Adult Acne

My sister and her friend were at home last night. They were having a private slumber party for the two of them. LOL! When I went to see them to ask what they would want for a midnight snack, they told me to get them whatever available in the fridge. Then they asked if they can borrow my laptop because they wanted to search for adult acne treatments. They both have pimples on their faces. I told them to see a dermatologist but they are hesitant because they have friends who had spent so much already and yet their pimples on their faces remained. Oh well... I hope they can find solutions.
