My freckles and blemishes are severe. Is laser treatment okay?

After doing a few outdoor activities since summer started, my skin has turned a completely earthy color. I applied plenty of sunscreen and even wore a wide-brimmed hat, but it seems it wasn't of any use. When I looked closely in the mirror, I noticed that the freckles and blemishes around my eyes and cheekbones, which weren't there before, have become noticeably darker. My skin looks patchy overall, so my makeup just floats on the surface.

My skin tone is dull, so I feel like I look more tired and older than I actually am. Lately, I just sigh every time I look in the mirror. It seems like using whitening products doesn't really work on the blemishes that have already appeared.

If I want to get treatments for blemishes or brightening at a dermatology clinic during the summer, what kind of lasers or skincare treatments are generally best? I'm worried that getting a laser in the summer might cause more sunburn or irritation, so please recommend any brightening or tone care treatments that I can safely receive even in the summer!
