I agree with the people that said to take probiotics. Definitely do that. What helped me the most, as someone who has proven insulin resistance, was going on a low-carb diet. That made me go from 1 new zit per day to less than 1 new zit per week. I know I have insulin resistance because I took a fasting insulin test and then did the HOMA calculations. Normal fasting insulin is less than 10; mine is over 12. And carbs / sugars make me crash.
I recommend that you go in for a full hormone panel. It should tell you a lot about what's going on. Also buy some quality probiotics.
can you please tell me where i need to go/who i need to go to to take this test?
and can you please tell me the exact name or type of probiotics you are taking
I went to Direct Labs to order my tests; they have good prices and it's between you and their company so no need to see any doctors. But you'll likely be paying cash. Best thing to do is save up money for multiple tests at once because if you just do 1 test at a time you won't be gleaning as much meaning from them as if you do multiple tests together. Like some tests are related to each other and you get more information if you do them both at once instead of months apart.
Also, if you email them for a combined discount they'll most likely give you one. I do that all the time. And there are also coupon codes on the internet for like 10% off for use with Direct Labs.
Regarding probiotics, I use Garden of Life Ultimate Care, it has 34 strains and 100 billion CFUs so it's pretty powerful. I don't know if it will help with your acne but it'll help repair the damage done to your gut flora by antibiotics. You'll probably notice easier digestion too. I took it because I had a fungal infection on my arm and the antifungal creams weren't working but the probiotics cleared it right up.
