Yes! But it’s best to use lean meat, not fat. Blackheads are generally caused by hardened oil obstructions. They usually appear in areas of the face where hair follicles are densely packed, such as the nose, forehead, chest, and trunk. When the oil glands are overstimulated and the pores are filled with excess oil, causing blockage, they will appear on the tip of the nose and on the chest. The surrounding parts often feel greasy. These greases will eventually harden and become black dots after oxidation.
