Ingredient review
Neohesperidin Dihydrochalcone
INCI: NEOHESPERIDIN DIHYDROCHALCONE
A potent antioxidant and sweetener that helps protect skin from oxidative stress, but is rarely used as a standalone active in leave-on skincare.
In plain English
Neohesperidin dihydrochalcone is a compound derived from bitter oranges. In skincare, it acts as an antioxidant, meaning it helps neutralize free radicals that can damage skin cells. It is also intensely sweet—about 1,500 times sweeter than sugar—so it is sometimes added to lip balms or oral care products for taste. While it can support skin health, it is not a star ingredient in most moisturizers or serums.

Quick decision guide
Useful, but context matters
Neohesperidin Dihydrochalcone 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 Neohesperidin Dihydrochalcone.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic flavonoid glycoside made from neohesperidin, a natural compound found in citrus peels. It belongs to the dihydrochalcone family and is known for its strong antioxidant and sweetening properties.
How it works
It scavenges free radicals (unstable molecules that cause oxidative damage) and may help reduce inflammation. In formulations, it is often used at very low concentrations to provide a sweet taste or to enhance the stability of other antioxidants.
Pros
Potent antioxidant
Neutralizes free radicals that contribute to premature aging and skin dullness, even at low concentrations.
Natural origin
Derived from citrus peels, making it appealing for consumers who prefer plant-based ingredients.
Cons and cautions
Low usage level
Typically used at 0.01–0.1%, so its direct antioxidant effect on skin may be minimal compared to higher-concentration actives.
Limited research in skincare
Most studies focus on its use as a food sweetener; topical benefits are less documented.
Best for
- Anyone looking for gentle antioxidant support in lip balms or oral care
- People who prefer naturally-derived sweeteners in cosmetic products
Use caution if
- Those seeking a proven anti-aging active for leave-on serums
- Individuals with citrus allergies (though risk is very low at cosmetic levels)
Usage tips
Safety summary
Neohesperidin dihydrochalcone is considered safe for cosmetic use at typical concentrations. It has low irritation and sensitization potential. No significant safety concerns have been reported.
Research notes
Research supports its antioxidant and anti-inflammatory activity in vitro. Human studies on topical application are limited, but its safety profile is well established from food use.
Common label clues
- Typical concentration
- 0.01% to 0.1%
- Regulatory status
- Approved as a flavoring agent in the EU and US; generally recognized as safe (GRAS) for food use. In cosmetics, it is allowed without specific restrictions.
- Common uses
