Beta-Glucan: Soothing & Deep Hydration
Beta-glucan is the soothing polysaccharide derived from oats: a protective veil that extends hydration and comforts sensitive skin. At NOPAL LIFE, this plant-based glucan works with the softness of prickly pear oil to envelop reactive skin.

In brief
Understanding the molecule
The structure of beta-glucan, and what distinguishes it from other moisturizers.
Among cosmetic polysaccharides, beta-glucan holds a special place. It is a long molecule formed by the assembly of glucose units. Its structure and branching vary according to its origin — a point that explains the diversity of glucans found in formulations. Oats provide chains with β-1,3 and β-1,4 linkages, while yeast and certain mushrooms yield glucans branched in β-1,3 and β-1,6. These specific, high-molecular-weight structures explain the enveloping feel of beta-glucan and its ability to form a flexible film on the skin's surface.
In cosmetics, NOPAL LIFE prioritizes a plant-based origin from cereals: oat beta-glucan, obtained by gentle extraction, offers a stable and well-tolerated molecule. These specific molecules, naturally present in oat bran, give glucan its enveloping effect and soothing profile when applied externally. It is a discreet soluble fiber, but with a real sensory role.
Beta-glucan, hyaluronic acid or glycerin?
Three moisturizers found in serums, three ways to envelop the skin. Benchmarks for choosing.
| Criterion | Beta-glucan | Hyaluronic Acid | Glycerin |
|---|---|---|---|
| Molecule Type | Oat polysaccharide (β-1,3/1,4) | Linear polysaccharide | Humectant polyol |
| Molecular Weight | High | Variable (high to low) | Low |
| Sensory experience | Enveloping, comforting veil | Fresh and light | Melting, richer at high doses |
| Benefits | Soothed appearance and supple film | Plumps the appearance | Draws water to the surface |
| Ideal for | Sensitive, reactive skin | Dehydrated, mature skin | All skin types, as a base |
| Recommended dose | 2 to 3 drops of serum | 2 to 3 drops of serum | integrated into the formula (often 3 to 5%) |
The three complement each other well in the same routine: beta-glucan for comfort, hyaluronic acid for plumping, glycerin as a fundamental humectant.
Do not confuse: skin and plate
Beta-glucan exists in two distinct worlds. This page describes only the first.
In cosmetics · the subject of this page
Applied to the skin in a serum or cream, this glucan is appreciated for its prolonged hydration, comfort, and soothing effect on sensitive skin. This is the only use described here, and it does not involve any health claims.
In nutrition · a totally distinct use
Ingested, beta-glucans are dietary fibers. Those from oats are studied in the health field, particularly by EFSA regarding blood cholesterol (LDL) and glucose. Those from yeast, baker's yeast, and certain mushrooms are the subject of specific studies on the immune system: immune cells such as macrophages, responses related to immunity and resistance to winter infections, and respiratory comfort. These immune molecules are ingested, never applied to the skin.
These studies relate to diet and the body: they concern food supplements and dietary intake, never cutaneous application. Their conclusions and studies say nothing about the cosmetic effectiveness of a skincare product: they concern ingested molecules and make no promises for the skin. On this page, beta-glucan is presented only as an active ingredient for hydration and comfort.

A carefully selected ingredient
The quality of a glucan depends on its raw material and its production. NOPAL LIFE uses ingredients with traced origins, whose purity is verified by laboratory controls: identity tests, conformity analyses, and batch-by-batch production monitoring for a stable and well-tolerated active ingredient.
Each analysis aims for the same objective: a clean, homogeneous beta-glucan that is true to what is announced on the label. It is this demand for quality and conformity, from sourcing to finished product, that guarantees ingredients that live up to the expected gentleness — the same rigor applies to all products from the house.
Stability studies confirm that these polysaccharides retain their properties over time: their sensory effects remain constant from one product batch to another, ensuring a consistent experience with each application.

Why beta-glucan at NOPAL LIFE
A molecular cousin of colloidal oatmeal, beta-glucan concentrates its soothing intelligence in serum form. At NOPAL LIFE, it calms and deeply hydrates, while prickly pear seed oil nourishes and protects. Gentleness, in a high-performance version.

Frequently asked questions about beta-glucan
What is beta-glucan?
A complex sugar (polysaccharide) made of glucose units linked by β-1,3 and β-1,4 bonds when sourced from oats — the source chosen by NOPAL LIFE. It is one of the most studied gentle active ingredients for sensitive skin comfort.
Where does beta-glucan come from?
Mainly from oats, but also from yeast and certain mushrooms. In cosmetics, NOPAL LIFE uses a plant-based origin from cereals, obtained by gentle extraction.
How many drops of serum should I apply?
2 to 3 drops on slightly damp skin, morning and evening, before cream. There's no need to apply more: the film forms from the very first drops.
What's the difference with hyaluronic acid?
Both hydrate, but beta-glucan adds a significant soothing dimension and a more enveloping protective film — ideal when skin is both dehydrated and uncomfortable. See the comparative table above.
Is it suitable for reactive skin?
Yes, it's even its preferred area: it's very well tolerated and helps soothe the appearance of burning sensations.
Does cosmetic beta-glucan work like that in food supplements?
No: these are two distinct uses. Ingested beta-glucans (dietary fibers studied for cholesterol or the immune system) fall under nutrition. On this page, it's purely for cosmetic use, for skin hydration and comfort.
What active ingredients can it be combined with?
Colloidal oat, aloe vera, panthenol, prickly pear seed oil. It also pairs very well with retinol routines to soften its use.
