@pure.logic3: Bold Lips or Bold Eyes? 🧬 🧬 Why Some People Have Bold Lips Fuller lips are mainly influenced by genetics. Lip size depends on soft tissue volume, fat distribution, and the orbicularis oris muscle. Lips also appear “bolder” because they contain many tiny blood vessels, which gives them a naturally reddish tone. Hormones (like estrogen during puberty) can also affect lip fullness. 👀 Why Some People Have Bold Eyes Larger or more noticeable eyes are influenced by skull structure and genetics. The size of the eye opening (orbital shape), eyelid structure, and iris contrast with the sclera (white of the eye) all make eyes stand out more. Humans naturally notice eyes quickly because the brain prioritizes them for communication and emotion reading. #BiologyFacts #Genetics #ScienceTok #HumanAnatomy #DidYouKnow
