Upper Lip Threading is more superficial than waxing, which means you may find the hair may grow back quicker. However many people find that waxing the upper lip can cause a reaction as it’s a more sensitive area.
The reason why threading is ideal for all skin types is because the pressure of it can be adjusted accordingly.
In threading, a thin (cotton or polyester)thread is doubled, then twisted. It is then rolled over areas of unwanted hair, plucking the hair at the follicle level, unlike waxing threading just removes the hair with no damage to the skin.
