Nail polish or gel polish: which is right for you

Regular nail polish is a lacquer of nitrocellulose and resins in a solvent that dries in the air. Gel polish is a liquid of acrylate monomers and a photoinitiator that stays soft until a lamp turns it into a hard plastic film. The two look alike in the bottle and behave differently in every way that matters: how long they last, how they come off, what they do to the nail and what they cost.

Since 2025 the choice has a legal side too. The EU has banned the most common gel photoinitiator, TPO, and restricts the monomer HEMA to professionals. Regular lacquer is untouched by both rules, because it contains neither.

What is the difference between gel polish and regular polish?

Regular polish is a film of nitrocellulose, resins, plasticisers and pigment dissolved in solvents such as butyl acetate and ethyl acetate. It dries as the solvent evaporates, from the bottom up, and is touch-dry in about 3 to 5 minutes but takes hours to harden fully (Nagelstudios.nl). Nothing happens to it under a lamp.

Gel polish is a mixture of methacrylate and acrylate monomers and oligomers with a photoinitiator. Light from a lamp at 365 to 405 nm triggers polymerisation, and the liquid becomes a hard, cross-linked film in 30 to 60 seconds. There is no dry time, the gloss is high and the film resists chips, which is why salons and at-home kits have grown so fast (Etos).

Between the two are gel-effect lacquers: air-dry polishes with a thick, high-solids top coat that cure by light and air. Sally Hansen Miracle Gel claims up to 14 days and removes with ordinary remover (Sally Hansen). Independent testers typically report 5 to 10 days from these systems.

How long does each one last?

Gel polish wears 2 to 3 weeks on fingernails and 6 to 8 weeks on toenails, where the nail grows at about half the speed (Etos). The limit is growth, not chipping: the gap at the cuticle is what ends a gel manicure.

Regular polish wears 3 to 7 days depending on preparation and top coat. The main wear tips are a degreased nail, thin coats, a capped free edge, a glossy top coat refreshed every 2 to 3 days, and gloves for hot water. A well-prepared regular manicure reaches a week; a rushed one chips in two days.

How is each one removed?

Regular polish comes off in a minute with acetone or an acetone-free remover on a cotton pad. Acetone is faster and dries the plate and skin more; both are followed by hand cream or cuticle oil.

Gel polish needs the surface filed to break the seal, then cotton soaked in acetone wrapped on each nail in foil for 10 to 15 minutes, then a gentle lift with a wooden or plastic stick. Peeling gel off the nail takes the top of the nail plate with it, leaving white spots, grooves and thinning that take months to grow out (Cleveland Clinic). Some at-home gels are designed to release faster: Manucurist Green Flash claims removal with acetone-free remover in about a minute (Manucurist).

Which is better for nail health?

Regular polish, on three counts. First, removal: a solvent wipe takes far less from the nail plate than filing and a 10 to 15 minute acetone soak every two to three weeks. Second, allergy: gel monomers, especially hydroxyethyl methacrylate (HEMA), can cause contact dermatitis around the nail and, less often, hives (Cleveland Clinic). Third, light: gel needs a UVA lamp, and the Cleveland Clinic's view is that no risk-free nail lamp exists and that the cancer risk from cumulative exposure is low but present. Its dermatologist Dr Chey Ranasinghe suggests limiting gel to a few times a year (Cleveland Clinic).

The EU has acted on the allergy point. Commission Regulation (EU) 2020/1682 restricts HEMA and Di-HEMA trimethylhexyl dicarbamate to professional use only, with a label stating professional use only and a warning that it can cause an allergic reaction, applicable from 3 June 2021. A 2024 market survey found widespread non-compliance in gel sold online to consumers (Scratch). Any at-home gel sold in the EU should be HEMA-free and say so.

None of this makes regular polish a treatment. Solvents dry the nail, dark pigments stain it without a base coat, and a nail that is never bare misses the daily oil it needs. The healthiest routine is regular polish with a base coat, cuticle oil twice a day and a bare week now and then.

What does the EU TPO ban mean for gel polish?

TPO (trimethylbenzoyl diphenylphosphine oxide) is the photoinitiator that made gel cure fast under a lamp. The EU classified it as a category 1B reproductive toxicant on animal data, added it to Annex II of the Cosmetics Regulation and prohibited it from 1 September 2025 in all 27 member states plus Norway and Switzerland, with no sell-through period (Cosmetics Business). Gel bought in a salon or a shop in the EU since that date is formulated with replacement initiators such as TPO-L, and "TPO-free" is now a standard label claim.

Great Britain followed with its own dates: TPO products may not be placed on the market after 15 August 2026 and may not be sold through after 14 February 2027 (Scratch). The United States has no equivalent restriction, so gel bought online from outside Europe may still contain TPO.

TPO is irrelevant to regular polish. A solvent lacquer has no photoinitiator because nothing in it cures by light. The same is true of HEMA. A lamp-free lacquer such as the India Anaïs cat-eye Nebula avoids both rules by design; the first edition is sold out and the next edition is planned for spring 2027.

What does each one cost?

Regular polish costs about $10 for a 13.5 ml Essie or $34 for a 13 ml Chanel, plus a base and a top coat, and nothing else. At-home gel costs less per bottle in some brands but needs a lamp: Manucurist Green Flash gel is €19 a shade, with lamp kits from €49 to €165 (Manucurist).

The running cost of gel is time and acetone: every removal is a filing and soaking session, every reapplication a session under the lamp. The running cost of regular polish is a fresh top coat every few days.

Gel polish and regular polish compared

Who should choose which?

Choose gel for a holiday, a wedding, a job where hands take a beating, or a signature shade you never change. Choose regular polish if you like to change colour, if your nails are thin, peeling or ridged, if you have ever reacted to a gel or an adhesive, or if you would rather skip the lamp. Toes are the one place where gel wins on most counts, because the nail grows slowly and the removal is rare.

You will need, to move from gel back to regular polish without damage: acetone, cotton, foil, a wooden stick, a 240-grit buffer, cuticle oil, a base coat and your colour.

1. Remove the last gel set with the foil method. Never peel it.
2. Buff the plate lightly to smooth any ridges, with nothing coarser than 240 grit.
3. Oil the cuticles and nails twice a day for a week, and keep the nails short while the thinned plate grows out.
4. Apply a base coat before every colour to protect the plate and stop staining.
5. Paint two thin coats and a top coat, capping the free edge, and refresh the top coat every 2 to 3 days.
6. Expect the full plate to take about six months to replace itself, so the last of the gel damage grows out over that time.
