Sunburn

Sunburn is medically called solar dermatitis, also known as solar erythema, which is an oval protrusion or smooth, dark brown plaque that easily appears on the outside of the forearm, the back of the hand, the front of the calf, and the face. To the size of a penta coin, it usually appears in middle age. After exposure to the sun, erythema, edema and other symptoms occur on the exposed skin. After that, pityriasis-like desquamation occurs and skin pigmentation occurs. Sunburn is formed by sunlight or other light. It is an acute damaging reaction caused by the skin to strong light and is a photosensitive skin disease.
