Why Does Gel Polish Cure Under UV Light? Understanding the Science Behind It

Discover how UV light activates photoinitiators in gel polish for a speedy, durable manicure.

80 views

Gel polish dries under UV light because it contains special photoinitiators that react with UV rays. When these photoinitiators are exposed to UV light, they initiate a chemical reaction that hardens or cures the gel. This process allows the polish to set quickly and durably, giving you a long-lasting and glossy finish.
