What SPF is recommended for sun protection during tanning?

The recommendation for using SPF 30 for sun protection during tanning is rooted in its balance of effectiveness and practicality. SPF, or Sun Protection Factor, measures how well a sunscreen can protect skin from ultraviolet (UV) rays, specifically UVB rays that cause sunburn. An SPF of 30 blocks approximately 97% of UVB rays, making it a robust choice for individuals looking to minimize the risk of sunburn while still allowing some tanning to take place.

This level of protection is widely endorsed by dermatologists and skincare experts, as it protects the skin without completely preventing tanning. Using SPF 30 strikes a good compromise as it provides sufficient protection against potential skin damage while permitting gradual tanning. It is essential for tanning enthusiasts to consider skin type, duration of exposure, and the intensity of sunlight when selecting sunscreen, but generally, SPF 30 is a favored choice for many.
