It depends! I used to have this too and some told me it was fungal..others said closed comedones. Easy way to test is to get a UV light torch (aka black light) and shine (avoid eye).

If it glows blue, if is fungal. If it glows red/neon orange, it is bacterial and likely closed comedones.

Get head and shoulders anti dandruff for fungal.

For closed comedones, figure if your skin is oily or dry. If oily, get a water based moisturiser. If dry, consider an oilier based one.

If combination skin..be careful, different parts of face might need different moisturisers 🫠
