Abstract

The invention discloses a scar sun-screening and repairing silicon gel and a preparation method thereof. The scar sun-screening and repairing silicon gel is prepared from the following raw materials in percentage by weight: 55-90% of polydimethylsiloxane, 1-20% of a sun-screening agent, 0.2-8% of an antioxidant substance and 2-35% of a solvent. Experiments prove that the scar sun-screening and repairing silicon gel disclosed by the invention is good in sun-screening effect and is capable of inhibiting scar hyperplasia; upon clinical tests, the effective rate of repairing scars after sun exposure is more than 90.00%; the silicon gel is conducive to the protection and repairing of scars under a condition of sun exposure, and the silicon gel is capable of diluting chromatosis and taking a significant effect; and the preparation method disclosed by the invention is simple, short in production cycle, simple in prescription and low in cost.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a scar sunscreen repair silicone gel which can achieve better healing effect by sunscreen, moisturizing and anti-oxidation for damaged skin. Background technique [0002] As early as 1983, Perkin et al. added a silicone gel film between the elastic band and the scar to prevent direct friction when using the elastic band to compress the scar, and found that the effect was much better than that of the elastic band alone. Thus uncovered the inhibitory effect of silicone gel on scars and has received extensive attention. [0003] Studies have pointed out that silicone gel has the effect of treating scars because silicone gel can form a layer of silicone gel film after being applied to damaged skin, which can slowly and continuously release silicone oil, and silicone oil helps to separate necrotic tissue , Accelerate the proliferation of granulation tissue and the for...
