SCIENCE & BARRIER

UNDERSTAND YOUR BARRIER

The skin barrier locks in moisture and provides the first line of defense against external stressors. Every formula is designed to support it. Here, we explain how it works, what challenges it and the evidence behind our approach.

SKIN BARRIER

YOUR BARRIER IS HOW
YOUR SKIN PROTECTS ITSELF

Transparent gel blocks that resemble brick and mortar structure

BRICKS

Corneocytes are the building blocks of the outermost layer of skin.

MORTAR

Ceramide, cholesterol and fatty acids hold the bricks together.

TEWL

Transepidermal water loss. A low TEWL is indicative of a strong barrier.

KNOW YOUR BARRIER >

WHAT STRESSES YOUR BARRIER

The barrier is a self-renewing structure; But when the load exceeds the recovery rate, water loss increases and the skin feels tight and sensitive.

HARSH CLEANSING

Sulfate-based, heavily foaming cleansers and hot water can strip the skin’s surface lipids.

TOO MANY ACTIVES

Layering strong actives in the same routine can leave the barrier little time to recover.

SUN

UV rays increase the daily stress load of the skin and fatigue its support structures in the long term.

ENVIRONMENT

Dry indoor air, wind and cold accelerate water loss.

TIME

Over the years, the skin's own lipid and moisture production slows down.

OUR APPROACH

FIVE FUNCTIONS, ONE SYSTEM

Barrier support takes complementary actions, not a single active ingredient. Our six products share these roles throughout your routine.

  1. 01

    REPLENISH

    Ceramide NP and botanical oils help replenish a weakened lipid matrix.

    Ceramide NP · botanical oil blend

  2. 02

    STRENGTHEN

    Niacinamide strengthens the barrier from the inside by supporting the skin's own ceramide synthesis.

    Niacinamide

  3. 03

    RETAIN MOISTURE

    Humectants and NMF-like ingredients retain water in the upper layers of the skin.

    Hyaluronic acid · Sodium PCA · amino acids

  4. 04

    SOOTHE

    Soothing ingredients support comfort and tolerance.

    Centella · panthenol · allantoin · bisabolol

  5. 05

    PROTECT

    The photostable, broad-spectrum filter system completes the morning routine.

    DHHB · BEMT · Ethylhexyl Triazone

FORMULATED FOR RESULTS

THE SAME FOUNDATION IN EVERY PRODUCT

  1. 01

    NIACINAMIDE

    Supports ceramide synthesis and a more even-looking skin tone.

  2. 02

    CERAMIDE NP

    Helps replenish the barrier’s lipid matrix.

  3. 03

    PREBIOTIC FOS

    It supports the balanced environment of the microbiome.

  4. 04

    BOTANICAL OILS

    It nourishes and softens with linoleic acid and GLA.

  5. 05

    HYALURONIC ACID

    Supports hydrated, plump-looking skin.

OUR LANGUAGE OF EVIDENCE

WHAT IS BEHIND OUR WORDS?

We use words such as ‘supports’ and ‘helps’ because cosmetics do not treat skin conditions; they work alongside the skin’s own functions.

We publish numerical results, including SPF ratings, only when supported by testing on the finished product. We also make the evidence level for each ingredient clear.

WELL ESTABLISHED
An ingredient whose effects have long been understood and are widely accepted in the scientific literature.
WELL SUPPORTED
A widely used ingredient supported by controlled studies.
EMERGING RESEARCH
Area under ongoing research; That's why we keep our claims cautious.
