ProsI find it's great to use once a week on the T-zone when you've got a lot of blemishes or blackheads on your nose. It seems like using it too often might irritate the skin, so I stick to once every 7-10 days.
ConsIf you leave it on for more than 20 minutes, it can feel a bit irritating. For those with super sensitive skin, it's probably best to keep it to 10-15 minutes.
