For those of you who are familiar with the inner workings of the cosmetic/packaging-manufacturing world, you have definitely heard the following terms: Quality Control and Quality Assurance.  Interestingly enough, most consumers and even industry insiders are not quite clear on the difference between the two worlds.  Below is a short explanation to help you understand the definitions of both quality control and quality assurance, as well as the importance of both functions in a cosmetic/manufacturing environment.


QA is a set of activities for ensuring quality in the processes by which products are developed.

QA aims to prevent defects with a focus on the process used to make the product. It is a proactive quality process. The goal of QA is to improve development and test processes so that defects do not arise when the product is being developed.


QC is a set of activities for ensuring quality in products. The activities focus on identifying defects in the actual products produced.

QC aims to identify (and correct) defects in the finished product. Quality control, therefore, is a reactive process. The goal of QC is to identify defects after a product is developed and before it is released to the consumer.

As you can see, both processes are essential in successful product executions.  QA & QC go hand in hand in ensuring that the consumer receives a quality product by properly testing the product during development, inspecting the product for defects and correcting any issues once manufactured.

After all, Quality is never an accident! It is the direct result of a sincere and intelligent effort.

    I am a QA QC engineer and this article will help many people who have no idea what Quality Assurance or Quality Control is to understand what it actually is. I work in a packaging company and I can say that the packaging companies are now taking efforts to make sure that the quality of their packing is high. Since the competition is high, everyone wants to make the best. Because if by some case an issue arises that will be beneficial for the competitors.
