I am 17 years old and have never struggled with acne before. Recently, I have been experiencing huge cystic pimples mainly on my forehead but also my chin and cheeks. As soon as the pimple clears up, it comes back within a few weeks. I have not changed my skin products or diet so I’m not sure what could be causing this or how to fix it. I’ve also been on birth control pills since the age of 14, haven’t changed those either.
