A fairly thorough course on quality control and regulation. Would have given 5 stars if more feedback was given under wrong answers, especially written answers.

Many of the tests have a fill in the blank spot, but are worded for multiple choice.

very repetitive and too puffed up

Informative and fun, a must for anyone looking to get a deeper dive into cosmetics and skincare - for science!

This was an amazing experience for me and I'm soo grateful to OLAY for this great opportunity they offer.

The Quality Control and Regulatory in Cosmetic Science was very informative and meets the objectives.

it was an amazing experience

Great for beginners

Good course

A very interesting and detailed overview over the basic concepts of the cosmetic products development. From raw materials, composition to quality and regulatory affaires.

the 1st 2 courses were amazing but the last 2 were extremely repetitive. useful but vv repetitive

it was a very informative course, but the tests were extremely buggy, sometimes giving away the answer or having answers be so specific for the type answers, it was almost impossible to get those questions correct

where is my hard earned certificate i already got the frame
