These faces are of the same person
In the Illusion of Sex optical illusion from Richard Russell at Harvard, two faces are shown. Both are photographs of the same asexual or genderless face One face was altered by increasing the contrast, and the other face was altered by decreasing the contrast.
The face with more contrast is seen as female, and the face with less contrast is seen as male.
A face with makeup around the eyes and on the lips increases the face's contrast, and appears more feminine.
