When Baulkham Hills friends Louise Ferguson and Kate Cotton had a lightbulb moment while on maternity leave they didn't know they had stumbled upon a goldmine.
Their tanning and cellulite cream Skinny Tan not only made more than $100,000 profit in its first six months of sales in Australia, but also generated £250,000 ($450,000) from online sales five weeks after breaking into the British market.
After six months of research to create a "dual effect" cream they had a prototype with guarana, which contains caffeine (believed to reduce cellulite), and with a naturally derived version of glycerone, found in most tanning creams.
"Our formula was an Aussie first when it came out in 2012," Mrs Ferguson said.
"We tested about 20 samples before finding a formula that doesn't look orange, smells good, isn't drying and can be seen when applied".
The mothers were featured in the BBC Two show Dragon's Den last year.
They left with £60,000 ($118,000) from investors Piers Linney and Kelly Hoppen, who in return got 5 per cent of the company each.
"That was one of the biggest moments for us," Mrs Ferguson said.
"We broke the record by having all the dragons come in with nine different business offers."
