Postbiotic Serum Concentrate
Rebalance skin’s healthy bacteria.
A microbiome-restoring serum concentrate for skin that has lost its balance. Formulated with 1.5% oat postbiotic and snow mushroom to calm redness, deepen hydration, and bring back the glow that over-treating has stripped away.

Does any of this sound like your skin?
Your skin suddenly flares up for no reason.
It feels tight after cleansing, even with the gentle one.
It breaks out around the jaw.
It stings now from products that never used to sting.
It looks dull in photos, no matter what you layer on it.
The problem isn’t on your skin. It’s living in your skin. Your microbiome is out of balance.
Why I made Aura
After 8 years of formulating, I kept seeing the same pattern. Women who were doing everything “right” but whose skin still felt off balance.
The missing piece wasn’t more actives. It was less interference. The skin’s microbiome, the trillions of good bacteria that live on your face, had been stripped away by over-cleansing, over-exfoliating, and over-treating.
So I built Aura around oat postbiotics. Postbiotics are what your skin’s good bacteria naturally produce when they’re thriving. They send signals that tell your skin to calm down, strengthen itself, and let the right microbes grow back.
In other words, oat postbiotics don’t fight your skin. They remind it how to be well.
Aura was built to put the balance back.

How Aura works
Your skin is home to trillions of microorganisms that form your microbiome. When they’re balanced, your skin looks calm, clear, and resilient. When they’re disrupted by harsh cleansers, over-exfoliation, stress or pollution, the result shows up as redness, dullness, breakouts, sensitivity, and premature ageing.
Aura works in three ways:
1. It restores the microbiome.
Our hero ingredient Lactobacillus Ferment is a bioactive postbiotic that signals your skin to rebalance its microbial community within days of consistent use.
2. It feeds the skin.
Oat (Avena Sativa) extract strengthens the barrier, reduces visible redness, and soothes reactive skin.
3. It deeply hydrates.
Snow Mushroom (Tremella Fuciformis) molecules are smaller than hyaluronic acid, which means they penetrate deeper and hold up to 500 times their weight in water. Skin looks plumper, calmer, and more resilient from the inside out.
What you’ll see
Within 7 days:
Reduced redness, visibly calmer skin, less reactivity to triggers.
Within 4 to 6 weeks:
Clearer, more even skin tone. Softer texture. Fewer breakouts. The lit-from-within glow that comes back when the barrier is finally allowed to rest.

FAQ
Can I use Aura with retinol or acids?
Yes, but let Aura go on first and alone for the first 2 to 4 weeks if your barrier is compromised. Once your skin feels calmer, you can layer other actives on top at night.
Will it work on acne-prone skin?
Yes. A balanced microbiome is one of the most under-addressed causes of adult acne. Many of our customers see fewer breakouts within 4 weeks.
Is it safe during pregnancy?
Yes. Aura contains no retinoids, no essential oils, and no ingredients contraindicated for pregnancy.
How long will one bottle last?
With twice-daily use, one 30ml bottle lasts approximately 8 to 10 weeks.
Can my teenager use it?
Yes. Aura is gentle enough for teenage skin dealing with hormonal breakouts and over-use of actives.
