Question: 1 / 400

What are the two types of ultraviolet radiation?

UVA and UVC

UVA and UVB

The two types of ultraviolet radiation that are most commonly discussed in the context of skin care and esthetics are UVA and UVB. UVA rays can penetrate deep into the skin and are primarily responsible for aging effects, such as wrinkles and sun spots, as well as being linked to some skin cancers. UVB rays, on the other hand, are primarily associated with causing sunburn and also contribute to the development of skin cancer. Both types of UV radiation have significant implications for skin health, and protective measures, such as sunscreen that filters both UVA and UVB, are essential for preventing skin damage.

While other combinations of UV types are mentioned, such as UVC, which is largely absorbed by the earth's atmosphere and does not typically reach the skin, they are not the primary focus in skincare practices. Thus, UVA and UVB are the correct answers when discussing the types of ultraviolet radiation relevant to esthetics and skin protection.
