Everything you need to know about HEMA- and TPO-free gel polish
Recently, there has been a lot of talk about allergies caused by gel polish. Names like HEMA and TPO are appearing more frequently in news articles, on social media, and in product information. But what do these substances actually mean? And why are more and more brands, including LAKKIE, choosing to use HEMA- and TPO-free formulas? In this article, we explain everything clearly so that you know exactly what to look for when buying gel polish. Read on or shop HEMA- and TPO-free gel polish immediately.
What is the substance HEMA in gel polish?
HEMA stands for Hydroxyethyl Methacrylate, a chemical compound often used in traditional gel polish formulas. It is an important ingredient because it makes the gel polish flexible and ensures perfect adhesion to the nail. Although it is present in many gel polish products, it can cause allergic reactions in some people, such as redness, itching, and swelling. Sometimes they also remain sensitive to acrylates in other products, such as dental fillings or medical adhesives. This has led to the development of HEMA-free gel polish, an alternative that is suitable for people with sensitive skin types.
What is TPO?
TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is a photoinitiator, a substance that ensures gel polish cures under a UV or LED lamp.
Since September 1, 2025, TPO is no longer allowed to be used in cosmetic products within the EU because it can cause irritation or allergic reactions if used incorrectly.
That is why more and more brands are switching to TPO-free formulas, which are safer for both professionals and home users. All LAKKIE products are HEMA and TPO free.
Why can HEMA and TPO cause allergies?
When used incorrectly, for example with layers that are too thick, contact with the skin, or insufficient curing, small amounts of uncured product can come into contact with the skin. That is exactly where things go wrong: these substances can then trigger a hypersensitivity reaction.
Even with proper use, long-term exposure can lead to allergies in some people. Therefore, it is important to choose products without these ingredients. This reduces the risk of an allergy.
Are HEMA- and TPO-free gel polishes really safer?
Yes, provided they are used correctly.
HEMA- and TPO-free formulas significantly reduce the risk of allergic reactions.
That makes them a safer choice for those who use gel polish regularly, both at home and in the salon.
When working with gel polish, it is especially important to work on your nail and ensure that the gel polish does not come into contact with your skin. So do not apply polish too close to your cuticles, and let the polish cure properly under a suitable nail lamp. It is also important to work hygienically and keep your nail tools clean. If you follow these points carefully, using gel polish should not be a problem.
How do you recognize gel polish with HEMA or TPO?
Always check the ingredient list on the packaging or product page.
-
Do you see “HEMA” or “Hydroxyethyl Methacrylate”? Then the polish contains HEMA.
-
Do you see “Trimethylbenzoyl Diphenylphosphine Oxide”? Then the polish contains TPO.
If “HEMA-free” or “TPO-free” is explicitly stated, it means the formula does not contain these substances.
Is it still safe to use gel polish?
Recently, many reports have appeared about allergies and potential risks associated with gel polish. As a result, some people have become unsure whether it is still safe to use gel polish.
The new regulations are primarily aimed at making products safer and providing clear guidelines regarding ingredients such as HEMA and TPO. This does not mean that gel polish is unsafe in general, but that the composition is being better aligned with current safety standards.
Safe use remains important. Apply thin layers, avoid contact with the skin, use a suitable lamp, and always follow the product's instructions. This will help you get the best results from your gel polish and limit the risk of irritation and potential allergies.
By choosing HEMA- and TPO-free products, you also know for sure that your gel polish complies with European legislation.
Frequently asked questions about HEMA- and TPO-free gel polish
Frequently asked questions about TPO in gel polish
1. Is TPO banned in nail products?
Yes. Since September 1, 2025, TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is banned in all cosmetic products within the EU, including gel polish. This substance can therefore no longer be used in new formulas.
2. What does TPO do in gel polish?
TPO is a photoinitiator: it ensures that gel polish cures under a UV or LED lamp. The problem is that TPO can cause an allergic reaction if used incorrectly (such as contact with the skin or insufficient curing).
3. Why is TPO specifically banned?
Because studies have shown that it can cause skin irritation or hypersensitivity. The European Union has therefore decided that TPO should no longer appear in cosmetics.
4. Can I still use my old gel polish with TPO?
If you still have gel polish with TPO at home, you can in principle still use it. The substance is no longer permitted in new products because European regulations have been tightened.
5. How do I recognize if my gel polish contains TPO?
Look at the ingredient list on the bottle or product page. Is Trimethylbenzoyl Diphenylphosphine Oxide listed there? Then the product contains TPO. If you do not see it, or if the brand explicitly states “TPO-free”, then it is safe.
6. Are TPO-free gel polishes just as good as the old formulas?
Yes. Good TPO-free formulas offer the same shine, adhesion, and durability. Technology has developed to the point where you don't have to compromise on results, only the risks are reduced.
7. Can a salon still work with products containing TPO?
No. Professional salons within the EU may no longer use or sell products containing TPO as of September 1, 2025. Existing stock may also no longer be used for treatments.
8. How do I know if my current gel polish is safe?
Check the ingredient list or contact the brand. Does the brand mention nothing about HEMA or TPO? Then the polish likely contains them.
9. Which gel polish brands are completely HEMA- and TPO-free?
LAKKIE is one of the brands whose range is completely free of HEMA and TPO.
