I totally get where you’re coming from - it’s a super difficult spot to be in, where you’re seeing results and want to push them, but don’t want to undo any hard work.
I’d definitely recommend switching out one of your AHA products for a retinoid or retinol - you’ve got the added benefits that retinols are also a great treatment for active breakouts as well as hyper pigmentation, so at least in my mind the risk for doing this is really minimal.
I think identifying what sort of scarring you’re experiencing is an important step here too - for example, there’s ice pick scarring, which won’t really go away without getting some sort of professional involved (either with laser, or fillers). I know that’s the answer literally no-one wants to hear (I have one ice pick scar that I’m choosing to live with rather than treat because $$$), but more superficial scars have better chances. Like Shannon said, this is definitely not a quick process, so managing and setting your expectations can actually help your results - for example, don’t give up retinol if you don’t see results after one bottle.
Another thing I’d recommend introducing (which you may already be using, if so great) is just a straight up Hyaluronic Acid - there are great options that are affordable in Hylamide and The Ordinary. I’ve personally found that in conjunction with other treatments it’s going to help to boost your skin healing time, plus when you think about it - fillers are used to treat scars, fillers are more often than not Hyaluronic Acid. Again not going to see crazy instant results but it will help to get where you’re trying to go, plus it’s a relatively low risk product to add to your routine because there’s no risk of over exfoliation and very minimal risk of breaking out from HA serum.
Hope this helps!
