Hydration and Moisture Barrier Health

Hydration refers to the process of replenishing the body’s water content to maintain optimal hydration levels. Proper hydration is essential for overall health, as it supports various bodily functions, including digestion, circulation, temperature regulation, and skin health.

Moisture Barrier

The moisture barrier, also known as the skin barrier or lipid barrier, is the outermost layer of the skin composed of lipids, ceramides, and other substances that help retain moisture and protect against external aggressors. A healthy moisture barrier is vital for maintaining skin hydration, preventing water loss, and defending against environmental stressors.

Skin Hydration

Skin hydration refers to the water content within the skin cells and the skin’s ability to retain moisture. Adequate hydration is crucial for maintaining soft, supple skin, preventing dryness, and minimising the appearance of fine lines and wrinkles.

Hydrating Ingredients

Hydrating ingredients, such as hyaluronic acid, glycerin, and squalane, attract moisture to the skin and help lock it in, promoting hydration and improving skin elasticity and plumpness.


Humectants are ingredients that draw moisture from the environment or deeper layers of the skin into the upper layers, increasing hydration levels and improving skin texture. Common humectants include hyaluronic acid, glycerin, and honey.



Emollients are moisturising ingredients that smooth and soften the skin’s surface by filling in gaps between skin cells and creating a protective barrier to prevent moisture loss. Examples of emollients include shea butter, cocoa butter, and jojoba oil.


Occlusives are ingredients that form a barrier on the skin’s surface to seal in moisture and prevent water loss. They help strengthen the skin’s moisture barrier and maintain hydration levels. Common occlusives include petrolatum, lanolin, and mineral oil.

Barrier Repair

Barrier repair refers to the process of restoring and strengthening the skin’s moisture barrier to improve hydration, reduce sensitivity, and protect against environmental damage. This often involves using skincare products formulated with ceramides, fatty acids, and cholesterol.

Dry Skin

Dry skin lacks sufficient moisture and may appear rough, flaky, or tight. It can be caused by various factors, including genetics, environmental conditions, age, and skincare habits. Proper hydration and moisturization are essential for relieving dry skin and restoring its health and vitality.

Dehydrated Skin

Dehydrated skin lacks water content and may feel tight, dull, or rough. It can occur temporarily due to factors like weather, diet, or lifestyle habits or persistently due to impaired skin barrier function. Hydrating skincare products and lifestyle changes can help rehydrate and rejuvenate dehydrated skin.


Proper hydration and a healthy moisture barrier are essential for achieving and maintaining healthy, radiant skin. By incorporating hydrating skincare products, adopting healthy lifestyle habits, and protecting your skin from environmental aggressors, you can keep your skin plump, smooth, and youthful-looking. Remember to consult a medical professional before making any significant changes to your skincare routine, especially if you have sensitive or problematic skin.
