(CNN / HLN) -- If you're considering a nose job -- you shouldn't use a selfie to help you make the final decision.
That's because selfies apparently lie when it comes to nose size.
According to a new study in the journal Jama Facial Plastic Surgery, selfies can make the nose appear roughly 30% larger than it actually is.
Researchers say the increase in perceived size occurs when the selfie is taken at a distance of about 12 inches from the face.
That's because the camera is proportionally much closer to your nose than to the rest of your face.
When the picture is taken from a distance of five feet, the distortion isn't nearly as significant.
