The skin care range is now distributed in 90 countries worldwide, sells in 25,000 skin care centres and is used by 75,000 therapists. Its best selling products include Dermalogica Daily Micro Foliant and the Age smart product range.
The Dermalogica range has a cult following, says Bourke.
International devotees include Courtney Cox and Victoria Beckham. In New Zealand, Shortland Street actresses Fleur Saville and Angela Bloomfield are fans. It is a favourite for removing make-up.
In 2007, Bourke took a step back from the business and at the same time her daughter, Natasha Gee, was given a leadership role in the company. Gee, who has beauty therapy training and a marketing communications degree, worked for Dermalogica in the UK on a graduate/management fast track programme. She opened a flagship store for Dermalogica in London in 2006 and then did the same for her mother's business in Auckland at the Albany Westfield centre in 2007.
Today Dermalogica is stocked in more than 135 skin care centres in NZ, and stockists include Louise Gray in Auckland and Essence Beauty Therapy in Wellington. Its pricing is similar to other prestige retail skin care brands such as Clinique and Elizabeth Arden.
"We treat specific skins, hyper-pigmentation, ageing, acne, sensitivity, teens, men, it's a very big range," says Gee.
The company's turnover in New Zealand is in the millions.
"With Dermalogica, we only have one brand, we don't have a Plan B, we don't have another brand to fall back on," she says.
"Business has been a challenge the last couple of years," adds Gee.
Most skin care companies are marketing their products for their natural properties these days. In response, Dermalogica NZ, based in Albany, has branched out to nine retail locations. It now has counters in four department stores: Smith & Caughey City, Kirkcaldie & Stains, Ballantynes in Christchurch and H & J Smith in Invercargill. The brand is also sold in five Life Pharmacy outlets.
The Albany flagship store closed in February and Dermalogica is now sold at the Life Pharmacy store at Albany.
Dermalogica NZ has also been selling online since 2009, in partnership with the company's stockists.
"We always try to refer the customer back to the stockist for treatment and advice," says Gee. Bourke's role these days is mentoring her daughter and giving strategic advice on the business. She and her husband Brendan own the company 50/50 and a performance-based succession plan is in place to transfer shares to Gee over the next 10 years.
