Background and aim: Skin rejuvenation is in demand. In recent years, mono- and bipolar radiofrequency (RF) have been reckoned as treatment of choice for this purpose. The studies on RF have shown the remodeling of collagen fibers and consequently improvement of skin texture although risks and side effects may exist.
Methods: Forty-eight patients requesting skin rejuvenation were treated by RF after obtaining written consent from them. The diagnosis had been made solely on the basis of examination and observation. The photography was performed in all patients pre- and post-treatment. The pictures were evaluated by a dermatologist unaware of the sequence of photos.
Results: the wrinkles improved in 26(54%) patients. The response was better with increasing age. Transient pain and erythema were reported by all patients.
Conclusion: Radiofrequency is an appropriate treatment for reducing the number and the depth of wrinkles and needs comprehensive education. At least, 4 treatment sessions with 2-week intervals are required for effectiveness.
