Ingredient review
Hydrolyzed Glucosyl Stevioside
INCI: Hydrolyzed Glucosyl Stevioside
A mild, sugar-modified stevia derivative that helps hydrate skin without the sweetness or stickiness of raw stevia.
In plain English
Hydrolyzed glucosyl stevioside is a modified version of a compound found in the stevia plant. It is processed to add sugar molecules, which makes it water-loving and able to attract moisture to the skin. Unlike the stevia you might use as a sweetener, this ingredient is not sweet and is designed specifically for skincare. It helps keep skin hydrated and feels light, making it a good option for people who want gentle moisture without heavy oils or silicones.

Quick decision guide
Useful, but context matters
Hydrolyzed Glucosyl Stevioside is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Glucosyl Stevioside.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic humectant derived from stevioside, a natural glycoside from the Stevia rebaudiana plant. Through enzymatic hydrolysis and glucosylation, sugar units are added to improve its water solubility and skin compatibility.
How it works
It sits on the skin's surface and draws water from the environment and deeper skin layers into the outer layer, helping to maintain hydration. It also forms a thin, non-sticky film that can temporarily reduce water loss.
Pros
Gentle hydration
Provides moisture without irritation, making it suitable for sensitive or compromised skin barriers.
Lightweight feel
Does not leave a greasy or heavy residue, so it works well under makeup or sunscreen.
Cons and cautions
Limited research
There are fewer peer-reviewed studies on this ingredient compared to classic humectants like glycerin, so its long-term effects are less understood.
Potential tackiness
In high concentrations or certain formulations, it can feel slightly sticky on the skin.
Best for
- People with normal to dry skin seeking light hydration
- Those with sensitive or reactive skin who want a gentle humectant
Use caution if
- Individuals looking for a heavy occlusive moisturizer
- Those with known allergy to stevia or related plants (rare)
Usage tips
Safety summary
Hydrolyzed glucosyl stevioside has a low irritation and comedogenic risk based on available data. It is considered safe for use in leave-on and rinse-off cosmetics at typical concentrations. However, comprehensive long-term safety studies are limited, so it is best used as part of a balanced formulation.
Research notes
Most evidence comes from manufacturer safety data and in vitro studies showing humectant properties. Peer-reviewed clinical studies on human skin are scarce, placing this ingredient in the 'emerging' evidence category.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, though not specifically listed as a regulated active ingredient.
- Common uses
- Serums, Moisturizers, Toner, Sheet masks
- Environmental note
- Derived from renewable plant sources; the enzymatic modification process is considered relatively eco-friendly compared to fully synthetic alternatives.
Good to know
- This ingredient is often used in 'clean beauty' formulations as a natural-derived alternative to synthetic humectants.
- It is not the same as stevia extract used in food; the hydrolysis process changes its properties significantly.
