MICROBIOME 101 WITH SÁSTA SKIN HEALTH
Each year on June 27th, we celebrate World Microbiome Day. This year, we’re turning our
attention to something you can’t see, but your skin feels every day: The microbiome – the
invisible ecosystem of bacteria living on and within us is finally having a well-deserved moment
of appreciation. And the 2025 theme ‘Microbiome 101 -Everything You Need to Know’ couldn’t
be more timely!
It’s no longer just about gut health, your skin has its own living, breathing community of
microbes. When this delicate balance is maintained, your skin thrives: healing faster, resisting
breakouts, sensitivity and aging more gracefully. But when the balance is disrupted by stress,
pollution, harsh cleansers or over-exfoliation, the effects are all too familiar: inflammation,
acne, irritation and redness.
One Irish brand is bringing skin health back to basics, powered by cutting-edge science. Sásta
Skin Health, founded by Michelle McDonald, is all about feeding that good bacteria so skin can
do what it was designed to: protect, repair and thrive.
Sásta’s hero product, the Microbiome Booster Serum (RRP €45), isn’t just
skincare, it’s skin healthcare. This daily topical supplement supports the skin
barrier, soothes inflammation and calms sensitivity. Developed over three
years this isn’t fast beauty – it’s precision skincare, grounded in science and
sustainability.
The serum is packed with microbiome-nurturing ingredients: Ectoin to protect,
Lactobacillus Ferment Lysate to restore & balance, and Cottonbloom Extract
to Nourish.
With an advanced blend of prebiotics and postbiotics it’s no surprise the serum is
MyMicrobiome Certified – meaning it’s been independently proven to support the delicate
ecosystem of your skin.
“As someone who’s spent over 25 years in the beauty industry and also as a mother, I’ve seen
first-hand how disconnected we’ve become from what our skin really needs.
I created Sásta to bring the focus back to skin health – to treat the skin like the living organ it is, starting with the
microbiome. We don’t need complicated routines; we need smarter, science-led solutions that work with the body, not against it. That’s what Sásta is about – creating calm, resilient skin by supporting the microbes that’re already working for us.”— Michelle McDonald, Founder of Sásta Skin Health
Formulated and made in Ireland, Sásta is 100% Irish-owned, Guaranteed Irish and committed to
small-batch production, ensuring high quality and a low carbon footprint. Every step, from
formulation to packaging, is crafted with sustainability, efficacy and long-term wellness in mind.
Sásta means “happy” / “Contented” in Irish – and that’s the goal. Happy skin, happy planet. So
this World Microbiome Day, take a moment to rethink what you’re feeding your skin. Because
sometimes the smallest organisms are doing the most important work.
