Topic moved to prescription acne medications forum
Going to your doctor to ask their opinion is a good idea. But with most treatments like this it's usually advised to try them for 3 months first. So maybe give it another month and see how it goes. But of course, see your doctor if you want to discuss treatment or your progress with them.
If I'm honest, there has always been some kind of small spot breakout but I consider that clear. At the minute, I have had a few active spots but I see myself as clear at the minute. If you want to track my progress I update my forum every Sunday when possible. Before treatment, I had about 7 cysts dotted around my cheeks so it's a massive improvement. I just don't know whether it's the differin or tetracycline that's doing it for me :/
I suggest sticking with it until the end of the course, treating acne will 100% always take time and generally it gets worse before it gets better. It did for me and I'm paying for it with PIH. Don't pick your spots! Especially if you are asian like me...
