Easy Ways to Prevent Transepidermal Water Loss!


If you’re experiencing dry, flaky, or dull skin, there’s a good chance it’s because of transepidermal water loss (or TEWL for short).

What is transepidermal water loss? This term refers to a simple physiological phenomenon: when water passively evaporates through the skin and into the air. This process is completely normal and inevitable. In fact, transepidermal water loss is happening to everyone throughout the entire day, although the process accelerates dramatically at night.

Why do I feel thirsty after waking up.

Your skin loses more water while you sleep than you are awake. Losing water from the skin is called trans epidermal water loss and it happens at the end of the day and into the night. Overnight when you don`t have a protective layer of natural oils on your skin you lose more water. If you often wake up in the morning with skin that feels dry or tight, you may be experiencing excessive transepidermal water loss (TEWL) overnight.

How Does Transepidermal Water Loss (TEWL) Impact the Skin?

Signs of skin dehydration and dryness will begin to appear when the rate of water loss from the epidermis is faster than the skin’s ability to rehydrate. If you’re suffering from excessive transepidermal water loss, you will begin to notice some or all of the key indicators of dehydrated and dry skin, including flaking, roughness, and increased visibility of fine lines. Feelings of tightness and discomfort are also signs of excessive transepidermal water loss.

What Causes Transepidermal Water Loss?

Some transepidermal water loss is inevitable due to the nature of the skin itself, but there are several factors that can exacerbate the process and lead to dry, dehydrated skin. These factors include being in low-humidity climates and employing aggressive skincare practices, such as over cleansing or using too many harsh ingredients.

How to Prevent Transepidermal Water Loss

Use a gentle cleanser 

Over cleansing (cleansing too often) and using a cleanser  formulated with strong natural ingredients are two factors that can cause the skin barrier to weaken over time, hindering it’s ability to lock in moisture effectively. As a result, swapping out your current product for a more gentle cleanser will help to keep the skin barrier operating optimally, and prevent the symptoms of TEWL.

We recommend using the DESERT BLISS LIGHT CAMEL MILK FOAM  twice a day, morning and night. This cleanser was developed  to cleanse and refresh the skin, without over-stripping the skin and compromising the natural skin barrier.

Use a hydrating camel milk cream for extra moisture

Adding a cream to your daily skincare routine is an opportunity to prevent transepidermal water loss by delivering powerful concentrations of hydrating ingredients to the skin after cleansing. Our DESERT BLISS Anti age luxury camel milk day cream SPF 50  contains a high concentration of Hyaluronic Acid, an ingredient that draws moisture into the skin, and helps the skin to retain that moisture. It also contains natural vitamins  to soothe dry skin.

Ingredients That Work to Avoid TEWL

Enriching your skincare regime with highly effective ingredients  that help to hydrate, support and maintain the skin barrier can help to reduce the signs of TEWL. Here are some key ingredients to look for in your skincare routine to help minimize symptoms:

CERAMIDES are natural lipids (oils) that are a key component of the skin. They make up over 50% of the skin and are an essential part of the skin barrier function in the stratum corneum, so continually applying them through skincare, plays an important role in protecting against transepidermal water loss. The CAMEL MILK RANGE DESERT BLISS  was developed due to natural camel milk rich in ceramides deliver three essential ceramides (1, 3 and 6-11) to the skin.

HYALURONIC ACID  is a humectant, which means it is powerful in retaining moisture in the skin. Look for cleansers, serums, or moisturisers with hyaluronic acid to build hydration into your skincare routine.

Niacinamide is a form of Vitamin B3 that can help soothe the skin and lead to an improvement in the skin’s ability to retain moisture.

Like hyaluronic acid, GLYCERIN is a powerful humectant. This ingredient captures water and keeps it in the skin, while also enhancing the penetration of other skincare ingredients. Look for glycerin in emollients, moisturisers and cleansers
