Causes, Symptoms and Treatment
Laugh lines are wrinkles or creases in the skin of a person's face that appear around the outer corners of the mouth and eyes. The lines are most visible when a person smiles or laughs which is where the name comes from. Laugh lines are most commonly caused by a natural decrease in collagen and elastin in the skin. Repetition of facial movements, including frowning, smiling, laughing and any other facial expression are also contributing factors. Smoking, sun exposure, genetics and ageing also play a part.
Dermal Fillers such as Juvederm and Restylane which contain Hyaluronic acid can be used to lift these lines back up and can look completely natural. Most commonly the crease from the nose to the corners of the mouth are injected and filled out. They also replace the appearance of volume loss that occurs with ageing.
Anti ageing injections work to prevent laughter lines by relaxing the muscles in the face.
