What is trans-epidermal water loss in skin

Healthy skin is determined by a complex arrangement and interaction of a number of factors. This case study presents a clinical trial that aimed to evaluate an oral supplement's effect on some of these skin dimensions.

Challenges and objectives

The experience that the Atlantia team offered when designing and performing skin studies to support a health claim was a controlling factor in the success of this partnership.

The main objective of the clinical trial was to establish the impact on Trans-Epidermal Water-Loss (TEWL) following 12-week daily consumption of an oral supplement in contrast to a placebo.

Other key objectives of the trial were to determine:

  • Omega-3-index
  • Skin firmness
  • Skin hydration
  • Skin Lipid content
  • Subjective evaluation of Skin quality, hydration, moisture and elasticity

How Atlantia’s solution helped

Atlantia’s team is trained and skilled in evaluating skin indications using specific study equipment. Their experience and expertise in designing and performing studies to ICH-GCP standards were major influences and factors in this partnership.

About the study

The study was a randomized, double-blinded, parallel, placebo-controlled clinical trial which drew from a healthy adult population. The study necessitated visits over a 15-week period to conduct a 12-week intervention period while obtaining study objectives at each participant's visit.

Trans-Epidermal Water Loss (skin barrier function) was evaluated using TEWAMeter®, skin firmness using Cutometer®, skin hydration using Corneometer® and Omega3-index using a finger-prick blood test.

Subjects were subjected to a screening process in order to identify eligible participants. All participants were randomized. Study subjects orally consumed one capsule of investigational product each morning of the intervention period.

Participants completed the consenting process and were appropriately informed to provide written consent prior to the screening visit. Participants underwent a screening visit to assess their eligibility for the study, and if all eligibility requirements were met, they were scheduled for a follow-up visit.

At subsequent visits, participants were further evaluated for eligibility, and if each of the inclusion/exclusion criteria were satisfied, baseline assessments were conducted, and randomization of the participants into one of two treatment groups was performed to a ratio of 1:1.

After 12 weeks of supplementation of the investigational supplement, fascinating and intriguing findings were seen concerning an improvement in TEWL and Omega-3 Index blood spot levels when compared to the placebo.

While there were anomalies in the data, this is not atypical given the wide range of factors that can influence TEWL. Further investigation may offer further insight and information on these findings.
