When finishing house missions, astronauts have observed that their pores and skin is thinner, drier, and extra vulnerable to cuts and bruises—all of that are signs of sped-up pores and skin ageing. This intel caught the attention of researchers at PCA Pores and skin, who launched into house on February 19, 2022 with a brand new mission: Determining how microgravity impacts our pores and skin well being within the hopes of bringing the findings into new anti-aging know-how right here on Earth.
The science of microgravity and pores and skin
Microgravity is a state during which gravity could be very low, and the absence of gravity can really be felt and observed (which is completely different from “zero gravity,” a time period that means there is not any gravity in any respect). It is the results of a extra managed surroundings inside house—i.e., what you’d expertise in an area station—so you can float by way of the air effortlessly or transfer a historically heavy object with full ease.
There has already been intensive analysis on how microgravity causes elevated irritation and vital adjustments to our microbiomes. “We all know from historic information that house journey and prolonged publicity to microgravity have profound results on the pores and skin,” says Lia Arvanitidou, Vice President of worldwide know-how and design for Colgate-Palmolive’s pores and skin well being companies (Colgate-Palmolive acquired PCA Pores and skin in 2017). She provides that along with pores and skin thinning and dryness, astronauts additionally see their pores and skin taking longer to heal from environmental stressors just like the solar and bodily trauma like cuts and bruises.

What is going to the mission accomplish?
The massive query right here, although, is why, which is exactly what PCA Pores and skin is making an attempt to decipher. By way of this mission—which was carried out in partnership with NASA and marks the primary private-sector pores and skin well being experiment ever to be carried out in outer house—the model is exploring how, precisely, microgravity accelerates the ageing course of. The objective is to raised perceive how pores and skin ages in the sort of high-stress surroundings.
To do this, the model despatched reside pores and skin tissue samples as much as the Worldwide Area Station. Over the course of seven days, researchers monitored adjustments within the tissue on the molecular degree. “Throughout the reside pores and skin tissues, we’ll see what biomarkers or genes which can be going to alter,” says Lia.
The mission will examine the size of time it takes for pores and skin to indicate indicators of ageing like thinning, dryness, and lack of elasticity in house versus on Earth. The analysis crew anticipated that they’d see extra dramatic indicators of tissue injury in house inside a really quick timeframe, and Lia explains that they’re going to additionally be capable of consider how pores and skin makes an attempt to guard and restore itself towards environmental stressors.
“This research will assist us higher determine areas for intervention and assist us design and develop merchandise that may be breakthrough improvements for ageing,” she says. Finally, the model will use its analysis to develop new anti-aging merchandise.
Whereas we’ve got a fundamental understanding of how the human physique ages and what it must compensate for its losses over time, we nonetheless do not have the entire image. The hope is that this mission will encourage breakthrough science inside the magnificence house and pinpoint new findings to assist us higher look after our our bodies as we become old—which might (pardon the pun) launch the improvements we’ll see 50 years from now.
