I would be pleased to answer your question .
are treated with Dermarollers which are fine needles that help in resurfacing the skin by modulating the collagen
. It is done at the Dermatologist
clinic and can cause redness
and swelling on the areas needled > IT works by modulating the collagen . It works well for scars and helps in reducing them further . The other options include lasers which you have already tried . If you have certain Ice Picked scars that is deep scars they are treated with a CROSS technique where the Tricholoacetic acid is applied inside the depth of the vertical scar . The other options are Subcision which involves breaking the acne scar
fibres and Laser treatments which work on the same principle above.
Thanks and take care
