Nail polish is a genuine fashion accessory that allows individuals to express their personality and add a touch of elegance to their hands. Available in an endless array of colors, finishes (matte, glossy, glitter) and formulations (classic, semi-permanent, enriched with active ingredients), it caters to every preference. However, applying nail polish requires specific techniques to ensure a uniform, long-lasting result while preserving nail health.

FAQ about nail polish

What is the typical wear duration of nail polish?

A nail lacquer exhibits an average durability of 3 to 5 days, while a semi-permanent polish can last up to 3 weeks.

Can nail polish damage your nails?

No, when properly used with a protective base coat and if the nails are regularly moisturized, the nail polish does not damage the nails. However, it is recommended to pause for about one week between consecutive polish applications.

Semi-permanent nail polish: how to remove it?

A semi-permanent nail polish is removed using a solvent specifically formulated for this application or acetone-soaked wraps. It is also possible to visit a salon to have it removed with an electric nail file that gently sands the nail.

Why doesn’t my nail polish adhere properly?

A nail polish that doesn't adhere properly may result from oily nails, a lack of base coat, or an overly thick application.

Can pregnant women safely use nail polish?

The application of nail polish is not strictly prohibited during pregnancy. However, it is recommended that pregnant women exercise caution and opt for formulas free of controversial ingredients, such as formaldehyde.

Why can nail polish cause nails to turn yellow?

Yellowing may result from dark pigments in nail polish, the absence of a protective base coat, or increased nail porosity. It is often temporary and disappears with regrowth.

What is the function of a base coat prior to nail polish application?

The base coat protects the nail from polish pigments, enhances its adhesion, and can help strengthen the nail. It also extends the durability of the manicure.

What function does the top coat serve?

The topcoat creates a protective barrier that enhances the polish’s shine and durability. It helps prevent chipping and extends the lifespan of the manicure.

Why does varnish chip off so quickly?

This may be related to poor nail preparation, the lack of a base coat, or frequent exposure to water. The quality of the polish and the application technique also play a role.

Do nail polishes have an expiration date?

Yes, like any cosmetic product, nail polish can degrade over time. A thickened consistency, a changed odor, or phase separation are signs that it’s time to discard it. Likewise, once opened, it cannot be kept indefinitely. Nail polishes carry a recommended usage period indicated by the PAO (Period After Opening) symbol, which typically spans 12 to 24 months.
