Millionaire Tycoon Lord Sugar invested in Susan's Tropic Skin Care after last year's show, where she finished third in the competition.
But despite missing out on Lord Sugar's original £250,000 investment, the determined youngster persuaded him to invest anyway.
The pair yesterday launched a new range at a trade show Earls Court yesterday, with Lord Sugar explaining: “She didn’t leave me alone until I invested in her.”
It comes a week after Lord Sugar and last year's Apprentice winner Tom Pellereau announced his business venture with Lord Sugar, the Stylfile, a curved shaped nail file.
A new series of The Apprentice starts on Wednesday on BBC One.
