【Cosmetics Ingredient Certification Level 2 Exam Prep】Original Problem Set｜Practice Problems for Efficiently Learning Important Points For those studying to pass the Cosmetics Ingredient Certification Level 2 exam. "I've read the textbook, but I get confused when it comes to the questions," or "I want to solve more practice problems at the actual exam level." This original problem set was created for those people. This problem set includes practice problems based on the scope of the Cosmetics Ingredient Certification Level 2 exam, focusing on ingredient knowledge and important points that are likely to be tested. Even if you understand the content of the textbook, the actual exam requires the ability to accurately judge "the differences between similar ingredients" and "the functions of ingredients." This problem set is designed with these points in mind, where it's easy to make mistakes on the exam. The content covers the following themes in a balanced manner: ・Moisturizing ingredients (hyaluronic acid, ceramide, collagen, etc.) ・Whitening ingredients (vitamin C derivatives, arbutin, etc.) ・Anti-aging ingredients (retinol, niacinamide, etc.) ・Cleansing ingredients/surfactants ・UV protection ingredients ・Plant-derived ingredients ・Preservatives and stabilizing ingredients ・Functions and characteristics on the skin The question format is multiple-choice, designed to mimic the actual exam, so you can use it not only to check your knowledge but also to train yourself to get used to the feeling of the real exam. By solving the problems repeatedly, you will naturally be able to organize the characteristics and roles of important ingredients. In addition, knowledge of cosmetic ingredients is useful not only for certification exams but also for deepening your understanding of skincare and choosing cosmetics. It is also recommended for beauty consultants, estheticians, those involved in cosmetics sales, and those who love beauty and want to learn about ingredients. It is useful not only for exam preparation but also for those who want to check their knowledge in a short amount of time or increase their practice volume.
