But retinol breaks down in sunlight and on contact with air – turning it even more intensely yellow. So, if a retinol product is yellow, it could have lot of retinol, just not be stable, or contain added colorants / dyes.
When Vitamin C is exposed to air for prolonged periods of time, it oxidizes which in turn causes the yellow/brown color change in our usually white cream. It is a natural process that happens to Vitamin C that is not reflective of the quality of the product.
