Simple>Hole has something dark in it
Dirt, ingrown hair, or more than likely blackhead>Hole has something white in it
Dandruff or other skin flakes lodged in. could also just be excess sebum of whatever that thin oil your skin over-produced is called. If the skin around it is inflamed, it is actually a whitehead, which can eventually become a pimple or cyst. I wouldn't fuck with it until it becomes one of those and even then, proceed with caution, maybe follow >>61510275
As for how to know if it is just a scar or pore instead?>Hole exists, but you can't see deep enough to see what is in it
Probably just a pore you were rubbing too much. Should look better after a day of no pressure>Hole exists and is deep, but nothing red, black, brown, or white is visible.
Skin pit. Probably just a scar that got ripped off early or where a cluster of acne once formed but has not formed in quite some time>Hole is empty, but the are around it is inflamed
Normal pore that is recovering from a rash or acne that you got rid of. Keep it clean and cool, but don't fuck with it until the inflammation is down.
Basically, your pores are small or big. The bigger they are, the easier it is to get acne, but the easier it is is to remove the acne. The smaller pores are not as likely to develop acne, but if they do get acne, they take longer to recover and to get the acne out. Over time, our pores tend to get larger. Also, the temperature of our body plays a small role in the size. When you are really cold, your pores will shrink just a bit, but when you are really hot and sweat, the pores enlarge a small amount.
Lastly, please keep in mind that noses have less fat than the rest of your face and also use cartilage and stuff so, despite your pores looking a bit different there, it does not necessarily mean your nose is full of blackheads. If the rest of your face has a similar texture to the nose, it means you probably have some mini black heads (can be rolled out easily).
