Spear’s Review

A dual-qualified nutritionist and dermatologist based at The Cleveland Clinic, Dr Thivi Maruthappu’s practice is centred around the interaction between skin health and diet.

Taking a holistic approach, Maruthappu considers nutrition and lifestyle factors – alongside personalised skincare and medical treatments where appropriate – when treating conditions such as eczema, psoriasis, hair loss and acne. Her 2023 book, SkinFood, draws on her 15 years of experience and extensive academic research to make recommendations for healthy skin, which include a diet rich in omega-3 fatty acids (such as oily fish and walnuts), anti-inflammatory spices such as cardamom and turmeric, and prebiotic foods including asparagus and onions. 

Frequently called on by media publications to advise on anti-ageing treatments, Maruthappu is a member of the British Association of Dermatologists, the Nutrition Society and the Royal Society of Medicine.
