Lip augmentation and remodelling is a cosmetic treatment with dermal injectable fillers that provide thick lips, reshape them, make them firmer or turn the corners of the mouth upwards. The most recommended lip fillers are usually hyaluronic acid, a component that provides volume and stimulates collagen production, or the patient’s own fat tissue, which is previously extracted and purified. Both types of fillers give a natural and immediate effect after being injected. However, as the body reabsorbs these substances, the effect gradually diminishes over time. Normally, its duration is between six months and one year, but may be repeated afterwards.
