Are there any people with experience regarding acne scar treatments?

I've had severe acne since my school days, so I used to pop them frequently, leaving me with a lot of scars.

I'm curious about acne scar treatments. I've never been to a dermatologist before, so I'm a bit scared.

I heard that this isn't something that can be done in the short term and requires a long-term perspective. For those who have received acne scar treatment, I'm curious about the cost and the effectiveness.

Also, I'm wondering how often I should get the treatment... Since acne scar treatments are something you have to keep getting once you start, if I end up quitting for one reason or another, it just feels like I'm wasting money. I feel like I need to get my act together, but I'm really struggling with this decision.

Since skin regenerative capacity declines with age, it would be beneficial to receive treatment early. If anyone can share details about the advantages and features, please leave a comment.
