Was exposed to very severe sunburn on shoulders and back. For the first week the skin became yellow, and would sweat from beneath if exposed to water, like an exoskeleton, and all moles became very dark. After the first week, the skin finally started to peel off completely of the torso. Finally, about 2 months after, all moles are still much darker then from before the incident and skin on the shoulder feels rough to the touch as if it is calloused. I m a male in 30 s.
