I had a beautiful manicure — until mold grew on my nails

She’s got a green thumb — but it’s nothing to brag about.

A woman was left horrified after she appeared to grow mold under her acrylics, realizing she was the victim of a common manicure mistake.

Rings of fungus now decorate her bare nails, she shared in a viral TikTok, which has grown to over 248,000 views since it was posted last week.

“Your sign not to keep infilling and just give your nails a break,” the user, who goes by @cleancookfun, wrote on the clip.

Acrylic nails are applied with nail adhesive — if done with faux tip extensions to lengthen the nail — and powder, which is sealed onto the nail.

Improper application, or lifts and cracks in the acrylic, can lead to a nasty fungal infection if moisture becomes trapped between the product and the natural nail.

Skipping regular soak-offs and receiving continuous fills for acrylics — or not taking the product entirely off every few weeks and just re-applying it on top when the nail has grown out — can give way to moisture-loving fungi.

Heathline recommends at-home treatments for mild cases, while more advanced infections might require a doctor’s prescription.

“Feel so manky,” the TikToker captioned the clip as she showed off her green-tinged natural nails.

Other manicure enthusiasts filled the comments section with remedies and advice, with some disparaging the unnamed nail technician who performed the work.
