With the cold and dry weather, waking up with skin that feels dry and super tight is common. If that’s the case, you might be dealing with transepidermal water loss (TEWL) during sleep. TEWL refers to a physiological phenomenon that refers to the evaporation of water through the skin. Do not fret, as it is entirely normal and happens to every single one of us. The pace of the process can accelerate during the night.

Did you know that the average individual loses 300 to 400ml of water through the skin daily? It is super important to keep your skin hydrated, healthy, and happy. In today’s post, we will discuss what you can do to prevent it.

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

While we have established that TEWL is a natural process, let’s learn how it impacts your skin. The excessive water loss will result in many unwanted effects, such as dehydrated skin, faster aging, roughness, formation of fine lines, wrinkles, and dullness.

Preventing Transepidermal Water Loss

Following the right skincare tips is crucial to prevent transepidermal water loss. The key is to be consistent with your skincare routine. Here are a few steps to follow:

Opt for a Gentle Cleanser

Use a gentle cleansing option. Cleansing your skin with a product with strong, drying ingredients will weaken your skin’s barrier over time and hinder its ability to lock in moisture. Over-cleansing your face with an overly drying cleanser can lead to dry, cracked skin. A gentle cleanser will prevent TEWL. The choice of the cleanser is up to you. Just choose something that properly cleans the dirt and makeup without stripping your skill of essential oils and vital nutrients.

Opt for a Hydrating Serum

A serum is a significant part of the skincare routine. The serum penetrates the deep layers of the skin and hydrates it from within. We recommend trying Sérum TEWL. This product is formulated with an ultra-high concentration of lipid-replenishing, repairing, and protective oils. This ultimate combo of active ingredients restores your skin’s barrier and strengthens hydrolipidic film. It hydrates your skin profoundly and offers protection against external aggressors. If you are looking for intense nourishment and supreme comfort, look no further than this product.

Never Skip a Moisturizer

TEWL can happen on all areas of the skin, and it is necessary to moisturize your face and body thoroughly. Always use a moisturizer if your skin tends to feel dry. Apply it to your clean face twice a day post cleansing your skin. Remember your body and use a moisturizer immediately after stepping out of the shower.

Maintenance of a Healthy Skin Barrier

A healthy skin barrier will protect your skin against environmental stressors. It is essential for protecting it against common irritants. A weak skin barrier and TEWL go hand in hand. Make sure to use gentle, hydrating products that maintain your skin without stripping it of essential oils. The right cleanser, moisturizer, and serum will work wonders for you.

Invest in a Humidifier

Low-humidity environments can worsen transepidermal water loss and lead to dull, dry, and dehydrated skin. There is a way to prevent these problems. Investing in a humidifier will increase the moisture levels in the air and keep your skin hydrated and well-nourished. Use it in your office, home, or every place you spend most of your time in.

Do not Forget Your Hands and Feet

Our hands and feet are the driest parts of our body. This is because our hands and feet are continually exposed to the harsh elements of the environment. Moreover, repeatedly washing them results in extremely dry skin. Investing in a high-quality hand and foot cream that locks in moisture and thoroughly nourishes your skin is crucial.

Ingredients That Work Wonders for Preventing Transepidermal Water Loss

We haven’t focused too much on specific skincare products apart from the holy grail serum. The key is to choose products that have the right ingredients in them. Effective skincare products will hydrate, support, and maintain the barrier of your skin and ensure your skin is well nourished and moisturized. Always look out for these ingredients:


Ceramides are natural oils that form a vital part of the skin. Did you know that Ceramides make up 50% of the skin? The stratum corneum is essential for maintaining the skin barrier function. Make sure to continually apply products that have ceramides in them and protect them against transepidermal water loss.

Hyaluronic Acid

Hyaluronic acid is a humectant, meaning it works wonders to retain moisture. Look out for cleansers, serums, or moisturizers to lock in the hydration in your skin.


Niacinamide is a type of Vitamin B3 that soothes the skin and improves its ability to retain moisture. It also helps to improve skin texture.


Glycerin is another super powerful humectant that captures water and keeps it in the skin. It also enhances the penetration of other skincare ingredients. It is commonly found in moisturizers and lotions.

Final Takeaway

Transepidermal water loss is common but can lead to dehydrated and dull skin. The right products can help you in this regard and maintain the skin barrier while nourishing it from within. Always remember to be super consistent with your skincare routine to see true results.
