英文小作文：

Hypodermic fat is a type of fat that is injected under the skin to enhance the appearance of the body. It is often used to fill in areas of skin that are lacking in volume or definition, such as cheeks, lips, and other areas of the face. The procedure is usually performed by a trained professional using a small needle to inject the fat into the desired area. The result is a natural-looking enhancement that lasts for several months or longer, depending on the amount of fat injected and the body"s natural process of fat breakdown and absorption.

Hypodermic fat injection is a popular cosmetic procedure that can help people feel more confident about their appearance. However, it should always be performed by a trained professional to ensure that it is done safely and effectively. Before deciding to have the procedure done, it is important to consider all of the risks and benefits, as well as any possible side effects that may occur.
