What about facial hair?

The law lines are two lines extending from both sides of the nose, also known as nasolabial grooves. The law lines are static lines, which are caused by skin aging, collagen reduction, elastic fiber reduction, and finally skin collapse, thus forming a depression. The most common method for the treatment of law marks is the filling of hyaluronic acid, hyaluronic acid is the normal hyaluronic acid, the use of hyaluronic acid in the base of the nose filling treatment, can be a good treatment of static law marks. Some people also choose autologous fat transplantation, autologous fat transplantation needs to be treated many times, to achieve better results. Hyaluronic acid injection is relatively simple, but its disadvantage is that the maintenance time is relatively short, generally can be maintained for 6-9 months, and then need to repeat the injection treatment.
