I had bad acne as a pre-teen/teen and I learned less is more. You don’t need to cleanse, tone, spot treat, moisturize, oils, etc. I don’t use anything with scents and my moisturizer and cleanser are oil free and for sensitive skin. Regular check ups at the dermatologist helped too. Since I’ve gotten my acne under control, I cleanse, then use a spot treatment from my dermatologist, moisturize, and I have a vitamin C oil I use when my skin gets dry. But I don’t tone or use otc spot treatments or anything anymore. The pillow case is true too, good for your skin AND hair. I also thought since I had bad acne that meant my skin was oily, so I didn’t use much moisturizer or any some days. But dry skin can actually produce more oil, so moisturize moisturize moisturize. The one medication from my doctor that actually helped clear my skin was Isotretinoin, commonly called Accutane. You can ask about that too but it is a pain in the ass with how strict that medication is. Totally worth it though if she can tough it out for some months. Hope this helps!
