Erythroderma mainly refers to the appearance of the skin caused by the thickening of the diameter or increase in the number of capillaries in the local skin, which may be related to exposure to certain specific substances or temperature changes. To remove erythema, you can choose to use topical ointments with physical therapy for improvement. Topical medications can be applied with hyaluronic acid gel or vitamin E cream, which can effectively thicken the skin’s stratum corneum and increase the thickness of the skin, and have an improving effect on the erythema caused after skin exfoliation. You can choose to use mucopolysaccharide polysulfate cream, which is effective in aiding the reduction of temporary redness caused by eczema and dermatitis. Pulsed fuel lasers can also be used to thin the diameter and reduce the number of red blood cells to achieve a therapeutic effect.
