Spicule serums: what the "microneedle in a bottle" trend actually is
Spicule products are one of the loudest K-beauty trends on TikTok right now. Beauty coverage often calls them "liquid microneedling," which is catchy but a bit misleading.
What's inside Spicules are tiny, needle-shaped silica structures from marine sponges. In serums they are suspended in a liquid. When massaged in, they are said to create very small channels in the top layer of skin, which is why people feel a prickling sensation.
What people report
- A tingly or prickly feeling that can last a while
- Smoother-looking texture over time, according to many reviews
- Temporary redness, especially at higher strengths
Cautions that come up again and again
- Start with the lowest strength and not every day
- Skip it on broken, sunburned or actively irritated skin
- Don't pair it on the same night with acids or retinoids
- Wear sunscreen, since the skin may feel more reactive
- It is not the same as an in-clinic microneedling procedure; ask a professional if you're comparing the two
Would you try a spicule serum, or does the prickle sound like a hard pass?
