Pycnogenol

Pycnogenol can be extracted from the French maritime pine (Pinus pinaster). It contains flavonoids and phenolic compounds, which act as potent free-radical scavengers. Immunosuppression and a reduction of the inflammatory sunburn reaction were observed in mice after topical application of pycnogenol 0.05%–0.2%.58 The potential of pycnogenol to provide photoprotection for humans has been investigated for oral supplementation, showing that a significantly elevated UV radiation level was necessary in order to reach 1 minimal erythema dose.[59]
