That is what the vendor for Beauty BioScience said on HSN today. She said it is a gold color and if your retinol product is not yellow or yellowish, it doesn't have enough retinol. I'm thinking it is true because the Isomers Retiniacin and the Tretinoin cream I used to have did have a yellowish color.

@EllenKay Your's was an Rx, correct? If so, that's is why. Rx only items tend to be and I think it's due to something they add to it. OTC (non Rx) should be a shade of yellow.
