Acne, like most diseases, doesn't have a root cause.
FactorsFactor ix complex which contribute are oil, bacteria, genetics, and luck. Acne at 25 is quite
commonCommon cold. Even so, it eventually goes away. Treating it usually involves both oral and topical antibiotics, as well as derivatives of Vitamin A. With patience and proper follow-through (and avoidance of any picking or squeezing), you should do fine. All medications, by the way, take 2-3 months to take effect in acne. Hence the request for patience.
Best.
