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.

it could be better when the trainer was talking about issues or some type of disease you could show visually, the photo or the video.

It is a nice entry level course for beginners. Great for someone who has No Idea on the question. I did find some issues (content, technical)with some assignments, some repetitions but overall it was okay.

I enjoyed the content in this course, but the discussion prompts seemed faulty. I especially liked the AI discussion near the end of the course.

Dull so very very dull, inane marking system with mono tonal presenters, where's AI when you need it.
