For those of you who have received acne scar treatment, when did you start noticing the effects?

In the past, the mere appearance of new acne breakouts was the biggest source of stress, but now that my breakouts have decreased significantly, the remaining scars are actually catching my eye more. When I usually look in the mirror, I just think my skin texture is a bit rough, but under bright lighting or when light comes in from the side, the bumpy areas are more visible than I expected, so it has started to bother me. When taking photos, my face looks fine from the front, but if I turn slightly to the side, the unevenness seems to appear more pronounced due to the shadows.

So, this time, I'm thinking of properly looking into acne scar treatment. What I'm most curious about is how long it takes to see visible results. I don't think my skin will become smooth immediately after just one treatment; I suspect that changes will appear gradually over time as my skin recovers.

Honestly, I'm not expecting the scars to disappear completely, haha. I think I'll be satisfied if the unevenness is less visible when I wear makeup and if it looks a bit more even up close. In particular, I'd like the bumpy areas to be less noticeable when I apply a thin layer of foundation.

When I start acne scar treatment, do you assess the depth and shape of the scars during the initial consultation and explain what I can realistically expect? Rather than having unrealistic expectations and then being disappointed, I would like to start knowing the possible range from the beginning.

I am also curious how many sessions are needed to assess the effects. Is it possible to see gradual differences starting from the second and third sessions, based solely on the skin's reaction during the first?

For those of you who have received acne scar treatment, did you notice the changes more clearly when comparing photos than in the mirror? I am also planning to take photos in the same place under the same lighting before I start, and I’m curious if that will be helpful haha. Please share your experiences on when you actually felt a difference compared to before~~
