Profhilo, also known as the injectable moisturizer, is a buzzy new skin procedure that promises to rejuvenate the skin. The treatment involves injecting hyaluronic acid into the face, allowing a slow release into the epidermis to stimulate collagen and elastin production. Unlike fillers, Profhilo diffuses into the skin to boost your complexion instead of staying in one area to plump cheekbones or fill creases. For maximum results, experts recommend two treatments four weeks apart. Individuals report that the effect lasts up to 28 days but the benefits continue whilst the collagen supply is stimulated.
