My skin pigmentation has gotten worse. How can I manage it?

Lately, I've been worried about my uneven skin tone and pigmentation. Perhaps it's due to sun exposure, but they keep appearing like spots, and I'm concerned every time I look in the mirror. Home remedies seem insufficient to completely remove pigmentation, so I'm looking into hospital treatments. I've heard that pico-toning and laser treatments are helpful, but I'm curious if they're actually effective in improving pigmentation. I'd also like to hear from you about your experiences and whether consistent treatment can improve it.
