Red patches on the body.

Red spots on the body may be caused by subcutaneous congestion. The cause of subcutaneous erythema may be trauma, decreased coagulation function, or allergic factors. In addition, red spots may be caused by pigments. If erythema is allergic, anti-allergic drugs such as loratadine can be used for treatment. If erythema is caused by decreased coagulation function, vitamins can be supplemented. If pigment stains are pigmented, they can be treated by physical methods such as laser.
