Well I can understand not wanting to go off the lithium since it has helped you so much and it makes sense why the minocycline was discontinued because both medications hit the liver hard. So with that being said you are right that oral medications for acne may not be appropriate for you because how sensitive your liver is on the lithium. A good topical prescription medication for facial and body acne is the sodium sulfacetamide wash. I have heard many positive reviews for it, so it may be worth looking into and this can be prescribed by a GP, not a dermatologist. Or if you want to go a cheaper over the counter route, a sulfur bar soap is good too. I use the Sal-3 soap and it works well for me, here is the link
Thanks for the input! I'm somewhat hesitant to use any kind of prescription cleanser because other parts of my face are quite dry, and non-oil-based cleansers (as I have recently learned) strip the skin of its natural oils, making it an even better breeding ground for bacteria. I think I might try the soap you recommended, but as a treatment wash instead of my regular cleanser. I want to make sure not to dry out the rest of my face where I'm not breaking out. I may even switch my current regular cleanser (I fear it may be irritating the skin further).
I just did some research, though, and I discovered that acne is sometimes caused by stress, hormones, or irritation from certain foods. I think I might try to cut out dairy for a little while and see if that makes a difference. I'm afraid of damaging my skin further with the use of a harsh wash. I also go to the doctor tomorrow, and she may just have a nontraditional idea about how to treat the acne.
Once again, thanks so much for your comment! I think using the soap you mentioned as a treatment could be really beneficial!
