For those of you who have received Pico Toning, how were the results?

I'm really stressed out these days. Every time I look in the mirror, I feel like my skin tone isn't what it used to be, so I've been looking into various options. I'm particularly bothered by the fine blemishes and how my skin looks dull overall. While searching online, I saw a lot of talk about Pico Toning, so I became interested. It seems like Pico Toning is popular for treating melasma and blemishes, but I'm curious to hear from those who have actually tried it. I've heard that you need multiple sessions to see results, and that results vary from person to person, so it's hard to make a decision right away. If anyone has tried Pico Toning, please let me know about the cost, treatment frequency, and satisfaction level. Since my skin tends to be sensitive, I'm also curious if you experienced any redness after the treatment. Since it's my first time trying it, there seems to be more to research than I thought.
