"Pilling" often occurs due to many different reasons, for example: - Amount of the product being applied - Consistencies of the products being used in conjunction - The total number of products being applied, etc. Your skin can only absorb a certain amount of product. Any excess will be left on top of the skin so that when the next product is being applied, it rubs off. Use 1-3 drops of each product. Use a "patting" application method, as opposed to "rubbing." Move onto the next. Please note: Water formulations should be applied before oil formulations. Use a maximum of three serum formulations in a single regimen.
