Welcome back to this series in which we’re learning more about specific density of our ingredients and why it matters. In part one, we talked about what specific gravity (relative density or specific density) meant, then we took a look at how we might make an anhydrous facial serum using these concepts. In part two, we looked...

Welcome back to this series in which we’re learning more about specific density of our ingredients and why it matters. Yesterday, we talked about what specific gravity (relative density or specific density) meant, then we took a look at how we might make an anhydrous facial serum using these concepts. Today, let’s take a look at...
