How does skin hydration affect the longevity of a tan?

Better-hydrated skin retains its tan longer because hydration plays a crucial role in maintaining the skin's elasticity and overall health. Well-hydrated skin is less likely to flake or exfoliate quickly, which is a common process that leads to the fading of a tan. When the skin is moisturized, it provides a smoother surface and enhances the appearance of the tan, allowing it to stay intact for a more extended period.

Additionally, proper hydration supports the skin’s natural barrier function, which can help in holding onto the tan. Dehydrated skin is prone to dryness and peeling, accelerating the loss of color. Therefore, maintaining adequate skin hydration is essential for prolonging the longevity and vibrancy of a suntan.
