A DIFFERENT KIND OF Education

Skin is not simply a cosmetic surface. It is a biological organ.

Yet most skin-related nutrition education remains...

Superficial & TOPICAL FOCUSSED
Supplement-centric
Disconnected from real physiology
influenced by diet culture and trends

The Diploma in Functional Skin Nutrition & Integrative Nutridermatology® trains you to understand skin health from the inside out: how nutrition, metabolism, inflammation, hormones, oxidative biology and cellular ageing influence what becomes visible on the skin.

Rather than memorising lists of “beauty foods”, you learn to connect mechanisms to outcomes and translate complex science into ethical, evidence-informed strategies for real people.

Look beneath the surface

What actually drives skin dysfunction & ageing?

Metabolic dysfunction

Inflammation / inflammageing

Exogenous & endogenous glycation

impaired autophagy 

Mitochondrial decline

Nutrient insufficiency

Cellular senescence

Gut barrier & microbiome

Oxidative stress

Dermal hypohydration

Hormonal fluctuations

Insulin resistance

Why this Diploma is different

Mechanism-first education for professionals who want to understand why.

01

Skin science first

Recommendations are anchored in cutaneous biology, biochemistry, physiology and metabolic signalling — not wellness trends.

02

Longevity meets dermatology

Explore autophagy, mTOR, cellular senescence, inflammaging, sirtuins and the mechanisms shaping skin ageing trajectories.

03

Food as biological information

Move beyond macros into phytochemistry, nutrigenomics, fermentation, functional foods and dietary signalling.

An emerging evidence base

The Food + Skin Revolution Is Already Underway

The boundaries between nutrition, dermatology, aesthetics and beauty are dissolving. Research is revealing an increasingly sophisticated relationship between diet and skin health, while consumers are embracing beauty from within at unprecedented scale.

Nutritional dermatology is moving from the margins into the scientific conversation — connecting diet, systemic health and cutaneous biology in ways practitioners can no longer afford to overlook.

For practitioners, this convergence is creating an entirely new professional landscape.

Overline text.

Research increasingly connects dietary intervention with dermatological disease, skin ageing and prevention.

 

Dietary interventions have traditionally been an under-appreciated aspect of dermatological therapy. Recent research, however, has found a significant association between diet and some dermatological diseases. Dietary interventions may be recommended as therapy, as in acne. Dietary change may help to prevent skin disease, as in aging of the skin or skin cancer.  

J Clin Aesthet Dermatol. 2014

 

Dietary factors play an essential role in cutaneous homeostasis. Nutrient insufficiency can disrupt cellular function and cutaneous structure, while nutraceutical approaches are increasingly discussed in relation to ageing and dermatoses.

67%

Consumers are also taking a much wider view of 'inside-out beauty' and what can impact their skin health.  67% appreciate the link between good skin health and overall wellbeing

6%

6% of the body’s zinc is present in the skin where it is an important co-factor for several enzymes. (J Nutr. 2000).  Zinc deficiency is linked to alopecia, dry/scaly skin, dermatitis, slow wound- healing and thin hair (Podiatry Today, 2015)

10%

Adults aged >45 years who consumed foods with high antioxidant capacity experienced approximately 10% less photoaging over 15 years than those who ate foods with low antioxidant capacity.

Journal of Investigative Dermatology, 2021

The evolution of skincare

Skin health & esthetic medicine is becoming an inside-out discipline.

The practitioners who understand both sides of that equation — cutaneous biology and nutritional science — are positioned to practise at the leading edge of modern skin health.

Not just education

Graduate with a professional toolkit.

150+ page Practitioner Guidebook

A substantial desk reference for skin health, skin disorders and skin ageing.
