Which of the following is essential for maintaining a good tan?

Proper hydration plays a crucial role in maintaining a good tan because it helps keep the skin healthy and vibrant. When the skin is well-hydrated, it retains moisture better, which can enhance the appearance and longevity of the tan. Hydrated skin tends to be more elastic and is less likely to peel, which can cause a tan to fade prematurely.

In contrast, high SPF sunscreen, while important for protecting the skin from UV damage, can inhibit the tanning process if applied too heavily before tanning sessions. Long tanning sessions can lead to overexposure to UV rays, increasing the risk of skin damage and reducing the quality of the tan. Daily facial scrubs, while beneficial for exfoliating dead skin and promoting cell turnover, can also lead to the removal of tanned skin if done excessively, which can diminish the overall tan.
