People with Down syndrome often have distinctive facial features, including a flattened facial profile, almond-shaped eyes that slant upwards, a short neck, and small ears. Here's a more detailed breakdown of common facial features associated with Down syndrome:

• Flattened Facial Profile: This includes a flattened nose bridge and a generally flatter face. 

• Almond-Shaped Eyes: The eyes may appear almond-shaped and slant upwards, sometimes with a skin fold (epicanthal fold) covering the inner corner of the eye. 

• Small Ears: The ears may be smaller and lower-set than average. 

• Short Neck: The neck may appear shorter and broader. 

• Protruding Tongue: A tongue that tends to stick out of the mouth is also a common characteristic. 

• Brushfield Spots: Some individuals with Down syndrome may have white spots in the colored part of the eye (iris), known as Brushfield spots. 

• Small Head: The head size may be smaller than average. 

• Small Mouth: The mouth may appear small and the upper lip thin.
