Greetings from sweden!
I've been dermarolling for about half a year, and seen some improvement so far but I'm far from done. I'm thinking of trying single-needling since some of my scars are quite deep but I can't seem to find any good guide on how exactly one should perform single-needling.
I am therefore looking for an in-depth sort of guide on single-needling acne scars, mine specifically are a mix of rolling and boxcar scars.
Regarding the aftercare - I have just been using some strong vitamin A cream and Copper Peptides after rolling with a 1.5mm Dermaroller. I am unsure if this has negatively affected my results, I chose to not purchase the Indolfan cream you recommended due to still being prone to acne. I might however reconsider using it if you reckon it could increase my dermarolling results and not greatly increase any chance of new acne.
I am also dermarolling with a 0.5 roller and using a quite strong mix of vitamin C, which I have created myself using the vitamin C powder from your website, and after applying the vitamin C several times I have either put on the vitamin A cream or a new cream I recently purchased called Hyaluron-Filler. I am just testing it out to see if it helps anything at all on acne scars - any input on whether Hyarulon-Filler is good or not would also be greatly appreciated.
P.S Sorry if my grammar is a bit off, I haven't studied english for a whole year
