Dermatologist Debunks the Myth of the 'Healthy Tan'

Sunburn Science: Why There's No Such Thing as a Healthy Tan The UK is currently experiencing a heatwave, and many people are seeking the sun's rays. However, a recent video by dermatologist Dr Emma explains the dangers of sun exposure and the myth of a healthy tan. Dr Emma uses simple diagrams to illustrate how UV radiation damages skin cells. She explains that when the sun shines on the skin, UV radiation hits the skin cells, potentially causing mutations in the DNA. This can lead to skin cancer and other problems. The melanocyte, a cell near the skin cell, detects this danger and releases melanin to protect the skin cell's nucleus. However, if the damage is excessive, the skin cell dies, resulting in a sunburn and the peeling of the skin. "So melanin is your skin's protector," explains Dr Emma, "and when you get a tan, it's your skin telling you that you're subjecting it to potential damage. That's why there's no such thing as a healthy tan." Dr Emma's video serves as a timely reminder of the importance of sun safety during hot weather. Protecting your skin from harmful UV radiation is crucial for preventing long-term health issues. The video's clarity and simple explanations make it an excellent resource for educating the public on the science behind sun damage.
