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.
