What is the difference between Dermaroller and other skin rejuvenation techniques?

In contrast to all ablative techniques like Lasers and Fractional Laser treatments, the Dermaroller stimulates new tissue formation – it acts constructively and the skin remains intact. The skin does not get damaged (unlike other needling devices) and therefore will not go into a wound healing response. The Dermaroller significantly improves atrophic scars & improves skin texture.
