Is vascular laser the surefire way to treat red acne scars? ㅠㅠ

After a massive bout of cystic breakouts swept through my face a while ago, I'm left with really messy redness and tiny marks, just like in the photo of my cheek ㅠㅠ. Even if I cover them meticulously with concealer, they don't hide them completely, and when I look barefaced, they look totally blotchy and unsightly haha. I heard that a vascular laser, which selectively destroys only the redness, is the best for getting rid of these red scars. If I get the treatment when the marks are as severe as mine, will my skin really turn completely white, like a peeled egg? I'm curious if they definitely fade after about 10 sessions, and I'm really worried about severe bruising or swelling after the procedure ㅠㅠ. To those who have successfully gotten rid of red acne scars, please leave some vivid advice on what kind of laser treatment you received at the dermatology clinic!
