Microneedling for Medical and Aesthetic Purposes: Current Indications and New Advances

Abstract

Microneedling has become a valuable tool in dermatology, offering a non-surgical option to treat various skin conditions. The procedure creates microchannels in the skin, triggering the release of growth factors and promoting non-fibrotic skin remodeling. The current utilities for microneedling include treating wrinkles, scars, stretch marks, pigmentation disorders, warts, skin texture issues, rosacea, and hair regrowth. Multiple studies have shown its efficacy in improving these conditions, with significant improvements in patient assessments. However, further research is needed to optimize protocols and determine the ideal needle size, frequency, and interval between treatments for the best clinical outcomes for subjects. Through their novel research, clinicians have made significant advancements in microneedling, expanding its uses, and revolutionizing its application. Despite previous beliefs, microneedling can effectively treat active acne lesions without exacerbating the condition. It has also shown promise in treating facial spider veins, providing comparable efficacy to other methods with a better safety profile. Initiating microneedling treatment at an earlier stage for surgical scars improves outcomes compared to waiting for scar maturation. Microneedling combined with topical agents has shown positive results in treating gingival hyperpigmentation. Its expanding applications and recent advancements highlight the potential benefits of integrating microneedling into clinical practice.
