This is a professional skin nutrition certification, not a beauty course

The Diploma in Integrative Nutridermatology® program is an advanced, mechanism-driven training designed for practitioners and serious students who want to understand
  • how and why skin ages.
  • what drives premature skin ageing and skin disorders biologically
  • how nutrition influences skin structure, function and repair
  • and how to intervene strategically, ethically and effectively.
This course treats skin as a biological organ, not a cosmetic surface.

Because skin disorders and skin-ageing are not caused by a lack of collagen powder, vitamin supplements or the wrong moisturiser

THEY'RE DRIVEN BY...

 Metabolic dysfunction

 Inflammation

 Hormonal signalling changes

 Oxidative stress

 Impaired autophagy

 Glycation

 Mitochondrial decline

 Nutrient insufficiency

 Accumulating cellular waste

Yet most skin-related nutrition education remains:

Empty space, drag to resize

Superficial

Supplement-centric

Disconnected from real physiology

Heavily influenced by diet culture and trends

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.

What makes this course fundamentally different from all other skin nutrition education?

Empty space, drag to resize

🔬 It is mechanism-first

Every recommendation is anchored in:
  • Skin biology
  • Biochemistry
  • Metabolic signalling
  • and cellular-ageing science
You will understand why an intervention works and not just that it does.

🧠 It integrates longevity science into skin health

You will explore how pathways such as:
  • IGHF-1 and mTOR
  • Autophagy 
  • Cellular senescence
  • Interleukins and 'inflammaging'
  • Sirtuins
...AND You will understand how these directly influence skin structure, collagen integrity, inflammation, dermatoses and ageing trajectories.

🥗 It treats food as biological information

This course goes far beyond macronutrients.
  • Functional Skin Nutrition
  • Dietary acid load (DAL)
  • Fibre and fermentation
  • Phytonutrition
  • Botanical compounds and formulae
  • Nutrition Biochemistry 
and how foods act as signals that either accelerate or decelerate skin ageing.

🎯 It teaches assessment before intervention

Through the proprietary DSAS™ (Dietary Skin-Ageing Score System), you will learn to:
  • Identify dominant skin-ageing and dermatoses drivers
  • Recognise patterns rather than symptoms
  • Prioritise interventions logically & sequientially
  • Avoid scatter-gun supplementation and unnecessary dietary restrictions
This is clinical reasoning + personalised nutrition, not 'copy & paste' protocols

The Diploma in Integrative Nutridermatology®  is not designed as an entry-level nutrition course.

✅ Who this certification is for
  • Nutritionists, nutritional therapists & dieticians
  • Functional / integrative practitioners
  • Health professionals working with skin or ageing
  • Aesthetic professionals wanting deep nutrition literacy
  • Students and graduates from aesthetics or health who are seeking a skin specialisation
❌ Who this PROGRAM is NOT for
  • Total beginners to nutrition or physiology
  • Those seeking cosmetic or beauty-only training
  • Anyone wanting protocols without understanding mechanisms
  • Supplement-led or strict diet approaches (keto, carnivore, 5:2 etc)

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 – an increase of 13% between 2018 and 2021

As a Certified Nutridermatologist™ you will be able to:

  • Explain skin ageing and skin disorders as a systems-level biological process
  • Identify nutritional and metabolic drivers of premature ageing and dermatoses
  • Understand collagen loss, dehydration, ageing and inflammation mechanistically
  • Critically evaluate - and even formulate - nutricosmetics and natural skin supplements
  • Design evidence-based, personalised nutrition strategies for skin-health and skin-rejuvenation
  • Translate complex science into clear, ethical recommendations
  • Work confidently at the intersection of nutrition, skin biology and bio-ageing science.

I actually learned a lot more than I thought I would. The process of collagen biosynthesis is so clear now, I can make a picture in my head of everything that needs to happen.

Explanation of food influence on our skin health, but not just the skin because we can copy and paste this knowledge on our whole body because mechanism is the same. It will be so much easier to help my own clients :)

Dietary factors play an essential role in cutaneous homeostasis since they supply the nutrients necessary for good cellular functioning. Any shortage of these elements can lead to dysfunctions of the cutaneous structure, often hard to identify, since the clinical condition is oligosymptomatic. Nutraceuticals are associations of nutrients with benefits and synergistic effects. They act not only in response to any minor shortage of micronutrients but also in phenomena at the cellular level, associated with aging, dermatoses, and the cellular cycle

Frequently asked questions

When does the program start?

As soon as pay your fees you'll be automatically enrolled to our online classroom and student portal and can start your training immediately.  You'll also be able to make use of all the facilities:
  • The community area for discussion groups and friendship
  • The 'best resources' area for all of your saved notes and access to our science library
  • There's a 'start' page which has our orientation video to help you navigate around the website and use all of the facilities. 


Is it accredited?

As a school we are proud to be accredited by these prestigious 3rd party professional bodies:

  • IPHM (International Practitioners of Holistic Medicine)
  • IGCT (International Guild of Complementary Therapists) 
  • CMA (Complementary Medicine Association)

As a Skin Nutrition Institute graduate YOU will be eligible to join IPHM, IGCT and CMA to enjoy such perks as being listed on their practitioner directories and getting special deals for your practitioner indemnity insurance.

