Skin Boosters: 2026 Updated

Abstract

Skin boosters are increasingly used to improve dermal quality through injectable and device-assisted approaches; however, definitions and clinical evidence remain heterogeneous. Aims: To provide an updated overview and propose a practical classification of skin boosters, including mechanisms, delivery methods, clinical outcomes, and limitations. Patients/Methods: A narrative review of recent literature on injectable and device-assisted skin boosters, including hyaluronic acid, biostimulatory polymers, calcium hydroxyapatite, polynucleotides, platelet-rich plasma, exosomes, and emerging agents. Results: Skin boosters improve hydration, elasticity, texture, fine lines, erythema, and dyschromia with generally favorable safety profiles. Mechanisms include hydration, neocollagenesis, elastogenesis, angiogenesis, and anti-inflammatory effects. However, evidence remains limited by heterogeneity and lack of standardized protocols. Conclusions: Skin boosters represent a promising modality for skin rejuvenation, but further standardized clinical studies are required.
