Washing your eyebrows is like washing a tattoo. It always hurts a little, so there is no painless eyebrow washing machine at present, but usually you will be given some anesthetic before washing your eyebrows, so you won't feel any pain when cleaning your eyebrows. Nowadays, laser eyebrow washing is widely used, and of course, picosecond eyebrow washing is also available. It is suggested that you must choose a regular plastic surgery hospital to do it.
