Is hormonal acne actually a thing??

So I'm almost 25 and I ONLY break out around my mouth/chin. My skin is clear everywhere else, but around my mouth/chin it's pretty bad and I have tried literally everything (prescriptions, natural methods, etc. to get it to go away and it wont!) I went to the dermatologist and told her I think its hormonal acne and she told me that "hormonal acne doesn't really exist. Acne is just acne." However, I only break out around my mouth and chin so it makes me wonder if it really is hormonal and there's something deeper going on... what do you think? Help!
