Application of Nonsurgical Modalities in Improving Facial Aging

Abstract

Objective. This review aims to summarize different kinds of applications of minimally invasive surgery in improving facial aging to provide a comprehensive and accurate introduction on the issue of esthetic treatment of facial skin. Overview. In the twentieth century, facial rejuvenation has become a new beauty trend. Facial cosmetology has entered a period of antiaging and rejuvenation therapies and microplastic surgery. The pursuit of beauty has promoted the development of minimally invasive plastic surgery. This review introduces the possible causes of facial aging and its related topics with a focus on facial injectable drugs, such as botulinum toxin, main filler materials (hyaluronic acid, calcium hydroxyapatite, poly L-lactic acid, collagen, autologous fat, and polymethyl methacrylate), and some current antiwrinkle technologies, such as thread lift and radiofrequency rhytidectomy. Conclusions. Despite the difference in mechanisms of action, each technique can address facial aging involving the loss of collagen, displacement and enlargement of fat, and muscle relaxation. Combinations of these treatments can provide patients with reasonable, comprehensive, and personalized treatment plans.

Poly‐L‐Lactic acid increases collagen gene expression and synthesis in cultured dermal fibroblast (Hs68) through the TGF‐β/Smad pathway

“…5 As demand increases, safe and effective facial fillers are being updated, such as biodegradable calcium hydroxyapatite, polycaprolactone, hyaluronic acid, and non-biodegradable poly-meth methacrylate silicone, polyacrylamide, and autologous fat grafting. 6,7 Poly-L-Lactic Acid (PLLA) is a biocompatible, biodegradable, absorbable, immunologically inert, malleable, and easy-to-process polymeric synthetic polymer derived from plants that have been used in previous studies of synthetic suture materials. It was approved by the food and Drug Administration (FDA) in 2004 for the treatment of facial fat atrophy following immunodeficiency virus infection and in 2009 for nasolabial folds and other dermal wrinkles.…”

Assimetria labial: uma correção local apenas?

“…Quando aplicados nas camadas dérmicas, os preenchedores faciais encontram forças envolvidas na sustentação do tecido que podem interferir na qualidade do material e, por isso, avaliar a reologiaou a forma como o material reage e se deforma em consequência do estresse mecânicodos tipos de AH existentes no mercado em resposta a estes estímulos musculares e gravitacionais nos permite escolher adequadamente o produto (Pierre, et al, 2015;LI et al, 2022).…”

Morpho-Functional Effect of a New Collagen-Based Medical Device on Human Gingival Fibroblasts: An In Vitro Study

“…Nowadays, more and more attention is arising towards minimally invasive techniques for slowing down the aging process or improving diseases related to collagen loss. In a recent literature review, several minimally invasive surgery approaches in the improvement of facial and perioral aging were summarized, including the use of collagen [ 64 ]. For this reason, alongside the need for further studies in the dental field, it could also be interesting to investigate the beneficial effects of this injectable collagen on dermal fibroblasts to broaden its application as a dental, perioral, and facial rejuvenation treatment.…”
