Oh dear Jesskaa, I know what you're going through although it didn't hit me until my early 20s (I'm 32 now). Like you most recently I was on Duac and Retin-A, and when my derm first saw me she prescribed those plus a sulfur face wash (Complexion is the brand name, but I got the generic) and an oral antibiotic twice a day for months. (I'm already on BC hormones via Nuvaring.) After three months there was significant improvement and now after a year I'm only on the sulfur face wash and Retin-A. Over the years I've tried all sorts, Differin, Tazorac, topical antibiotics (blech), but never Accutane. (The treatment can be harsh, right now a friend of mine is suffering extremely dry skin along with peeling and cracking. Ouch! Thankfully I haven't had to use it, but I would if I had to.) Retin-A will always be part of my regimen cause acne seems to come back whenever I stop using it.
I use generic/pharmacy brand of Cetaphil face wash and find that it's just as good as the regular Cetaphil. (And it does not clog pores.) It's not strong enough to remove makeup so I use it for washing my face in the morning. (Mixed with a little baking soda it makes the best exfoliant, I've experimented with tons of them but I've been loyal to this for over a decade now.) Purpose by Johnson & Johnson is the best and gentlest makeup remover to use at night. The combo of all the treatments you are using can make your skin sensitive so I'd recommend avoiding harsher cleansers (e.g., glycolic acid, etc.) unless approved by your dermatologist.
Best wishes for a lifetime of clear skin!
BTW, now that I'm in my 30s my doctor has to call the insurance co to get them to pay for my Retin-A since they want to make sure it is being used for acne and not wrinkles. I hope I have to use it forever cause it's probaby the reason why I still look like I'm in my early 20s!
