Help Customers Minimize Transepidermal Water Loss


 June 15, 2019

Dry, dehydrated skin is a common problem for both women and men, especially if they live in a dry climate or extreme temperatures. Consumers are constantly looking for ways to protect their skin from external natural factors and ensure their skin stays looking youthful and hydrated. Beauty and skincare brands need to help them minimize transepidermal water loss in order to stave off these skin issues.

What is Transepidermal Water Loss (TEWL or TWL)?

Transepidermal water loss, or TEWL for short, is a term commonly used to characterize skin barrier function.

TEWL occurs when water passes from the dermis through the epidermis and evaporates from the skin’s surface. When water evaporates faster than the body is able to replace it, skin becomes dehydrated. This can lead to rough, itchy or irritated skin that can appear more aged, as fine lines and wrinkles are accentuated.

Although TEWL is a natural process for skin regulations, certain things, such as seasonal changes, injury, UV light, low-humidity and topically applied personal care products that dry out the skin can all impact transepidermal water loss.

Optimizing moisture levels, therefore, is a key component to helping your customers maintain skin health and ensure a youthful appearance.

Hydrating Ingredients

Three main categories of ingredients are found in effective moisturizers: humectants, occlusives and emollients.

  • Humectants — Substances that naturally attract water. They pull water from the environment to the skin when used in humid environments, and in dry conditions, humectants draw moisture from the dermis to the epidermis. This allows the skin to improve its ability to hydrate itself over time.

Examples: Manuka honey and aloe vera

  • Occlusive agents —  Hydrophobic substances that naturally act as a barrier so water cannot pass. They create a hydrophobic barrier over the skin, “contribute to the matrix between corneocytes” and have the most pronounced effect when applied to slightly dampened skin. Limiting factors with many occlusives include potential odors, allergenicity and greasy feel.

Example: Beeswax

  • Emollients  Substances that help keep the skin smooth, flexible and lubricated. They not only hydrate and improve the skin softness and smoothness but also play a large role in contributing to consumer satisfaction.

Example: Jojoba seed oil


Each ingredient plays a significant role in the skin’s architecture, while reducing transepidermal water loss.
