What is one purpose of using a primer before applying UV gel?

Using a primer before applying UV gel serves the crucial purpose of improving adhesion. Primers create a stronger bond between the natural nail and the gel, which is essential for the longevity and durability of the nail enhancement. They help to create a suitable surface for the gel to adhere to, reducing the risk of lifting or chipping. This strong adhesion is vital for ensuring that the gel lasts for the intended duration without causing damage to the natural nail.

While color enhancement, hydration, and decreasing drying time are important factors in nail technology, they do not specifically relate to the primary function of a primer in this context. Primers are not designed to add color or hydration, nor do they affect drying times directly; those functions are associated with other products in the nail application process. This makes improving adhesion the key purpose of using a primer prior to applying UV gel.
