Ever touched someone's hand or arm and thought, 'How is your skin so smooth?' You're not the only one. But don’t rush to grab the lotion just yet: A recent study from University College London suggests that the softness we feel when touching others' skin may actually be an illusion.
In this study, published in Current Biology, the researchers discovered that people often perceive others’ skin as smoother and softer than their own. In six different experiments involving 133 participants, they examined whether individuals could accurately determine whose skin was objectively softer.
Participants consistently believed their own skin was rougher than their partner’s, even when there were no noticeable differences. This perception mainly occurred when stroking the forearm, an area where hair follicles help transmit pleasurable sensations. Interestingly, the same effect wasn’t observed when touching the palm, a part of the body that people generally don't enjoy having stroked. The illusion was stronger with slow, rather than fast, strokes—something people tend to prefer. These findings suggest that perceiving someone’s skin as soft might lead to more enjoyable and affectionate interactions.
The researchers suggest that this mechanism may play a role in strengthening social connections between loved ones, ensuring that physical touch is an enjoyable experience (since nothing fosters closeness quite like gentle touches). It’s also possible that this illusion may differ when touching a friend compared to a stranger, but that would require further exploration in another study.
