I'm concerned about facial pigmentation. Is laser treatment the answer?

As I age, my facial pigmentation has become noticeably more pronounced, and it's causing me a lot of stress. I always thought I applied sunscreen diligently, but the patches of pigmentation around my cheekbones and mouth don't seem to be improving with home care alone. Every time I look in the mirror, my complexion looks dull, and makeup doesn't seem to be able to hide them, which is a huge concern. I feel like I need professional help, so I'm researching dermatological treatments for facial pigmentation. I'm curious about how effective toning and peeling treatments are in improving facial pigmentation. Will these treatments be effective for deep-seated blemishes and scars like mine? Could you also share with me some detailed post-treatment precautions and how long the treatment will last with consistent care? My skin is sensitive, so I'd really like to find a treatment that's gentle on the skin while still being effective.
