What it is
A natural root extract from Periandra dulcis, a plant in the legume family native to South America. It contains compounds like flavonoids and saponins that give it soothing and antioxidant properties.
How it works
It works by reducing the activity of inflammatory signals in the skin, helping to calm redness and irritation. Its antioxidant compounds also neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging.
Pros
Calming effect
Helps reduce visible redness and soothe irritated skin, making it a good choice for sensitive or reactive skin types.
Antioxidant protection
Provides a layer of defense against environmental stressors like pollution and UV damage, which can lead to premature aging.
Cons and cautions
Limited research
Most studies focus on related licorice species (Glycyrrhiza glabra), so the specific benefits of Periandra dulcis are less well-documented.
Mild potency
Compared to other licorice root extracts, this species may have a milder effect, so it may not be as effective for significant hyperpigmentation or inflammation.
Best for
- People with sensitive or reactive skin
- Those looking for a gentle antioxidant
- Anyone wanting to calm occasional redness
Use caution if
- Individuals with known allergies to legumes (rare, but possible)
