I have rubbish sparse eyebrows and have kept the eyebrow pencil market afloat for years. But in this weather they smudge and move. Wonderbrow in absolutely epic. I love it. Whack it on with a lipstick brush and it lasts for days if I don't wash it off in the shower.
I epilate my bikini line which works well but I've had awful ingrown hairs. Recently started using Tend Skin after reading a BuzzFeed article. Smells heinous but by god it works.
Neither very exciting but immovable natural eyebrows and a smooth bikini line are a joy.
