Which of the following is NOT a recommended practice during tanning?

Overexposing the skin is not a recommended practice during tanning because it significantly increases the risk of skin damage, including sunburn, premature aging, and a higher chance of developing skin cancer. Tanning should always be approached with caution to protect skin health.

In contrast, applying broad-spectrum sunscreen is a critical practice that helps block harmful UVA and UVB rays, thus safeguarding the skin even during tanning sessions. Exfoliating before sessions is beneficial as it helps to remove dead skin cells, leading to a more even tan and better absorption of tanning products. Following aftercare instructions is also vital as it ensures that the skin is properly cared for after tanning, which can help maintain the tan and promote skin health. Each of these practices aligns with safe tanning guidelines, while overexposure poses serious health risks, making it the only option that does not fit within recommended tanning practices.
