Tear through correction thru direct collagen fillers, the old - new

Objectifs: This lecture aims to evaluate the role of collagen-based injectables in tear through rejuvenation, with emphasis on their clinical applications, aesthetic outcomes, safety profile, and emerging role in regenerative aesthetic medicine. Particular focus will be placed on treatment efficacy, patient selection, injection techniques, and the potential advantages of collagen-based therapies in minimizing adverse effects within the delicate region. Introduction: The periorbital region is one of the first facial areas to show signs of aging due to its thin skin, limited structural support, and constant movement. Aging, genetics, and ethnic factors contribute to fine lines, skin laxity, volume loss, and tear trough deformities. While conventional treatments such as HA fillers and energy-based devices are effective, they may have limitations in this delicate area. Collagen-based injectables offer a regenerative approach by enhancing dermal quality, stimulating collagen remodeling, and restoring tissue integrity with a more natural-looking results. Matériels / méthode: This lecture reviews current literature and clinical evidence regarding the use of collage. Topics include the biological properties of collagen, mechanisms of action, regenerative potential, patient selection criteria, treatment protocols, and injection techniques. Particular attention is given to the biostimulatory effects of collagen, its influence on dermal remodeling and neocollagenesis, and clinical outcomes related to skin texture, elasticity, hydration, and overall periorbital appearance. Safety considerations, complication avoidance, and management strategies are also discussed. Résultats: Reported clinical benefits include: Reduction in fine periorbital rhytides Improvement in skin firmness and elasticity Enhanced dermal hydration Improved skin texture and luminosity Softening of tear trough deformities Natural-appearing rejuvenation without excessive volumization When administered using appropriate patient selection, injection depth, and technique, collagen-based injectables demonstrate a favorable safety profile characterized by minimal downtime, low rates of edema, and a reduced incidence of delayed complications compared with traditional volumizing fillers. Conclusion: Collagen-based injectable therapy represents an evolving and promising modality for tear through rejuvenation, addressing the structural and biological mechanisms underlying facial aging. By promoting tissue regeneration and dermal remodeling rather than relying solely on volumization, collagen injections offer a minimally invasive approach capable of achieving natural-looking and sustainable aesthetic outcomes.
