A leaf extract protects keratinocytes from UVB
Laboratory50% ethanolic extractHaCaT human keratinocytesUVB irradiation
Without cytotoxicity up to 1,000 µg/mL, the extract limits free radicals, cell damage and cell death, and raises the expression of the antioxidant enzymes SOD-1, GPx and catalase. UVB raises MMP-1, MMP-3 and MMP-9 and lowers type I collagen and elastin: the extract attenuates these effects. Cell culture result10.
An antioxidant profile that depends on origin
Laboratory2 extracts and 1 infusionParaguayan leaves, 4 harvest datesFRAP, DPPH, ORAC and PCL assays
The antioxidant profile is favorable and better than that of leaves from Senegal. Some samples protect avobenzone from photodegradation better than commercial filters. Lab study8.
A moisturizing cream tested on 30 volunteers
Clinical trialMicrocapsules of α-tocopherol and moringa extractMoisturizing cream60 days, 30 healthy volunteersAgainst a commercial product
The extract, obtained by supercritical CO₂ and rich in α-tocopherol, is microencapsulated with synthetic α-tocopherol. According to the authors, results are comparable or better than the commercial product. The trial tests a combination, not the extract alone11.
An extract in a model cleansing gel

Strong free radical scavenging capacity. Up to 5%, the extracts had a favorable effect on cell proliferation and metabolism. Added to the model formula, they could reduce irritation. Lab study9.
Clinical evidence still to be strengthened
Review2015 reviewCreams with plant extracts
Moringa is among more than twenty botanicals tested in cream. The authors conclude that evidence-based studies are still needed for anti-aging effects12. A 2024 review lists the compounds and the commercial moringa cosmetics: it is an inventory, not a trial7.
