Background

Acne is usually caused by propionibacterium infection, excessive sebum secretion, strong androgen secretion, abnormal formation of lipid plugs in follicular keratosis, inflammation and the like. It is good for teenagers, also called as acne and comedo.

The scar is easily formed when the organism suffers from severe acne, and the scar is generated by self-repairing of the skin after the skin is injured and is formed by hyperplasia and accumulation of a large amount of collagen fibers. The tissue pathological characteristics and clinical characteristics are differentiated to be classified into superficial scars, atrophic scars, hypertrophic scars and keloids. The generation of scar has certain genetic susceptibility, can regulate the expression of key genes and inhibit the generation of scar. Antisense oligonucleotide technology is to use artificial preparation or organism to synthesize antisense DNA or antisense RNA segment of target sequence, which can be specifically complementary with target mRNA or DNA, to inhibit the transcription of the gene, prevent its expression and make its function lost. Selectively degrade the gene family containing the subsequence high homology and inhibit the expression thereof, thereby having the characteristics of high transfection efficiency, strong specificity, high activity and the like.
