I definitely saw great improvements with the regimen! But I haven't been consistently clear with it unfortunately. I can't manage to use it in the mornings so it's just the full amount at night - and that really effects how well it works. So it's up and down with my skin - some really good days/weeks and others not so great where I do breakout a fair bit. Even when I am breaking out (like at the moment actually) it's way better than before so I'm happy to keep going with the regimen for a while longer.
I have looked into other treatments but I couldn't handle going through a withdrawal breakout from stopping BP or handle an initial breakout from starting something new right now. So I can understand what you mean with being worried about having meds changed. I think that's the only downside of having much better or clear skin for any amount of time after struggling to get there for so long, - you do become 'scared' in a way of your skin going backward. That's my experience / worry anyway...
Hopefully your skin stays under control now though!!
I'm glad you've been getting some improvements on the regimen. I can understand your worries about withdrawing from bp because when I did that after being on the regimen a couple of years my skin completely erupted! Just a thought but you could try something like Epiduo (I'm a bit biased here because it's by far the best topical I've ever used) that contains bp plus a topical retinoid as well. That way you'd be adding something more in but not withdrawing from the bp in the process. Adapalene is the mildest topical retinoid so if you're relatively clear already I wouldn't imagine you'd get much of an initial breakout. Just a thought. After my breakouts on Sertraline and Mirtazapine I'm definitely worried about the psych changing my meds around but I guess I'll just have to wait and see what they suggest. I don't mind them changing the doses of the ones I'm already on because I've already deemed them skin safe so I hope they just decide to do that rather than adding anything new. Anyway, good to hear from you and I'm glad your skin is at least better than it was before.
