Quick answer: The grey "worms" that roll off your skin when you exfoliate are dead skin cells. They are completely normal and not a sign you're dirty. They show up when real friction lifts the layer of dead cells sitting on your skin's surface. If you've only ever washed with a soft plastic loofah, that layer has probably never been properly removed, which is why the buildup looks so dramatic the first time you really exfoliate.
In the video, I'm holding up a white exfoliating cloth, mid-rant, with the on-screen text: "when people call me dirty because they see the grey worms coming off my skin, but they've only ever washed themselves with a plastic loofah 😬" The caption: "if i don't see the skin worms, i'm not clean enough!"

What are the grey "worms" that come off when you exfoliate?
Your skin sheds an estimated 30,000 to 40,000 dead cells every minute, according to the American Academy of Dermatology. Most of them flake off without you noticing. But the outermost layer of skin can build up into a dull, slightly rough film, especially if you never physically exfoliate.
When you finally use real friction, like an exfoliating mitt, that built-up layer rolls up into little grey pills. The grey color is just dead skin mixed with your skin's natural oils and whatever was sitting on top, like lotion or sunscreen. It's not dirt, and it's not a hygiene problem.
The people calling it dirty have it exactly backwards: the "worms" are proof the exfoliation is working.
Why doesn't a plastic loofah do this?
That mesh pouf in your shower is great at making bubbles. It is not great at exfoliating.
- It's too soft. Thin plastic netting glides over the skin without enough friction to lift built-up dead cells.
- It's a bacteria hotel. The netting traps moisture and dead skin in its layers, and most people keep the same one for months. Dermatologists have been side-eyeing loofahs for years for this reason.
- It feels like it worked. You scrubbed, you feel squeaky, but the dead layer never went anywhere. It keeps building until the day you use a real exfoliating tool.
We break this down further in exfoliating gloves vs. loofahs.
How to exfoliate your body the right way
1. Soak first. 5 to 10 minutes in a warm (not hot) shower or bath softens the dead layer so it lifts easily.
2. Mitt on bare, wet skin. No soap. Soap makes the mitt slip instead of grip. Work in firm but light circles, one area at a time.
3. Stick to 1 to 2 times a week. More than that irritates fresh skin instead of removing dead skin. Over time the "worms" get less dramatic, and that means it's working.
4. Moisturize after. Freshly exfoliated skin soaks up lotion or body oil beautifully. Apply it while skin is still slightly damp.
5. Replace your mitt every 8 to 10 weeks. Rinse it after each use, hang it to dry fully, and swap it out so the texture keeps working.

Do you need to see "skin worms" to be clean?
My caption was a joke, mostly. Watching dead skin roll off is satisfying, but it isn't the goal every time. Once you exfoliate regularly, there won't be much buildup left, and that's the win. Clean skin doesn't need to produce "worms" on demand. It just needs the dead layer gone before it turns into the dull, rough, ingrown-prone surface most of us are walking around with.
FAQ
What are the grey worms that come off when I exfoliate?
Dead skin cells. They're the built-up outer layer of your skin mixed with natural oils, rolled into little pills by friction. It's completely normal and a sign your exfoliation is working.
Does seeing dead skin roll off mean I'm dirty?
No. Everyone's skin sheds constantly. Visible "worms" just mean dead skin had built up, usually because regular washing never removed it, and it's now coming off.
Why doesn't my loofah remove dead skin?
Plastic mesh loofahs are too soft to create real friction against built-up dead skin. They make lather and clean the surface, but they don't really exfoliate. A textured exfoliating mitt does.
How often should I exfoliate my body?
1 to 2 times a week for most people. Too often leaves skin red and sensitive. Too rarely lets dead skin build back up into dullness, rough patches, and ingrown hairs.
Are plastic loofahs bad for your skin?
They're not dangerous, but they don't exfoliate well and they can hold bacteria if they stay damp for months. If you love yours, replace it often and don't rely on it for exfoliation.
The bottom line
Grey "skin worms" aren't gross. They're dead skin finally leaving. Soak, use a real exfoliating mitt on bare wet skin once or twice a week, and moisturize after.
