Microneedling: A Means of Collagen Induction Therapy

Microneedling, or collagen induction therapy, involved using a dermaroller to create micro-injuries in the skin, stimulating collagen production and aiding in wound healing. It was effective for treating various skin conditions, including acne scars, wrinkles, stretch marks, and alopecia, with 88.7% of patients showing good-to-excellent responses for certain scar types. The procedure promoted neocollagenesis and neovascularization, enhanced transdermal drug delivery, and could be combined with other treatments for better outcomes. It required multiple sessions, had minimal side effects, and was cost-effective. Techniques like fractional microneedling radiofrequency (MFR) and LED microneedling further improved collagen remodeling and skin rejuvenation with minimal side effects.
