Hello, I had pimples due to dust allergies and so my doc prescribed Retino-A 0.50% cream and Tretiva-30 tablets. Retino to apply twice a day and tablets to take before sleeping at night. Also he said by taking the tablets, it will dry up my lips also because of the cream my cheeks have become red n its itching even if i touch my skin... I want to ask is should i continue it ? As he has called me after 20 days n only 10 days have passed.
