Re: Advise please
Mehroze the same thing happened to me when I came back from India and i thought I would never look the same again. The key is plenty of rest/sleep and water. Try to avoid makeup as much as possible till the 15th. Exfoliating might actually aggravate your pimples even more and create further problems for you. Use a gentle facial cleanser (such as DOVE) and light moisturizer. Nothing too harsh.
P.S. Load up on that H2O!
