Is it normal that everyone has two different faces when taking photos from side or looking at 3 mirrors?

Everything in nature, including the sides of the human body, are not symmetric. In fact, if you created a composite image of your face, composed of one side, and its mirror image, the composite image would not even look like you. 

We all have facial asymmetry that ranges from mild to severe. This is not at all unusual. If you have concerns about this, you might consider facial treatments to camouflage and reduce the apparent asymmetry. Seek a consultation for specific advice about treatment options. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

No one is symmetric!  The two sides will always look different even if you have surgery to improve symmetry.

Dear Alexis93,

The question you ask is a very good one. The vast majority
of people (>90%) have noticeable differences between the left and right side of
their face. The majority of these differences are related to facial skeletal
growth as we age, but differences are also noted in skin, facial fat volume, muscle tone, hair distribution and even eye
color. We commonly do not see these differences as we often glance over such
asymmetries. I hope this helps you in the answer you are looking for.

Be healthy and be well,

 Everyone has some degree of facial asymmetry  throughout the entire face, for which surgeons have to deal with when performing facial cosmetic surgery. This includes uneven eyebrows, uneven upper lids, bony orbits,  one cheekbone higher than the other and the mandible  is more prominent on one side or the other. The reason for this is that in the embryonic development, there is a left-side and a right-side of the face that comes together and is never perfectly symmetrical.

Without pictures of an in person physical exam it is very difficult to make an assessment of your concern. I suggest that you post pictures of yourself in different angles (front, each side and each 3/4 views).Every person in this planed has differences from one side of the face to the other. There is no symmetric face out there. Only when the difference is very dramatic that then something might have to be done to improve it.Hoep this helps,Dr. Gus Diaz
