I'm even paying attention to my diet, but I still have these bumps on my forehead ㅠㅠ Looking for tips to get rid of these tiny pimples haha

Hello everyone. Did you all have a delicious dinner? Lately, I’ve been trying to take care of my health, so I’ve been cooking healthy meals with plenty of scallops and celery, drizzling lots of good olive oil. Haha. I’m taking care of my insides like this, but I’m so upset that these bumpy, unwelcome guests have shown up on my forehead and chin, so I’m leaving this post. Haha. I’m really stressed out, so I’m hoping to get some great tips on how to get rid of these tiny pimples.

At first, I thought it was just a temporary breakout due to the change of seasons, but it hasn't shown any signs of subsiding for days, and since makeup can't cover it up, I get angry every time I look in the mirror ㅠㅠ My forehead used to be really clear, so I have absolutely no idea what's causing this sudden flare-up. Is there anyone here who experienced a sudden breakout like me and successfully got rid of all those tiny bumps? I have no idea if I need to go to a dermatologist to get them all extracted, or if it's because I haven't been exfoliating properly at home haha.

I heard that it might be because the cleansing oil doesn't agree with me, so I'm considering switching to a water-based or milk-based cleanser. Is it really effective to wipe my face with a toner containing BHA or AHA during my skincare routine to get rid of small bumps? I haven't been able to try it yet because I'm afraid it might be irritating.

I keep scratching at them with my hands and I'm afraid I'll get scars, so I'm forcing myself to hold back. If any of you have any effective ointments or skincare routines for getting rid of these tiny bumps, please, please share them with me lol. I really want to get rid of all these bumps quickly and go back to having smooth skin like before ㅠㅠ Please help me, experts!!
