Lip Shape and Fullness

Some people like full lips, while others prefer thin lips, and it’s not uncommon for people today to get different plastic surgeries and injections to alter the shape of their lips. Wherever you stand on the matter, did you know that your lip shape is mostly inherited from your dad’s side? The shape and fullness of a person’s lips are traits influenced by a combination of genetic factors. Lip characteristics can vary widely within families due to the complex interplay of multiple genes.

While it is true that some genetic factors related to lip shape and fullness may be inherited, these traits aren’t solely determined by a person’s paternal lineage. Both parents contribute genetic material that shapes their children’s physical features, including lips. The expression of genes can vary, leading to diversity in lip appearance even among siblings. Environmental factors, lifestyle, and personal habits can also impact lip health and appearance.
