Makeup contributes greatly to improving the quality of our daily lives.
Recently, the Korean cosmetics industry has grown so much that the term K-beauty has become common.
Going forward, Korea's cosmetics industry will continue to evolve through convergence with beauty, chemistry, life sciences, medicine, engineering, and AI.
Makeup reflects new cultural trends that emerge with the times.
By comparing the magical makeup of ancient times, the ascetic makeup of the Middle Ages, and the extravagant makeup of the Renaissance, we can understand how makeup has changed according to the flow of cultural trends of the times.
This textbook also covers the history of cosmetics, allowing students interested in cosmetology to examine the direction of change in cosmetics based on an understanding of cultural change.
Cosmetics are finished products made by mixing various raw materials, and the functions required for the product must be maintained from the time of production until the consumer uses it.
Amidst the flood of information about the functions and ingredients of cosmetics, choosing the right one for you can be quite a challenge. To do this, it is necessary to properly understand the ingredients, formulation, amount, and purpose of use of the cosmetics.
This textbook attempts to interpret the raw materials, ingredients, formulations, and functions required for cosmetics from a chemical perspective.
Additionally, the topic of cosmetic waste, including cosmetic raw materials and containers, was covered to raise environmental awareness in terms of human sustainability.
We have tried to create a good textbook, but there may be some shortcomings.
We ask for the readers' understanding on this point. Even if you have not majored in chemistry, you should not worry too much as the content is written in a way that you can fully understand it if you read the textbook carefully.
Please note that any future revisions or supplements will be posted on the Free Academy website's data room (www.freeaca.com).
