What is Spicule?
The Skeletal Structure of Sponges
Spicule is a microscopic siliceous needle-like structure that forms the skeleton of freshwater sponges. With the chemical formula SiO₂·nH₂O, lengths of 100–320 µm and diameters of 10–15 µm, it is roughly one-third to one-fifth the thickness of a human hair.
A Sponge's Defense Structure
Sponges use microscopic crystals called spicules as their skeletal framework to protect their bodies.
Pure Inorganic Silica
The main component is hydrated silicon dioxide (SiO₂·nH₂O) — a purely inorganic structure free of organic matter, leaving no residue on the skin.
Microchannel Formation
When applied to skin, forms microchannels in the stratum corneum, aiding the delivery of active ingredients.
