I'm curious about the causes of blackheads and how to effectively manage them.

Regarding blackheads that are darkly embedded around the nose,

I'm curious as to what causes these blackheads and why they appear especially often on my nose and T-zone.

According to the results of my research, the cause of blackheads is that excessive sebum mixes with dead skin cells to block pores, and the tips turn black when they come into contact with air and oxidize.
In particular, the nose area has developed sebaceous glands, so it is said to develop more easily than other areas.

I want to fundamentally resolve the cause of blackheads, but I feel like it's difficult to manage them with daily home care.

Therefore, I would like to inquire about what kind of treatment or management the clinic recommends to address the cause of these blackheads and remove them cleanly.
I heard that it can recur if sebum secretion continues even after the procedure.

If there are any management or precautions that are good to take in conjunction with the treatment to maintain the treatment effect for a long time and eliminate the cause of blackheads, please let me know.
