I usually use needledepth 0,5 around eyes. On thin sensitive skin – I might go up to 1,0 mm in the rest of the face. On normal to strong skin I use between 0,5 to 1,5 mm. Will the results be better if I use deeper needle-lengths, if the patient can handle it..?
I usually treat at .25 around the eyes, .5 on cheekbone and forehead, and 1.0-1.5 on the rest of the face. I treat stronger, 2.0 on deep wrinkles or facial scars. And 2.5 on deep acne scars.
