Hydrocolloid pimple patches that draw out the pus of whiteheads. They also worked on red bumps i had by flattening them overnight. They have to be worn for at least six hours so overnight is a good option. A new one can be used on the same pimple during the day. The star shape makes it easy to pick up and remove because you can handle them by a point. They are cute and can be worn in public. The rainbow ones i have support blm and trans people charities. Each star has a different striped pattern. They also come in different shapes, colors and characters. They have a reward program where you can earn points for buying from their website and taking certain actions.
