Popping blackheads can indeed lead to scarring if not done properly. When you squeeze blackheads, you risk damaging the surrounding skin and causing inflammation which can result in scarring. It is generally recommended to avoid popping or squeezing blackheads and instead opt for gentle cleansing and exfoliation methods to help prevent blackheads. If scarring does occur, there are treatments available to help minimize their appearance such as laser therapy, chemical peels, or microdermabrasion.
