Are you wasting your creams by layering them incorrectly? You've spoken to your dermatologist, invested in the creams that best suit your skin and are slathering them on consistently, just as you were told. So, why are your pores clogged and your skin looking lackluster? It could be your routine. Creams, serums, lotions and oils have different consistencies and weigh different amounts which means putting them on incorrectly could prohibit them from sinking into the skin. The general rule is to choose no more than three at a time and layer them by weight, lightest to heaviest.
