Research suggests that the perception of attractiveness in faces is influenced by various factors, including symmetry, averageness, and specific facial features. Some features commonly associated with attractiveness include:

1. Symmetry: Symmetrical faces are generally perceived as more attractive because symmetry is often viewed as a sign of genetic fitness.

2. Proportion: Faces with well-balanced proportions, such as a harmonious relationship between features like eyes, nose, and lips, are often considered attractive.

3. Clear skin: Smooth and clear skin is a desirable trait that enhances facial attractiveness.

4. Eyes: The eyes are often considered a focal point of attraction, with features like large, expressive eyes and long eyelashes being perceived as attractive.

5. Lips: Full, symmetrical lips are often associated with attractiveness.

6. Jawline: A defined jawline is typically perceived as attractive, especially in males.

7. Facial expressions: Positive facial expressions, such as smiling, are usually considered more attractive than neutral or negative expressions.

It’s important to note that perceptions of attractiveness can vary among individuals and cultures, and personal preferences play a significant role in what one finds attractive in a face.
