We all try to drink enough water. Most of us carry the bottle, track the ounces, and check the box by the end of the day. Here's something that often goes unnoticed: the body expels water at almost the same rate that it is absorbed.

If your skin still feels tight or looks dull by mid-afternoon even when you drink enough water, there may be another underlying cause at play.

The Science of Staying Hydrated

Skin loses water through a process called transepidermal water loss, or TEWL. TEWL is the measure of how much moisture escapes through the surface of the skin.

This is a constant, often unnoticed occurrence. The process of moisture moving from your skin into the drier surrounding air is driven by the difference in humidity levels between these two areas. Heated rooms pull moisture out; air conditioning pulls it out too; even a cool breeze pulls it out.

This phenomenon has little to do with how much water you drink, though staying hydrated remains important. Plain water itself is also not a long-lasting solution. Free water molecules are small and highly mobile, and they escape through transepidermal water loss (TEWL) with ease. To maintain moisture, it is essential to have a structure that can capture moisture, just like a sponge.

Nature's Molecular Sponge

When it comes to the property of retaining water, hyaluronic acid (HA) is the first substance that comes to mind. It is the most widely used humectant in skincare products. In nature, however, Tremella exhibits a remarkably similar performance.

These two substances share many similarities. Both are hydrophilic polysaccharides with strong moisture retention capacity. In fact, each of them can bind many times its own weight in water. They rely on a dense hydrogen bond network to attract and lock free water, turning loose liquid into a soft, stable gel that does not evaporate easily.

The source is where the two differ. Most hyaluronic acid (HA) exists as a single isolated compound produced in the laboratory via microbial fermentation. In contrast, Tremella polysaccharides are intricately embedded within a whole-food matrix, featuring a naturally occurring complex branched structure.

The core chemical mechanism that enables water retention is the same for both. The key difference is that the Tremella polysaccharides that support hyaluronic acid activity come in a form that you can simply consume as whole food.

Hydration from the Inside Out

The concept of inside-out hydration is not about pursuing a single compound—it centers entirely on building good habits.

Rather than viewing hydration as simply a matter of drinking enough water, this approach frames it as an integral part of your overall eating habits. Once you establish the right routine, it will naturally support proper hydration; all you need to do is prioritize regularly eating water-rich foods.

Even the most effective mechanism is useless if left unmaintained. If you abandon a perfect plan by Wednesday, it will always lose out to a simple plan that you stick to consistently. The approach that lasts is the one that aligns with your daily routine—the one that feels natural and effortless.

Make hydration an enjoyable experience by choosing foods with a soft, water-rich texture.

A Hydration Ritual Worth Looking Forward To

Tremella's water-holding properties are transformed into edible hydration by DEW DO, ensuring it is both ready to sip and easy to maintain.

When you open a jar of it, you'll immediately notice its smooth, hydrating texture, with a clean profile and a faint natural sweetness. You can spoon it into yogurt, fold it into your breakfast bowl, or stir it into homemade drinks.

It harnesses the plant's natural water-retention properties to create an ingredient you can reach for every day. For us, this is the simplest form of daily nourishment to maintain.
