It is not so different from how you recognize people. If someone has lost a lot of weight it takes a bit longer to recognize a friend but you are still able to do so. Facial recognition is advanced enough to have similar capabilities than human beings.
Interestingly enough it depends on the quality of the data used to train the facial recognition software. For the sake of an example, suppose that the algorithm was trained only with young faces. Then the software will have problem distinguishing older ones. So, for accurate facial recognition the software need to be trained with faces of all countries, genders and ages to avoid blind spots.
