The model’s new product, in partnership with a brand called Whitenicious, was announced on Instagram.
The Whitenicious x Blac Chyna Collection is described as an “illuminating and brightening cream” that “lightens without bleaching skin out”.
Some skin lightening products are banned in the UK.
The founder of Whitenicious is Cameroonian pop star Denecia.
There has been controversy around her brand since it launched in 2014.
In an interview with Ebony at the time, she was quoted as saying: “Will Whitenicious bleach your skin if you use it on all your skin? Yes, it will. Are we selling Whitenicous for that purpose? No, we’re not.”
The company says its cream is meant to be used for conditions like hyperpigmentation, when people have dark spots on their skin.
But that hasn’t stopped a backlash against Blac Chyna, who rose to fame stripping and modelling, before launching a make-up brand and having a child with Rob Kardashian.
Despite some people using skin-lightening products as a cosmetic procedure to change the appearance of blemishes like birth marks, they have a bad reputation the world over due to the harmful ingredients that some can contain.
The NHS says that “powerful skin-lightening creams” can be prescribed by a doctor, usually containing hydroquinone and/or corticosteroids, a steroid medication.
But products containing those ingredients which haven’t been prescribed by a medical professional are banned in the UK.
A UK man was jailed for selling toxic skin-lightening products earlier this year.
Blac Chyna’s product doesn’t contain any of those ingredients, but she’s been accused of “exploiting” Nigeria’s colourism problem.
Colourism is prejudice against people who have a darker skin tone, and/or the preferential treatment of those who are of the same race but lighter-skinned.
Many skin-lightening products are not banned in Nigeria, where 77% of women are reported to use some form of them on a regular basis according to the World Health Organisation .
Dr Harvey Olufunmilayo is a Nigerian doctor training in Britain as an NHS GP, who says he’s seen first-hand how skin-bleaching products “can be harmful to the kidneys, how they can be harmful to the liver… how they can make it difficult for wounds to heal because the skin is too thin, too fragile”.
“If their kidneys get ruined, they don’t get free healthcare like we do in the UK.
“The UN has declared Nigeria to be the poverty capital of the world, with the highest number of poor people in the world. We shouldn’t really be encouraging that kind of thing.”
