I. Basic Points
Self-introduction is an important method and means of promoting oneself and the image of an organization. A proper introduction can leave a deep and favorable first impression, gaining others' understanding, trust, and support. An improper introduction, however, can cause a lot of trouble and may even render your previous efforts futile.
Before a formal introduction, one should smile and first say: "Please allow me to introduce to you..." or "Let me make an introduction," "Please allow me to introduce myself," etc. Such expressions give the listener an impression of humility, politeness, civility, and elegance.
