Ozon and Wildberries, are there a lot of counterfeit products??

Hi! I’m an American living in Russia. I would like to be able to buy some vitamins and things on Ozon or Wildberries.

The problem is that is America, when you buy from Amazon, almost every thing is fake now and that is very dangerous.

Would you say Ozone and Wildberries are like Amazon in that way? Or are these websites more safe, and NOT selling counterfeit vitamin supplements, skincare, etc.

Im really concerned and don’t want to end up ingesting something dangerous like people in America are faced with from Amazon.
