high levels of humidity may have influenced the evolution of broader, flatter noses in some Southeast Asian populations. A wider nasal structure can potentially help with warming and humidifying air efficiently, although nose shape is influenced by many factors, including genetics, ancestry, climate, and population history.

If you notice something unusual on your skin seek professional help. #skinhealth #healtheducation #skinconditions
