@BloomingOwlPlease let me know what specifically you consider scars. If you mean the red PIE then no those are not scars but wounding post acne. The best treatment for this is a vascular laser. Otherwise it can take up to a year to heal naturally. Try things like castor oil and comfrey as it stimulates healing first. Also light peels would be effective for your shallow scarring, you could start with a glycolic peel and move to tca peels if you need more done. You can use a dermastamp at home as well if you wish just on the scars if you have light pitting.
Retin-a or tretinorin / differin is helpful nightly for slight scarring as well.
Please do not be broken out for any of these treatments as it could spread bacteria ( I see some zits).
I do not see fat loss or deep pits. Just mainly PIE.
