According to different wire modification methods, it can be divided into 3 main organization effects:
(1) Remodeling effect. Through damage repair and biodegradation, it rebuilds the epidermis-dermis matrix structure, promotes local nutrient absorption and skin regeneration, and improves skin structure and elasticity. The tissue response includes promoting the division of keratinocytes in the basal layer, increasing the thickness of the basement membrane, forming elastic fibers, and promoting the production of type IV collagen around the blood vessels, making the epithelial crest at the dermal papillary layer and the dermis-epidermal junction more obvious.
(2) Lifting effect. After thread embedding, the tissues around the thread slowly form fibrosis. Macrophages, fibroblasts and mononuclear leukocytes infiltrate around the thread. The cell response is slight. The initial fibrotic connective tissue is composed of fine collagen fibers, and the later forms bundles of collagen. The fiber is accompanied by a small amount of active fibroblast infiltration, and this reaction continues until the PDO thread is completely absorbed, until the fibrotic collagen fiber bundle and the elastic collagen fiber bundle gradually replace the thread. This shows that the PDO embedding has a slow and long-lasting mechanism for improving the effect.
(3) Mechanical traction effect. As a means of anti-gravity tissue fixation, through the characteristics of the wire (serrated incision or anchoring structure), while stimulating the synthesis of new collagen, the comprehensive mechanical traction can achieve a lasting lifting effect.
It should be noted that adequate nutrient intake is a key factor for the synthesis of mature collagen fibers and elastic fibers.
The rapid pace of modern life, constant stress, unfavorable environmental factors, natural aging and nutrient loss require the body to supplement certain vitamins, minerals, antioxidants, amino acids and other biologically active substances, all of which help promote collagen production Synthesis and metabolism. The recipients after embedding need to supplement a lot of nutrients, and their intake is directly proportional to their age. The minimum intake time is 3 months, especially amino acid supplementation.
