[acne] hormonal acne - estrogen dominance vs androgen excess?

i’m trying to get to the root cause of my acne and i’ve been reading a lot that acne around the jawline signifies hormonal acne. i’ve also read some sources say hormonal acne is too much estrogen relative to progesterone and other sources say it is due to an excess of androgens (ie testosterone, dhea, others?) relative to estrogen/progesterone. i would love to understand how to discern between these types of hormonal imbalances.

and if y’all are saying the only way to know is by getting tested for hormones - what tests are you asking for (which hormones, blood or saliva or urine, etc), from which type of doctor and is it even possible to get the tests covered by insurance (american) and if so how?

root cause related input only please! i don’t need to know that i can go to my derm to treat the symptoms
