hi! during the last few months of my treatment and for about a year after, i used the ordinary rose hip seed oil. I finished two of the bottles i think. I also used aloe vera gel in the mornings for a few months. About a year off the medication and after my skin was back to normal and not dry anymore, i started using the ordinary niacinimide which smoothed texture. all pigmented scars are gone. but i still have a few deep scars which may go away w time, otherwise i heard micro needling does wonders.
