This was a very informative course and I learned a lot about a subject I'm very passionate about. The only reason I gave it four stars instead of five is that the grading technology was a bit wonky (i.e. instructions said to choose one topic, but it only gave you a 66% grade if you didn't select both topics). Luckily, you can retry as many times as needed.

This course surely provides comprehensive introduction to the science behind cosmetic and skincare. Not only gained knowledge in theory, this course also rises awareness about the importance of nurturing and protecting our skin.
