Children with FAS may also have certain facial characteristics, like small palpebral fissures, which means reduced distance between the two sides of an eye, smooth, or flat philtrum, and a thin vermillion border, which is the border of the lip.

FAS患儿有一定的面部特征，如眼裂短小，即一只眼睛两侧间的距离变短；人中平滑；以及较细的唇红缘（即嘴唇的边界）。
