In which profile does the chin and forehead align with a sunken nose?

The concave profile is characterized by a distinctive feature where the forehead and chin are in alignment, and the nose appears sunken or concave in shape. This creates a gentle inward curve, distinguishing this profile from others.

In a concave profile, the nose is typically less prominent, giving it a receding appearance compared to the other features of the face. The alignment of the chin and forehead creates a harmonious balance, making this profile unique. This structural alignment results in a silhouette that emphasizes the inward curve of the nose while maintaining proportionate features.

Understanding these characteristics is important in the study of design principles, particularly in beauty and aesthetics, as it allows for a deeper appreciation of facial structures and how they influence overall appearance.
