Buttock improvement and augmentation have become a whole new challenge to the medical aesthetics field. Nowadays, besides surgical options, the only available non-surgical treatment for gluteal augmentation is the injection of biocompatible fillers. Nevertheless, these minimally invasive treatments have their own limitations. In the quest to find a better option to treat this specific area, the idea of using polycaprolactone (PCL) to enhance the gluteal area emerged. The case of a 26 year-old female patient who desired a non-surgical buttock enhancement is presented. She was treated with PCL-based filler to achieve such an improvement. The clinical photographic results were outstanding, with a nine out of 10 overall satisfaction subjective score. In conclusion, using PCL could become a new alternative to non-surgical gluteal enhancement. Due to the collagen biostimulation property of the filler, the treatment will also enhance the skin quality, giving the buttocks an overall improvement.

Hyaluronidase is perhaps the most important enzyme in the medical aesthetics field. The relevance behind this enzyme lays within its ability to be the direct antidote of exogenous hyaluronic acid. 1

With the breadth and variety of hyaluronic acid hydrogels available, it can be challenging to understand the evolving product characteristics and associated terminology. Similarly, different hyaluronic acid hydrogels can share the same indication, and yet consist of different rheological and physiochemical properties. In this paper, hyaluronic acid biophysical properties, such as molecular weights, stabilisation (crosslinking), modification and hyaluronic acid concentration, are explored in relation to findings from current literature. The significance for these specific properties is explored in relation to specific indications and anti-ageing benefits.
