    Not impressed

    I have been using this product for some time now and found it helped with my combination skin. I ordered 2 bottles of Niacinamide Serum, expecting to receive the usual product, but the colour was a brownish colour, where it was normally white/clear and the smell from both bottles was like old paint. I complained about this and eventually received replacements which turned out to be exactly the same. Not impressed!

    Hello Ann Marie,

    Thank you for taking the time to share your feedback on our Niacinamide Serum. We sincerely apologize for the disappointing experience you've had with the product, and regret the inconvenience caused by receiving discolored serums. We take great pride in our commitment to quality, and this is certainly not the experience we want any of our customers to have. Please do reach out to our Customer Experience Team, as we would love the opportunity to investigate this issue further, understand what may have caused the discrepancy, and find a resolution that meets your expectations 🖤
