What Saccharide Isomerate does

Draws water into the skin
Helps skin hold on to moisture
Gives a light, smooth feel

Saccharide Isomerate is made from sugar syrups, usually based on glucose. Manufacturers treat these syrups with enzymes that rearrange some of the sugar molecules, so the result is a blend of several simple sugars rather than one single sugar.

In formulas, it is valued as a humectant. Humectants attract water and help the skin stay soft and supple. It feels light and non-greasy, and it blends easily into water-based gels, creams and lotions. It is generally considered gentle and well tolerated.

Good for

Suits people who want extra hydration in lightweight moisturizers, serums or lotions, including those with dry skin.

Frequently asked questions

Is Saccharide Isomerate the same as sugar?

It is related to sugar, but it is not the same as table sugar. It is a blend of simple sugars, such as glucose and fructose. Its job in a formula is to hydrate, not to sweeten.

Does Saccharide Isomerate cause irritation?

It is generally considered gentle, and most people tolerate it well. As with any skincare ingredient, if your skin is very reactive, test a small area first. Stop using a product if redness, itching or stinging appears.
