I had a mole removed yesterday when can I wear make up as I'm going back to work tomorrow?

I suggest speaking to your physician, typically make up is started after the scabs have come off.  Best, Dr. Emer.

If it was a Laser removal procedure, I would recommend you to avoid make-up for at least 48 hours. However, I would also strongly recommend you to give a quick call to your doctor to confirm this. At this point of time, he/she is the best person to advice you depending on the treated area type of procedure followed. 

As long as the site is clean and free of crusts or goop, you can wear makeup. I usually recommend about 48 hours after a removal, but it really depends on the size that was removed and the way it was done. You can always call the doctor's office that treated you - they'd be the best ones to let you know how to take care of it since they know exactly what was done. "This answer has been solicited without seeing this patient and cannot
