Hi, I am a 15 yr old girl, and I have sensitive dry skin with acne on my chin and around my lips as well as a bit of my cheeks next to my nose. My acne has only been getting worse as I age, and once I get pimple it never seems to go away, and just leaves a red/purple mark. Are there any specific products/routines I should do? How to do I deal with dry skin with acne? Also, do you think my acne is hormonal, and would diet play into it?
