It is minimally invasive, involves minimal or no downtime, rapid healing and requires simple aftercare.Immediately after your Dermaroller Therapy you will look as though you have moderate sunburn and your skin may feel warm and tighter than usual. This will start to subside after 1 to 2 hours and will normally recover within the same day. You may have slight redness the following day or two.What can the Derma Roller System treat?The Derma Roller System can be used by both women and men and has numerous beneficial effects including:- Anti Ageing- Anti Wrinkle- Cellulite Treatment / Cellulite Reduction or Removal- Hair Loss Treatment / Hair Restoration- Hyper Pigmentation Treatment- Scar Removal - including acne scar removal- Skin Smoothing- Stretch Mark Removal How fast does the Derma Roller get results?The speed at which you will get results depends on what you are treating and how extensively your body needs to remodel theaffected area.
