Ingredient review

Ziyu Glycoside II

INCI: Ziyu Glycoside II

A plant compound with early research suggesting antioxidant and soothing benefits, but more human studies are needed to confirm its effectiveness in skincare.

In plain English

Ziyu Glycoside II is a natural compound found in the root of a plant called burnet (Sanguisorba officinalis). In skincare, it's added to products like serums and creams because early lab studies suggest it may help calm skin and fight free radicals (unstable molecules that can damage skin cells). Think of it as a gentle helper that might support your skin's defenses, but it's not a star ingredient yet—more research is needed to know how well it works on real skin.

The ingredient may be promising, but claims should be treated more cautiously.

What it is

Ziyu Glycoside II is a triterpenoid saponin, a type of plant chemical, extracted from the root of Sanguisorba officinalis (also known as burnet or great burnet). It has been used in traditional medicine and is now being explored in cosmetics for its potential skin benefits.

How it works

In a cosmetic product, Ziyu Glycoside II is thought to work by neutralizing free radicals (antioxidant activity) and by reducing the production of certain inflammatory signals in skin cells, which may help calm irritation. However, these effects are based mostly on lab studies, and how well it penetrates or works in a finished product on human skin is not yet fully understood.

Pros

Natural origin

Derived from a plant root, appealing to those who prefer botanical ingredients in their skincare routine.

Potential soothing effect

Early lab studies suggest it may help calm skin irritation, which could be beneficial for sensitive skin types.

Cons and cautions

Limited human evidence

Most research is in test tubes or animals; there are very few human studies confirming its benefits in real-world skincare.

Low typical concentration

It's often used at very low levels in formulas, which may mean any effects are subtle or hard to notice.

Best for

People with normal to combination skin looking for gentle antioxidant support
Those interested in plant-based, traditional medicine-inspired ingredients

Use caution if

Anyone with known allergies to Sanguisorba officinalis or related plants
Those seeking proven, high-efficacy ingredients with strong clinical backing

Usage tips

Look for it in serums or creams that also contain other well-studied soothing ingredients like niacinamide or panthenol.

Patch test before full use, especially if you have sensitive skin or plant allergies.

Safety summary

Ziyu Glycoside II appears to have low irritation and comedogenic risk based on its chemical nature and typical use levels. However, due to limited safety data, it is best used in low concentrations and as part of a broader formula. No major safety concerns have been reported, but individual allergies are possible.

Research notes

Research on Ziyu Glycoside II is in early stages. A few lab studies show antioxidant and anti-inflammatory activity, but there are no robust clinical trials on human skin. Its effectiveness in skincare remains unproven.

Common label clues

Typical concentration: Typically used at low concentrations, often below 1%
Regulatory status: Not specifically regulated by the FDA as a cosmetic ingredient; it is generally considered safe for topical use at low concentrations.
Common uses: Serums, Moisturizers, Soothing creams
Environmental note: Sanguisorba officinalis is a widely distributed plant, but sustainable sourcing practices should be confirmed with the manufacturer.

Good to know

Ziyu Glycoside II is sometimes listed as 'Ziyuglycoside II' on ingredient labels.
It is not a common ingredient, so it may be found in niche or Asian beauty products.
