I have been struggling with acne for several years. It isn't just a brief breakout like during puberty; even now as an adult, the pattern repeats: breakouts mainly on my chin and cheeks appear, subside, and then reappear. My skin type seems to be dehydrated oily-oily, as it is shiny on the surface but feels tight underneath, and breakouts flare up immediately at the slightest sign of fatigue. I have tried various highly-rated cosmetics, but choosing products is incredibly difficult because they seem fine at first, only to flare up again at some point. In particular, before my period or when I am stressed, I even get inflammatory acne that is difficult to cover up with makeup, which significantly lowers my self-confidence. I am paying attention to my cleansing, basic skincare, and lifestyle habits, but I feel frustrated because there hasn't been any significant change. I would appreciate any advice from those with similar skin types who have seen results with specific care methods or products, or those with experience with medical treatment.
