Abstract
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.

Abstract
Aging and wrinkles on the face and neck are natural processes throughout a person's life. On these days, there are various techniques to treat these facial lines. The non-invasive facelift technique is suggested considering the risks and effects of different cosmetic procedures. This research collected information about using polymer threads for lifting the face and treating ptosis from authentic scientific texts published in databases such as PubMed, Google Scholar, Science Direct, and Web of Science. The investigations showed that when placed correctly, biodegradable polymer threads cause skin irritation and promote collagen formation, so that’s interesting for patients and doctors. Patients undergoing a facelift with polymer threads experience fewer complications than those undergoing traditional methods. Despite the low side effects of this method, some patients have opted to remove the threads after the lift due to dissatisfaction with their appearance. Threads with superficial spines and biodegradability are considered popular and attractive for lifting the soft tissue of the face due to their quick recovery and low cost. Different types of absorbable threads are available in the market, each with different compositions and have different designs depending on the place of use. This review study will discuss biodegradable polydioxanone (PDO), polycaprolactone (PCL), and polylactic acid (PLLA) yarns.
