A study from the US and Australia has shown that the essential oil citronello, used to purify cosmetics, can be used to treat a range of skin conditions including eczema, psoriasis and psorific acne.
The study, which is published in the journal PLOS ONE, involved participants from two clinics in Sydney and Adelaide.
Participants were given a 30ml (2oz) spray of citronellyzed essential oil.
It is a type of essential oil which contains the flavonoid lecithin, which acts as a moisturiser and antioxidant.
It is also used in cosmetics.
The study also found that a 30-day course of citronellol (a mixture of citrate and citronelli) improved skin elasticity, improved wound healing and improved facial skin elasticities.
However, the study did not find evidence of efficacy for use in the treatment of eczemas, psoriatic acne or other conditions.
The researchers said that they wanted to find out whether the essential oils could be used in combination with other cosmetics.
“We are now using this research to further develop our approach in the skin care industry and to further evaluate whether it could be combined with other topical ingredients to treat dermatitis,” said Dr Karen Lea, who led the research at the Centre for Skin and Environmental Sciences at Monash University in Australia.
“Our study is an important step towards understanding the potential of citronsol in skin care,” she said.
The essential oil can be extracted from the flowers of melrose essential plant.
It contains a mixture of compounds, including essential oil of lecITHIN, which contains hyaluronic acid.
The research also showed that citronelol also had antimicrobial properties.
The main study was funded by the Australian Research Council (ARC) and the National Health and Medical Research Council, with support from the National Science Foundation and the Australian National University.
