As I can see on your photo, combination of fractional laser and PRP is good combination for you. If we do more agressive laser treatmant than treatment should be repeat fewer times (1-2), and if laser treatmen is less agressive, we have to repeat it more times (3-6). The agressiveness of treatments depends on recovery time you have, After light treatment recovery time is 2-3 days and you are pinky with light exfoliation of skin, and after agressive treatment recovery time is 7 days, during 7 days you are more pinky and exfoliation of skin is more intense.
Also good option for you is deep chemicall peel. Recovery time is 8 days.
