It seems like pigmentation is more visible as the seasons change.

I am concerned because the hyperpigmentation on my face seems more noticeable than before, perhaps due to my skin becoming drier and more sensitive as the seasons change. I didn't usually pay much attention to it, but lately, my skin tone looks uneven, and melasma and blemishes seem particularly dark. Since consistent moisturizing doesn't seem to be making much of a difference, I am looking into dermatological procedures. I am wondering if treatments like Pico Toning are effective for improving hyperpigmentation. I would also like to know if the appropriate treatment varies depending on skin condition, and how many sessions are typically required to expect noticeable results. I would appreciate it if you could share satisfaction levels and aftercare tips from those who have actually received the treatment, as well as whether it is safe to get it done during the changing seasons.
