Is there anything that heals gently without causing irritation or oozing?

I want to get rid of the acne marks remaining on my face. I have received laser treatments a few times before. However, every time I received a treatment, my face would turn extremely red as if it were on fire, and the irritation was so severe that it even caused oozing. Even though I endured it with difficulty and went through with it multiple times, I didn't see significant results in filling in the dark spots or pitted scars, so I stopped treatment midway. I felt like my skin had just become more sensitive, so I took a break for a while, which was very upsetting. That is why I am planning to start proper treatment again this time. I am wondering if there is a gentle treatment method that can help clear up red and dark marks and fill in pitted areas without causing excessive irritation or oozing like before.

Considering my skin condition and scar depth, please let me know in advance how many treatment sessions would typically be necessary and if you have a recommended program structure.
