Alvi Prague's carboxytherapy changes the skin’s pH and triggers physiological reactions without physical intervention. During the procedure, a specific device and products are used to create a controlled oxygen deficiency by increasing the level of carbon dioxide in the epidermal tissues. This stimulates the body’s natural response, boosting blood circulation and oxygen levels in the tissues, which enhances collagen production. As a result, the skin becomes firmer, wrinkles are smoothed, pigmentation is reduced, and acne is treated and prevented.
