We all know that drinking enough water is essential for our overall health, but did you know that your skin has its own internal irrigation system? This intricate network of microscopic channels, called aquaporins, is responsible for transporting water between skin cells and maintaining optimal hydration from within. Understanding the role of aquaporins is the key to unlocking a new level of skin hydration.
Aquaporins are proteins that form channels through the cell membrane, allowing water to flow in and out of the cell. They were discovered in the early 1990s, a breakthrough that earned the 2003 Nobel Prize in Chemistry. There are at least 13 different types of aquaporins in the human body, but the most important one for skin health is aquaporin-3 (AQP3) [1].
The Role of AQP3 in Skin Hydration
AQP3 is found in the basal layer of the epidermis, the deepest layer of the skin’s outer surface. It plays a crucial role in transporting water from the dermis, the layer of skin below the epidermis, up to the stratum corneum, the outermost layer of the skin. This process is essential for maintaining the skin’s natural moisture balance and for ensuring that the skin barrier is able to function effectively [2].
Functions of AQP3 in the Skin:
| Function | Description |
|---|---|
| Water Transport | AQP3 facilitates the transport of water from the dermis to the epidermis, ensuring that the skin remains hydrated from within. |
| Glycerol Transport | In addition to water, AQP3 also transports glycerol, a natural humectant that helps to attract and retain moisture in the skin. |
| Barrier Function | By ensuring that the stratum corneum is properly hydrated, AQP3 helps to support a healthy skin barrier. |
Stimulating Your Skin’s Inner Waterways
As we age, the expression of AQP3 in the skin can decline, which can lead to dehydration and a compromised skin barrier. However, there are ways to stimulate the production of AQP3 and to support the skin’s natural hydration processes.
Certain skincare ingredients, such as gluco-glycerol, have been shown to stimulate the expression of AQP3 in the skin [3]. By incorporating these ingredients into your skincare ritual, you can help to boost your skin’s internal irrigation system and to achieve a complexion that is visibly more hydrated, plump, and radiant.
At Truff’elle, our bio-fermented truffle extract has been shown to modulate the gene expression of aquaporins, effectively “turning on” the skin’s internal hydration channels. This is just one of the many ways that our formulations work in harmony with your skin’s natural processes to restore its youthful vitality.
