Is there anyone who takes good care of their skin? ㅜㅜ

These days, every time I wake up and look in the mirror, I sigh. Before, even if I had breakouts, they would quickly subside and disappear, leaving no trace. But now, once they're there, they just don't seem to go away. Especially when I meet friends at a well-lit cafe, I find myself bowing my head because my acne pigmentation is particularly noticeable under the lights. Even if I meticulously cover it with foundation, the characteristic dullness just won't completely disappear. People around me say time will heal it, but I see the darkening acne pigmentation, and it's incredibly stressful. I've been using vitamin ampoules and supposedly regenerative creams, but I haven't seen any noticeable changes, which is frustrating. How should I start managing my remaining acne pigmentation? If you've struggled with skin problems like mine and have found any effective home care methods or ingredients, please let me know. I'm really curious to know what routines you all use.
