Spicules have been floating around in Korean dermocosmetic circles for a while now, but lately they’ve started showing up in more and more over-the-counter skincare.

So what are they? Basically, spicules are micro-needles (usually from marine sponges) that gently prick the skin to increase cell turnover and enhance absorption. Sounds intense — and it kind of is.

The first time I used a spicule serum, I didn’t know what to expect. I applied two pumps and patted it in as usual… and then came the tingle. Not a burning feeling, more like static electricity under the skin. It lasted about 30 minutes. My skin didn’t get red, but I could tell something was happening.

The next morning? My skin felt incredibly smooth, like I had gently exfoliated without any peeling or dryness. But the texture stayed “buzzed” for a day or so, and it made layering other products feel strange . Like they were sitting on top rather than sinking in.

Here’s what I’ve learned after testing four different spicule products over the past two months:

• They’re not for beginners. If your skin barrier is already compromised or you’re using a lot of actives, this might be too much.

• You do need to simplify your routine when using them. No acids, no retinoids, nothing too emollient right after.

• The results are real. Softer skin, improved tone, fewer clogged areas — but only when used with caution.

Would I recommend them? Yes — but with a huge caveat. Think of spicules as exfoliation with a learning curve.

Don’t jump in expecting miracles. Do your research. Patch test. And most importantly, know when your skin needs stimulation and when it needs to just… rest.
