I'm so upset because of the acne pigmentation I see every time I look in the mirror.

These days, every morning, after I wake up, wash my face, and look in the mirror, I sigh. It used to be that my skin troubles would disappear without a trace within a few days, but that's not the case anymore. The acne scars around my cheeks are especially noticeable, so I find myself reapplying concealer multiple times. The more I apply makeup, the more my skin looks dull, and it's incredibly stressful. I diligently practice home care, even applying vitamin ampoules, but the deep-seated acne pigmentation doesn't seem to fade easily, which worries me. I seriously consider going to a dermatologist, but the cost and time involved often make me hesitate. Do you have any products or lifestyle habits that have proven particularly effective for managing persistent acne pigmentation like mine? Or, if you have any recommendations for treatment methods, I'd love to hear your valuable tips.
