AbstractAn atrophic scar is a prevalent cosmetic condition. It happens as a result of diminished production of connective tissue, and inadequate compensation of dermal collagen that happens throughout the process of tissue regeneration following injuries. Various techniques may be employed for dealing with atrophic scars, including subcision, peeling with chemicals, dermabrasion, punch grafting, and the application of filler materials to improve depressed areas. Subcision, or subcutaneous incisionless operations, is a kind of surgery that targets various skin issues such as atrophic scarring from acne, wrinkles, depressed scarring, and cellulite. The subcision technique for scar healing involves the release of fibrotic strands that are located underneath the scars, the organization of blood inside the resulting dermal pocket, and the development of connective tissue in the scarred region. Threads insertion has become a common trend in soft tissue and facial skin suspension. The threads function by being inserted into the human body's tissues, which prompts the development of a fibrous capsule around them. This capsule may serve as a supportive structure inside the soft tissue matrix. Additionally, the presence of inflammation leads to an increase in collagen.
