Pleas EXPLAIN

So i literally had clear skin a month ago, and this past week my forehead has broken out into this?? I tried out a new toner last month but didnt like it, so I went back to my old one and now im breaking out😬🥺

I went under an extreme amount of stress in march, could that be it as well?

What type of acne is this? Im also on the implant, but ive had that since august.
