What is the best treatment for acne scars?

I've tried applying various scar removal creams and cosmetics that help with scar removal...

The scar isn't disappearing dramatically.

I thought it would naturally disappear as I got older, but that's not the case.

I never thought I would be so stressed out by the scars left from the acne I picked at when I was young.

In particular, the sunken scar on my cheek couldn't be covered even with makeup.

So, I really want to know what procedures help remove acne scars!

Some people recommend various treatments like Fraxel, Juvelook, etc., but

What are some treatments that are cost-effective and effective?

I'm so envious of people with really clear skin.

Or should I try applying Noscana Gel again... haha
