Semi-permanent/permanent varnish

Highly durable, permanent nail polish can last for several weeks. Semi-permanent polish is a hybrid formula between traditional nail varnish and gel, which also offers long-lasting wear without chipping. Both types of polish are cured under LED or UV lamps, which makes them very resistant. While permanent and semi-permanent polishes are appreciated for their flawless finish and longevity, they are also accused of weakening the nails. Find out more information below.

FAQ about semi-permanent/permanent varnish

How long do semi-permanent and permanent nail polishes last?

A semi-permanent nail polish lasts between two and three weeks without chipping, while a permanent nail polish can last for up to four weeks.

How to remove a semi-permanent/permanent nail polish?

A semi-permanent or permanent nail polish is removed using a strong solvent, often acetone-based, or in a salon.

How many layers of semi-permanent polish should be applied?

In general, two coats of semi-permanent polish are applied after using a base coat. The manicure is then completed by the application of a finishing polish (top coat).

Is it possible to have successive manicures with semi-permanent nail polish?

No, it is recommended to take breaks of around two weeks between each application of gel polish. In the meantime, it is beneficial to use moisturising serums or plant-based oils to strengthen the nails.

Can pregnant women use semi-permanent nail polish?

Although this is not an absolute contraindication, it is indeed not recommended for pregnant women to use semi-permanent nail polish, as it may contain substances that are problematic during pregnancy. The removal of semi-permanent nail polish, often using an acetone-based remover, is also a cause for concern.

What is the difference between permanent nail polish and semi-permanent nail polish?

Permanent nail polish is thicker, more robust, and requires mechanical removal, unlike semi-permanent nail polish, which can be taken off using a special remover.

Does gel polish damage the nails?

Yes, gel polish can damage the nails, particularly at the removal stage, when the nails may become soft or brittle.

Does permanent polish make the nail appear thicker?

Yes, the finish left by a gel polish is denser than that of a traditional nail varnish.

Before applying a permanent varnish, is it necessary to buff the nails?

Yes, this is recommended because a slight roughness promotes the adhesion of the gel polish.

Should you let your nails breathe between two applications?
