Profhilo is an innovative anti-ageing treatment developed by a medical and pharmaceutical company based in Switzerland. It was approved for use in Europe in 2016, with the UK being one of the first countries it was introduced to. Profhilo is injected into the skin to improve hydration and promote collagen growth, two key elements that are important in maintaining healthy and youthful-looking skin. At its core, Profhilo works by rehydrating the dermis (the deepest layer of your skin) using hyaluronic acid molecules, which act like a sponge to attract and retain moisture within the skin.
