I would like to inquire about freckle removal treatment.

Lately, I've been looking into dark spots on my face, so I'm looking into dark spots removal treatments. Makeup doesn't seem to be covering them well, and my skin tone looks dull overall, which is a major concern. I've tried using whitening products at home, but I haven't seen much effect, so I'm considering a treatment at a hospital.

There are many treatments like pico laser and IPL, but I'd like to know how each method of removing freckles differs and which one is best for my skin type (combination and slightly sensitive). I'm also curious about the severity of redness and stinging after the procedure, and whether it will interfere with my daily life.

Could you please tell me how many sessions I need to see noticeable changes and how long they should last? If there are any products or treatments that would be more helpful to use at home, please let me know about those as well.
