When Hanna Sillitoe appeared on Dragons' Den, every Dragon offered her investment. In her first book, Radiant, she shares the lifestyle changes and recipes that transformed her life.

For more than 20 years, Hanna suffered from severe psoriasis, eczema and acne - sometimes so badly that the only way to stop herself scratching was to wrap her body in clingfilm. When her doctor suggested the only remaining course of treatment was chemotherapy, she took matters into her own hands and cured herself through a change in diet and lifestyle.

Beginning with a juice cleanse, Hanna takes you through a range of delicious, skin-loving meals including Turmeric and Ginger Chia Pudding, Immunity Ramen, Beet Burgers and even Clean Tiramisu. She also shows you how to create homemade beauty products, including an Avocado and Honey Facemask and Rosemary and Lemon Salt Scrub, which have gone on to inspire the eponymous skincare range for which she secured funding on BBC 2's Dragons' Den.

Uplifting and inspiring for those who have been searching for the answer to seemingly unsolvable skin complaints, Hanna's programme is also suitable for those simply looking to improve their overall health and complexion. It's a recipe for good health and clear skin, from the inside out.

Hanna is also the author of Skin Healing Expert: Your 5 pillar plan for calm clear skin
