Novel Chitosan Dermal Filler with Enhanced Moldability and Elasticity.

Macromol Biosci 2022 Jun 13:e2200081. Epub 2022 Jun 13.

Department of Plastic and Reconstructive Surgery, Seoul National University Boramae Hospital, Seoul National University College of Medicine, 5 Gil 20, Boramae-Road, Dongjak-Gu, Seoul, 07061, Republic of Korea.

Currently, dermal fillers are largely based on commercialized cross-linked hyaluronic acid (HA) injections, which require a large injection force. Additionally, HA can be easily decomposed by enzymes, and HA-treated tissues present a risk of developing granuloma. In this study, a chitosan-based dermal filler is presented that operates on a liquid-to-gel transition and allows the injection force to be kept ≈4. Read More

COVID-19 and Dermal Fillers: Should We Really Be Concerned?

Actas Dermosifiliogr 2022 Jun 2. Epub 2022 Jun 2.

Servicio de Dermatología, Hospital Universitario 12 de Octubre, Madrid, España; AG BIOMEDIC CLINIC, Madrid, España. Electronic address:

SARS-CoV-2 has caused millions of infections and deaths worldwide and case numbers continue to rise. Besides the effect of the virus on key organs - leading to respiratory illness, anosmia, diarrhea, and fever and other complications - delayed inflammatory reactions to hyaluronic acid dermal fillers, mainly in the face, have also been reported to occur after confirmed SARS-CoV-2 infections and in vaccinated individuals. While delayed inflammatory reactions tend to be self-limiting, they should be diagnosed and treated with corticosteroids, hyaluronidase, and/or antibiotics when necessary. Read More

Application of Cross-Linked and Non-Cross-Linked Hyaluronic Acid Nano-Needles in Cosmetic Surgery.

Int J Anal Chem 2022 23;2022:4565260. Epub 2022 May 23.

Gansu Provincial Maternity and Child-care Hospital, Lanzhou, Gansu 730050, China.

The common feature of non-cross-linked hyaluronic acid nano-needles is that they penetrate the skin and dissolve rapidly, and the non-cross-linked hyaluronic acid will migrate under the skin, so it is difficult to maintain the long-term expansion effect in a fixed position. In order to achieve the relatively long-term antiwrinkle effect, a kind of cross-linked and non-cross-linked compound hyaluronic acid microne was prepared. By inserting the microne under the skin, dissolving the non-cross-linked part under the skin and introducing the cross-linked gel particles under the skin, the effect of extending the microne was achieved.

Department of Oral & Maxillofacial Surgery, Faculdade São Leopoldo Mandic, Campinas, Brazil.

Orthognathic surgery has an undeniable functional effect, but the aesthetic result must not be disregarded, especially since many patients visit the surgeon precisely because of an aesthetic complaint and ignore the practical benefits. The aim of this paper is to discuss about an ideal treatment that combines this functional improvement with facial aesthetics and improves it after the operation. In order to predict which aesthetic deficits may occur, a facial analysis is essential. Read More
