"after retin a seemingly stopped working, my doctor put me on differin. i had high hopes but it didn&#039;t work out. this gel didn&#039;t cause the dry irritation in my skin but instead caused my skin to become excessively oily which then cause blackheads to pop up all over my face, which i&#039;ve never had a problem with them, except maybe a few on my nose and in the creases of my nose. i started getting blackheads on my forehead (and i&#039;m not talking about them being barely noticeable, they were large and made noticeable bumps on my skin) on my chin, between my eyebrows - everywhere. i also started developing acne on my cheeks which i&#039;ve never had before so i stopped taking the mediation after that completely."
