HEMA and TPO-Free Gel Manicure: Why It's Essential for Your Nails
What is HEMA and why are we hearing about it?
HEMA — or hydroxyethyl methacrylate — is a chemical compound that has been used for years in nail gels, semi-permanent polishes, and extensions. It's what allows the gel to adhere strongly to the nail. Long considered indispensable, it is now at the heart of a real beauty controversy.
Why? Because HEMA is one of the most powerful contact allergens found in cosmetic products. According to the European Society of Contact Dermatitis, cases of methacrylate allergies increased by more than 30% between 2018 and 2024. Once sensitized, a person can react for life — not only to nail products, but also to certain dental and medical materials containing similar compounds.
Symptoms of a HEMA allergy
A HEMA allergy doesn't always manifest immediately. Sometimes it develops after months or years of regular use. Signs to look out for:
- Redness and swelling around the nails
- Intense itching on fingers or eyelids
- Peeling skin around the cuticles
- Nails that lift or become brittle
- In severe cases: generalized reaction
The major problem: once sensitization is established, it is irreversible. This is why prevention is infinitely better than cure.
TPO — another substance now banned
HEMA is not the only culprit. TPO (diphenyl trimethylbenzoyl phosphine oxide) was also widely used as a photoinitiator in UV gels. Classified as a Category 1B CMR substance — meaning toxic for reproduction — it has been officially banned in France and throughout the European Union since September 1, 2025 by the DGCCRF.
This ban applies to all cosmetic products, including professional gels used in salons. Brands that had not anticipated this regulation had to reformulate urgently.
The Care Gel: HEMA-free and TPO-free from day one
At The Care Gel, we made this choice from the brand's inception — not out of obligation, but out of conviction. Our gel nail patches are formulated without HEMA, TPO, parabens, and phthalates. Fully vegan and cruelty-free.
This is not a marketing argument. It is a guideline that directs every formulation decision. Because we believe that a beautiful manicure should never come at the expense of your health.
How to know if a product contains HEMA?
On labels and product sheets, HEMA may appear under different names:
- HEMA (common abbreviation)
- Hydroxyethyl Methacrylate (official INCI name)
- 2-Hydroxyethyl methacrylate
The advice: always read the INCI list before buying a nail gel. If you see any of these terms and have sensitive skin or a history of allergies, opt for a methacrylate-free formula.
HEMA-free manicure: does it last as well?
This is the question everyone asks. And the answer is yes — provided you choose the right formula.
The Care Gel patches last up to 3 weeks without HEMA or TPO. How? Thanks to a formula that uses alternative adhesives and photoinitiators, carefully tested to offer the same performance without the allergic risks. Our customers note a solid hold against dishwashing, sports, and daily life.

In summary: what you need to remember
HEMA and TPO are two substances whose risks the nail industry is only just beginning to grasp. TPO is now banned. HEMA is under increasing scrutiny. Choosing a formula without these substances means investing in the long-term health of your nails.
At The Care Gel, this choice is made for you — from the very first application.
