Abstract

The invention relates to the field of medicine, in particular to a medical dressing for pigmented dermatosis and a preparation method of the medical dressing. The medical dressing includes gamma-polyglutamic acid, hyaluronic acid, arbutin, glutathione and L-VC phosphate. The properties and efficacy of polyglutamic acid are utilized, and hyaluronic acid, arbutin, glutathione and L-VC phosphate areloaded at the same time, so that wound repair is promoted, production of melanin is reduced through inhibition of the activity of tyrosinase, control on synthesis and secretion of melanin, resistanceto stimulation of external undesirable factors and other means, and better therapeutic effects are achieved.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a medical dressing for pigmented skin diseases and a preparation method thereof. Background technique [0002] Pigmented dermatosis is caused by abnormal melanocytes and melanin production, which can be caused by genetic and environmental factors. It is a common disease in skin diseases. Although most pigmented dermatoses do not pose a major hazard to health, they hinder beauty, thereby causing mental stress to patients and affecting their work, study, and daily life. With the improvement of people's material living standards, clinically, more and more cases come to see a doctor because of pigmented diseases. [0003] Melanotic skin diseases refer to pigmented skin diseases caused by increased melanin production, including: freckles, pigmented nevus, coffee spot, chloasma, freckle-like nevus, melanosis, nevus of Ota, pigmented hairy epidermal nevus, generalized Sunspot disease, pityrias...
