WHO IT’S FOR?

BUFFÈRE™ was developed around a simple idea: when the skin barrier is compromised, it often needs more than a heavier moisturizer. It needs water retention, lipid replenishment, and protection from environmental stress working together.

Part of our formulation philosophy is to design for the extremes; considering people with exceptionally dry, reactive, eczema-prone skin, as well as those who may need or prefer to avoid ingredients commonly found even in sensitive-skin formulas.

For that reason, BUFFÈRE™ is intentionally formulated without nut butters such as shea or cupuaçu, an important consideration for those who prefer to avoid nut-derived ingredients. It is also grain-free, providing an alternative for people avoiding grain-derived ingredients such as colloidal oatmeal, despite oatmeal’s well-established place in sensitive-skin and barrier care.

We also leave out ragweed-family botanicals such as chamomile, as well as traditional fatty-alcohol structuring ingredients. BUFFÈRE™ is additionally hyaluronic acid-free, niacinamide-free, tocopherol-free, and soy-free.

Rather than simply removing ingredients, we built an alternative barrier system. At its heart is 7% ectoin, paired with 8.10% liposomal allantoin, more than 5% panthenol, 5.55% jojoba phospholipids, ceramides NP, AP and EOP, cholesterol, sodium PCA, and saccharide isomerate. Together, these ingredients address water retention, soothing support, environmental stress, and lipid replenishment through multiple complementary pathways.

Use  BUFFÈRE™ when skin feels very dry, tight, reactive, depleted, or over-treated, and on recovery nights between stronger treatments such as acids and retinoids. It can also be incorporated as additional barrier support around hair and skin professional treatments with your provider’s guidance.

IDEAL FOR

  • Dry, dehydrated, or barrier-compromised skin
  • Sensitive, reactive, or uncomfortable skin
  • Skin using retinoids, acids, or intensive actives
  • Skin exposed to environmental stressors
  • Sensitive scalps following color, chemical treatments, or topical minoxidil use

BUFFÈRE™ is a concentrated barrier-support formula developed to provide hydration and support normal skin and scalp barrier function.

With 7% ectoin, ceramides, jojoba phospholipids, panthenol, allantoin, Sodium PCA, saccharide isomerate, and aloe, BUFFÈRE™ helps attract and retain moisture while supporting dry, sensitive, and barrier-compromised skin and scalp.

The lightweight formula can be used daily or alongside retinoids and exfoliating acids, and on sensitive scalps following color, chemical treatments, or topical minoxidil use, when additional hydration and barrier support are needed.

Barrier Support
7% ectoin, jojoba phospholipids, ceramides, cholesterol, and panthenol support skin and scalp barrier function and comfort.

Dehydration
Sodium PCA, saccharide isomerate, aloe vera, glycerin, and other humectants help attract and retain water to support skin and scalp hydration.

Environmental Stress
Ectoin has been studied for its protective and stabilizing properties under environmental stress conditions. BUFFÈRE™ contains 7% ectoin alongside hydrating and barrier-supportive ingredients to support skin and scalp exposed to environmental and routine-related stressors.

Retinoids, minoxidil, exfoliating acids, frequent cleansing, chemical treatments, and environmental exposure can contribute to dryness, irritation, and changes in skin and scalp barrier function.


BUFFÈRE™ combines 7% ectoin with ceramides, cholesterol, jojoba phospholipids, panthenol, Sodium PCA, saccharide isomerate, and other humectants to support barrier function, hydration, and skin and scalp comfort.


The formula can be used daily on the skin or scalp, or alongside routines containing retinoids, exfoliating acids, and topical minoxidil when additional hydration and barrier support are needed.

BUFFÈRE™ combines ectoin, barrier-supportive lipids, humectants, and soothing ingredients selected for dry, sensitive, and barrier-compromised skin.

7% Ectoin
Ectoin is a naturally occurring compatible solute studied for its hydrating, stabilizing, and protective properties. BUFFÈRE™ contains ectoin at 7%, a concentration also found in European CE-marked medical-device formulations developed for dermatitis and compromised skin barriers.

Jojoba Phospholipids
Provide emollient and skin-conditioning properties while complementing the formula’s lipid components.

Ceramides + Cholesterol
Ceramides, cholesterol, phytosphingosine, and phospholipids support the skin’s lipid barrier and help reduce moisture loss.

Allantoin + Panthenol
Liposomal allantoin, panthenol, aloe vera, and glycerin provide hydration and help support skin comfort.

Saccharide Isomerate + Sodium PCA
Saccharide isomerate and Sodium PCA are humectants that help attract and retain water in the stratum corneum.

Intentionally Formulated Without
Colloidal oatmeal, chamomile, calendula, niacinamide, tocopherol, hyaluronic acid, soy-derived ingredients, nut-derived oils, or grain-derived ingredients.

BUFFÈRE™ takes its name from the French word barrière, meaning barrier, and buffer—reflecting its role in supporting skin and scalp through dryness, sensitivity, and intensive routines.

The concept began as a kind of “skin diet.” Many products formulated for baby, sensitive, and eczema-prone skin rely on the same familiar ingredient families. While generally well tolerated, even commonly used sensitive-skin ingredients can cause contact reactions in some individuals.

We took a different approach: remove some of the conventional choices and rebuild the formula around alternative pathways to hydration, soothing, and barrier support. Instead of colloidal oatmeal, traditional soothing botanicals, nut-derived butters, and a conventional fatty-alcohol-heavy structuring system, BUFFÈRE™ uses 7% ectoin, liposomal allantoin, mango butter, jojoba phospholipids, ceramides, cholesterol, and a lamellar emulsifier system.

The result is a deliberately edited barrier formula designed to support hydration, comfort, and resilience without simply repeating the sensitive-skin formulation playbook.

BUFFÈRE™ is designed for daily barrier support, including alongside active skincare when additional hydration and comfort are needed.

7% Ectoin
A substantial concentration of ectoin, an ingredient studied for its hydrating and protective properties. Concentrations of 7% ectoin are also used in certain European CE-marked medical-device formulations for compromised skin.

Skin + Scalp
Formulated for use on dry or sensitive areas of both the skin and scalp.

Jojoba Phospholipids
Jojoba-derived phospholipids provide emollient and skin-conditioning properties and complement the formula’s ceramides and cholesterol.

Saccharide Isomerate + Sodium PCA
Two humectants that help attract and retain water to support lightweight hydration and skin comfort.

Skin: Apply alone as a lightweight hydrating formula, use daily as part of your morning routine, or layer with retinoids and exfoliating acids when additional hydration and barrier support are needed. It can be worn alone or layered beneath your moisturizer, facial oil, BASTINA  or LAMELLARE when your skin needs additional support.
Scalp: Apply a thin layer directly to areas of dry or sensitive scalp as needed, including alongside topical minoxidil routines or following color and chemical treatments when additional hydration and barrier support are desired.
