Proper skin care essentially comes down to layering your products so that active ingredients penetrate and effect the skin as intended. The 500 dalton level rule, as it's known, is a tool of measurement used by skincare experts to determine how deeply a product will penetrate the skin.
The lower an ingredients dalton number, the more easily it will penetrate the skin. When an ingredient approaches the 500 level, it tends to sit on top of the skin without help from an exfoliant or penetrative product.

The Rule of Thumb:
You should apply your products from "thinnest" to "thickest" for more effective absorption into the skin.
Think of it like this: skin is porous – meaning there are tiny holes that allow air and liquid to pass through. If you apply a thick cream before a thin serum, that thinner substance will sit on top of the cream without actually penetrating the skin.
