In what scenario should a technician use a barrier cream?

The use of a barrier cream is particularly important for protecting the skin from harsh chemicals that are commonly encountered in nail services. These chemicals can include those found in products like nail polish remover, acrylics, and other solvents that can lead to dryness, irritation, or allergic reactions. By applying a barrier cream, technicians can create a protective layer on the skin, thus minimizing the risk of harmful exposure.

While other scenarios, such as applying nail polish or using acrylics, involve some level of skin contact with potentially harmful substances, the primary purpose of barrier creams is to provide a protective barrier specifically against these harsh chemicals. Preparing nails for buffing does not typically involve exposure to harmful substances, making the application of barrier cream unnecessary in that context.
