Curious if gel nails might harm your natural nails? Discover the potential risks, from brittleness to chemical exposure, and learn how to keep your nails healthy while enjoying the long-lasting shine of gel manicures.
Nails are the ultimate accessory. From French manicures to glittery nail art, your fingers can certainly make a statement. Want amanicurewith staying power? Gels can last up to 3 weeks and provide a glossy finish without chipping or peeling.

Plus, the durable gel means you can wash dishes without worrying about ruining your nail job…. but could it be ruining your natural nails? And can nail gels affect your overall health? Here’s what you need to know.
Is gel bad for your nails?
This largely depends how you use it. Gel polish can be tough on the surface of your natural nails. But occasionally getting this type of nail polish applied and removed by licensed professionals isn’t likely to have any long-term adverse effects on your nail health.
Just watch out for these signs ofdamageon or around your nails:
Is gel bad for your nails? Let’s check the research
One of the most extensive studies to date looking at the side effects of gel nail polish took place in asurvey, involving 2,118 respondents. In the self-reported questionnaire, almost half reported side effects while applying the gel nail polish, and 1 in 5 while wearing it.
Potential side effects during the application or wearing gel nail polish include:
Less than 1 percent of folks reported a rash on their hands or body,eczema, or swollen lips.
Gel removal is the most likely stage to cause damage
The study above also found that 3 in 4 people experienced side effects afterremoving their gel manicure, including:
But not all removal methods were as likely to cause probs. The study found that these side effects were far more likely to happen when participants performed (and removed) the manicure themselves.
Is gel bad for your health? Let’s look at the chemicals
One of the first things that usually hits you when you walk into a nail salon is the strong chemical smell. Not all of these substances are necessarily harmful, but many gel polishes can contain some potential nasties like:
There’s still some debate about whether these chemicals are considered toxic, but formaldehyde is particularly concerning. TheEnvironmental Protection Agencysays that research associated it with certain cancers, and it can also causecontact dermatitis, especially if you have sensitive skin.
What these chemicals mean for your health
Some research even suggests that some chemicals in nail polish can leach into your body.
In asmall 2015 study, researchers tested the pee of 26 women who had recently painted their nails. Compared to placebo manicures wearing gloves and fake nails, TPHP levels increased sharply in every participant in the active nail painting group. Remember, TPHP is an endocrine-disruptor, which means it messes with your hormones.
Are these harsh chemicals avoidable?
If you’re concerned about the chemicals in your gel polish, you can look for potentially less toxic alternatives. Check the packaging for labels like 3-, 5-, or 10-free, meaning they’ve eradicated that number of harsh chemicals.
For example, 3-free means the company claims their formula is free of formaldehyde, toluene, and dibutyl phthalate. (Most brands are currently 3-free.)
But theDepartment of Toxic Substances Controltested consumer nail products and found that many 3-free products actually contained toluene, dibutyl phthalate, or both. Plus, keep in mind that removing a handful of toxic chemicals doesn’t guarantee the remaining ingredients are safe.
Are LED nail lamps safe?
After your nails get a coat of gel paint, they’ll bask in the glow of an LED nail lamp to harden and set.
The LED bulbs emit ultraviolet (UV) radiation — but thinksunlightrather than Chernobyl. Over time, exposure to UV radiation candamage your skin,leading to premature wrinkles and age spots, and could even lead to skin cancer.
But a2013 studysuggested that the limited exposure you’d get at a nail salon isn’t a big deal. These LED nail lamps are generally considered low risk by theFDAas long as they’re used as directed.
FYI: If you’re more sensitive to UV radiation (because of a condition or medication, for example) you may want to pass on this exposure.
What to expect during a gel nail appointment
Gel nails typically take a little longer than a regular manicure. You can expect to spend about an hour, but it does depend on the state of your nails and if you’re already wearing gel polish when you arrive.
Step 1. Nail prep
First, your manicurist will prep your nails. They’ll push back your cuticles with a hand sanitizing product to keep the nails from absorbing oils. (Yes,oil is goodfor your cuticles, but save it for after the manicure.)
Next, they’ll trim away any excess cuticle, and shape your nails. Then, they’ll cleanse your nail bed with alcohol and a product to balance the pH to ensure that gel sticks.
Step 2. Base gel
The base gel is a base coat that helps the real deal gel stick to your nails. This also prevents the pigments in the gel from staining your nail beds (which is never a great look). You’ll then pop your nails under the nail lamp for around 15 seconds, depending on the manufacturer’s instructions.
Step 3. Topcoats
Now for the good stuff. Usually, you’ll have two coats of color applied, with a cure of 30 seconds under the nail lamp for each.
Then, you’ll get a topcoat applied to keep the color looking slick and shiny. Again, this will be cured under the lamp.
Most gel polishes leave a sticky dispersion layer behind after curing, which your nail tech will wipe away with alcohol.
Step 4. Cuticle oil
Ooh! Look at those nails shining like no one’s business! At this point, your nails are complete and shinier than a new car. But before you leave, your manicurist will apply a layer of cuticle oil to keep them looking tip-top.
Common gel mistakes to avoid
Fresh gels look sexy AF, but how do you keep them that way? Here are some things to avoid when you’re rocking gel nails to keep your natural nail as healthy as possible.
Less damaging alternatives
Although it’s not as on-trend and certainly not as durable, traditional nail polish still does the job. In addition, there are tons of new products entering the market with long-lasting formulas designed as a hybrid between classic and gel polish.
If you want a fresh looking manicure for an event, there are always press-on nails to fall back on. Gone are the days of thick, plastic-looking extensions that wouldn’t fool anyone. Nowadays, press-on nails look realistic, come in various designs, and can even last up to a week. And providing you don’t lose any, you can reuse them. Plus, they’re a great option fornail biters.
Gel nails are safe for most people, especially if you save them for special occasions when you and your nails need to shine.
Look for nontoxic products if you can, as nail polish, including gel, can include chemical nasties.
Also, if you go overboard on the mani-pedis, your nails can become dry, brittle, and broken. So, if you want your nails looking on-fleek at all times, consider using classic polish or press-on nails in between gel manicures.
