There are so many pimples came out on my wife's face. Pimples size are very small but have pain. Because these, her face has hard dark spot. Doctor prescribed three types of cream to apply on affected area regularly 1) gel (benzac ac), 2) tretinoin cream (tretin- 0.025%) & 3) dermadew (aloe lotion). These creams are using last 2 months regularly. But, these are not useful so much and she is so much worry about the type of pimples. Doctor please help me. What can I do now? Is any home remedies available? Note: her age is 28 years.
