Transepidermal water loss (TEWL) is a natural process where water evaporates from the skin’s surface into the surrounding environment. This phenomenon plays a crucial role in maintaining skin hydration and overall health. However, excessive TEWL can lead to dry, dehydrated skin, causing discomfort and potentially exacerbating various skin conditions. In this blog post, we’ll delve into what exactly TEWL is, its causes, how to recognize it, and effective remedies to combat it, along with recommended products to help restore skin moisture balance.

What is transepidermal water loss (TEWL)?

Transepidermal water loss refers to the process of water evaporating from the skin’s outermost layer, the epidermis, into the atmosphere. This natural mechanism helps regulate body temperature and maintain hydration levels in the skin. However, factors such as environmental conditions, skin barrier function, and individual skin characteristics can influence the rate of TEWL.

Causes of TEWL

Several factors contribute to increased transepidermal water loss:

Environmental factors: Harsh weather conditions and changes, such as low humidity or cold temperatures, can accelerate TEWL by stripping the skin of its natural oils and moisture.

Impaired skin barrier: A compromised skin barrier, often due to excessive cleansing, exfoliation, or certain skin conditions like eczema or psoriasis, can lead to increased TEWL.

Age: As we age, our skin’s ability to retain moisture diminishes, making older individuals more prone to TEWL and dry skin.

Excessive UV exposure: Prolonged exposure to UV radiation can damage the skin’s protective barrier, leading to increased TEWL and dehydration.

Genetics: Some individuals naturally have a weaker skin barrier, making them more susceptible to TEWL and dryness.

How do you recognize TEWL?

Recognizing transepidermal water loss is crucial for implementing appropriate skincare strategies. Here are common signs of TEWL:

• Dry, flaky skin: Skin that feels rough or appears flaky is a common indicator of moisture loss.
• Tightness: A sensation of tightness or discomfort after washing or exposure to the environment.
• Itching and irritation: Increased itching or irritation, especially in areas prone to dryness.
• Dull appearance: Skin may appear dull or lackluster due to dehydration.
• Increased sensitivity: Heightened sensitivity to skincare products or environmental triggers.

How can TEWL be remedied?

Combatting transepidermal water loss involves a multi-faceted approach aimed at restoring and maintaining optimal skin hydration. Here are some effective remedies:

Hydrating cleansers: Opt for gentle, hydrating cleansers like the Amandola Milk Cleanser, formulated to cleanse the skin without stripping away its natural oils.

Moisturizers: Choose moisturizers rich in humectants, emollients, and occlusives to replenish lost moisture and strengthen the skin barrier. Products like the AquaPorin Hydrating Cream provide long-lasting hydration and promote water retention within the skin.

Serums: Incorporate serums like the Moisture on Demand serum into your skincare routine. Packed with hydrating ingredients, serums penetrate deeply into the skin to deliver intense hydration and combat TEWL.

Humidifiers: Use a humidifier indoors, especially during the winter months or in dry climates, to increase ambient humidity levels and reduce TEWL.

Protective clothing: Wear protective clothing, such as hats and scarves, to shield the skin from harsh weather conditions and minimize moisture loss.

Limit hot showers: Hot water can strip the skin of its natural oils, leading to increased TEWL. Opt for lukewarm showers and limit bathing time.

UV protection: Always wear sunscreen to protect the skin from UV damage, which can exacerbate TEWL and contribute to premature aging.
