What if almost everything you have been taught about skin was built for only half of humanity?
Every human being alive carries roughly the same number of pigment-producing cells. The difference between the darkest and the lightest skin is not how many you have. It is what those cells make, and how it is packaged. Yet the science of skincare, the advice from dermatologists, and the products on every shelf were built on a framework that cannot see most of the world's skin. Melanin is the book that explains why, and what the real biology says instead.
Olusola Idowu PhD, an scientist and founder of a Newcastle biotech laboratory, did not set out to write a book. He set out to find products that worked for his own family: a nationally ranked swimmer daughter with textured hair, a son whose skin scarred from the smallest injury, another with acne and eczema at once, a third with uneven tone from years of outdoor sport, and a wife with reactive skin the beauty industry insists does not exist. Six skin stories. One family. No framework that fit any of them.
From there, Melanin takes apart the single most influential idea in modern skincare: the Fitzpatrick scale. Designed in 1972 to dose ultraviolet therapy for a handful of patients, it quietly became the map for everyone's skin, and it gets melanin-rich skin profoundly wrong.
Across eight sharp, story-led chapters, readers will discover why "skin of colour" is a biological reality rather than a marketing phrase and what actually differs at the cellular level; why sun, sunscreen, and vitamin D guidance built for northern Europe fails darker skin at high latitudes; what keloid scarring, hyperpigmentation, melasma, and dark spots reveal that the standard skin-type chart cannot predict; and why acne and eczema on Black and brown skin remain among the most under-researched conditions in dermatology.
Written in the voice of a brilliant friend who happens to be a scientist and a father, Melanin is rigorous without being cold and personal without losing the evidence. Every claim is grounded in peer-reviewed research and original laboratory work.
The author brings rare authority to the subject. Over fourteen years he has advised many of the world's largest cosmetics companies on the science they were missing, built an award-winning AI ingredient-discovery platform, founded a haircare brand recognised at the Pure Beauty Awards, and given evidence to the UK Parliament on personalised skincare for under-served skin.
Melanin is the first book in a landmark trilogy on the biology we share and the differences that matter: Melanin, Rooted, and Ageing.
Read it, and you will never look at your own skin, or anyone else's, the same way again.
