According to the scientists, the balance of the facial ratios and proportions can increase one's perceived attractiveness. Shorter middle third ratio makes people look younger, while longer middle third ratio makes people look more mature.
If you have longer middle third and want to look younger:
Emphasizing lower lashes so it helps shift eye level lower
Avoid applying nose contour in 2 parallel lines all the way towards to nose tips
Start contouring from the nose root, mimic natural shadow of the nose tip
For nose highlight, do not apply at the entire nose
Smudge out the lip product a little at your upper lip
