I also make sure to avoid going over each area too many times to reduce irritation. Afterward, I’ll pat my skin dry and smooth on a gentle body lotion to keep my skin soft and smooth.One Cosmo editor says: "Of all of the bikini trimmers I've tested—which is a lot, btw—this is definitely the most gentle.

Say you want a super smooth, hair-free bikini line but just wanna trim everything else? Run the trimmer along your skin, then pop on the razor head to get a close shave. This tool is also really helpful on the precision front, thanks to an LED light on the head of the device that makes it way easier to get in all those little hard-to-reach crevices that you can't see super well.One Cosmo editor says: “I’ve used this tool for years, but I really fell in love when they relaunched this year. Yes, it’s expensive, but it feels fancy. The tool is weighted, but not too heavy, and made of a sturdy plastic that feels really good in my hand. And it also looks nice in my bathroom.

In those moments, I reach for this gentle Gillette Venus trimmer, which comes with a removable guard that helps me lightly trim my hair without irritation. “Using a comb attachment with a trimmer can prevent the blades from touching the skin at all, which helps avoid irritation and nicks and cuts,” says Katelyn Liston, associate scientist for Gillette Venus.One Cosmo editor says: "When I found myself suddenly en route to pool party in Miami with a bikini line I hadn't touched in months, I ran over to Target and snatched this up in a pinch.
