If you’ve discovered a freckle on your wrist, you’re definitely not alone.
A post on Twitter/X recently made a significant number of Internet users realize that many of them share this common feature.
While having a freckle on your wrist isn’t particularly rare, the collective realization has led some to ponder whether it’s merely a coincidence, or if there’s a specific reason behind so many people having this same melanin spot.
Back in 2019, over 10,000 users participated in the discussion on Twitter, and the conversation has since made its way to TikTok with even more people sharing their freckles. Interestingly, there are at least two plausible explanations for this widespread phenomenon, both of which are far more reasonable than the fanciful idea of a microchip implanted at birth, as some have humorously suggested online.
In 2019, TIME magazine consulted two doctors about the freckle phenomenon, and they both provided straightforward explanations for what had become an Internet sensation.
“Freckles are basically areas of the skin where you have more pigment or melanin deposition from UV radiation,” explained Dr. Joyce Park, a dermatologist from the Bay Area.
Given that our arms and wrists are frequently exposed to sunlight when we’re outside, it makes sense for these areas to have more melanin than others. This is especially true considering we often neglect to apply sunscreen to our hands and wrists compared to our face and shoulders.
“The forearms, the wrists, and the hands are really common spots to get that exposure,” Dr. Park elaborated.
“If you think about it, when you’re driving, that side of your wrist and hand are just constantly being exposed to sunlight, even if you’re wearing sleeves.”
However, a New York City dermatologist provided an alternative explanation for why dark spots on your hands and wrists are so common. Dr. Joshua Zeichner suggested that what we’re observing on our wrists might not be freckles at all.
“What we are actually seeing in these photos are moles or ‘beauty marks,’” he clarified. “These spots are harmless overgrowths of pigment-producing cells, causing small brown spots on the skin,” he added.
Regardless of whether they are freckles or moles, all melanin spots should be monitored regularly for any changes in size, shape, or color. If you notice any alterations, it might be wise to consult your doctor. And, of course, don’t forget to apply sunscreen, regardless of the weather.
