Tetrahydroxy Chalcone 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 Tetrahydroxy Chalcone.
- 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 synthetic derivative of chalcone, a type of flavonoid found in plants like apples and tea. It's made in a lab to be stable and effective in skincare formulas.
How it works
It works by neutralizing free radicals (unstable molecules that can damage skin cells) and by calming inflammatory pathways in the skin. This can help reduce visible redness and support the skin's natural repair processes.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation some stronger antioxidants can cause, making it suitable for sensitive skin.
Calming support
May help reduce visible redness and soothe skin, which is a bonus for those with reactive or rosacea-prone skin.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are less certain.
Less potent than alternatives
Compared to well-studied antioxidants like vitamin C, its protective power may be lower, so it's best used as a supporting ingredient.
Best for
- People with sensitive or redness-prone skin
- Anyone looking for extra antioxidant protection in their routine
Use caution if
- Those with known allergies to synthetic flavonoids (rare)
- People seeking proven anti-aging results may prefer more established ingredients
