When it comes to nail products, most of us focus on the color, shine, or how long a set will last. But what about the ingredients inside those bottles? If you’ve ever scanned a label and spotted names like HEMA or TPO and thought, “What even is that?”— you’re not alone. These are common ingredients in many gels and nail systems, but not everyone knows what they actually do or why skipping them can sometimes be the smarter choice.

What is HEMA?

HEMA (short for 2-Hydroxyethyl Methacrylate) is a monomer used in many gel and acrylic products. Its main role? Helping formulas stick and stay strong. That’s why it’s so popular in the nail world; it makes nails feel durable and long-lasting. The downside is that HEMA can also be a common allergen. Frequent exposure, especially for nail techs who handle it daily, can sometimes lead to skin irritation, sensitivity, or even allergic reactions. Once this allergy is developed, it tends to stick around, making it difficult to use any product containing HEMA without discomfort.

What is TPO?

TPO(short for Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) is a photoinitiator, which means it helps gel products cure properly under UV/LED light. It ensures that the gel hardens evenly and stays put. Like HEMA, TPO can also cause irritation and allergic responses for some people. It’s not harmful to everyone, but for those with sensitivities, it can be uncomfortable. For pros, repeated exposure only increases the risk.

Why Go HEMA-Free & TPO-Free?

The good news is: nail products don’t need HEMA or TPO to be effective. Modern, innovative formulas can deliver the same strength, wear time, and flawless finish without relying on these ingredients.

By choosing HEMA-free and TPO-free formulas, you’re choosing:

• Less risk of irritation and allergic reactions

• Safer, more comfortable products for nail techs who work with gels all day

• More inclusive options for clients with ingredient sensitivities 

• Long-term nail health without sacrificing results

In other words, it’s about keeping your nails and your experience, as healthy, comfortable, and enjoyable as possible. 

Strong, Safe, and Still Stunning

Some people worry that if a formula is “free-from,” that is must also be “less-than.” That couldn’t be further from the truth. Today’s HEMA-free and TPO-free formulas are designed to perform just as well, if not better, than their traditional counterparts. You can count on long-lasting wear, strong adhesion, and gorgeous shine, all without the worry,

Knowledge is Self-Care

Ingredient awareness isn’t just for skincare labels. Understanding what’s in your nail products is self-care, too. By making the switch to HEMA-free and TPO-free formulas, you’re not just keeping your nails looking amazing; you’re also making a smart, healthier choice for yourself, clients, and your long-term nail journey. 

The Choice is Yours

The next time you pick up a gel bottle or book a service, remember: beautiful nails should never come at the cost of your comfort or health. Choosing HEMA-free and TPO-free products means choosing strength, safety, and inclusivity.
