## Executive Summary
Why layering lightweight molecular humectants and giving each step three minutes to settle outperforms heavy occlusive moisturizers.

        Professional artists widely agree that skin prep accounts for the majority of a base's longevity. When working in high relative humidity, traditional heavy moisturizers containing mineral oils or heavy shea butter create a slippery film that prevents foundation from adhering.



        
## The Rule of Molecular Density


        Effective prep in tropical climates relies on low-molecular-weight humectants like multi-weight hyaluronic acid, beta-glucan, and glycerin. These ingredients draw hydration into epidermal cells without leaving surface residue.


        Equally critical is the wait-time protocol: allowing sixty to ninety seconds between each skincare step permits water content to evaporate and active ingredients to bind, preventing the common issue of foundation pilling.
