I'm worried about freckles and scars. Which is safer and more effective, pico laser or resurfacing?

I was searching because of my facial blemishes and scars and I heard about pico laser and resurfacing treatments, so I'm considering them.

It's difficult to get a sense of the recovery period or perceived effects just by searching, so I'm curious about actual experiences.

I would also like to know about swelling and calming period, skin irritation level, cost, and treatment interval.

Those who have experience using the product, please tell us honestly about the effects you felt and the changes in your skin condition after the procedure.

I'd also like to hear expert opinions. If you could tell me the recommended number of times, precautions, and possible side effects, it would be helpful in creating a routine.

If you have had the treatment, please let me know how much improvement in skin tone, blemishes, and texture can be expected if you receive it consistently.
