What it is
A natural extract derived from the calyx (the outer husk) of Physalis peruviana, also known as golden berry or Cape gooseberry. It is rich in bioactive compounds like flavonoids, withanolides, and polyphenols.
How it works
In a cosmetic product, it acts as an antioxidant, scavenging free radicals that can damage skin cells. It also has anti-inflammatory properties that may help calm redness and irritation, and it supports the skin's natural barrier function.
Pros
Gentle antioxidant
Provides free radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and inflammation, which is beneficial for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; human skin studies are scarce, so effectiveness is not fully proven.
Rare allergen risk
As a plant extract, it may cause allergic reactions in people sensitive to nightshade family plants, though this is uncommon.
Best for
- People with dull or stressed skin looking for antioxidant support
- Those with sensitive or easily irritated skin who want a gentle soothing ingredient
Use caution if
- Individuals with a known allergy to Physalis species or related plants (Solanaceae family)
Usage tips
Safety summary
