COLOR VARIATION
- How can I tell if my Retinol+ Emulsion is chemically damaged?
- I have read that blue dye is an irritant, yet there is a blue dye in Hydra-Cool Serum.
- What are the small floating particles or color variations from bottle to bottle that I see in my bottle of GeneXC Serum?
- Why is the color different from the last time I ordered NeckPerfect Complex?
