The Face Barrier Serum in macro

Skin that works the way it’s meant to

Your skin was built to protect, repair and renew itself, it just needs the right support.

IMNX+® supports your skin’s barrier and microbiome simultaneously, to power your skin’s natural defences. Clinically proven across five independent studies.

Skin architecture

Four systems, working as one.

They don't work in isolation. Disrupt one, and the rest are affected.

  1. Keep water in

    Skin Barrier

    The outermost epidermis is built from cells held in a lipid matrix. Together they limit water loss and help keep everyday irritants out.

    An intact skin barrier gives the other skin systems a stable place to work.

  2. Maintain balance

    Microbiome

    Bacteria, fungi and other microorganisms form a varied ecosystem on the skin surface. Its composition is linked with skin barrier function and surface pH.

    The microbiome and skin barrier continually shape one another.

  3. Read the environment

    Immune Defence

    Resident immune cells and skin cells monitor contact at the surface. Their response is influenced by signals from both the skin barrier and microbiome.

    Balanced signalling helps skin respond appropriately to its environment.

  4. Rebuild continuously

    Cellular Renewal

    New epidermal cells form below and move towards the surface, replacing cells that are naturally shed. This cycle supports the skin barrier over time.

    Renewal completes the loop by continually rebuilding the surface.

Patent pendingFour years in developmentSpecialist British chemists

Three pathways. One considered formula.

IMNX+® is powered by tribiotics, for complete skin health support. It is formulated to work in sync with the skin’s natural defences and processes.

Prebiotics

Provide a food source used by selected members of the skin microbiome.

Inulin, Alpha-Glucan Oligosaccharide and Avena Sativa (Oat) Kernel Extract

Probiotics

Fermentation-derived probiotic actives included to support a balanced skin environment.

Lactobacillus and Lactococcus Ferment Lysates

Postbiotics

Fermentation-derived materials complement the formula's skin barrier and hydration ingredients.

Ferment lysates and filtrates

Independent clinical testing

What changed in 28 days.

The finished formula was assessed using instrumental measurements, dermatological oversight and a separate four-phase microbiome evaluation.

Participants aged 31–58, men and women · Twice-daily use

Skin barrier function

Significantly improved

Vapour metre readings compared each participant's treated and untreated sites.

Transepidermal water loss

Significantly reduced

Instrumental vapour metre assessment under dermatological oversight.

Visible redness

Reduced

Colourimetry isolated the erythema signal from melanin for an objective reading.

Fine lines and wrinkles

Significantly reduced

SELS® clinical imaging measured changes in the skin surface.

Microbiome friendly

9.5/10

A separate four-phase independent assessment by Kind to Biome.

Certification context

Irritation and sensitivity

Zero irritation reactions.

A separate 50-person, 42-day Human Repeat Insult Patch Test on a sensitive and eczema-prone panel recorded zero irritation reactions.
