Spicules 100
Spicules 100 μm uses short, uniformly sized biogenic spicules refined through a solvent-free multi-step purification technology to ensure safety and consistency. The controlled 100 μm length minimizes irritation risk while
Spicules 220 μm applies precision size-control and purification processes to produce medium-length spicules optimized for facial use. The balanced structure delivers controlled mechanical stimulation that supports epidermal regeneration without excessive disruption. This grade significantly improves transdermal delivery efficiency of functional ingredients while maintaining skin comfort. It suits facial formulations designed for daily or treatment-level use that require both safety and visible efficacy.

Spicules 320 μm represents the highest stimulation grade, produced with extended spicule length for scalp and advanced skin applications. The 320 μm structure actively stimulates microcirculation and maximizes delivery of

Spicules Brown (Peeling Care) uses minimally refined biogenic silica needles derived from a self-controlled Spongilla lacustris breeding base to ensure raw material safety and heavy-metal control. The limited purification process
