Present in most traditional manicure routines, acetone is the most widely used nail remover in the world – yet one of the least understood. It is applied habitually, without fully considering its impact on nail keratin or skin. Between undeniable effectiveness on gels and semi-permanents on one hand, and drying risks on the other, the verdict is mixed. It’s time to take stock of this particular solvent, what the risks of using it are, and how to avoid it.
What is acetone and what is it used for?
Acetone is an organic solvent from the ketone family, naturally present in the body in small amounts and produced industrially on a large scale. Colorless and with a characteristic odor, it is one of the most effective removers on the beauty market. Its main cosmetic application is nail polish removal, but it is also used in some household products to dissolve, degrease, and clean.
Why does acetone dissolve polish?
Nail polish is made of film-forming polymers (nitrocellulose, resins, plasticizers) which, when dry, form a rigid film. Acetone works by breaking the intermolecular bonds of these polymers: it breaks them down and makes them soluble, allowing the polish to be removed in seconds. This is what makes it so effective on the most resistant formulas.
When to use it: regular polish, gel, tips
For regular polish, acetone is not essential; a gentle remover may suffice. However, it becomes indispensable for removing semi-permanent or gel polish, whose polymer structure is very dense and impermeable to light solvents. It is also necessary to remove gel or acrylic tips and false nails, often applied with glues or resins that only acetone can truly soften. Its use should therefore be reserved for situations where gentler alternatives prove insufficient.

Is acetone dangerous for nails and skin?
Acetone is not classified as a CMR substance (carcinogenic, mutagenic, reprotoxic). When used occasionally and externally, there is no significant absorption through the skin. However, if you use it frequently, its intense drying power can become a real risk for nails and skin. Especially if you suffer from chronic dermatological issues (such as eczema or psoriasis) or if your nails are already soft or damaged.
The effects of acetone on nails: dryness, structural fragility, breakage
By dissolving the polish, acetone also destroys the lipids contained in keratin. Without this protective oily film, the nail loses its natural defenses and is at great risk: dehydration and matrix function disorders. Keratin production is impaired, and nails tend to become dull, soft, brittle, or ridged. These warning signs indicate it is urgent to change your manicure routine and provide your nails with the necessary care to regain beautiful, strong, and radiant nails.
The effects of acetone on the skin: a risk of irritation?
The same applies to the cuticles, those small skins surrounding the nail plate. Acetone dissolves the protective hydrolipid film, causing a
How often can acetone use pose a risk?
Hard to say because it depends on the initial condition of the nails and skin. Generally, the more you chain polish applications and removals without intermediate care, the less the nail can regenerate, and the risk of chronic fragility increases.
👉 We often tell you: it is essential to adopt a sustainable manicure routine by using nail-friendly products and including breaks and nail care between polish applications.
Aggressive and frequent polish removals weaken nails and cuticles over time.
With or without acetone, how to remove polish or gel without damaging your nails?
How to use acetone to remove traditional gel or semi-permanent polish?
The most effective and least damaging acetone removal method is to matte the top layer of the gel with a fine-grit file or buffing block, without reaching the natural nail. The goal? To allow the acetone to penetrate the polish layers for better dissolution.
Then soak cotton pads with pure acetone and place them on each nail, then wrap the fingertip in aluminum foil to keep it in contact. After ten to fifteen minutes, lift the gel with a wooden stick, without forcing.
⚠️Do not scrape off residues, as you risk damaging the keratin layers. If gel residues persist, reapply acetone.
A few simple steps can significantly reduce the impact of acetone:
- Protect the skin around the nails with a rich cream or petroleum jelly before application.
- Work in a well-ventilated area: at high concentration, acetone vapors can irritate the respiratory tract.
- Do not exceed the recommended application time, to avoid worsening dryness without added benefit.
- Apply a cuticle oil immediately after removal to compensate for lipid loss.
When using acetone, prevent nail and cuticle dryness.
Gentle acetone-free removers: are they really effective?
Acetone-free removers mainly rely on alternative solvents like ethyl acetate. Their strength: they are less aggressive to the keratin lipids than acetone, better preserving the nail’s flexibility and hydration. Many formulas also include vegetable oils to offset the drying effect inherent to any solvent.
Their real effectiveness depends, however, on the type of polish to be removed:
✅ On a classic polish without gel finish, with a slightly longer application time than with acetone.
❌ On a traditional semi-permanent polish, UV gel, or acrylic resin.
✅ On bio-sourced polish formulas such as Green™ nail polishes and Manucurist’s Green Flash™ semi-permanent polishes. Thanks to their mostly natural origin composition, these next-generation polishes avoid aggressive removal methods like acetone and filing that weaken nails.
With Green Flash™, discover the pleasure of peel-off polish removal.
The Dissolvant Green Flash™, 96.5% bio-sourced, acetone-free and enriched with castor oil, gently removes all Manucurist polishes in just 1 minute (10 minutes for the Xtrem Flash™ Top Coat), while hydrating the nail plate. Result: a perfectly preserved natural nail, with no signs of damage or dryness.

How to repair nails sensitized by acetone?
Care products to prioritize for nourishing the nail and cuticles
Nails that have undergone repeated acetone polish removals are often dehydrated. The priority is therefore to restore their lipid and water balance. For this, a restorative routine combining Base S.O.S. and Masque S.O.S. allows deep rehydration and revitalization of the cuticles in 2 weeks.
At the beginning of each week, file and mattify your nails using a fine-grain file and a buffing block. Then apply the Base S.O.S. every 2 days without removing makeup. At the end of the week, remove the successive layers with a little gentle remover and apply the Masque S.O.S. before bed, leaving it on all night. Remove it by peeling off the next morning or with a little soapy water if the film does not come off by itself.
Treatments containing nourishing vegetable oils, plant-based keratin, biotin, or vitamins C and E also support the regeneration of nails and cuticles. You can therefore add complementary treatments to your repair regimen such as:
- The Green Oil, to be applied daily with a massage on the nails and cuticles.
- The Keratin Booster, to be applied 1 to 3 times a day for 7 days, allowing it to dry until the product is fully absorbed.
- The Perfecting Concentrate, to be applied as needed for intense and continuous hydration.
Acetone is not a trivial product and should be used with caution. The key is to adopt the right habits, namely:
👉 use it only when really necessary, to remove gel or acrylic false nails or semi-permanent polish,
👉 not too often to limit drying effects,
👉 adopt a gentle manicure routine that respects nail health.
