The main botanical ingredient is imperata cylindrica, also known as speargrass. One study on rats, which set out to find out whether folkloric claims of anti-inflammatory and analgesic properties were true. It concluded that they were "insignificant". All in all, imperata cylindria appears to have no justification for lurking around in a pot of face cream. More promising is rosa canina, or rosehip, which is high in vitamin C, amongst other things.
Apart from some olive oil, grape seed extract and some vitamin C, there isn't much to write home about. The rest of the ingredients are mostly emollients and suspending agents. PEGs, we know thanks to Claire's well-researched post, are not worth losing sleep over. However, PEG-40 and PEG-8 are known irritants. Of more concern are two forms of aluminum, a neurotoxin. Several studies have shown it can alter the function of the blood-brain barrier. The Risk Assessment Information System, sponsored by the US Dept of Energy, says that it "may be involved" in Alzheimer's and Parkinsons.
