What is
Sponge Spicule?
Sponge spicule (Hydrolyzed Sponge) is extracted from a unique freshwater sponge. These fine siliceous needle structures build the sponge skeleton. Chemical formula: SiO₂·nH₂O; length: 100–320 μm, diameter: 10–15 μm.
1. What is Sponge Spicule ?
Sponge Spicule is a substance extracted from freshwater sponges. It is a fine siliceous needle‑like structure that forms the fundamental skeleton of freshwater sponges. Its chemical formula is SiO₂·nH₂O. The spicules measure 100–320 μm in length and 10–15 μm in diameter, roughly 1/3 to 1/5 the thickness of a human hair.
In ascending order of spicule content, the material appears brown, grey and white respectively. Under microscopic observation, the material consists of needle‑shaped micro‑silica spicules with rounded or pointed tips at both ends. Intact spicules range from 100 μm to 320 μm in length and approximately 15 μm in diameter, classifying them as natural biological microneedles.
Thanks to its distinctive siliceous needle architecture, Sponge Spicule can replace conventional metallic microneedles for skin revitalisation treatments and substitute nanoneedles for active ingredient delivery. It also overcomes the application limitations associated with traditional microneedle devices.
2.Sponge Spicule Length
Sponge spicule can be broadly categorized into three types based on microneedle length: 100 μm, 200 μm and 300 μm. With identical application technique, microneedles of varying lengths penetrate the skin to different depths, resulting in distinct primary cosmetic applications.
- 100 μm: Ideal for users seeking a gentle exfoliation experience.
- 200 μm: This depth not only aids stratum corneum renewal, but also stimulates cell metabolism in the stratum spinosum and boosts collagen production.
- 300 μm: Delivers deep cellular stimulation and activation, accelerates metabolism, reduces pore congestion, promotes collagen synthesis, and drastically shortens the natural cell turnover cycle from the typical 28 days to approximately 7 days.
