I have tested a ridiculous number of beauty products, and these 15 are the ones I still buy with my own money. No one-week trend picks here: it is the lip mask that lives on my nightstand, the moisturizer I go back to when my skin is angry, the exfoliant I trust after every failed experiment, and the body cream people stop me to ask about. I split the list into skincare, makeup and hair so you can jump straight to the part you need. If you are starting from zero, buy the moisturizer, the exfoliant and one good lip product, then build from there.
