Microneedling is an effective treatment for scars and stretch marks by stimulating collagen and elastin production. The tiny, controlled punctures created by the fine needles break down scar tissue and promote the regeneration of healthy skin. For stretch marks, microneedling helps to smooth and improve texture by boosting collagen production in the affected areas. This process results in smoother, firmer skin with improved appearance over time, with multiple sessions for optimal results.
