Skin School: Trans-Epidermal Water Loss
If not, this is a term you will want to learn and get your skin on top of as it is essential to keeping skin hydrated, firm and primed. Trans-epidermal water loss (TEWL) is the process by which water evaporates from the skin's surface and is lost to the surrounding environment.
TEWL occurs when the skin barrier is compromised, allowing moisture to escape from the deeper layers of the skin.
When TEWL is high, it can lead to dehydration and dryness of the skin. This can make the skin look dull and rough and can exacerbate the appearance of fine lines and wrinkles. High TEWL can also make the skin more susceptible to damage from environmental stressors such as UV radiation and pollution.
So you can see, most of the time when our skin is look lacklustre and wrinkled - it is the effect of trans-epidermal water loss.

What can cause TEWL on the skin?
- Environmental factors: Cold and dry weather, low humidity, and wind can all increase TEWL.
- Skin disorders: Skin conditions such as eczema, psoriasis, and rosacea can disrupt the skin barrier and increase TEWL.
- Aging: As we age, our skin becomes thinner and loses its natural oils, which can weaken the skin barrier and increase TEWL.
- Harsh skincare products: Skincare products that contain harsh ingredients or that are not pH-balanced can disrupt the skin barrier and increase TEWL.
