The act of removing blackheads is not considered haram in Islam.
Blackheads are a common skin condition that does not affect one's health or religious practices.
Removing them is considered a matter of personal hygiene and aesthetics, similar to other practices like trimming nails or removing hair.
However, it is important to note that any procedure involving the skin should be performed with care and cleanliness to avoid infections or complications.
It is important to consult with a qualified medical professional for any concerns about skin health or treatment.
