The needle shaping technique can be used to perform subcutaneous microtransplants, enabling the 'lifting' of the skin. This prospective cohort study aimed to examine the effects of needle shaping on facial skin tone, volume and histological structure. A total of 54 women underwent the needle shaping procedure performed by inserting a tiny acupuncture needle combined with mixed electrical currents. The overall treatment was completed within 4 sessions of 2 months apart, once every 15 days. Maintenance was ensured by 2 sessions (no longer than 15 days apart) every 6 months. Macroscopic skin appearance was evaluated by a specialized dermatologist and the satisfaction of the patients was assessed. The microscopic structure of the skin dermis was evaluated by optic and scanning electron microscopy. I-chrome staining demonstrated more compact dermis-collagen fibers which were larger and thicker as compared to the controls. Scanning electron microscopy demonstrated an increased dermis thickness as compared to pre-treatment. All patients that answered to the follow up reported satisfaction during assessment. The satisfaction of the patients was very good and excellent in 45% of cases. The results of the needle-shaping procedure are natural with no scaring or down time. Moreover, the result is lasting even for 1 year, depending always on the subject's lifestyle and general health condition.
