What post-tanning care guideline should be followed?

Avoiding water and sweating for at least 8 hours post-tanning is crucial for ensuring the longevity and effectiveness of the tan. This guideline helps prevent the premature fading of the tan, as water and sweat can lead to the breakdown of the tanning agents applied to the skin. During the initial hours after tanning, the skin is still absorbing the active ingredients that contribute to the desired color. By refraining from activities that can cause moisture or perspiration, individuals can help maintain a more even and lasting tan.

Other options do not align with the best practices for post-tanning care. For instance, exfoliation can strip the skin of its color if done too soon after tanning, and sunscreen application is recommended before sun exposure rather than immediately after tanning, as the skin is often already protected and may not need additional product at that moment. Tanning indoors, while it has its own guidelines, does not directly pertain to post-tanning care.
