Microneedling: The Key to Beautiful Skin

Microneedling is a revolutionary skincare technique that uses tiny needles to create microchannels in the skin. These microchannels stimulate the production of collagen and elastin, essential components for firm and smooth skin. The Dr. Pen M7 Dermaheal cartridges are designed to provide optimal results, addressing various skin concerns such as:

  • Scarring
  • Hyperpigmentation
  • Loose skin and sun damage
  • Stretch marks
  • Uneven skin tone and texture improvement

  • Hair loss

  • Scarring: 1.0mm – 1.5mm
  • Hyperpigmentation: 0.25mm – 1mm
  • Loose skin and sun damage: 0.5mm to 1.5mm
  • Stretch marks: 1.5mm to 2.5mm
  • Uneven skin tone and texture improvement: 0.5mm – 1mm
