Nonsurgical Augmentation of the Chin Using a Lateral to Medial Approach with Hyaluronic Acid Based Filler: A Case Series.

The chin is recognized as an essential element in overall facial balance and contributes to the perception of youthfulness. Age-related chin retrusion and resorption can alter the shape and projection of the chin, disrupting facial harmony. Hyaluronic acid-based dermal fillers offer a temporary, non-surgical option to correct mild to moderate chin retrusion and resorption. In this case series of three patients, we sought to describe a modified injection technique of the chin with hyaluronic acid-based filler using a tapered lateral to medial approach aimed at correcting mild to moderate chin retrusion and resorption. The aesthetic improvement in appearance, compared to pretreatment, was measured by the investigators using the Global Aesthetic Improvement Scale. Each patient received either a score of 4 or 5 indicating improvement from baseline or achievement of optimal corrective results, respectively. An advantage of using this approach is that starting from a lateral to medial approach with a needle allows the injector to rebuild the chin compartment using precise volumes of filler, requiring minimal total filler volume to achieve optimal corrective results. While this report demonstrates promising results in aesthetic outcomes, further research is required to demonstrate reproducible results and long-term efficacy.

Lip Augmentation With Hyaluronic Acid Fillers: A Review of Considerations and Techniques.

Lip augmentation has become a key component in addressing cosmetic concerns in dermatology practice today. In particular, hyaluronic acid (HA) fillers are increasingly used for this minimally invasive procedure. In order to achieve the optimal cosmetic and aesthetic outcome, a fundamental understanding of the relevant anatomic components is necessary: this article details lip topography, muscular and subcutaneous organization, and pertinent vascular structures of the lip, while also highlighting important changes that occur with aging. In addition to understanding the disposition of HA fillers, we also discuss specific injection techniques commonly used in practice. Finally, injection of HA fillers is not without complications; physicians must be knowledgeable of both the possibility of complications and management thereafter. This article details anatomical review, specific procedural technique, and safety considerations to be mindful of when using HA fillers for lip augmentation.

Platelet-Rich Plasma: A Comprehensive Review of Emerging Applications in Medical and Aesthetic Dermatology.

Platelet-rich plasma (PRP) has been integrated into numerous treatment regimens for medical and aesthetic dermatology. While some of these approaches are well-established, many uses are underreported in the literature. We sought to identify and summarize the emerging dermatologic applications for PRP by conducting a comprehensive PubMed search of studies published between 2000 and 2020. These studies were reviewed to synthesize collection methods, treatment schedule, adverse effects, and the impact of therapy for new and emerging uses for PRP. In general, we identified positive treatment outcomes for skin rejuvenation, scar revision, alopecia, pigmentary disorders, lichen sclerosus, leprosy-induced peripheral neuropathy, plaque psoriasis, and nail disorders. Widely, therapy was well-tolerated and suitable for all reported phototypes. The variations in collection and application sequences make concrete recommendations difficult to discern, underscoring the need for a standardized approach to preparation and treatment methods. We hope this review serves as an outline for new and interesting uses for PRP and will help readers familiarize themselves with this exciting technology for comfortable integration into their practices.
