When Does Nose Development Begin?
The development of the nose begins early in the first trimester of pregnancy. At around four weeks, the nasal pits, which will eventually form the nostrils, start to develop on the surface of the face. Over the next few weeks, the nasal pits deepen and move closer together, eventually fusing to form a single nasal cavity.

By the end of the first trimester, the basic structure of the nose is in place. However, it’s not until the second trimester that the nose really starts to take shape. At around 14 weeks, the nostrils become more prominent, and the nasal cartilage begins to form. By week 20, the nose is fully formed, and all the major components are in place.
What Can Affect Nose Development?
While the development of the nose is largely predetermined by genetics, there are some factors that can affect how the nose develops in the womb. These include:
- Smoking: Smoking during pregnancy can lead to low birth weight and can affect the development of the nose and other facial features.
- Alcohol: Drinking alcohol during pregnancy can cause fetal alcohol syndrome, which can cause a range of physical and mental disabilities, including facial abnormalities.
- Vitamin deficiencies: A lack of certain vitamins, such as vitamin A, can affect the development of the nose and other facial features.
How Can You Ensure Your Baby Has a Healthy Nose?
While some aspects of nose development are beyond our control, there are some things you can do to ensure your baby has a healthy nose. These include:
- Eating a healthy diet: A diet rich in vitamins and minerals can help ensure your baby develops properly.
- Avoiding smoking and alcohol: As mentioned earlier, smoking and alcohol can have negative effects on nose development, so it’s best to avoid them altogether.
- Getting regular prenatal care: Regular checkups with your doctor can help ensure any potential issues with nose development are caught early and addressed.
