Plucking can make your eyes look larger and give your face a clean, polished look.
Eyebrow plucking tips to help you achieve beautiful eyebrows. Eyebrow plucking should ideally be timed just before hitting the sack as the sleep time that follows allows any subsequent redness to disappear overnight. Slant edge tweezers, which grip hairs easily, are best for shaping brows while combing hairs one way, then the other, helps remove loose strands. When plucking, pluck the stray hair underneath the eyebrow - not above the eyebrow.

Plucking Eyebrow Tips :
Sit near a window to get the best light.

Use a pair of angled eyebrow tweezers to pluck the hairs below the brow; never shape

your brow by plucking above it. Pluck only one hair at a time.

A tweezer with a pointed or slanted tip will grip the hairs best.

Be careful to pull the hair, not the skin when tweezing. While its easy to accidentally grab the skin, doing so may result in redness or bleeding. If redness does occur, rinse your face with cold water and apply a cold eye mask to soothe the flushed skin.

Always pluck below the brow line, so the hair coming back will follow the natural arch of your brow.

Wash the area thoroughly so it's not oily.

Afterwards use a cotton ball or pad soaked in pure tea tree oil or witch hazel to soothe your plucked brows.

There are tweezers on the market that are specially designed for plucking eyebrows. They cost a bit more but make the experience less painful.
