What is the primary purpose of exfoliation in manicure services?

The primary purpose of exfoliation in manicure services is to soften and renew the skin. During the exfoliation process, dead skin cells are sloughed off, which helps to reveal fresher, smoother skin underneath. This not only improves the appearance of the hands but also enhances the overall texture and feel of the skin. Exfoliating can prepare the skin for subsequent treatments, such as moisturizing and massage, making these services more effective.

While removing old nail polish is an important step in the manicure process, it does not address skin rejuvenation. Enhancing nail color pertains to the application of nail polish, not skin care. Promoting nail growth is also not directly related to exfoliation; rather, it focuses more on overall nail health and care practices. Thus, the significance of exfoliation is rooted in its ability to refresh and rejuvenate the skin, making option B the correct choice.
