Yes, lamictal has given me acne and my dermatologist did the same "treatment" as you: soap, cream, antibiotic, etc.. None have worked.

Wish I could say more, but just letting you know that you're not alone.

Some of these meds have annoying side effects.

I've also tried special acne soap for my face during the shower and that doesn't cut it. I have to wash my face more often.

I'm 27, so I should be beyond the acne stage. Not that adult acne can't happen, but just sayin
