    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!
