Deep skin hydration meter

Use cases of MoistureMeterEpiD in skin research

MoistureMeterEpiD is a professional deep skin hydration meter belonging to our family of skin hydration measurement devices. It is widely used in dermatological research, cosmetic testing, and clinical research to assess water content throughout the entire epidermis rather than only the stratum corneum.

The unique measurement depth of MoistureMeterEpiD enables investigation of skin hydration beyond the skin surface. Measurement at this depth has been used to study the effects of skincare routines on deep skin hydration and to monitor the long-term effects of injectable skin hydration treatments in large clinical studies. By providing objective information on epidermal water content, the device supports evaluation of product efficacy, treatment outcomes, and formulation performance.

Understanding hydration throughout the epidermis is particularly important when assessing long-term changes in skin hydration, as improvements in deeper skin layers are ultimately reflected in the hydration status of the stratum corneum and the visible condition of the skin surface. In other words, sustainable skin hydration develops from the inside out, making assessment of the entire epidermis highly relevant for long-term hydration research.

With its speed, portability, and objective measurement principle, MoistureMeterEpiD provides reliable epidermal hydration data for research, cosmetic science, and advanced skin hydration assessment applications.

How to choose between skin hydration measurement devices?

MoistureMeterEpiD is designed for precise deep hydration measurement within the epidermis, while Delfin’s other instruments focus on different layers of skin water content and aspects of barrier function:

‍

MoistureMeterSC – Surface Hydration Measurement (< 30 μm)

MoistureMeterSC measures skin hydration in the stratum corneum, the outermost layer of the skin. Ideal for product and formulation research, claims validation, efficacy testing, and assessment of irritant and allergic skin reactions where changes occur primarily at the skin surface.

‍

MoistureMeterEpiD – Epidermal Hydration Measurement (0.5 mm)

MoistureMeterEpiD measures water content throughout the entire epidermis, providing insight beyond surface hydration alone. Particularly suitable for product and formulation research, claims validation, skincare routine evaluation, transdermal drug penetration studies, injectables research, and assessment of irritant and allergic skin reactions.

‍

MoistureMeterD Compact – Tissue Water Assessment (2.5 mm)

MoistureMeterD Compact measures tissue water content deeper in the skin, making it ideal for assessing swelling and edema, monitoring blood circulation-related changes, wound healing, burns, and other conditions involving fluid accumulation within the tissue.

‍

Multiprobe MoistureMeterD – Layer-Specific Tissue Water Analysis (0.5–5.0 mm)

Multiprobe MoistureMeterD enables tissue water assessment at multiple depths to match specific research objectives:

• 0.5 mm: Product and formulation research, claims validation, transdermal drug penetration, injectables, skincare routines, irritant and allergic skin reactions
• 1.5 mm: Transdermal drug penetration, injectables, irritant and allergic skin reactions
• 2.5 mm: Blood circulation studies, swelling and edema assessment, wound healing, burns and thermal injuries
• > 5 mm: Subcutaneous tissue metabolism studies and cellulite treatment evaluation

By selecting the appropriate measurement depth, researchers can evaluate hydration and tissue water changes from the skin surface down to the subcutaneous tissue layer.
