This week - in the biggest TV consumer test ever - Gok Wan tests anti-wrinkle creams to find out which one works best, and he continues with his tour of Naked Britain. He also meets Lisa Mayall (36), who has such low self-esteem that she hasn’t had a hair cut, shaved her legs or arm pits for over two years. She wants to find love but her self confidence is so low that she has resorted to covering up her body in enormous baggy clothes that do nothing for her petite size 8 figure. Can Gok make her look and feel so good - with her clothes on and off - that she’s prepared to strip off and flaunt it all on a public catwalk? Only time will tell.
