Old scars, from between the ages of twelve and 26. (35 now). Is there any treatment which might reduce their appearance? My friend does Glycolic peels (at a very low acidity). I'm a bit worried about going for anything too invasive in case the scars are worsened. When I had four microdermabrasion treatments eight years ago, the practitioner said that Ice Pick scars can look worse the further down a treatment goes. Does anyone know if this is true? P.S. I'm UK based, Wales specifically, so if anyone knows of reputable treatments (and prices) here, I'm all ears!
