Acne and veganism

I will keep try to keep this description short and would just like to emphasize that I am nearly a vegan after being vegetarian for about a year and my acne is about as bad as its ever been. I don't have it as bad as many other people, but it still causes a lot of consciousness. So my question to any vegan that had/has acne is: How did your acne react to veganism (completely clear it/helped a little but other things helped more/nothing happened)? Also, if you remember the period of time in which any change (small or large) occured, that would be very helpful to know.I just want to be aware of as many experience as possible and appreciate any comments :)

TL;DR - I want to hear from anyone in this community who had acne and how veganism changed/did not change their skin.
