Reducing under-eye puffiness is a common aesthetic goal, resulting from fluid retention, fatigue or ageing skin. Various non-invasive methods such as carboxytherapy, mesotherapy and laser therapy are used to achieve this effect. Radiofrequency combined with synchronised targeted ultrasound is also a modern solution. This technology stimulates collagen production and improves skin condition, which can contribute to the effective reduction of under-eye puffiness. Due to its gentle action, it is suitable for use on sensitive skin in the eye area. All of these methods can improve microcirculation and lymphatic drainage, leading to a reduction in swelling and a strengthening of the skin under the eyes.
