As I was scrolling TikTok on the hunt for nail trends, I came across a post that required a deep dive. It was on the topic of MMA nails—which yes, just like everyone else I was thinking “Mixed Martial Arts?” Seeing that this post actually had nothing to do with that and instead the health of your nails, I was curious.
Acrylics have long been a popular go-to when it comes to getting your nails done and have made the rounds recently again— but a dangerous chemical called MMA (Methyl Methacrylate) could be putting your nail health (and overall health) at serious risk.
Originally designed for industrial use and medical applications like dental prosthetics, MMA is too harsh for cosmetic use — yet some salons still illegally use it for nail applications because it's cheap and durable.
However, having your nails done should be a fun, relaxing experience, not a hidden danger to your health. So if your salon is using a chemical called MMA (Methyl Methacrylate), you could be putting your natural nails (and more) at serious risk. Here's why you should steer clear and how to arm your nails instead.
What Is MMA, and Why Is It Harmful?

MMA hardens into a rock-solid acrylic that doesn’t flex with your natural nail. This can cause:
- Severe nail damage: The natural nail can tear away from the nail bed during impact.
- Painful skin reactions: Redness, swelling, itching, and burning are common.
- Respiratory issues: Fumes can cause dizziness, headaches, and breathing problems.
- Difficult removal: MMA nails often require aggressive filing, thinning and damaging the natural nail underneath.
Due to these serious risks, the FDA discourages MMA use in nail salons, and many states have banned it for cosmetic purposes.
How to Tell If a Salon Uses MMA
Protect yourself by watching for these red flags:
- A strong, harsh chemical smell that’s different from typical acrylic odors.
- Very low prices for full sets or fills — MMA is cheaper than safer alternatives.
- Rough, aggressive filing of your natural nail before the acrylic is applied.
- Hard, brittle nails that feel inflexible and unnatural.
- Painful or damaging removal, even after soaking in acetone.
What Products Should Be Used Instead?
Look for salons that use EMA (Ethyl Methacrylate) — the safe, industry-approved alternative. EMA is gentler, flexible, and much safer for your nail health.
Other healthy options include:
- Gel extensions
- Dip powder nails
- Builder gel overlays
These methods are less aggressive on your natural nails and easier to remove safely.
Tips for Keeping Your Nails Healthy
Even with safe products, good nail habits make all the difference.
- Moisturize your nails and cuticles daily.
- File gently with a fine-grit file.
- Always soak off enhancements — never rip or peel them.
- Take breaks between sets to let your nails recover.
- Eat a nutrient-rich diet to support strong, healthy nails.
Your nails are more than just a canvas for color — they’re a crucial part of your overall health and damage to them can last much longer than your manicure. When in doubt, ask questions at the salon and trust your instincts. If something doesn’t feel right, it’s okay to walk away — your nails will thank you!