Star Khechara is also an active member of the The Nutrition Society and Plant-Based Health Professionals

Are there any ongoing fees or software costs?

Yes. While there are no ongoing fees payable to us after enrolment, you will need to use 2 third-party tools to work efficiently and deliver professional-level client services.


1. Cronometer

You will need a Cronometer account to analyse client dietary intake. Cronometer offers a free version, which is suitable for basic use. However, for maximum efficiency and more advanced dietary analysis features, a Cronometer Pro account is recommended. You can view Cronometer Pro pricing here:
https://cronometer.com/pro/

2. Dietary Skin-Ageing Score (DSAS)
The Dietary Skin-Ageing Score (DSAS) is an advanced proprietary assessment tool developed and owned by us. It is delivered via specialist assessment software which securely hosts the tool and transforms client data into a comprehensive, practitioner-ready report.

To use DSAS at practitioner level — including access to the automatically generated, downloadable client PDF reports — you will need access to the professional business-level software plan used to run DSAS (currently $99 per month).

These PDFs are a core part of the professional workflow taught in the diploma and are where DSAS really shines. Each report is generated instantly and essentially writes itself, providing clients with a clear, personalised breakdown that includes:

  • Their overall Dietary Skin-Ageing Score

  • The ageing pathways most strongly activated for them

  • A clear explanation of each pathway, what it means, and why it matters

  • The client’s individual score for each pathway

  • Practical, nutrition-focused steps they can take to reduce their score and support healthier skin ageing


This allows you to deliver a highly polished, evidence-informed client report in minutes, while still maintaining full professional oversight and interpretation.


Access to the correct software plan and setup instructions (including use of our partner access link) are provided to students during the training.

NB: Prices are correct at time of writing.

Please note: This is a high-level precision nutrition service and should be priced accordingly. A minimum fee of $250 USD per client is recommended, covering an in-depth consultation, full dietary audit and analysis, and the client’s personalised Dietary Skin-Ageing report. At this level, a single client per month comfortably covers the software investment.


How long will it take to finish the course?

This advanced program will take you between 6-12 months to completed (depending on prior knowledge of the topics and how much time you have to study. You do get 3 years to complete the program then lifetime access to the modules and graduate materials after graduation.

Do you offer team discounts?

We can offer substantial discounts on group enrolments (especially when there are more than 5 participants). Send us an email with all the information: hello@skinnutritioninstitute.com

Can I license this course for my team of staff?

We can offer a corporate license for this program, please contact us at hello@skinnutritioninstitute.com

What happens after I've paid?

Once you've enrolled you'll be prompted to create your login and password so you can access our Virtual Learning Environment (VLE). Once inside you can move around and access everything you need:
  • There's a course area where your courses will be
  • There's a community area for discussion groups and friendship
  • There's a 'best resources' area for all of your saved notes and access to our science library
  • There's a 'start' page which has our orientation video to help you navigate around the website and use all of the facilities. 

Is this course suitable for me?

This Diploma-level program is best for professionals and practitioners in the nutrition and esthetics fields: 
  • Estheticians
  • Dermatologists
  • MediSpa staff
  • Skin Therapists

  • Dieticians
  • Nutritionists
  • Naturopathic Doctors

How will I use this Nutridermatology® knowledge with my own clients?

In many jurisdictions, particularly in the United States, the provision of personalised nutritional advice is legally restricted to Registered Dietitians, Registered Nutritionists or medical doctors. The distinction lies in the term personalised.

As many of our students come from non nutrition backgrounds, the Diploma includes an extensive library of licensed, ready to use educational materials that graduates may use with clients within a professional and legally appropriate framework.

These resources are designed to support practitioners in guiding clients towards nutritional strategies that promote healthy, resilient and rejuvenated skin without requiring a degree in Nutritional Medicine.

As with any client facing practice, graduates are responsible for understanding the legal and regulatory requirements of the country, state or locality in which they operate and for working strictly within their permitted scope of practice.

Is there a payment plan?

If you want to move through the diploma quickly at your own pace you need to choose the 'fast-track' option where you pay the fees in full. 

You can also choose the 'pay as you go' option with a 12 month payment plan
  • Monthly payments required to maintain access
  • Graduation only available once balance is cleared
  • Certificate issued after final payment

On the payment form you need to select to pay using your credit card (this symbol  ) then you'll see a dropdown box where you can select either:
  • Pay once (pay in full)
  • Payment plan (using your card


 Please note that students won't be allowed to graduate while in debt to Skin Nutrition Institute so if you select a 12 month payment plan you'll need to take the full 12 months to study as you won't be allowed to finish before your payment plan does.

What course credits will I get?

This Diploma in Functional Skin Nutrition, Dietary Age-Reversal & Integrative Nutridermatology® is approximately equal to 100CPD* Hours and 10 CEU**

These credits will be visible on your printable certificate when you pass your final exam and graduate from the course
