It is common to see women using threading and waxing for removing the upper lip hairs. It is obvious that hair removal is necessary to look attractive. As a matter of fact it is unfeasible to stop these medium of hair removal completely. However, the regularity can be controlled. Excess of waxing makes the skin to loose its elasticity. Once the skin elasticity is lost over the period of time it causes early formation of perioral lines around the mouth.
Similarly the cotton thread used in threading is moved giving twisting strokes to pull out the hair on upper lips. This too makes the skin sag and gives way to lip wrinkles.
