Eyebrow threading is an ancient hair-removal technique, practiced for centuries among the most beautiful women of Asia and the Middle East. It is the best alternative to waxing and tweezing, especially for sensitive skin. Unlike waxing, threading does not remove a layer of skin, which can leave the skin on your face susceptible to sun damage. By far the least invasive method of facial hair removal, this method creates a graceful brow with clean, well-defined edges that frame the eye.
