Inquiry regarding treatments for melasma and blemishes

I am stressed because my freckles and blemishes seem to get particularly darker every summer due to the strong UV rays. Are there any effective dermatological treatments available during this time? I have only had Pico Toning so far, but I would like to try a variety of treatments this time.

People around me have recommended laser toning or Clarity for blemishes, and I am curious about the specific differences between the two procedures. If I receive laser treatment during the summer, will the irritation become too severe, causing my melasma to darken or leading to side effects?

I would also like to know if combining laser treatment with other treatments, such as vitamin care or skin Botox, can create a synergistic effect by soothing sun-damaged skin and aiding in whitening.

I would be very grateful if you could also provide detailed information on precautions to follow in daily life and home care tips after the procedure!
