Which type of UV radiation causes burning, tanning, skin aging, and cancer?

UVA
UVB
UVC
Infrared

The correct answer is: UVA

UVA radiation, as mentioned in the question, is responsible for causing burning, tanning, skin aging, and cancer. UVA rays penetrate deep into the skin, causing long-term damage such as premature aging and an increased risk of skin cancer. It is important for estheticians to be aware of the harmful effects of UVA radiation and educate their clients on the importance of using broad-spectrum sunscreen to protect their skin from these damaging rays.
