Why is hydration important before and after tanning?

Hydration is significant before and after tanning primarily because it helps maintain skin health and minimizes irritation. When the skin is well-hydrated, it can better withstand the stress of tanning, whether it's from UV exposure in tanning beds or from sun exposure. Proper hydration supports the skin's natural barrier function, which can help prevent the dryness and flakiness that may occur after tanning.

Additionally, hydrated skin is more resilient, which can lead to fewer adverse reactions such as redness or peeling. This is important not just for comfort but also for achieving a more even and long-lasting tan, as dry and irritated skin can lead to patchiness or uneven fading of the tan.

While hydration can indeed play a role in enhancing tanning results and may influence how hydrated skin appears when applying makeup, the primary concern remains skin health and maintaining a smooth texture throughout the tanning process. Reducing body temperature is not a direct benefit of hydration relating to tanning and does not address the primary reasons for keeping the skin hydrated.
