Hyaluronic acid injections have gone from niche cosmetic procedure to social-media staple, and this DW film follows the people on both sides of the needle. Alessa Book, from East Frisia in northern Germany, decided she wanted a fuller upper lip after seeing before-and-after ads online, and the film follows her to a doctor's office for a 300-euro treatment. Elsewhere the story turns darker: German law restricts hyaluron injections to doctors and licensed alternative medicine practitioners, but a booming gray market of untrained injectors has drawn police investigations and left patients with botched, sometimes dangerous results. Doctors and regulators explain what can go wrong when filler is injected by someone without medical training, from vascular occlusion to disfigurement, while clinics defend the procedure as safe when properly administered. The film moves between consultation rooms, clinics, and the online advertising that drives demand, building a picture of an industry expanding faster than oversight can keep up. It treats the substance itself as neither villain nor miracle, just an active ingredient whose growing normalcy is reshaping faces and raising questions about who gets to wield the needle.
