What is a normal tan duration for a person with medium skin?

When considering the normal tan duration for a person with medium skin in a tanning bed, the correct option reflects an understanding of how skin types react to UV exposure. Medium skin typically has a balanced level of pigmentation, allowing it to tan more effectively than lighter skin types while still requiring caution not to overexpose.

The range of 15-25 minutes is appropriate as it offers sufficient time for the skin to begin producing melanin without risking the onset of sunburn. This duration effectively balances the need for effective tanning while minimizing potential skin damage.

Tanning beds are designed to emit a controlled amount of UV light, and for individuals with medium skin, this exposure is optimal for enhancing pigmentation while maintaining skin health.

Shorter durations may not yield considerable tanning results, while longer durations increase the risk of burning and negative skin reactions, which would not be advisable for skin that is not very pale. Thus, this option accurately represents the recommended tanning duration for a person with medium skin in a tanning bed.
