What it is
Trihydroxychalcone is a type of chalcone, a class of natural compounds found in many plants. It is often extracted from licorice root or other botanical sources. In cosmetics, it is used for its antioxidant and anti-inflammatory benefits.
How it works
Trihydroxychalcone works by donating electrons to unstable free radicals, neutralizing them before they can cause oxidative damage to skin cells. It also inhibits certain enzymes involved in inflammation, helping to reduce redness and swelling. This dual action makes it effective for both protection and soothing.
Pros
Gentle antioxidant
Trihydroxychalcone is mild enough for sensitive skin while still providing effective protection against free radicals from pollution and UV exposure.
Soothing properties
It helps calm redness and irritation, making it a good addition to products for reactive or inflamed skin.
Cons and cautions
Limited research
While promising, there are fewer studies on trihydroxychalcone compared to more established antioxidants like vitamin C or E.
Potential allergen
As a plant-derived compound, it may trigger allergic reactions in individuals with specific plant sensitivities, though this is rare.
Best for
- People with sensitive or easily irritated skin looking for a gentle antioxidant
- Anyone wanting extra protection against daily pollution and sun damage
Use caution if
- Individuals with known allergies to licorice or related plants should patch test first
