Feed Your Skin From Within
By Julia Hart, The Electric Facialist
Why Nutrition Is One of the Most Powerful Anti-Ageing Treatments You'll Ever Invest In
When people think about improving their skin, they usually think about skincare.
The right cleanser.
A vitamin C serum.
Retinol.
Maybe even a facial treatment.
All of these can make a tremendous difference, but over the years I've become increasingly fascinated by something else...
What happens inside the body.
Because beautiful skin doesn't begin with a moisturiser.
It begins with healthy cells.
Every single skin cell is built from the nutrients we eat, protected by antioxidants, powered by healthy mitochondria and supported by an intact skin barrier. If we truly want healthier, stronger, more resilient skin, we have to nourish it from within as well as care for it from the outside.
This is why nutrition has become such an important part of my philosophy.
Good skincare and great treatments can transform your skin, but they're even more powerful when they're supported by healthy nutrition.
Your Skin Is Built From What You Absorb
We've all heard the phrase...
"You are what you eat."
I actually think there's a better way of saying it.
You become what you consistently absorb.
Every meal provides the vitamins, minerals, proteins, healthy fats and antioxidants your body uses to repair itself.
Those nutrients help build collagen.
Strengthen cell membranes.
Support your skin barrier.
Protect your cells from oxidative stress.
Reduce inflammation.
Repair everyday damage.
And because your skin is your body's largest organ, it reflects those choices remarkably well.
Healthy skin is rarely an accident.
It's usually the result of thousands of small decisions repeated every day.
What We Can Finally Measure
This is one of the reasons I'm so excited by the arrival of the Nu Skin Prysm iO.
For years we've known that eating colourful fruits and vegetables supports healthy skin.
We know antioxidants help protect our cells.
We know oxidative stress speeds up ageing.
But until recently, it was incredibly difficult to know whether our nutrition and supplements were actually making a measurable difference.
The Prysm iO changes that.
Using advanced Spectral Rai™ Technology, it measures carotenoids stored within the skin in just 15 seconds, giving you a simple colour-coded Prysm Score that reflects your antioxidant status.
"Healthy skin is measurable." This could eventually encompass hydration, barrier function, antioxidants, collagen, skin quality, and even biological ageing.
Instead of wondering whether your healthy habits are working...
You can actually begin to measure them.
To me, that's incredibly exciting.
Why Antioxidants Matter
Every day our bodies produce free radicals.
This is completely normal.
However, pollution, UV exposure, smoking, poor sleep, chronic stress and highly processed diets can all increase oxidative stress.
Over time this can contribute to:
- Premature skin ageing
- Collagen breakdown
- Increased inflammation
- Reduced skin resilience
- Dullness and uneven skin tone
Antioxidants help neutralise these free radicals before they can cause damage.
Think of them as your body's natural defence system.
The stronger your antioxidant defences, the better equipped your cells are to cope with everyday life.
Eat the Rainbow
One of the simplest pieces of nutritional advice I give clients is...
Eat as many different colours as possible.
Different coloured fruits and vegetables contain different protective plant compounds called phytonutrients.
Many are carotenoids—the very antioxidants measured by the Prysm iO.
For example:
🟠 Orange foods
Carrots, sweet potatoes, squash and apricots provide beta-carotene.
🔴 Red foods
Tomatoes, watermelon and pink grapefruit are rich in lycopene.
🟢 Green foods
Spinach, kale and watercress provide lutein and zeaxanthin.
🟣 Purple foods
Blueberries, blackberries and cherries contain anthocyanins.
🌈 Every colour contributes something different, which is why variety is so important.
Protein – The Foundation of Repair
Protein isn't just for building muscle.
It's essential for producing collagen, repairing tissues and maintaining healthy skin.
Try to include a source of quality protein with every meal.
Examples include:
- Eggs
- Oily fish
- Chicken
- Steak
- Greek yoghurt
- Lentils
- Beans
- Tofu
- Nuts and seeds
Healthy ageing isn't about eating more.
It's about eating enough of the right building blocks.
Healthy Fats Build Healthy Skin
One of my favourite sayings is...
Healthy cell membranes create healthy skin.
Every skin cell is surrounded by a delicate membrane made largely from fats.
These membranes allow nutrients to enter and waste products to leave.
Healthy fats also support the skin barrier, helping reduce dryness, irritation and water loss.
Choose plenty of:
- Extra virgin olive oil
- Avocados
- Walnuts
- Flaxseed
- Chia seeds
- Oily fish rich in Omega-3
These are just as important for your skin as your moisturiser.
Stable Blood Sugar = Happier Skin
Another important principle is keeping blood sugar relatively stable.
Highly refined carbohydrates and sugary foods can cause rapid spikes in blood glucose.
Repeated spikes encourage inflammation and may contribute to collagen damage over time.
Instead, build meals around:
- Protein
- Fibre
- Healthy fats
- Whole grains
- Plenty of vegetables
This helps provide a steadier supply of energy while supporting healthier skin.
Choose More, Restrict Less
I don't believe in perfection.
Life is for living.
Instead of focusing on everything you can't eat...
Focus on adding more of the foods your body loves.
More vegetables.
More colour.
More healthy fats.
More protein.
More fibre.
If you eat well most of the time, the occasional slice of cake isn't going to undo all your hard work.
It's consistency that matters.
My Five Daily Habits for Healthier Skin
These are the simple habits I try to follow myself.
✔ Eat colourful vegetables every day.
✔ Include protein with every meal.
✔ Support my skin barrier with healthy fats.
✔ Take targeted nutritional supplements where appropriate.
✔ Measure my progress instead of guessing.
Because healthy ageing isn't about chasing perfection.
It's about making better choices, one day at a time.
Final Thoughts
One of the most exciting developments in health and nutrition is that we can finally begin to measure the impact of our lifestyle choices.
Beautiful skin has never been just about what we apply to the outside.
It's about how well we nourish ourselves from within.
Every healthy meal.
Every colourful vegetable.
Every good night's sleep.
Every walk.
Every supplement.
These small choices add up over time.
And now, thanks to technologies like the Nu Skin Prysm iO, we can begin to see how those choices are reflected inside the body—not just in how we feel, but in measurable antioxidant status too.
For me, that's the future of skincare.
Not simply treating skin...
But supporting healthier cells, healthier skin and healthier ageing from the inside out.
