Non-invasive peri-orbital rejuvenation: radiofrequency dual radiowave energy source (RF) and light emission diode system (LED).
BACKGROUND
Non-ablative skin rejuvenation is becoming increasingly popular. Ellman RF produces an electric current that generates heat in the dermis producing a contraction of the collagen. LED is a non heating light emission system that induces fibroblast proliferation.


METHODS
30 Caucasian women, prototype I-IV, age from 35 to 65 with peri-orbital photo damage were randomly divided in 3 groups. Group 1 received: 5 RF sessions, 1 every 10 days. Group 2 received 8 LED sessions, 1 every 5 days. Group 3 received RF and LED: 1 RF, 2 LED sessions every 5 days for 3 times (3 RF and 6 LED sessions). A score of satisfaction, considering skin texture, rhytidis reduction and firmness was obtained before the treatment, after each session and 2 months after the last session.


RESULTS
Two months after the last treatment in group 1:7 patients were satisfied and 3 were very satisfied; in group 2: 6 patients were satisfied and 4 were very satisfied, in group 3: 4 patients were satisfied and 6 were very satisfied. LED was effective on improvement of skin texture and rhytidis reduction while slightly effective on firmness. RF was effective on skin texture and firmness while slightly effective on rhytidis reduction. LED and RF together were effective on all parameters.


CONCLUSIONS
LED and RF seem to be safe and effective on skin rejuvenation especially when associated.
