After having conjunctivitis, how long should i wait before putting on makeup?

At least one week: You should wait until the virus runs it course, this is usually 1 week. I also suggest that you may want to throw away your old eye makeup and start with a new supply when the conjunctivitis is resolved.

Not too long: When treatment is started, it can take 1-2 weeks or longer to resolve the infection. A rule of thumb is that you can re-start make-up once you have stopped the medicine. But be aware that you may feel or look better before the condition has disappeared, so it is best to ask your doctor when you can start using cosmetics.
