Can you dry normal nail polish under UV light?

Can you use UV light to dry regular nail polish? No, regular nail polish requires air drying, whereas gel polish contains a polymer that must be ‘cured’ by a UV or LED lamp for it to become hard. Regular nail polishes can’t be used with UV or LED lamps and it won’t dry any quicker from being put under the lamp.

How does UV light harden gel?

In this case, ultraviolet radiation causes the photoinitiator to initiate a polymerization reaction, in which the building blocks in the solution connect to form a long polymer chain that hardens on the nail. Gel nail polish also contains pigments and stabilizers, similar to conventional nail polish.

Why does gel harden under UV?

When the photoinitiator is exposed to the proper UV light wavelength and intensity, it gives off a particle called a free radical. The free radical will initiate a polymerization reaction with the resins in the gel system.

How does UV gel dry?

Traditionally, gel nail polish is cured under UV light until it dries and becomes hardened. The gel requires UV wavelength exposure to react with compounds in the gel that absorb light and start the polymerization process.

How does gel Harden?

Gel polish is made up of acrylic oligomers and monomers, which bond together when they are placed under UV light. The process, which is known as curing, only takes a matter of seconds, turning the gel into a chemical-resistant and hard coating.

What makes gel polish Harden?

“Gel polishes are more flexible, so they stand up to chips; gels are cured under a UV or LED lamp and polishes cure in oxygen.

Can I use UV light to dry regular nail polish?

Answer. UV nail dryers are more commonly referred to as UV nail lights. The UV light being emitted by the UV lamps does nothing to dry nail polish, but the heat from the light unit itself will assist in drying nail polish.

What happens if you cure regular nail polish under UV light?

The solvent portion of nail polish evaporates over time, leaving behind the solid part that consists mostly of volatile solvents such as ethyl acetate, butyl acetate, and alcohol. The UV light from a UV Lamp or LED Lamp will not help to speed up the rate of evaporation of these solvents.

Is LED safer than UV for gel nails?

UV lamps use UV light (the kind of rays in sunlight) to also “cure” the gel polish to dry. LED bulbs are thought to be safer than UV bulbs, as they transmit weaker rays.

Is UV light necessary for gel nails?

With that in mind, you may be wondering if the UV lamps are even necessary, and the answer is yes. The UV rays help the gel polish polymerize, or harden, which is what makes the formula so durable, and dry so quickly.
