Hibiscus Sabdariffa Flower Extract
Hibiscus Sabdariffa Flower ExtractAntioxidant
Roselle hibiscus extract — in lab cells it curbed UV damage signals, collagen-breaking enzymes and pigment enzymes.
What it does
It’s used as an antioxidant. In one lab study, a water extract of the calyx (the cup around the flower) lowered the free radicals UVB light made in skin cells. It also lowered enzymes that break down collagen, raised collagen and blocked the enzyme that starts pigment. All of it was in cells and test tubes, not skin.

No animal or person was tested, so what it does in a skincare product is not known.Li 2020 · J Sci Food Agric ↗
