Does the Pico laser really work? I'm curious if it's worth the money.

I'm considering getting a Pico laser because of blemishes, light melasma, and a dull skin tone.

I’ve heard a lot of people around me say their skin became clearer after getting Pico laser treatment, so I’ve become interested, but the price is quite steep, so I can’t easily make a decision.

The hospital says it helps improve blemishes, freckles, and pigmentation, but looking at the reviews, some people were satisfied after just one or two treatments, while others said they didn't feel as much of a difference as they expected even after multiple sessions, so I'm confused.

My main goal is to improve my skin tone, and I am curious if there will be a change significant enough to make my skin look cleaner when I actually wear makeup.
