Aesthetic and reconstructive demands increasingly intersect with regenerative technologies, offering enhanced results with minimal invasiveness. Tissue engineering in cosmetic surgery incorporates scaffolds, growth factors, and autologous cells to improve skin texture, volume, and contour. Applications range from engineered dermal fillers and bioactive matrices for facial rejuvenation to cartilage scaffolds used in rhinoplasty or ear reconstruction. These techniques not only enhance cosmetic outcomes but also promote functional restoration in post-traumatic or congenital conditions. Tissue engineering in cosmetic surgery also emphasizes biocompatibility, reduced scarring, and accelerated recovery through bioengineered support systems. As patient expectations evolve, combining precision regeneration with surgical artistry is reshaping the future of aesthetic medicine.
