Needle rollers also use needles for skin resurfacing but are often too large and unwieldy for tight areas. They are also dependent on hand pressure, so the depth of penetration varies depending on the the amount of pressure exerted and the softness of the skin, while the Dermapen depth of penetration is set precisely with an electronic dial. There is also lateral trauma to the skin when the needles on a roller pull out of the skin as the wheel turns. This does not happen with the Dermapen, which relies only on vertical needle action
Dermapen uses multiple needles that vertically pierce the skin. This enhances rejuvenation results and is far safer for the client because there is much less epidermal damage.
The automatic vibrating function of the Dermapen increases the effectiveness of treatment by increasing absorption of products, while reducing pain and discomfort.
Dermapen is just as effective as ablative treatments such as Fraxel, IPL, Laser Resurfacing, and Chemical Peels. The most amazing benefit is that Dermapen's pricing is a fraction of the leading alternatives.
