The One Habit I’d Prioritise for Skin Health Above All Else: Balancing Your Blood Sugar
If I had to choose one habit to focus on for clearer, calmer skin — it would be blood sugar regulation.
Not skincare.
Not supplements.
Not even eliminating foods.
Because when blood sugar is unstable, it creates a ripple effect through your hormones, inflammation levels, and nervous system — all of which directly impact your skin.
And this is something I see all the time in clinic.
Let’s break down why it matters, and how to actually start supporting it in a realistic way.
Why Blood Sugar Matters for Your Skin
Every time you eat, your blood sugar rises. This is completely normal.
But when meals are unbalanced, skipped, or eaten in a rushed or stressed state, blood sugar can spike quickly and then crash — and that’s where issues start to arise.
Blood sugar dysregulation can:
Increase inflammation in the body
Drive excess oil production
Impact androgen levels (linked to hormonal acne)
Increase cravings for sugar and refined carbs
Disrupt energy and mood
Over time, this creates the perfect internal environment for breakouts, congestion, and skin that just doesn’t seem to settle.
Balanced Meals: The Foundation
One of the simplest (and most effective) ways to support blood sugar is by building balanced meals.
This means combining:
Protein
Healthy fats
Fibre-rich carbohydrates
This combination helps slow down how quickly glucose enters the bloodstream, keeping levels more stable and preventing those sharp spikes and crashes.
A balanced plate might look like:
Eggs, avocado, and sourdough with sautéed greens
Chicken, rice, and roasted vegetables with olive oil
Greek yoghurt with nuts, seeds, and berries
It doesn’t need to be complicated — it just needs to be consistent.
Mindful Eating: The Missing Piece
You can be eating all the “right” foods, but if you’re eating in a stressed or distracted state, your body may not process that meal effectively.
When you’re rushing, working, or scrolling while eating, your body stays in a sympathetic (fight or flight) state — which isn’t ideal for digestion or blood sugar regulation.
Some simple shifts that can make a big difference:
Sitting down to eat (not eating on the go)
Slowing down your pace of eating
Chewing your food properly
Taking a few deep breaths before meals
These small habits help shift your body into a parasympathetic (rest and digest) state, allowing for better digestion and more stable blood sugar responses.
Stress and Blood Sugar: The Overlooked Link
Even if your diet is “perfect,” chronic stress can still disrupt blood sugar.
When you’re stressed, your body releases cortisol — which increases blood glucose levels to prepare you for action.
This means you can experience blood sugar spikes without even eating.
Over time, this can:
Increase insulin resistance
Drive inflammation
Worsen hormonal imbalances
Contribute to acne flare-ups
This is why managing stress isn’t just about feeling calmer — it’s a key part of supporting your skin.
Simple ways to support this include:
Breathwork
Gentle movement (like walking or Pilates)
Creating small moments of pause throughout your day
Setting boundaries around work and screen time
Sleep and Blood Sugar Regulation
Sleep is another piece that’s often overlooked when it comes to blood sugar.
Even one night of poor sleep can:
Reduce insulin sensitivity
Increase cravings for sugar and refined carbohydrates
Disrupt hunger hormones (ghrelin and leptin)
Increase cortisol levels
This makes it much harder to maintain stable blood sugar the following day — even if your meals are well balanced.
It becomes a cycle:
Poor sleep → blood sugar instability → cravings + energy dips → more instability
Which is why sleep and blood sugar always need to be addressed together.
Signs Your Blood Sugar May Be Affecting Your Skin
This doesn’t always show up in obvious ways.
Some signs I look for in clinic include:
Energy crashes (especially mid-afternoon)
Cravings for sugar or carbs
Feeling shaky, lightheaded, or irritable between meals
Needing caffeine to get through the day
Acne that flares around the jawline or lower face
These patterns can give us clues about what’s happening beneath the surface.
Where to Start
If this feels overwhelming, bring it back to the basics.
Start with:
Building balanced meals consistently
Eating regularly (not skipping meals)
Slowing down and being more present when eating
Supporting your nervous system
Prioritising sleep where possible
You don’t need to do everything perfectly — consistency matters far more than perfection here.
Supporting Your Skin From the Inside Out
Blood sugar regulation is one of the most powerful (and often underestimated) tools when it comes to improving skin.
But it’s rarely the only piece.
In clinic, I look at how your blood sugar, hormones, gut health, stress, and lifestyle are all interacting — so we can understand what’s driving your skin concerns and create a plan that actually works for your body.
