Is it okay to get laser toning for acne scars in the summer?

I am worried because my melasma and blemishes have darkened rapidly due to strong UV rays from frequent outdoor activities this summer. The dark scars left over from past acne haven't completely faded yet, and perhaps due to the excessive sun exposure, dull pigmentation has suddenly flared up on my cheekbones. My overall skin tone looks patchy and dull, making me feel very self-conscious about going out without makeup. I have tried using brightening essences and am diligently applying sunscreen, but the pigmentation that has already settled isn't fading easily. I want to restore my skin to a clear and radiant state, so I am wondering what types of toning or laser treatments can safely treat melasma and blemishes during the summer without causing skin irritation or side effects.
