Popping blackheads can be harmful as it can lead to skin irritation, infections, and scarring. When you squeeze or pick at blackheads, it can push the bacteria and oil further into your pores, causing inflammation. It’s important to use proper techniques and tools if you choose to extract blackheads. However, it’s generally recommended to seek professional help from a dermatologist or esthetician to safely remove blackheads.
