What is a benefit of using broad-spectrum SPF while tanning?

Using broad-spectrum SPF while tanning is beneficial because it provides protection against both UVA and UVB rays. UVA rays penetrate the skin more deeply and are primarily responsible for premature skin aging and tanning, while UVB rays are the main cause of sunburn. A broad-spectrum sunscreen allows for tanning to occur while significantly reducing the risk of UV damage, such as sunburn and skin cancer.

By allowing for controlled tanning, broad-spectrum SPF enables individuals to enjoy sun exposure while minimizing negative skin effects. This is particularly important for those who may be tanning intentionally but want to protect their skin health at the same time.
