A dermatologist has revealed when you need to worry about your feet – and why those dry patches may not actually be dry skin, but fungus.

The important information was shared in a new video by Mississippi-based dermatologist Dr. Lindsey Zubritsky, who goes by the username @dermguru on social media.

Dr. Zubritsky often takes to social media to share her skincare tips, tricks, and hacks – but this time, she issued a public service announcement to those who have dry feet.

To start off the video, she showed various pictures of feet that had peeling skin all over them.

She explained that if your feet look like this, you may have foot fungus – or, something more commonly known as athlete’s foot.

‘This does not just occur in athletes, this is one of the most common things I see in clinic as a dermatologist, and I guarantee most of y’all don’t even realize that you’re walking around with fungus on your feet,’ Dr. Zubritsky said.

‘Most people think it’s just dry, cracked feet, when, in fact, they have something called tinea pedis,’ she said, using the medical name for athlete’s foot.

The dermatologist explained that you can tell the difference between athlete’s foot and dry skin due to the fungal infection’s scaly texture and red border.

She said that the ‘dead giveaway’ to a case of athlete’s foot is if you peek between your toes and see peeling or cracked, red skin.

‘Another sign that it may be fungus and not dry skin is if you peep at your toenails, and they look like this,’ she furthered, showing a picture of someone with a yellow patch on their toenail.

‘If your toenails are yellow, thick and crumbly like this, it can mean that this is also fungus,’ she said.

Thankfully, however, there are many ways to treat this in order to get your feet back in good health.

She said that the ‘easiest’ way to get athlete’s foot under control is to get an over-the-counter, antifungal cream like Lotrimin Ultra.

Dr. Zubritsky also suggested diluting distilled white vinegar or Listerine Original Antiseptic mouthwash to use on the affected areas in a foot soak.

But before ending the video, the dermatologist left viewers with another extremely important piece of advice you need to heed while dealing with foot fungus.

‘If you are not cleaning your shoes, you are just going to re-infect your feet all over again,’ she shared.

‘Your shoes are absolutely covered in fungus, so these need to be cleaned, I recommend washing them in hot water if you can, and sprinkling a little antifungal foot powder in your shoes every single day,’ Dr. Zubritsky continued.

She even suggested buying small UV lamps to stick in your shoes every night to ensure that your athlete’s foot is ‘cured for good.’
