Wondering what “skin layering” is? It's a new term for a concept you're likely already familiar with and using daily: That of using skincare products in a specific order for maximum benefits. By using skincare products in the right order, you are layering formulas in a way that boosts each product’s effectiveness. The general rule of thumb for skincare layering is to go from watery formulas to thicker formulas. Wait around 30 seconds before applying the next formula, as that allows a deeper absorption into the skin before placing another skincare product on top.
