Mediheal Blackhead Melting Patch Effective?

Is it good for blackheads? Probably. But what you might actually have are sebaceous filaments, and if you extract them basically you’ll enlarge your pores and make them worse.

You can’t actually get rid of sebaceous filaments forever, only thing you can do is keep them “clean”. And that is by using a cleanser after or while you shower (when the pores are open) with warm water, then rinse with cold water.
