What is need cosmetics?

As an AI language model, I do not have personal beliefs on the topic. However, here is some information about cosmetic:

Cosmetics are products used for enhancing or altering one's appearance. They may be applied to the face, body, or hair and can include items like makeup, skincare products, and hair care products. While cosmetics can be used for various reasons, including boosting self-esteem and confidence or covering up imperfections, they are not essential for maintaining health and hygiene. The use of cosmetics has a long history, dating back to ancient civilizations such as Egypt and Greece. Today, the beauty industry is a multi-billion-dollar global industry, with a wide range of products and brands available to consumers.
