93% of women under prolonged stress showed facial inflammation

What this tells us about red, reactive skin in clinic...

I read a stat recently from a large-scale dermatological study looking at facial skin symptoms in women exposed to prolonged stress - and it really stopped me in my tracks.

The study assessed the facial skin of 12,529 women aged 14–65 under prolonged stress.

~93% showed early signs of inflammation (mild increases in sebum production, redness, enlarged pores, moderate blackheads and localised rashes)

with 7% exhibiting more pronounced inflammatory changes

That’s a pretty clear conclusion: stress plays a significant role in what we’re seeing in clinic.

And while it’s easy (and common) to say “it’s just stress”, I’ve found that to truly help our clients, and ourselves, we need to go a step deeper.

Because when clients understand how stress is influencing their skin, not only does it guide more effective interventions, it also helps them accept what’s happening, rather than feeling frustrated, confused or like their skin is “failing” and their skin is something they need to fight to fix….cue more stress - redness - inflammation.

So if you’re regularly supporting red, reactive, sensitised or inflamed skins in clinic, keep reading. Below is a clear, practical round-up of the key mechanisms behind the stress–skin connection - and I’ll also share how I’ll be unpacking these in more depth inside my upcoming Calm Skin mini series.

It’s planned for that quieter Christmas / New Year lull, when let’s face it, many of us find ourselves doing a bit more scrolling than usual….so why not use some of that time for bite-sized CPD that helps you step back into clinic in 2026 feeling clearer, calmer and more confident explaining what’s really going on with your clients’ skin.

Let’s get into it…

The skin and brain are in constant conversation

Your skin and your brain come from the same embryonic layer (the ectoderm), which is why they’re so deeply connected. Think of them as twins who always feel connected 👯‍♀️

They communicate via hormones, neurotransmitters and neuropeptides (chemical messengers that influence immunity, inflammation, barrier function and pigment production).

And here’s the key reframe:

Skin is not just a passive victim of stress. It’s an active stress organ

🫳🎤

Yep that’s right, the skin can make it’s own stress hormones locally. It doesn’t just respond to what’s happening in the brain - the skin actively participates.

A quick, simple look at the stress pathway (HPA axis)

You’ll hear the term HPA a lot, so let’s demystify it.

The HPA axis (hypothalamus–pituitary–adrenal axis) is basically your body’s stress relay system:

• The brain senses stress and releases CRH
• CRH tells the pituitary to release ACTH
• ACTH tells the adrenal glands to release cortisol

Cortisol’s job is to help us cope short-term: raise blood sugar, sharpen focus, mobilise energy. As a short term measure it actually has an anti-inflammatory role within the body.

But when stress becomes chronic, be it emotional, psychological, lifestyle-driven, cortisol stays elevated for too long. And that’s where skin starts to struggle.

Even more interesting?

The skin has its own mini HPA-like system.

It can produce CRH, ACTH and cortisol locally, right there in the tissue.

Which means stressed skin can stay stressed - even when the original trigger has passed 🫠

Three key ways stress shows up on the skin

1. Barrier disruption
Chronic stress and cortisol reduce lipid production, slow repair, and increase transepidermal water loss. Think of cortisol like a manager who keeps cancelling maintenance work - eventually the building starts to leak.

This is why stressed skin feels tight, reactive, stingy and “no product seems to suit it”.

2. Inflammation & immune confusion
Stress increases neurogenic inflammation (nerve-driven inflammation) and alters immune signalling in the skin. This can worsen acne, eczema, psoriasis, rosacea and delayed healing.

And yes - stressing about the skin often makes it worse. A vicious loop I’m sure you’ve seen many times 🤯

3. Pigmentation & redness
Stress hormones can stimulate melanocytes and increase vascular reactivity. Translation: more redness, flushing and pigment - especially in already sensitised skin.

This is why flare-ups often coincide with emotional or psychological load, not just product changes.

Why this matters for you as a skin therapist focused on long term skin health, not short term fixes

Large clinical studies show that chronic psychosocial stress is strongly associated with sensitive and inflammatory skin patterns - particularly in women.

So when we ignore stress, we’re often missing a major driver of what we see on the surface.

Understanding this gives you language, confidence and compassion in the consultation. It helps clients feel understood - not blamed, the skin is literally making its own stress hormones! - and opens the door to more realistic expectations and better outcomes.

What’s coming next

During that quiet Christmas–New Year lull, I’ll be sending out a short mini learning series where we’ll go deeper into these mechanisms…

How stress triggers and sustains inflammatory skin conditions
Why leaky skin is not just a topical thing
The pigmentation, melanogenesis, stress cycle
How to explain the stress–skin link to clients without overwhelming them

'Cos my my goal is simple :

To help you feel confident, grounded and clear when explaining what’s really going on behind your clients’ flares - and how to support their skin more effectively.

More soon 💛

In the meantime, I hope you are looking forward to a joy and rest filled break and Merry Christmas!

Lots of love,
