Boreal Shield™

Built for the elements. Built like you.

Cold Climate Skin Protection

Winter changes what your skin needs. Boreal Shield™ meets them.

The Problem

Sub-zero conditions ask more of your skin.

≈0 g/m³ absolute humidity
at −20°C outdoors
5mo Of sustained barrier
stress each winter
113 Days per year below
freezing in Winnipeg

Wind, extreme cold, and near-zero humidity break down the skin barrier — accelerating moisture loss, depleting ceramides, and triggering the conditions that lead to sensitivity and premature ageing. We protect our skin from the sun all summer. Most of us leave it exposed all winter.

The Big Idea

It's time to treat winter
like we treat the sun.

Just as SPF protects against summer UV damage, Boreal Shield™ is engineered to defend your skin against the environmental stress of winter — wind exposure, sub-zero temperatures, and near-zero humidity that accelerates TEWL and depletes the skin barrier.

Prevention isn't just for summer. It's essential in the cold.

Proactive.
Not reactive.

01

Barrier Integrity

The stratum corneum lipid matrix — ceramides, cholesterol, free fatty acids — is the primary target. We replenish it at the 3:1:1 ceramide-dominant ratio associated with accelerated barrier recovery.

3:1:1 Ratio
02

TEWL Reduction

Transepidermal water loss accelerates dramatically in cold, dry air. Our occlusive layer is cold-stable — validated for film integrity at sub-zero temperatures, not just room-temperature lab conditions.

Cold-Stable
03

Environmental Stress

Wind chill, low humidity, and the indoor-outdoor temperature cycle compound barrier disruption. Formulas are stress-tested against all three simultaneously — not individual factors in isolation.

Field-Validated
04

Prevention First

The industry treats winter damage reactively. We apply the same logic as SPF — daily protection that matches how your skin actually experiences winter — sustained, not seasonal.

Daily Defence
The Products

Daily protection for
life in winter.

Shields against windburn and moisture loss. Supports the skin barrier in extreme cold. Supports long-term skin barrier integrity through sustained winter exposure.

This isn't just skincare. It's winter protection.

Proprietary — Winter Defense Protocol

The Winter
Defence Protocol.

Six measurable performance standards. Every formula is evaluated against each before it carries the Boreal Shield™ name. No exceptions.

Read The Protocol →
01

Northern Winter Design Brief

Every formula begins at −30°C, near-zero humidity, sustained wind — not a temperate baseline.

02

3:1:1 Ceramide-Dominant Ratio

Ceramides at the clinically established ratio for accelerated barrier recovery. Not trace concentrations.

03

Low-Humidity Humectant Efficacy

Humectants selected for performance at near-zero ambient humidity, not temperate conditions.

04

Cold-Stable Occlusive Performance

Film integrity validated at sub-zero temperatures. Performs in the field, not only in the lab.

05

No Unnecessary Irritation Risk

No fragrance. No ingredient whose only function is cosmetic appeal on an already-stressed barrier.

06

Prevention-First Purpose

Built for daily use before damage accumulates. A defence, not a repair.
