What is the effect of excessive moisture on acrylic nails?

Excessive moisture on acrylic nails leads to a weakening of the adhesive that holds the acrylic to the natural nail. When moisture is trapped between the acrylic and the natural nail, it can create a barrier that interferes with the curing process, preventing the adhesive from setting properly. This can ultimately result in lifting, separation, or even fungal infections beneath the acrylic. The bond becomes compromised due to the presence of moisture, making it important for nail technicians to ensure that the nail surface is clean and dry before applying acrylic enhancements.

The other options suggest positive effects of moisture on acrylic nails, which is not the case. Strengthening the bond, improving shine, and enhancing durability are all desirable features for acrylic nails but are negatively impacted by excessive moisture.
