1. How do we use differin cream to reduce blackheads & whiteheads? Do we apply it on recurring acne outbreak (eg. Chin, hairlines, on the cheeks)? If I were to put a pea sized amount to my whole face(once a week), it’ll be really drying the next day so I decided to put it on acne area instead.

2. Will applying differin cream to PIH helps to lighten it as well and prevent acne? Or should I stick to the pigmentation cream given by the doctor & apply moisturiser afterwards?

Thank you!
