Concern about dark spots and blemishes

I've been worried about freckles and blemishes on my skin for a long time.

Maybe it's because of the hotter weather lately, I feel like it's gotten thicker.

Even when I apply sunscreen well, dark spots and blemishes still tend to appear.

I heard that it would be good to receive laser toning.

It seems I should receive a lot.

How long does it take for the effects to appear?

Would you recommend those who have tried it?
