don’t colour your eyebrows in. don’t fill them with a pencil, don’t draw them on thicker, please please i am begging you. it doesn’t work. it’s just really obvious that you’re wearing makeup (if you want to wear makeup by all means, do you. this isn’t about that tho, this is for those who want a natural look)
instead, find eyebrow/lash dye/tint or a really basic mascara (no lengthening or whatever - waterproof is good though). make sure it matches your natural hair colour or is just a little darker. don’t go for jet black unless you actually have black hair, it’ll look fake.
use that instead. only colour the hairs, not your skin. try to get all the little hairs. done. dye is good because you don’t have to reapply it every day! but if you use mascara use it lightly & try brushing your brows around a bit so they don’t look too neat.
it’s a lot more subtle and i promise will masculinise your face more effectively than pencilling on unnaturally thick brows.
