How long does it take to see the full effects of Pico Toning?

Lately, the freckles and blemishes on my face seem to be getting darker, so I worry a lot every time I look in the mirror. Even though I make sure to apply sunscreen regularly and use whitening cosmetics, I don't see any improvement, so I started looking into cosmetic procedures. Many people around me have also recommended Pico Toning, so I have become interested.

For those who have actually received the Pico Toning treatment, I am curious how many sessions it usually takes for the effects to appear. I would also like to know if it is effective for managing patchy melasma and blemishes, and what the recommended visit schedule should be.

If anyone has experience with Pico Toning, please share your honest review regarding any pain or side effects!
