Why does your skin remain red after a bad sunburn? a) Blisters form, lifting the epidermal layer. b) Inflammation causes increas
Mandarinka [93]

Skin remains red after a bad sun burn because:

inflammation causes increased blood flow.

Explanation:

When our skin is exposed to sun rays , the epidermal layer starts getting damaged. The damage to the cell caused by  sun rays triggers the  melanin secretion. Increased secretion of melanin results in darkening of the exposed region .

However, the damage and inflammation to the skin increases blood flow to the skin, this causes reddening of the skin.
