What are fungal acne and what are its symptoms? Fungal acne can sound quite scary and with so many connotations attached to it, in reality it can be among the hardest to treat, and not so much due to its severity, but rather because it’s difficult to diagnose, and can get many times misdiagnosed. Most of us have had some experience with fungal acne, so we know that it’s not as serious as some people think. That being said, if you’re still unsure whether you have a fungal acne or not, then you should definitely take it to your doctor for diagnosis, as not all cases are treated the same. And for those who do have it, there are several different treatment options that can help in dealing with the condition.
