there is one way that works without stupid makeup. embrace your looks and be proud of it. people will notice you´re confident and that will instantly boost your attractivenes more than any makeup ever could.
Makeup. Moisturizer, primer, concealer, foundation, bronzer, blush, eyeliner, eyeshadow, brow liner (if needed), mascara (+ maybe fake lashes), and a flattering lip color. Also, I would style her hair (probably straight, or straight with some curls).
