What is a key step in preparing for tanning?

The correct answer emphasizes the importance of exfoliating and moisturizing the skin as a key step in preparing for tanning. Exfoliating removes dead skin cells, which can lead to a more even and smooth application of tanning products. This helps ensure that the tan will develop evenly and last longer. Additionally, moisturizing is crucial as it hydrates the skin, creating a better surface for the tanning solution to adhere to. Dry or flaking skin can lead to uneven tanning results and potentially patchy areas.

In contrast, options like focusing solely on applying sunscreen neglect the need for proper preparation of the skin. While sunscreen protects the skin from harmful UV rays, it does not address the texture or moisture level of the skin before tanning. Similarly, moisturizing dry areas only does not provide the full benefit that a comprehensive skincare routine would offer; it's important to apply moisturizer evenly over the entire body. Lastly, shaving without moisturizing can lead to irritation and roughness, which are detrimental to achieving a smooth and flawless tan. Therefore, exfoliating and moisturizing adequately prepares the skin, ensuring optimal results from the tanning process.
