How many sessions is usually recommended for treating adult acne that remains red?

Hello~ My breakouts suddenly got worse a while ago, and even after they subsided, red marks remained patchy all over my face, which is really stressing me out ㅠㅠ!! I try to cover them up with makeup, but they don't hide well, and my skin looks tired overall~ I feel like there are limits to managing this on my own with just cosmetics, so I'm planning to start a professional acne treatment program at Maypure haha! I'm curious how many sessions are typically recommended for acne treatment when the problem is mainly red marks and small breakouts like mine!! I would be grateful if those of you who have experienced this could share some tips on how often I should schedule my visits to see noticeable changes in a short period of time~~!
