Nail polish has been around for centuries, but the acrylic nail took off in the 1970s. Acrylic nails are made of a mixture of liquid monomer and polymer powder. When these two substances are combined, they create a hard plastic that can be molded to any shape.
Acrylic nails need to be cured under a UV light in order to harden. The UV light helps to speed up the curing process and ensures that the nails are properly hardened. Without this step, the acrylic nails would not be as strong or durable.
So, in answer to the question, “Do acrylic nails need UV light?”, the answer is yes! UV light is necessary in order to cure the nails and ensure that they are properly hardened.
In this post, we’ll provide more information on why UV light is necessary for curing acrylic nails. We’ll also give you some tips on how to properly cure your nails under a UV light.
Let’s get started!

Do Acrylic Nails Need UV Light?
In a nutshell, yes! Acrylic nails must be cured in the presence of UV light. The nails would not be as robust or durable if they were not treated with UV light.
A UV nail lamp is a fantastic option for curing acrylic nails if you’re searching for a quick, cost-effective, and easy method to mend them. Simply follow the instructions that came with your lamp to get on your way to gorgeous, strong, and disease-free nails.
What is the Role of UV Light in Curing Acrylic Nails?
As we mentioned above, UV light plays a crucial role in the curing process of acrylic nails. Without UV light, the acrylic nails would not be as strong or durable.
When you apply the acrylic mixture to your nails, it will start to harden immediately. However, this initial hardening is not enough to create a strong and durable bond. In order for the nails to be properly cured, they need to be exposed to UV light.
The UV light helps to speed up the curing process and ensures that the nails are properly hardened. Without this step, the acrylic nails would not be as strong or durable.

Why UV Light is Essential for Curing Acrylic Nails
When you hear the term “curing,” it might make you think of hardening, like when you’re waiting for your food to cook or your paint to dry. In the context of acrylic nails, curing refers to the process of polymerization.
Polymerization is a chemical reaction that creates long chains of molecules, known as polymers. These polymers are what give the acrylic nails their strength and durability.
UV light helps to speed up the polymerization process, so that the nails cure quickly and evenly. If you were to try to cure your nails without UV light, it would take much longer for the nails to harden properly.
Not only does UV light speed up the curing process, but it also helps to ensure that the nails are cured evenly. If some parts of the nails are not exposed to UV light, they will not cure properly and could be weak or brittle.
Why Should You Use a UV Nail Lamp?
There are a few different ways that you can cure your acrylic nails. One option is to use a UV nail lamp.
A UV nail lamp is a specialized piece of equipment that emits UV light. This light helps to cure the nails and ensure that they are properly hardened.
