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 Trihydroxydihydrochalcone.
- 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
Trihydroxydihydrochalcone is a type of dihydrochalcone, a class of flavonoids naturally occurring in plants. It is often extracted from the bark of the *Ilex paraguariensis* (yerba mate) tree or other botanical sources. In cosmetics, it is used for its antioxidant and anti-inflammatory properties.
How it works
This ingredient works by neutralizing free radicals—unstable molecules that can damage skin cells and accelerate aging. It also inhibits certain enzymes involved in inflammation, helping to reduce redness and soothe sensitive skin. Additionally, it may support the skin's natural repair processes by promoting collagen synthesis, though more research is needed to confirm this effect.
Pros
Gentle antioxidant
Unlike some stronger antioxidants that can sting or irritate, trihydroxydihydrochalcone is very mild, making it suitable for sensitive or rosacea-prone skin.
Soothing properties
It can help calm redness and inflammation, which is especially helpful after exfoliation or sun exposure.
Cons and cautions
Limited research
Most studies are lab-based or small-scale; large human trials are lacking, so its long-term benefits are not fully proven.
Lower potency
Compared to well-studied antioxidants like vitamin C or ferulic acid, its protective effect may be weaker, so it's best used as a supporting ingredient.
Best for
- People with sensitive or reactive skin looking for a gentle antioxidant
- Those wanting to add extra environmental protection to their routine without irritation
Use caution if
- Anyone allergic to flavonoids or plant extracts from the yerba mate family (rare)
Usage tips
Safety summary
Trihydroxydihydrochalcone is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and allergy potential, making it suitable for most skin types. As with any new ingredient, patch testing is recommended for those with known plant allergies.
Research notes
Current evidence is primarily from in vitro (lab) studies showing antioxidant and anti-inflammatory activity. A few small human studies suggest potential for reducing redness and improving skin tone, but larger clinical trials are needed to confirm efficacy and long-term benefits.
