My acne has subsided but red marks remain. Should I get Excel V? ㅠㅠ

After a bout of cystic acne swept through, I'm left with really messy redness and marks on my cheek, just like in the photo ㅠㅠ Foundation covers them up somewhat, but when I look bare, it's so blotchy and unsightly lol. I heard that vascular lasers like Excel V or V-Beam are good for getting rid of these red marks; if I get them while I have a lot of fine redness like me, will my skin really turn completely white, like a peeled egg? I'm so confused whether alternating with toning would create a synergistic effect, or if it would be better to get a skin booster to reduce redness as well ㅠㅠ To those of you who have successfully gotten rid of red acne scars, please leave some vivid, genuine advice on what treatments you mainly received at the dermatology clinic lol
