More particularly, the present invention relates to a wound dressing which does not cause protein denaturation, a polyvinyl alcohol hydrogel which is stable for image healing, and an amniotic membrane extract hydrogel Layer hydrogels amniotic membrane extract-containing wet dressing and a method for producing the same. The wet dressing containing the bilayer hydrogel free amniotic membrane extract according to the present invention does not cause denaturation of the protein during the manufacturing process, thus securing the stability of the amniotic membrane extract as an active ingredient. Due to the ability to prevent infection, promote epithelialization, and alleviate keratinization, As the effect of treatment is improved, it has an excellent effect on skin regeneration treatment. |
