Abstract
Hyaluronic acid (HA), the main and most important constituent of extracellular matrix, is a glycosaminologycan with water-absorbing capacity found in large amount in growing and repairing tissues. One of the main causes of skin problems, particulary in aging skin, is HA deficiency. More than half of the body HA is in the skin and is necessary for the maintenance of internal matrix and several cellular functions. Filler gels containing HA are used to repair skin defects. As these substances are derived from animals and bacteria, not the human, may cause skin reactions and have short half-life. So efforts to maintain and/or increase HA secretion from skin fibroblasts are important in the prevention and treatment of skin aging.

Abstract
Background and Aim: Recently, many Iranian companies have started manufacturing hyaluronic acid based dermal fillers. Current review aimed to assess and compare the clinical safety and efficacy of 5 Iranian hyaluronic acid based dermal fillers.
Methods: The first part of the study reported, the overall safety and efficacy of 5 Iranian hyaluronic acid based dermal fillers for improvement of nasolabial folds in 150 participants (age 44.30±9.97 years) using clinical and objectives assessment methods. In the second part, we performed a comparative study among 5 tested dermal fillers.
Results: Generally, at weeks 2, 12, and 24, 80.6%, 63.3%, and 60.66% of the participants, showed one grade or more improvement in the severity of nasolabial folds respectively. In all visits, the nasolabial folds biophysical parameters as well as the echo density dermis improved significantly compared to baseline. In comparative study, two fillers with the hyaluronic acid concentration of 24 mg/ml, showed the best objective efficacy, while in clinical evaluations, the filler containing mannitol has the best performance in reducing the severity of nasolabial folds showed.
Conclusion: Iranian hyaluronic acid based dermal fillers showed different levels of safety and efficacy for improvement of moderate to severe nasolabial folds, with efficacy.

Abstract
Cosmetic dermatology has seen significant advancements in developing new materials and techniques to enhance skin beauty and combat signs of aging. One notable development is creating and analyzing fillers made by combining hyaluronic acid and polycaprolactone. This innovative filler type has gained popularity due to its unique properties, exceptional skin rejuvenation capabilities, and effectiveness in facial contouring. This study gathered information on dermal fillers and the effects of using hyaluronic acid and polycaprolactone by referencing papers from various databases such as Civilica, PubMed, Google Scholar, Science Direct, and SID. The authors conducted a study to explore the benefits and drawbacks of utilizing hyaluronic acid and polycaprolactone and their impact on filler durability and injectability. Research conducted by experts and studies on cosmetic fillers has highlighted the positive effects of hyaluronic acid and polycaprolactone, two powerful substances widely discussed in the beauty industry. Further research could improve the understanding and utilization of hyaluronic acid/polycaprolactone fillers, enhancing skin cosmetic treatments and increasing patient satisfaction.
