Why do some people have a strong jawline while others do not?
Quick Answer
Jawline shape is influenced by bone structure, muscle size, body fat, and genetics. The angle of the jaw and the chin’s shape play a major role in how defined it appears.
The Full Story
A person’s jawline depends on the underlying bones of the mandible and chin, plus the soft tissue above them. Genetic inheritance affects jaw size, facial proportions, and the angle at which the lower jaw meets the neck. A lower amount of facial fat can make the jawline look more pronounced, while weight gain may soften its appearance. Chewing muscles can also change in size with use, though bone structure remains the main factor. Because facial growth continues through adolescence, jawline appearance often changes as people mature.
