What Is Spicule Technology? The Science Behind Liquid Microneedling

Meet Spicule: The Ingredient Changing Skin Care Science

At Skin Republic, science drives every formula we create — and few innovations have been as transformative as spicule technology. Often called liquid microneedling, spicule is a marine-derived ingredient that helps active ingredients penetrate deeper into the skin for visible renewal, smoother texture, and refined pores.

But what exactly is it, how does it work, and why are dermatologists and skincare experts calling it the next big thing?

The Origins of Spicule

Spicules are microscopic needle-like structures naturally derived from marine sponges. In skincare, these purified spicules are suspended in a serum or ampoule, where they gently stimulate the skin’s surface. This process creates micro-pathways that improve absorption of key actives like niacinamide, hyaluronic acid and panthenol.

Unlike traditional microneedling, spicule technology is non-invasive — there’s no downtime, no redness, and no damage. Instead, it delivers a gentle exfoliating effect while activating the skin’s natural renewal processes.

How Spicule Technology Works

When applied to the skin, spicules act as microscopic delivery vehicles. As they settle into the upper layers of the epidermis, they:

• Create temporary micro-channels that increase ingredient absorption.

• Stimulate micro-circulation to support collagen and elastin production.

• Encourage gentle exfoliation, improving texture and radiance.

Over time, this leads to refined pores, smoother skin, and improved firmness — the same benefits often associated with professional treatments, but without irritation or recovery time.

The Clinical Difference

In clinical testing, spicule-based formulations have shown measurable improvements in:

• Pore visibility – reduced by up to 34 % after 4 weeks.

• Wrinkle depth – decreased by 31 % after consistent use.

• Skin smoothness and luminosity – visibly enhanced after the first week.

Why Spicule Belongs in Your Routine

Spicule-infused skincare is ideal for anyone looking to:

• Smooth uneven skin texture.

• Minimise visible pores.

• Boost radiance and firmness.

• Enhance the effectiveness of their active ingredients.

It’s suitable for most skin types and can be used two to three times a week as part of your regular skincare routine.
