Which is better: Pico Toning, Laser Toning, or IPL?

I'm really bothered by the blemishes on my face that are increasing one by one. In the past, they could be covered to some extent with makeup, but lately, the blemishes stand out more, and my skin tone seems to look dull overall.

I have noticed an increase in brownish areas, particularly around my cheekbones and on my cheeks, but I am not sure if they are just blemishes or melasma. I have been consistently using whitening products and sunscreen at home, but it seems difficult to manage existing pigmentation with home care alone, so I am looking into dermatological procedures.

I've seen a lot of procedures like Pico Toning, Laser Toning, and IPL, so I'm curious about the differences between them, and I'd also like to know which procedure has the highest satisfaction rate for removing blemishes.

I'm worried that my skin might become sensitive from a single, overly strong treatment, and I hope my blemishes fade naturally and my skin tone becomes clearer. If anyone has actually received blemish treatment, please let me know. How many sessions did you receive, what were the effects, and what were the costs and pain levels? Please give me an honest review.
