(Melasma and Blemishes) Skin Health / Procedure Related Question

Hello!! I am a woman in my 30s.

I usually have fair skin and tend to be free of blemishes and freckles, but

Lately, I've been spending a lot of time outdoors and getting exposed to UV rays. Maybe that's why I only apply sunscreen in the morning.

Maybe it's because I haven't been reapplying it, but I feel like my freckles, blemishes, and red bumps are coming up.

Would laser be effective for this type of treatment?

What kind is available?
