Does the effect of Pico Toning last a long time?

Lately, every time I look in the mirror, my bare face looks so dull because of the freckles and blemishes that I really don't want to look in the mirror.

I looked it up and heard that Pico Toning is less irritating to the skin and is the most famous among toning treatments, so after much consideration, I’m planning to give it a try.

But since I'm a complete beginner with no experience with cosmetic procedures, I have a lot of questions regarding the effects and how they last!

How many Pico Toning treatments do I need to see visibly faded blemishes? I am also curious about how long the effects last after just one session. Some people say that to see proper results and maintain them for a long time, you need at least three consecutive sessions for your complexion to gradually brighten; how should the first treatment cycle usually be scheduled?

I am very timid and have sensitive skin, so is it very painful when the laser is applied? I am worried that my face might break out or the redness might last a long time after the procedure, so I want to know if it is safe to go to work or resume daily life immediately.

I would be really grateful if you could share some precautions or honest reviews so that a beginner like me, who knows nothing about skincare, doesn't fail at my first Pico Toning treatment! Please help me.
