A Cardiff University study suggests that men wearing face masks “look more attractive”.

The study, published in Cognitive Research: Principles and Implications, measured how different types of face masks changed the attractiveness of forty male faces.

They discovered the type of covering matters. WalesOnline reports blue medical masks were found to increase facial attractiveness more than other types of masks.

Dr Michael Lewis, a reader from Cardiff University’s School of Psychology and an expert in the psychology of faces, said “Research carried out before the pandemic found medical face masks reduce attractiveness – so we wanted to test whether this had changed since face coverings became ubiquitous and understand whether the type of mask had any effect.

“Our study suggests faces are considered most attractive when covered by medical face masks. This may be because we’re used to healthcare workers wearing blue masks and now we associate these with people in caring or medical professions.

“At a time when we feel vulnerable we may find the wearing of medical masks reassuring and so feel more positive towards the wearer.”

The study also found that faces are considered significantly more attractive when covered by cloth masks than when not covered.

Michael Lewis said “Some of this effect may be a result of being able to hide undesirable features in the lower part of the face – but this effect was present for both less attractive and more attractive people.”

In the study forty three female participants rated the attractiveness of images of male faces without a mask, wearing a cloth mask, a blue medical face mask, and holding a plain black book covering the area a face mask would hide, on a scale of one to ten.

The research was conducted in February 2021, seven months after face masks became mandatory in the UK.

Michael Lewis said “The results run counter to the pre-pandemic research where it was thought masks made people think about disease and the person should be avoided.

“The current research shows the pandemic has changed our psychology in how we perceive the wearers of masks. When we see someone wearing a mask we no longer think: ‘That person has a disease, I need to stay away’.

“This relates to evolutionary psychology and why we select the partners we do. Disease and evidence of disease can play a big role in mate selection – previously any cues to disease would be a big turn off. Now we can observe a shift in our psychology such that face masks are no longer acting as a contamination cue.”

Further work is being conducted with female and male participants to see if the results are true for other genders.
