Spicules (Micro-Needle Skincare): What to Know First

A serum that feels like tiny pins? Spicule skincare is having a moment in Korea. Read this before you try it.

What are spicules?

Spicules are microscopic needle-shaped particles, usually from marine sponges. When massaged in, they create a prickly feeling and help refresh the skin's surface. Products often list a number in ppm or 'shots' to show strength.

What they do for your skin

• Smoother-looking texture. Skin looks more refined after regular use.
• Fresher surface. Dull surface build-up is refreshed.
• Helps the next step feel more effective. Many people follow with a hydrating serum.

Who it suits

Normal, oily or textured skin that isn't sensitive. Not for broken, sunburnt or very reactive skin.

How to use it

1. Start at the lowest strength, once or twice a week, at night.
2. Massage gently. Don't scrub.
3. Follow with soothing, hydrating products and wear sunscreen the next day.

When you'll notice it: Skin looks smoother after a few uses.

Good to know: Not for active breakouts. A light prickle is expected. Stop if it burns.

What to pair it with

Follow with cica, panthenol or hyaluronic acid. Avoid using acids or retinol on the same night.

Myth vs fact

Myth: The more it prickles, the better it works.
Fact: A light tingle is normal. Pain, burning or redness means stop.

How to choose one

• Look for Spongilla Spicule, Hydrolyzed Sponge, or a strength given in ppm or 'shots'.
• Start with the lowest strength the brand offers.
• A formula that also contains soothing ingredients, such as cica or panthenol, is kinder to skin.
