What it is
A natural extract derived from the bark of the Hibiscus syriacus plant, containing compounds like flavonoids and phenolic acids that have antioxidant and anti-inflammatory activity.
How it works
The extract works by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells), thereby reducing oxidative stress. It may also help calm minor skin irritation due to its anti-inflammatory compounds.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, suitable for sensitive skin.
Soothing potential
Contains anti-inflammatory compounds that may help calm redness or minor irritation.
Cons and cautions
Limited research
Most evidence comes from lab studies; human trials on skin benefits are scarce.
Low potency in formulas
Often used at low concentrations, so its effects may be subtle compared to stronger antioxidants.
Best for
- Anyone looking for a gentle antioxidant boost
- People with sensitive or reactive skin who want extra protection
Use caution if
- Those with known allergies to Hibiscus or Malvaceae family plants (rare)
