What is Trans Epidermal Water Loss?
Trans epidermal water loss, also known as TEWL, is a very real thing that many people experience. It’s the process that causes moisture to leave the body through the skin’s surface. Some people have higher levels of TEWL than others because their skin doesn’t produce enough natural oils or they live in an environment with low humidity.
Trans epidermal water loss can occur at any time in life but it often occurs during periods of illness, such as a common cold or flu, or as we age. It can be caused by taking certain medications, like those prescribed for acne and psoriasis treatment. And winter weather can also cause increased trans epidermal water loss due to the dryness and chilly climate.
The good news is that you don’t have to let trans epidermal water loss disrupt your life and your skin! There are plenty of ways to manage and prevent it:
+ See your dermatologist if you suspect you have high levels of TEWL – he/she may prescribe a topical ointment or medication to help keep your skin hydrated
+ Use humidifiers and vaporizers in your home during winter months
+ Don’t use harsh soaps or harsh cleanser on your face or body – they will
+ Wear a proper SPF protection when you are outdoors. Modern moisturizer commonly formulated with SPF within it so that it can provide double function, hydrating and sunscreen for your skin.
How can you prevent or manage TEWL?
TEWL is a natural process. The body releases water through the skin’s surface to keep it hydrated and help fight any bacteria that may be on the skin. With TEWL, moisture leaves the body through the skin’s surface.
TEWL can be caused by numerous things, including weather, humidity levels, occupation or hobbies, and even injury or illness. There are many ways to prevent or manage TEWL. The first thing you should do is make sure you stay hydrated throughout the day to avoid dehydration. You can also try taking a shower or bath before getting dressed to allow your skin time to rehydrate after sweating due to heat or high humidity levels.
Another way to manage this type of dry skin is by using moisturizer often, especially when you’re feeling more sensitive than usual because of lower humidity levels in your environment. You should wear synthetic fabrics that are less likely to retain water as well as air out your house more often if it’s humid outside—this will help reduce TEWL because there will be less water vapor in the air for your body to release through its pores.
Trans Epidermal Water Loss (TEWL) is a measure of how much water evaporates from your body’s surface, through the epidermis, in a given time. It is an important measure of skin health. It can be measured in terms of relative humidity, which is the percentage of water in the air outside the body to that inside the body. A humidity gradient exists between these two points.
There are many factors that can affect the rate of water loss, including age, environment, genetics, occupation, diet. It is possible to prevent or manage TEWL with lifestyle changes and topical moisturizers.
