First of all, I'm really sorry for my English. I'm currently 18 and suffering from acne scars

I've suffered from acne started when I was 12 (not cystic, it's like whiteheads, blackheads, and sometimes pimple) and I don't really have many acne right now, they just show up in some spots and they rarely show up.
Anyway, so I'm suffering from the scars that are left from the acne. Now I'm not sure if the scars just showed up naturally or what, but back in 2016 I applied azelaic acid on my acne which mostly are whiteheads, blackheads, and some pimple on some spots. And the azelaic did clear my skin, so I would just apply it for 3 months even though the acne had gone just to make sure that I've got rid of them. But somehow, I guess the azelaic cream left me some scars on the spots where I applied to. I mostly applied it on the temple cause that's where the whiteheads and pimples showed up.
The scarring I have, maybe they're ice picks. What kind of treatment would you suggest me? However, I'm really interested in the treatments of Dr. Davin Lim since I saw his before and after videos on his YouTube (and Australia isn't far from my country). Can he treat ice picks scarring?

So this is my scarring, you can see the area in white is where I applied the azelaic cream.

And as you can see that the area where I applied the azelaic turned to be 'lighter' you can see that the area where I didn't apply the azelaic still remains the same (it's still natural, like it doesn't turn to be 'lighter' like the marks where I applied the azelaic)
