What it is
Citrus Depressa Peel Extract is derived from the peel of shikuwasa, a small tart citrus traditional to Okinawa, and is naturally rich in flavonoids. In cosmetics it is used as an antioxidant-supporting and skin-conditioning botanical. It is typically present at low concentrations as a supporting plant extract.
Safety & warnings
At the low levels used in cosmetics it is generally well tolerated. As a citrus peel extract it may carry trace fragrance constituents such as limonene; furocoumarins associated with phototoxicity are mainly concentrated in cold-pressed peel oils rather than extracts, but those with citrus sensitivities may wish to patch test.
