Laurelle Renwick-Smith, 31, realised black skincare products were security tagged next to what appeared to be untagged - more expensive skincare products - for white skin.
"I was walking down the aisle and noticed that there were BB creams for black and white women, " said Laurelle, a response officer for Haringey Council.
"Only the boxes with black models on them were in a security box."
Laurelle was shocked to see the products in a security box at the Tesco store in Rainham, Essex, and initially walked past.
But she was so shocked she went back to confirm, and film, what she saw.
Laurelle added: "It didn’t sit right with me so I went back to check if what I saw was really what I saw and, to my surprise and disappointment, it was.
"I’ve never seen this sort of thing before, only on social media not on my doorstep."
The video garnered nearly 500,000 views and 42,000 likes in a day with comments claiming the store is "racist", while others claimed the decision was "data-driven".
