Question: 1 / 400

Name the two types of UV radiation.

UVA and UVC

UVA and UVB

The two primary types of UV radiation relevant in the context of esthetics and skincare are UVA and UVB. UVA rays penetrate the skin more deeply and are primarily responsible for skin aging, including wrinkles and photoaging. They can penetrate through windows and are associated with the development of skin cancer as well. On the other hand, UVB rays are primarily responsible for sunburn and play a significant role in the development of skin cancer as well. They are more intense but do not penetrate the skin as deeply as UVA rays.

Using this knowledge is crucial in esthetics practices for protecting the skin from damage caused by UV radiation, as both types can have detrimental effects on skin health over time. Therefore, recognizing UVA and UVB as the two types of UV radiation is essential for anyone working in the field of skincare.
