Ingredient review
Stevia-Turmeric Root Extract
INCI: Steviol Glycosides / Curcuma Longa (Turmeric) Root Extract
A natural antioxidant blend that may help calm skin and fight free radicals, but research on this specific combination is limited.
In plain English
This ingredient is a mix of compounds from the stevia plant (the same one used as a sugar substitute) and turmeric root (the yellow spice in curry). In skincare, it's added to provide antioxidant protection—meaning it helps neutralize unstable molecules called free radicals that can damage skin cells. It may also have soothing properties, potentially reducing redness or irritation. However, because this is a blend, its effects depend on the ratio of stevia to turmeric, and there's not much research on how they work together on skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A combination of steviol glycosides (sweet compounds from the stevia leaf) and an extract from turmeric root (Curcuma longa), both known for antioxidant and anti-inflammatory properties in traditional use.
How it works
The turmeric component provides curcuminoids, which are antioxidants that can help protect skin from environmental stressors like UV and pollution. Steviol glycosides may have mild anti-inflammatory effects and can also act as a natural preservative booster. Together, they aim to support skin health by reducing oxidative stress and calming irritation.
Pros
Natural antioxidant
Helps protect skin from free radical damage caused by UV and pollution, which can lead to premature aging.
Soothing potential
Turmeric is traditionally used to calm redness and irritation, which may benefit sensitive skin types.
Cons and cautions
Limited evidence
There is little published research on the combined effects of steviol glycosides and turmeric root extract in skincare, so benefits are based on individual components.
Staining risk
Turmeric can leave yellow stains on skin or fabrics, especially in higher concentrations, which may be inconvenient.
Best for
- Anyone looking for natural antioxidant skincare
- People with dull or stressed skin from environmental factors
Use caution if
- Those with known allergies to stevia or turmeric
- Individuals using products with high turmeric content who are concerned about staining
Usage tips
Safety summary
This blend is likely safe for most people when used in typical skincare concentrations. The main risks are potential staining and rare allergic reactions to either component. Avoid if you have a known allergy to stevia or turmeric.
Research notes
Research on steviol glycosides in skincare is minimal, while turmeric's antioxidant and anti-inflammatory effects are well-documented in oral and topical studies. The combination lacks direct clinical evidence for skin benefits.
Common label clues
- Typical concentration
- 0.1% to 2% of the blend
- Regulatory status
- Generally considered safe for cosmetic use in low concentrations, but not specifically regulated as a blend by the FDA or EU CosIng.
- Common uses
- Serums, Moisturizers, Masks
- Environmental note
- Both stevia and turmeric are plant-derived and can be sustainably farmed, though sourcing practices vary.
Good to know
- Steviol glycosides are generally recognized as safe (GRAS) by the FDA for use in food, but cosmetic use is less regulated.
- Turmeric extract is often standardized to curcumin content for consistency.
