I get bothered by the black-looking pores beside my nose, so I end up holding the mirror closer and closer. Online, reviews like “premium extraction treatment” · “dissolve it with toner” · “one bottle of medicine is enough” all pop up at once, and it’s hard to tell which path is really right.

To start with the conclusion, blackheads have different timelines depending on the month. Squeezing gives the biggest immediate change, but they fill back up the next month; salicylic acid toner may show only small changes this month, but after two months the pores fill up less. tretinoin is hardest in the first two or three months, and after that the pores themselves become calmer. If you use different treatments on the same spot, the results visible a month later can be completely different.

Blackheads are a matter of time, not pores

Blackheads are what happens when sebum and dead skin cells clump together inside the pore and turn black through oxidation after meeting the air at the surface. It’s not dirt or dust stuck in the spot; it’s normal sebum that couldn’t come out and oxidized instead. That’s why they come back in the same place even after you clear them once.

Areas with many sebaceous glands, such as the sides of the nose, the chin, and the center of the forehead, produce new sebum every day. If you only squeeze to empty them in the moment, they’ll fill back up by the following week. That’s why you need to look at immediate changes and one-month changes separately to see the timeline.

Squeezing: fastest on the spot, but it fills back up within a month

Comedone extraction is the fastest way to clear the black dots right then and there. Dermatology extractions are handled more hygienically and tend to leave fewer marks, but if you squeeze at home with your hands or tools, irritation, redness, and post-inflammatory hyperpigmentation can follow around the pores. After squeezing, the area often looks better for a while, then fills back up with sebum in the same spot.

If the extraction itself is repeated more than once a month, many people end up with enlarged pores. So it’s better to think of extraction as emergency care and leave the routine care to medication. Right before a big event like a wedding or interview, squeezing may be worth considering, but squeezing the same area every week can work against you by enlarging the pores.

Salicylic acid toner: pores fill up less over a two-month period

Salicylic acid* is a BHA ingredient that dissolves well in oil, so it can reach deep into the pores and slowly break down dead skin and sebum. Toners and serums with 0.5–2% concentration are the most common, and when used daily or every other day for about 4–8 weeks, you begin to see that the pores fill up less. You may not feel much change in the first month.

It tends to be much less irritating than tretinoin, but some people experience tingling, flaking, or a bit of dryness when they first start. If using it every day feels like too much, start every other day and increase to daily after about 4 weeks once your skin adjusts. Keep up your moisturizing step, and make sure to use sunscreen as well so irritation doesn’t build up.

Salicylic acid*: a BHA ingredient that dissolves well in oil and helps exfoliate the skin. It loosens sebum and dead skin inside the pores, so it’s often used for blackhead care.

Tretinoin: after the first two to three rough months, the pores become calmer

Tretinoin is a prescription vitamin A derivative that speeds up cell turnover inside the pores, changing the environment that allows blackheads to form in the first place. It is often started at 0.025%, and in Korea it is available by prescription only.

But the first two to three months after starting are usually the hardest. As what has been building up inside the pores comes to the surface all at once, a temporary purging phase often appears, making acne and blackheads look worse. If you get through this period, many people find that the pores themselves become calmer afterward. If using it every day feels difficult, start about three times a week and slowly increase the frequency. Because it increases sun sensitivity, sunscreen must be used even more carefully, and it should not be used during pregnancy or when planning pregnancy.

How to set your plan on a one-month timeline

If you want to see change within a month, extraction is the fastest option, but the pores will fill back up within that same month. Over a two- to three-month period, salicylic acid toner gradually keeps the pores from filling as much. If you want to calm the pores themselves over six months or longer, tretinoin is usually the clearest option.

Rather than using all three at once, it’s gentler to space them out by timing. A common approach is to maintain with salicylic acid toner, clean things up with extraction about once a month, and add tretinoin after a doctor’s consultation if the pores themselves are still a concern. This article is a general information summary, and any treatment plan that takes your skin’s irritation level and sensitivity into account should be decided with the doctor who examines you in person.
