Which of the following is NOT a benefit of using acid-free primers?

Acid-free primers are specifically designed to provide a gentler alternative to traditional acid-based primers, which can be harsh on the skin and nails. The benefits of using acid-free primers include less irritation to the skin, as they lack the aggressive chemicals found in acidic products. They also enhance adherence to the enhancements without causing damage to the natural nail bed, which is crucial for nail technicians aiming to protect their clients' nails.

The correct answer highlights that acid-free primers do not have corrosive effects on natural nails, which is a significant advantage when comparing them to products that contain acids. By not causing corrosion, acid-free primers help maintain the integrity of the natural nail, making them a preferred choice among professionals seeking to prioritize client safety and nail health.

In contrast, the other options stem from the fundamental characteristics of acid-free primers. They are intended specifically to create a robust bond with enhancements and improve adhesion without compromising the client’s comfort or the condition of their natural nails.
