What is it? A skincare range created by US plastic surgeon Gregory Brown. He established a laboratory to study the healing of severe burns and found that the same molecule - epidermal growth factor (EGF) - that accelerates burns healing also regenerates ageing skin. EGF was a 1986 Nobel Prize-winning find by Stanley Cohen, with whom Brown had worked. What's the spin? ReVive's international relations vice-president Tony Pinho says that Brown realised he could create a product that sped up the turnover time of cells, which decreases as we age, so skin renewed faster. What was his first product? Brown was the first doctor to apply bio-engineered EGF to skincare and was granted a cosmetic patent for EGF in 1994. ReVive was launched in 1997. Before that, Brown had created a cream to give to his patients two weeks before surgery to prep skin for going under the knife. The cream 'created a buzz', says Pinho, and Brown was approached by investors who wanted to back a brand launch. How many products? 'There are only about 15 in the range - we keep it simple,' says Pinho. Each takes a long time to create, due to the scientific process required to formulate an EGF product. 'It's all about the growth factor and ensuring the protein molecule matches the purity of your own molecules. We'd never be able to be a mass-production company' The cost? Here's the bad news. The Intensite Volumising Serum is HK$4,900/30ml, the Arrete Booster C (right) is HK$2,550/15ml, the Masque de Glaise is HK$1,200/5oz, and Peau Magnifique - the latest to hit the shelves - is HK$11,000 for a four-week supply of ampoules. Pinho says it's expensive because 'it's been in the works for a long time.' In studies, there was a 40 per cent reduction in the signs of ageing within 30 days, he says. Peau Magnifique also contains telomerase, an enzyme discovered in the 1970s and used to fight cancer, but which also has skin-tightening properties. 'This is the only product in the world to have this in it,' he says. It's said to re-activate dormant skin stem cells, which means they can then 'stop DNA fragmentation to turn the clock back'.
