Sunburn is not actual burning of skin tissue; rather, it is the body's protective response where UV radiation damages DNA in skin cells, triggering a self-destruct sequence that sacrifices damaged cells before they can become cancerous, with the redness resulting from blood rushing to clear the damage and peeling representing dead cells shedding off.

Your Sunburn Isn't Burned Skin (Your Cells Are Killing Themselves)☀️本站添加:
That red skin isn't burned. Your cells are killing themselves. UV radiation damages the DNA inside your skin cells.
When the damage is too severe, the cells activate a self-destruct sequence. They sacrifice themselves before they can turn cancerous. The redness? Blood rushing to clear the damage. The peeling? Dead cells falling off. That's not a burn. Your skin saved your life.
