What is a primary concern with indoor tanning, according to dermatologists?

The primary concern with indoor tanning, as emphasized by dermatologists, is that it raises the risk of developing melanoma, a serious type of skin cancer. Indoor tanning exposes the skin to ultraviolet (UV) radiation, which can cause direct damage to the DNA in skin cells. Over time, this damage accumulates and leads to mutations that can result in cancerous growths. The World Health Organization has classified indoor tanning devices as carcinogenic to humans, further supporting the link between indoor tanning and an increased incidence of melanoma.

While other factors like vitamin D deficiency, accelerated skin aging, and issues with skin oiliness can be associated with tanning practices, the predominant health risk that dermatologists highlight is the increased likelihood of melanoma development as a direct consequence of UV exposure from indoor tanning.
