Digital reading device with cosmetic function

A digital reading device, especially a digital reading device with a cosmetic function.

With the development of Internet technology, the importance of electronic message dissemination is increasing. With the popularity of the Internet, it is possible to obtain a large number of instant messages at the same time, which has led to the rise of portable e-readers. Usually referred to as an electronic reading device (or e-book), it generally includes a display device for displaying a message and an input device for interacting with the user, wherein a liquid crystal screen is used in large quantities.

On the other hand, with the increase in the degree of social civilization, people pay more attention to the appearance. The skin is covered on the human body surface, and in addition to protecting the human body, it affects the perception of others to a considerable extent. It also drives the prevalence of skin beauty. Traditional skin beauty is the direct application of chemicals to the skin to achieve a cosmetic effect through the chemical interaction between the chemical and the skin. However, such a method of using a chemical agent for skin cosmetic is easily accompanied by side effects, and even if a natural product is used, it is limited to the time of use. There are restrictions on the nature of the paragraphs, locations, and inconveniences. Recently, light beauty equipment has prospered.
