What are clients advised to do before tanning to improve results?

Participating in professional exfoliation treatments before tanning is highly beneficial for clients aiming to enhance their tanning results. Exfoliation helps remove dead skin cells from the surface, allowing for a more even and longer-lasting tan. When the skin is properly exfoliated, it creates a smooth canvas that enables the tanning solution – whether it's from a spray tan or UV tanning – to adhere better and penetrate more evenly.

In terms of the other options, while bronzers and tanning oils may enhance appearance or simulate a tan, they don't directly contribute to the tanning process itself. Indoor workouts, while promoting overall health, do not specifically address skin preparation for tanning. Eating a high-protein diet can be important for skin health but is not directly linked to improving tanning results. Therefore, exfoliation stands out as the most effective strategy for ensuring an optimal tanning experience.
