Ms Sabrina Tan, the founder of Skin Inc, which has been described as one of Singapore's most successful skincare firms and is sold in about 200 cities worldwide, was an average student at Gongshang Primary School, scoring around 200 points in the Primary School Leaving Examination (PSLE).

After getting a Diploma in Business Administration from Ngee Ann Polytechnic, the 44-year-old followed that with a degree in economics and business management from the University of London through the Singapore Institute of Management. "I blossomed much later academically," she said.
