Nasolabial fold treatment is offered to patients with smile lines at the Eden Institute of Plastic and Cosmetic Surgery. Non-permanent injectable fillers such as collagen or Restylane may be used to lift and soften 'smile lines' - these run from the nose corners to beside your mouth. The treatment results in swelling which lasts from 1 - 3 days, and may incur some bruising that is easily camouflaged. It is best to have this treatment at least two weeks prior to any special event.
