Skin Homeostasis in the context of Space Tourism : Towards the development of specialized skincare protocols and interventions for space travelers

Skin Challenges Task Force Group will be launching a call for projects on the topic : “Skin Homeostasis & Space Tourism”.

What is the concept of Skin Homeostasis in the context of Space Tourism?

Space tourism, the concept of offering commercial trips to space for recreational purposes, poses unique challenges for human physiology, including skin homeostasis. Skin homeostasis refers to the maintenance of a healthy and balanced state of the skin.

Addressing the challenges to skin homeostasis in space tourism requires a multidisciplinary approach involving dermatologists, scientists, engineers, and space agencies. By considering the unique conditions and potential risks associated with space travel, it is possible to develop strategies and technologies that support skin health and homeostasis during these extraordinary experiences.

Here are some considerations regarding skin homeostasis in the context of space tourism:

  1. Microgravity Effects: Extended periods of exposure to microgravity can affect the skin. Microgravity leads to changes in blood flow, fluid distribution, and tissue mechanics, which can impact the skin’s ability to regenerate, maintain moisture, and regulate temperature. These changes may result in dryness, skin barrier dysfunction, and impaired wound healing.
  2. Radiation Exposure: Space tourism exposes individuals to higher levels of radiation, including cosmic radiation and solar radiation. Prolonged exposure to radiation can damage skin cells and affect the skin’s ability to repair and regenerate. This may lead to an increased risk of skin aging, DNA damage, and potential skin cancer risks.
  3. Environmental Conditions: Spacecraft and space stations have controlled environments with low humidity levels and recycled air. These conditions can contribute to skin dryness, irritation, and impaired skin barrier function. The limited availability of fresh water and the absence of gravity-induced circulation can make skincare routines and maintaining proper hygiene more challenging.
  4. Skin Protection: Adequate skin protection measures are essential for individuals participating in space tourism. This includes the use of effective sunscreens with broad-spectrum protection against ultraviolet (UV) radiation. Additionally, protective clothing, such as specialized space suits, should be designed to shield the skin from radiation and other environmental hazards.
  5. Skincare and Moisturization: Developing skincare routines specifically tailored to the space environment is crucial. Moisturizers and skincare products with humectants and occlusive ingredients can help combat dryness and maintain skin hydration. Innovative technologies and formulations that target skin barrier function and promote skin repair may also be explored.
  6. Research and Adaptation: As space tourism evolves, continuous research is necessary to understand the specific effects of space travel on skin homeostasis. This includes studying the impact of microgravity, radiation exposure, and environmental factors on skin health. Findings from such research can inform the development of specialized skincare protocols and interventions for space travelers.
