“Generally talking, merchandise ought to be utilized from thinnest to thickest when it comes to consistency – excluding oils,” mentioned Joyce De Lemos, beauty chemist and cofounder of Dieux. The reasoning right here, in keeping with De Lemos, is that water-based formulation, that are normally the thinnest (however not all the time), ought to be utilized first to allow them to seep into your pores and skin simply. “If you’re utilizing the metaphor of bricks and mortar for the pores and skin, then you definately need these thinner, water-based merchandise to enter that watery mortar, because it have been,” defined De Lemos. “As you layer up, you wish to seal in these elements you simply utilized with thicker merchandise and lock them in.”As De Lemos famous, oils are a bit of trickier to categorise as some are tremendous skinny and light-weight, just like the so-called dry oils. However, her recommendation was to use oils proper on the finish, “virtually such as you would a high coat in your manicure.” In actual phrases, this normally means washing your face, making use of serums or essences, then following up with thicker lotions.
