Carboxytherapy is a non-invasive therapeutic method involving the transcutaneous or subcutaneous administration of carbon dioxide (CO2), which stimulates microcirculation, neoangiogenesis, and collagen production. This narrative review summarizes the latest scientific findings (2020–2025) on the effectiveness of carboxytherapy in treating selected dermatological and aesthetic skin conditions, including periorbital dark circles, stretch marks, scars, and signs of skin aging. The article discusses both monotherapies and combination protocols, particularly with laser therapies and chemical peels. Numerous clinical studies confirm that carboxytherapy significantly improves skin elasticity, tone, hydration, and structure through mechanisms such as improved oxygenation, stimulation of fibroblasts, and controlled inflammation. Moreover, combination therapies frequently offer superior outcomes, especially in scar and stretch mark reduction. Carboxytherapy demonstrates high safety, minimal side effects, and broad applicability, making it a valuable tool in both medical and cosmetic dermatology.
