简要总结

The goal of this clinical trial is to investigate the impact of elevated indoor CO2 levels on skin barrier function and inflammation in healthy adults. The main questions it aims to answer are:

How do increased indoor CO2 levels contribute to type 2 inflammation and barrier dysfunction in human skin? What is the demonstrable impact of high CO2 exposure on the human skin barrier and transcriptome? Participants will be exposed to controlled levels of CO2 in either well-ventilated or non-ventilated (closed) bedrooms.

We will evaluate epithelial barrier function by electrical impedance spectroscopy (EIS), collect skin biopsy samples, and investigate the change induced by high indoor CO2 exposure. Healthy adults meeting the inclusion criteria will be included and those with chronic skin conditions, allergies, or recent systemic therapy will be excluded.

Researchers will compare participants exposed to elevated CO2 levels in closed bedrooms with those in well-ventilated bedrooms to determine if skin barrier integrity and transcriptome variations are observed.

详细描述

  1. Core Message:

Elevated indoor CO2 levels in closed rooms may contribute to skin barrier dysfunction and inflammation. Understanding the impact of increasing CO2 on the skin is essential to public health. 2. Supporting Information:

Atopic dermatitis (AD) affects a significant population, and indoor CO2 levels are rising in the bedroom.

Preliminary studies demonstrate the association between CO2 exposure and skin barrier dysfunction.

Skin barrier functions can be assessed by electrical impedance spectroscopy (EIS) in vivo. 3. Key Points:

入选标准

  • The study population will consist of healthy adult volunteers;
  • age between18 and 65 years,
  • Generally healthy and able to provide written informed consent.
  • The choice of healthy adult volunteers without pre-existing skin conditions on site or allergies against tested products is justified.

排除标准

  • Severe dermatitis, eczema, psoriasis, or other chronic skin conditions.
  • History of hypersensitivity or allergies to tested product ingredients.
  • Current or recent systemic therapy for a skin condition in the past six months.
  • Pregnant or breastfeeding individuals.
  • Use of investigational drugs or participation in another trial in the last 30 days.
  • History of skin cancer or malignancies in the study area.
  • Significant sunburn, open wounds, or active skin infections in the study area.
  • Any medical condition that, per the investigator, might compromise safety or confound results.
  • Inability to follow study instructions or attend required clinic visits.
  • Gender Balance: To ensure gender balance, efforts will be made to recruit an equal number of male and female participants.
