In my case, Soolantra removed/reduced like 90% of the problem, even after stopping with it for some time. Then I used Sudocrem for like 1 week, after which I'm 100% clean, although I'm not fully sure if Sudocrem is the cause, because it's hard to belief. Now I'm only using skin hydratation because I belief it's important for keeping the skin healthy and protected.
I hydrate my skin using Cetaphil Moisturising Cream, which also is the base/carrier ingredient of Soolantra (but not the active ingredient, that's ivermectine). I'm not using Soolantra neither Sudocrem anymore.
Soolantra is easy to use (unless you have side effects). Sudocrem is practically difficult to use, the way I used it. It can clog pores, puts a white layer on the face, and is difficult to fash off completely (it doesn't dissolve in water). I used a tick layer of Sudocrem, although using less may also work.
