Closed comedons help😭

English isn’t my first language, so i hope i can explain this clearly. I have little tiny bumps on my skin and they’re most likely closed comedones. Right now I’m using Anua’s azelaic acid serum along with the other products in my routine. After having long conversations with ChatGPT and Gemini lol, they recommended products like cosrx BHA that won’t strip my skin barrier too much but could still be effective. What do you think I should do or buy pls helpp^^
