This is the only blemish crème/serum that works for my pre teen son’s stubborn blackheads on his nose. As soon as his hormones started changing around 11-12yo his nose area was a hot mess. It felt like it happened overnight. I had a bottle of this on hand, but hesitated to have him use because of the price so I first tried several OTC options, biore strips, and a handful of other teen acne serums SunnySDSD · lovelyskin.com
