As we all know, Costco has always been known for its cheap and great products. The website is also occasionally updated with some of the biggest names in skincare.

And the prices are much better than in other places, which makes Costco a good place to stock up on skincare products.

The company's main goal is to provide the best possible service to its customers.

The company is now issuing a mass refund notice. A user reported on social media that he received an automatic refund email from Costco today, saying that the double essence he bought a few months ago was fake.

The notice reads, "Our records show that you purchased one or more bottles of Clarins Double Serum Aged Control Concentrate, product code 994432, at Costco in 2022.

"Recently, it has come to Costco's attention that some Double Serum products were not supplied directly by Clarins and that products sold during this period may have been counterfeit," Costco said it has now issued an automatic refund for the Double Essence sold in 2022, which will be refunded directly to the credit card.

The suspected fake Double Essence was sold primarily in the U.S. for $79.99 originally and $86.59 after tax. The same product is available at Sephora for $130, which is a lot cheaper by comparison.

At this time, Canadian consumers have not been notified of the refund or recall.

However, as a very trusted brand, Costco this "suspected sale of counterfeit goods" news out, the netizens were instantly unnerved.

A netizen said that he used the double extract bought by Costco after the symptoms of "allergy, dermatitis", "skin redness peeling stinging, also grow small pimples."

As early as 2020, there is more than one netizen raised the issue of "Costco buys double extract suspected fake".

The webmaster said that after comparing the double essence bought from Costco with three other bottles bought by his roommate from the British and American counter and duty-free stores, "I found that the appearance, texture, and weight of the bottles were different.

The font printing position, thickness and precision, and even the height of the bottle are significantly different."

Another user also said, "The printing on the bottle is not the same height as the one bought in the U.S. department store, ah, the cap is very loose and the printing on it is rough.

Opened a bottle and smelled the smell, not at all the smell of the product sold on the counter! Terrible! Returned!"

So it seems that we usually buy things or more careful eye, feel that the product is not right to decisively return.
