Blackhead strips are especially designed to get rid of excess of oil and sebum on the skin while also getting rid of the small black bumps present. These can be used on the nose, forehead, chin and in some parts of the skin. In these strips, there is a coating of glue on one side. This glue is the main component that binds to the dirt and sebum on the skin. Once the pore strip dries out, it is pulled off, thus, peeling the blackheads and oil with it.
