Micro-needling is a cosmetic procedure, in which tiny sterile needles are used to create controlled micro-injuries on the skin. This is done with the help of a special device called a dermaroller or a motorized wand. The procedure works by encouraging the skin to produce more collagen, which can help reduce the appearance of fine lines, wrinkles, acne scars, and other skin imperfections. Micro-needling has many benefits, including improving skin texture, tone, and firmness. The technique can be used on any part of the body that needs to be rejuvenated, including the face, neck, chest, and hands. The procedure can be done in a medical setting, at a spa, or at home with the right equipment, and it usually takes several sessions to see results.
