While your individual routine may vary due to skin type, skin concern, time of the year, and hormonal fluctuations, the basics of layering stay the same. You layer or apply products by format first then by water solubility and thickness. The below is a guideline on how to layer products, referencing Prequel products, but is not necessarily a proposed routine. Prequel products were created as stand alone products that can be seamlessly introduced to your skincare routine. Not every step or every Prequel product may be appropriate for your skin. A routine composed of various product combinations is very personal and at Prequel we hope to offer you the tools to customize your skincare needs.
