I used to have this, I'm not a professional but they might be closed comedones. You can go and see a dermatologist or a certified professional to get extraction done (they normally help you squeeze out the gunk buried underneath the skin), it normally works very well for me even though people always say don't pop them ๐ But they never go away on their own
For products, have you tried any tea tree products? If you're using any skincare at the moment, please check if they are non-comedogenic products / fungal-acne safe โจ
P.S. It could also be a diet problem or if you've been under a lot of stress.
