Microneedling in a bottle

I’ve been seeing post all over social media talking about “Microneedling in a bottle” and how professionals adopting it into the treatment room. From my understanding they are referring to Spicule Skincare.

Spicules are microscopic needle-like structures from marine sponges. They’re usually made of silica or calcium structures that naturally exist in sponge skeletons.

How Spicule Products Work

The process happens in three main steps:

1. Micro-stimulation

Spicules physically poke the skin surface when you massage the product in.

This creates micro-injuries that trigger repair and collagen signals.

Typical spicules are about 0.15 mm long, much smaller than professional microneedles.

2. Ingredient delivery

Many spicules are hollow or porous, meaning they can carry ingredients such as:

• peptides

• vitamin C

• PDRN

• exosomes

These ingredients enter the micro-channels created in the skin.

3. Natural shedding

Spicules don’t stay in the skin permanently.

They gradually break down or shed through the normal skin renewal process over a few days.

Do you think spicule products are a legitimate innovation for ingredient delivery, or just another skincare trend?
