The Dietary Skin-Ageing Index

Imagine being able score how skin-ageing your clients diets are with precision and confidence? 

Introducing the Dietary Skin-Ageing Index™ (DSAI). The DSAI was developed in 2024 from over 15 years of distilling and unifying the nutritional research done on all of the separate ageing pathways.

The DSAI seeks to both unify all ageing pathways into one specific anti-ageing dietary pattern while at the same time providing a comprehensive scoring system that practitioners can use to assess each ageing pathway in order to see areas of ageing need. the most work and also to create an overall ageing score for the client.To some extent the current DSAI is not the finished product, as more ageing pathways are discovered and studied scientifically, the DSAI will expand to include these.

Micro-scoring for precision functional nutrition strategies

The DSEI™ can be used to give an overall score of how anti-ageing or pro-ageing a client’s diet is but you can also use it to analysis specific ageing pathways for certain skin issues and disorders.

You will also be able to see the scores for each of the 12 skin-ageing pathways which gives you the insider-knowledge to know which ageing pathways to treat first. It allows you to effectively triage your dietary interventions and create targeted nutritional coaching programs that will give huge results to your clients.

No more guesswork! The Dietary Skin-Ageing Index™ gives you and your client the much-needed clarity to help you both work together knowing that the dietary solutions will yield results. The DSAI is the underlying method behind The Facelift Diet® and The Facelift Diet® Licensed Coach Diploma. All of our coaches are trained to use the Dietary Skin-Ageing Index™ because it's the ONLY tool available that assesses diets for skin-ageing. It's essential.

Scoring data across all 12 ageing pathways

The reason why many nutritional approaches to skin-ageing fail is because of three main reasons:
  1. As a practitioner you are only trying to assess one or two of these skin-ageing pathways. For example: just gut-dysbiosis and oxidative stress. But all 12 need to be deactivated for a dietary approach to make a big difference.
  2. As the practitioner you don't know which of the skin-ageing pathways are causing the most damage, they might be working on lengthening the telomeres when it's actually Glycation causing most of the damage. Without the DSAI™ you'd never know.
  3. You're not using an evidence-based scoring system to inform you about the skin-ageing potential of your client's diet, you're just guessing. 


Slowing down and even reversing biological age at the skin and cellular level requires a depth of knowledge and meticulousness not needed in more simpler areas of nutrition (weightloss, for example).

A proper protocol is required and this is why I invented the DSAI™ - it'll revolutionise how you work with your clients on their skin

How can you use the DSAI in your business?

As a Nutritionist, Dietician or Health Coach you will learn to use the DSAI toolkit as part of The Facelift Diet Diploma (9-month group program). If you don't wish to become a full TFD Coach you can request to license the DSAI™ for your specific industry:

  • Beauty /skin therapy
  • Supplement sales / health store
  • Nutricosmetic formulation
  • Health food eatery / juice bar
  • Skincare formulator
