Pimples, Oh Dear Pimples

            "Pimples, please stay away from me. Please, I beg you. Don't keep coming back." This is what I always hear from my sister who has pimples sprouting all over her face. She didn't have that much pimples when she was younger. Some people say, it's acne. Some would also say it's allergy. But whatever it is, it's been bothering my sister. She thinks she's in dire need of the fastest and most effective product to remove pimples. She has tried almost everything sold in the market. Can you guys help me solve my sister's problem? Please? Thanks in advance. :)
