La description

Micro-needling is the use of multiple needles that vertically pierce the skin to allow for greater absorption of topically applied skin care products, enhanced stimulation of collagen and elastin growth, and visible improvements in skin tone.

Micro-needling opens temporary channels in the most superficial layer of the skin and promotes the body’s natural healing process of producing new skin cells to replace aged or damaged skin.

Derma pen VS Derma rollers

Derma pen
 Minimised epidermal damage
 Less pain and erythema as high speed with vertical direction
 More easy to operate at the small or curved areas
 Adjust micro needle length (0.*5~2.0mm)
 Prevent cross infection, adopt with disposable needles
 More quickly and efficient than manual Micro-needle

Derma rollers:
 More painful with a lot more bleeding due to epidermal damage
 Difficult to use in small or curved areas
 Difficult to insert needle into scar tissue—needles can be bent
 No needle height adjustment
