Trial summary

Zinc is an important metal for the maintenance of healthy skin and wound healing. Washing with detergents e.g. shower gels may deplete the zinc stores in the skin. The purpose of our study is to see whether repeated washing with zinc containing shower gel of superficial wounds will result in increased healing. Read more about this study

About this study

Official title: Effects of Shower Gel With Zinc on Epidermal Regeneration

Zinc is an important metal for the maintenance of healthy skin and wound healing. Washing with detergents e.g. shower gels may deplete the zinc stores in the skin.

The purpose of our study is to see whether repeated washing with zinc containing shower gel of superficial wounds will result in increased healing.

Read the detailed description

Zinc is a trace element abundantly present in skin with a concentration gradient from the upper stratum corneum layer to the basal layer. This fact probably reflects the necessity for zinc as co-factor in numerous enzymes involved in skin homeostasis and wound healing. Theoretically, showering with surfactants increases the loss of zinc by the shedding of the zinc-rich corneocytes. Thus there is a concern that this forced exfoliation will result in suboptimal zinc levels for the maintenance of physiological processes involved in epidermal homeostasis and repair. A logical development would thus be to supplement shower gel with zinc to compensate for this loss.

In 30 healthy volunteers one epidermal wound (10 mm in diameter) is induced by suction and heat on each buttock. The wounds are washed with shower gel containing zinc, placebo shower gel or water (reference). The treatments are allocated by randomization ensuring that 20 wounds are washed with shower gel containing zinc, 20 wounds are washed with placebo shower gel and 20 wounds are washed with water.

Being tested
Shower gel with zinc, Plain shower gel, Distilled water

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Epidermal regeneration

    Epidermal regeneration will be assessed blindly by histomorphometry in hematoxylin-eosin-stained paraffin sections of the wounds and by optical coherence tomography.

    Measured: Day 4

Secondary outcomes (5)
  1. Bacterial growth

    Swabs are taken from wounds and adjacent, treated skin.

    Measured: Day 4

  2. Skin barrier function

    Skin barrier function is measured by transepidermal water loss by an instrument from Cortex.

    Measured: Day 4

  3. Keratinocyte proliferation

    Immunohistochemical detection of Ki67 in paraffin sections of the wounds using mouse monoclonal antibody (MIB-1).

    Measured: Day 4

  4. Matrix metalloproteinase (MMP)-1 expression

    Immunohistochemical detection of MMP-1 in paraffin sections of the wounds using mouse monoclonal antibody.

    Measured: Day 4

  5. Pain

    Pain is assessed on a VAS scale (0-100 mm) by the participant.

    Measured: Days 0, 1, 2, 3 and 4

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Epidermal regeneration (time frame: Day 4). It is what the study was designed to measure, not a finding.
