How does UVB radiation affect the skin?

UVB radiation is known for its significant effects on the skin, primarily causing sunburn and contributing to the development of skin cancer. When UVB rays penetrate the skin, they directly damage the DNA in skin cells, leading to inflammation and the characteristic redness and pain associated with sunburn. This radiation is also a pivotal factor in the formation of different types of skin cancers, particularly melanoma, basal cell carcinoma, and squamous cell carcinoma, as it promotes mutations in the skin cells.

Understanding the effects of UVB radiation is crucial for estheticians and anyone working in skin care, as this knowledge informs the practices and recommendations they provide to protect clients' skin health. While other options may describe effects associated with different types of radiation or skin concerns, UVB’s primary and well-documented role is its harmful impact through sunburn and its carcinogenic potential.
