Blackheads are a type of acne characterized by small bumps on the skin that form when hair follicles become clogged with oil and dead skin cells. When these clogged pores are open at the surface, they appear black due to oxidation, hence the term blackheads.

Blackheads can be quite common, especially in areas like the face, where the skin produces more oil. While it’s possible for blackheads to refill if the pore is not properly treated or cleaned, proper skincare practices can help prevent them from reoccurring. Regular cleansing, exfoliation, and using products like salicylic acid or retinoids can help keep blackheads at bay.

If you are concerned about persistent blackheads, it’s a good idea to consult with a dermatologist for personalized advice and treatment options.
