A completely different picture emerges when hundreds of fine needle pricks are placed close to each other. When a needle penetrates into the skin, the injury causes localized damage and minor bleeding by rupturing fine blood vessels. The roller is a drum-shaped device with very fine protruding stainless steel needles (0.25-3mm in length) that was designed by Fernandes 12 to closely puncture the skin.

9, 10 The technique involves puncturing the skin multiple times using needles, a tattoo gun, or roller. 2, 8 It is currently used in the cosmetic art to treat several skin conditions, such as pigmentary disorders, wrinkles, post-acne atrophic scars, burn-related scars, and big pores and is also a part of percutaneous collagen induction (PCI) therapy. It is thought that needles break collagen bundles in the superficial layer of the dermis that are responsible for scars with subsequent induction of more collagen immediately under the epidermis. Multiple methods including topical preparations, dermabrasion, laser resurfacing, punch excision, punch elevation, subcutaneous incision, chemical peels, dermal grafting, and fillers, as well as fat transfer, implantation of autologous collagen and cultured and expanded autologous fibroblasts, focal treatment with trichloroacetic acid, and skin microneedling (automated or dermaroller) have been used to treat post-acne scars via enhancement of dermal extracellular matrix (ECM) proteins. It is common for patients to have more than one type of scar. However, the most basic and practical system classifies post-acne atrophic scars into the following three main types: 1) icepick, 2) rolling, and 3) boxcar scars. 1, 2ĭifferent classification systems of varying complexities have been introduced to classify post-acne atrophic scars into many morphological types. Different terms and surgical techniques have been used to describe the types of acne and to improve the appearance of scarring. In some patients, the severe inflammatory response results in textural change in the superficial and deep dermis, leading to post-acne scars. Conclusions: Multiple minimally invasive sessions of skin microneedling are an effective treatment for post-acne atrophic scars as it stimulates the repair processes with the advantage of being a relatively risk-free, in-office procedure with minimal patient recovery time.Īcne is a common condition seen in up to 80 percent of young people and in five percent of older adults. There was a statistically significant increase ( p<0.05) in the mean of collagen types I, III, and VII and newly synthesized collagen, while total elastin was significantly decreased ( p<0.05) after the end of treatment.
Results: Compared to the baseline, patients’ evaluations revealed noticeable clinical improvement in atrophic post-acne scars in response to skin microneedling. Histometry for epidermal thickness and quantitative evaluation of total elastin newly synthesized tropoelastin collagen types I, III, and VII and newly synthesized collagen were performed for all biopsies. Measurements: Patients were photographed, and skin biopsies were obtained at baseline as well as one and three months from the start of treatment.
Participants: Ten patients with different types of atrophic acne scars were subjected to three months of skin microneedling treatment (six sessions at two-week intervals). The aim of this study is to evaluate the clinical effect and objectively quantify the histological changes of acne scarring in response to skin microneedling. Microneedling therapy or percutaneous collagen induction is a new addition to the treatment modalities for such scars and has been reported to be simple and effective in atrophic acne scar treatment. Objective: Treatment of acne scarring is always a challenge.
