My mom keeps on saying that my skin is horrible?

I have mild acne and I recently broke out due to stress from exams, and my mom keeps on saying that my skin is disgusting and horrible and its from me wearing makeup. I only wear tinted moisturizer and its NOT whats causing the acne. I've been wearing the same kind for a long time and my skin was acne-free while I was using it and I wash it off EVERY single night. Is my mom wrong to tell me this?
