Identify and Repair Your Broken Skin Barrier

Flaky or tight skin, stinging from previously tolerated products, new breakouts, rashes, or inflammation from new products are all symptoms of a compromised skin barrier!

WHAT IS THE SKIN BARRIER

The skin barrier is the outermost layer of skin. It is composed of flattened skin cells embedded in a matrix of lipids (ceramides, cholesterol, and fatty acids). Its primary function is to prevent water loss from underlying layers and block external irritants such as pollutants, allergens, and microbes.

WHAT HAPPENS WHEN THE SKIN BARRIER IS DAMAGED

Disruption of the skin barrier results in a breakdown of its protective and regulatory functions.

1. Elevated Water Loss: when the skin barrier is damaged, its ability to retain moisture is compromised, causing increased water loss through the skin's surface. This is known as transepidermal water loss (TEWL). Clinical research confirms that TEWL rises significantly in barrier-damaged skin (Fluhr et al., 2006, Experimental Dermatology).

2. Microbial Imbalance: the skin microbiome is composed of beneficial microorganisms that become destabilized when the barrier is impaired. This shift is associated with heightened inflammation and conditions such as acne and eczema (Byrd et al., 2018, Trends in Microbiology).

3. Inflammatory Response and Reactivity: barrier disruption stimulates the release of inflammatory cytokines, increasing skin sensitivity. This can cause discomfort even when using mild or previously tolerated skincare products. 

COMMON CAUSES OF BARRIER BREAKDOWN

Excessive exfoliation or frequent use of strong actives, cleansers containing ingredients that strip the skin (e.g. drying alcohols), frangrance and essential oils, enviornmental stressors (e.g. dry air, cold temperature, prolonged exposure to hot water), medical skin conditions (e.g. eczema, rosacea, dermatitis).

HOW TO REPAIR A BROKEN SKIN BARRIER

Restoring the skin barrier is not about doing more, it is about doing less and doing it right.

1. Lipid Replenishment: Ceramides NP, AP, and EOP are bio-identical lipids that reinforce the skin’s structural matrix. Clinical studies demonstrate that ceramide-rich formulations reduce TEWL and enhance barrier recovery (Draelos, 2018, Journal of Clinical and Aesthetic Dermatology).

2. Hydration: Ingredients like glycerin and sodium hyaluronate attract and retain moisture within the skin. Glycerin, in particular, has been shown to significantly improve hydration levels in dry, damaged skin (Lodén et al., 2003, Journal of European Academy of Dermatology and Venereology).

3. Anti-Inflammatory Support: colloidal oatmeal and beta-glucan help reduce redness and soothe inflamed skin. Clinical studies show they are effective in calming irritation and supporting skin recovery (Lynde et al., 2016, Journal of Drugs in Dermatology).

4. Moisture Retention: squalene and dimethicone form a protective barrier on the skin to prevent water loss, without clogging pores. Clinical research supports its effectiveness in reducing moisture-loss and supporting barrier repair (Lodén et al., 2003, Journal of European Academy of Dermatology and Venereology).

FORMULATION CONSIDERATIONS

Products designed to support barrier repair should exclude common irritants such as added fragrance, drying alcohols, and essential oils. Formulations should prioritize clinically supported actives at barrier-safe concentrations.

A damaged skin barrier is not a superficial issue. It is a disruption of the skin’s essential biological functions. Addressing it requires restraint, ingredient precision, and a focus on repair.

The Irritated. Face & Body Serum is formulated in accordance with these principles. It contains ceramides, humectants, soothing agents, and occlusives, without added fragrance, alcohol, or essential oils. Each ingredient was selected based on clinical research to support hydration, reduce sensitivity, and strengthen the skin barrier.
