Saccharide Isomerate
Also known as: Pentavitin (brand name), Carbohydrate Complex
What It Is
A plant-derived carbohydrate complex that forms a moisture-binding film on the skin surface. Derived from plant sugars.
What It Does
Acts as a skin-identical humectant that binds directly to skin proteins, providing long-lasting moisture retention and a "memory" of hydration.
Best For
Benefits
- Binds to skin keratin proteins for extended moisture retention
- Provides hydration throughout the day with a single application
- Non-irritating and gentle
When to Be Careful
- Often appears as a secondary humectant in formulas rather than the primary active
Brands marketing "intelligent hydration" or "skin memory" features often feature saccharide isomerate as the mechanism. It offers a differentiated story from standard HA or glycerin.
Often seen as a marketing ingredient. While the "skin memory" marketing is somewhat embellished, the underlying mechanism of keratin-binding for extended hydration is genuinely documented.
Part of serums or moisturizers. Hydration step after cleansing.
All skin types. Particularly useful in products where long-lasting hydration is the primary goal.
No concerns — well tolerated.
