Well, it’s all about your genetically inherited bone structure but for some reason, everyone’s crazy about having a strong jawline. It means that your bones are quite distinguished and visible below the ear. A famous example of that is Angelina Jolie. The opposite – a weak jawline is also quite natural and most people find it unattractive. It’s usually poorly developed and indented. Some men do jaw muscle exercises in order to improve their jawline. This may work if you do it regularly but your bone structure will still stay the same and you won’t get rid of it completely.
