Tissue Fillers for the Nasolabial Fold Area: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Ellansé: Advanced Technology and Advantageous Selection of New Collagen Stimulating Agents for Face Rejuvenation

Facial injections have a comparative mature market and system in China, but all kinds of injection materials have their own advantages and disadvantages, even hyaluronic acid, as the most common injection material, can form an unnatural stiffness after injection. Currently, Ellansé, a biodegradable collagen stimulator, has shown superior aesthetic results while ensuring safety and naturalness, making it a more preferable choice for a variety of facial injections. The purpose of this review is to introduce the features and benefits of Ellansé, so that doctors in the field can better understand and learn how to use it properly and minimize the risk of complications, and have a better choice for the medical aesthetic field in China in numerous aspects. The papers with the keyword "Ellansé" is very few in number, and there is a lack of systematic overview. Ellansé itself has unique advantages for the Chinese population, as it is an attractive option for the treatment of aging face due to high patient satisfaction, long-lasting results and low side effects (Guo et al. in J Cosmet Dermatol 21(5):1959-1966, 2022). More clinical data will be available in the future to confirm its performance and longevity in various sites.

The application of a multi-component reaction peptide as a model regenerative active to enhance skin wound-healing postlaser procedure in a double-blinded placebo-controlled clinical trial

INTRODUCTION

Esthetic procedures are currently among the most effective options for consumers seeking to correct aging signs such as fine lines, wrinkles, and skin tone unevenness. Currently, there is a scientific need for an adjunct active to be paired with esthetic procedures to encourage wound recovery and address postprocedure pigmentation concerns.

OBJECTIVE

Toward that goal, this study assessed the efficacy of a peptide created from a multi-component reaction (multi-component peptide, MCP) as a model active for postprocedure care and evaluated its ability to promote skin healing in an ablative laser-induced wound model on the forearm.

METHODS

The mechanism of action of MCP was investigated using tubo assays, 2D melanocyte, and fibroblast cultures, reconstructed skin equivalents, and ex vivo skin explants. The MCP formula and the clinical benchmark formula of Aquaphor were assessed head-to-head by applying the products topically in an ablative laser-induced wound model (n = 20 subjects). The promotion of wound healing was evaluated by the investigator assessment of epithelial confluence, crusting or scabbing, general wound appearance, erythema, and edema.

RESULTS

MCP was determined to be beneficial to postprocedure skin recovery and healing by four main mechanisms of action: barrier repair as determined in an ex vivo tape-stripping model, reduction of inflammation and postinflammatory hyperpigmentation, reduction of elastase activity, and stimulation of fibroblast through the mTOR pathway. The formula containing 10% MCP enhanced the kinetics of epithelial confluence and improvement of the crusting or scabbing appearance of the laser-generated wounds in a laser-induced mini-zone wound healing study on the forearm.

CONCLUSION

This study demonstrates the use of MCP as a proof of concept regenerative active that when incorporated into an optimized postprocedure skincare formula can improve skin healing and enhance the appearance of skin after injury with relevance to ablative aesthetic procedures.

Expert recommendations on the assessment and management of complications due to hyaluronic acid soft tissue filler injections in Asians

BACKGROUND

The use of hyaluronic acid (HA) fillers for medical aesthetic purposes is increasing worldwide. Nonetheless, adverse events do occur because of patient-specific issues, injection technique, or product factors. It would be mandatory to consider cultural and anatomical features of Asians in preventing and managing the complications of HA injections.

METHODS

Literature search of studies looking at current evidence and guidelines on the management of complications following HA filler injections in Asian patients was conducted. This was followed by an expert group discussion that was convened to reach consensus recommendations on the best clinical practices.

RESULTS

The expert panel provided specific recommendations focusing on the safe use of soft tissue fillers in Asian patients, including early identification of adverse events and how to prevent and comprehensively manage these outcomes.

CONCLUSIONS

Here, we provide consensus statements of Asian experts in dermatology, plastic surgery, ophthalmology, and aesthetic medicine mainly focusing on AEs with higher risk for Asians and can be used to guide physicians in treating Asian population.
