Hydration is one of the most talked-about concerns in skincare, and one of the most misunderstood.
The prevailing assumption is that moisturised skin simply needs more water added to its surface. But the real challenge lies elsewhere: skin continuously loses water through a natural process called transepidermal water loss (TEWL). It is this loss that underlies dryness — and why replenishing moisture alone is often not enough.
Hydration Vaccine (HV) was formulated with this distinction in mind. A lightweight balm, it functions as a hydration management and preservation system: a dual approach that helps add moisture to skin while simultaneously forming a breathable occlusive barrier designed to help minimize that loss.
Let’s explore how the formulation works, what sets it apart, and how to use it correctly within a regimen.
Hydration levels within the skin are determined by two things: the moisture it gains, and the moisture it loses.
Skin is always losing water. This happens continuously through a natural process called transepidermal water loss (TEWL), where water escapes through the skin's outer layers and evaporates. When the skin barrier is compromised by age, poor care or environmental factors such as dry weather, TEWL can become excessive, which can result in an imbalance in the skin's hydration levels.
This is why simply adding topical moisture is not enough. Moisture can continue to escape regardless of how many layers are applied.
Rather than relying on a single approach, HV addresses hydration in two complementary ways: helping to add moisture while also helping to preserve it.
Hydration Vaccine helps effectively combat TEWL, minimising moisture loss while still allowing the skin to breathe. Despite providing rich nourishment, it remains lightweight and comfortable on the skin, ensuring effortless application without feeling heavy. By optimizing hydration, it supports overall skin vitality, helping to plump fine dry lines and increase the skin’s suppleness.
Managing hydration efficiently is important for skin function and appearance. HV contains ingredients that help support hydration by working with moisture-related components and processes naturally present in the skin, including:
Combine complimentary formulations:Layer with MMHC2 ,which provides water-based hydration at multiple levels, and CAIS3 , which helps support the skin's components to enhance its overall appearance. HVthen goes on to seal and preserve moisture.
Use consistently:Apply in the morning and evening, as twice daily helps support the skin with sustained hydration.
Placement matters: HVis best used after serums and before heavier creams or suncream. This matters for optimal absorption and moisture retention.
Consider the Hydration Collection :A curated set of formulations designed to work together to help skin boost and retain moisture.
The key difference is in approach. A standard moisturizer typically works by depositing moisture or creating a surface barrier. Hydration Vaccine operates as a hydration management and preservation system – working in two directions at once. It amplifies the skin’s ability to hydrate itself through the support of hyaluronic acid (HA) precursors, which encourage skin to maintain optimal levels of its own HA and natural moisturizing factors. Simultaneously, it forms a flexo-silicone mesh barrier that is both occlusive and breathable. It is a more deliberate, system-level approach to hydration rather than a surface treatment.
Yes. NIOD specifically recommends pairing HV with MMHC2 and CAIS3 for a layered approach to hydration. Apply those serums first, then follow with HV to seal in their effects. HV is also part of the broader NIOD Hydration Collection,which is designed as a complete, multi-step hydration system.
Yes. Its lightweight, breathable profile makes it appropriate across a wide range of skin types and concerns.
HV's core mechanism, minimizing TEWL, directly addresses one of the primary ways environmental factors affect the skin. TEWL tends to increase in response to environmental conditions, such as a dry climate. By forming a breathable but occlusive barrier and supporting the skin's internal hydration systems, HV works to counteract this process.
Retaining skin hydration is an ongoing challenge, particularly as we age and the skin barrier becomes compromised by environmental and intrinsic factors.
Where most products address dehydration at the surface, HV uses a dual approach that helps add moisture to skin while simultaneously forming a breathable occlusive barrier designed to help minimize that loss.
Long term hydration management is fundamental to healthy-looking skin, and using HV twice a day, every day, can help combat excessive TEWL, plump fine dry lines and support overall skin vitality.
