Local skin tightening

Local skin tightening is most common in scleroderma. Scleroderma is also called systemic sclerosis. As the name suggests, it is a disease where the skin hardens. Skin changes are a hallmark of systemic sclerosis. However, the extent of the lesions is very different. The mild ones have only localized skin sclerosis and calcification, and the severe cases may have widespread skin sclerosis and thickening. Typical skin lesions go through three stages of swelling, infiltration and atrophy in turn. The lesions are symmetrical. Most of the lesions gradually expand from the fingers to the proximal end, and the boundary between the lesion skin and normal skin is unclear.
