Attribute.IsDefined always returns false

I am trying to check if a variable has a TextArea attribute, but even if it does it still returns false.

What am I doing wrong here?

public class Product
{
    [SerializeField] string ID;
    [SerializeField] string Name;
    [TextArea(4, 8)]
    [SerializeField] string Description;
    [SerializeField] double Price;
}

Product product;

public void GetProperties()
{
    PropertyInfo[] properties = product.GetType().GetProperties();
    foreach (PropertyInfo property in properties)
    {
        Debug.Log(Attribute.IsDefined(property, typeof(TextAreaAttribute)));
    }
}
