Hi, why are most moisturizers and serums etc are mostly white or light colored even though they contained lots of ingredients that should tint the product? Ingredients such as CoQ10, grape seed extract, lycopene, green tea, blueberries etc., if I mix them into the moisturizer at home it would turn into mud. Does the extracting/purifying process in the lab removes the colors? I have not seen any dark products, even those that claim to contain a high level of the actives. Thanks so much!
