What is the role of exfoliation in spray tanning?

Exfoliation plays a crucial role in preparing the skin for spray tanning by removing dead skin cells, which helps create a smoother and more even surface for the tanning solution. When the top layer of dead skin is exfoliated, it not only allows for a more uniform application of the tanning product but also contributes to better absorption of the tanning solution, resulting in a more natural and longer-lasting tan. Smooth skin ensures that the tanning solution adheres properly and minimizes the risk of streaks or patches that can occur when applying the product over uneven or flaky skin.

Options that involve removing excess moisture, enhancing melanin production, or adding color pigments do not specifically address the primary function of exfoliation within the context of spray tanning; these processes are unrelated to creating an optimal base for an even tan.
