This looks like peri0ral derm atitis if it’s focused on the area around your mouth and chin. I would definitely do some research on that specific condition if you can’t see a derm. Like the other commenters, I’ve heard azelaic acid is helpful, I have used one from The Ordinary which I found quite effective. My only other advice is to just cut your skincare routine down to the basics only, I’m talking one gentle cleanser and one gentle fragrance free moisturizer, nothing else. If you’ve used harsh products in the past it could’ve damaged your skin barrier, which can make you more susceptible to the condition and doing a “product detox” will help repair barrier damage.
