The change of aesthetic era is a complex social phenomenon, which is affected by various factors such as historical background, cultural environment, scientific and technological progress, etc.

Historically, aesthetic concepts have experienced a transformation from unity to pluralism. For example, during the French royal period in the 17th and 18th centuries, fashion began to take shape, and the concept of taste as status was gradually established. Entering the Internet era, the aesthetic concepts of Europe, America, Japan and South Korea began to influence China, and the definition of beauty began to develop in a diversified direction.

However, with the development of technology, aesthetic trends are also changing. For example, the development of medical beauty technology allows many people to obtain almost the same celebrity face through plastic surgery, which to a certain extent has led to the convergence of aesthetics.

In postmodern aesthetics, beauty is no longer concentrated in one form as in the past, but presents a multi-dimensional three-dimensional appearance. This change makes people pay more attention to the promotion of personality and the protection of recognition in the process of pursuing beauty.

In general, the change of the aesthetic era is a dynamic process, which is affected by both the external environment and changes in individual inner needs. In this process, we should keep an open mind and respect diverse aesthetic concepts, while also paying attention to protecting and promoting the beauty of our own personality.
