Sunday Riley products often get rave reviews and reach cult status. Good Genes, the brand's iconic exfoliating serum racks up hundreds of 5-star ratings on Amazon and has a loyal following. However, there are two different versions and it's important to know the difference. There's the original Sunday Riley Good Genes All-in-One Lactic Acid Treatment, which is the brand’s US iteration of the Good Genes serum. This skin-brightening treatment has legions of fans stateside, including the likes of Oprah, Drew Barrymore and Helen Mirren no less. However, there's also the Sunday Riley Good Genes Glycolic Acid Treatment - the UK version, which was tweaked by the brand a few years back to adhere to the EU regulations around product formulation. You can only buy the glycolic version in the UK. If you see the lactic acid treatment for sale, I urge you to be careful as it may not be properly advertised.
The UK's glycolic acid serum promises all the same skin-brightening exfoliating benefits, but with an ingredients list that sticks to the EU rules. But is it any good? Ahead, I share my honest review of the cult serum and break down the differences between the UK and the US formulations.
