Detailed Introduction of Sponge Microneedle
Sponge Microneedle (INCI: Hydrolyzed Sponge) is a mainstream natural biological microcrystalline skin renewal raw material in the global cosmetic industry. Different from plant extracts, synthetic microneedles and metal microneedles, it is refined from siliceous spicules of natural freshwater sponge skeletons through low-temperature biological hydrolysis, multi-stage purification and sterile sieving processes. Its core component is high-purity silica microcrystals with trace natural sponge active proteins, featuring stable physical and chemical properties, mild safety and zero irritation.
With a regular microscopic needle-shaped crystal structure, the material forms micro-level non-invasive channels on the skin surface, realizing mild physical exfoliation, pore unclogging and skin microcirculation activation. It significantly improves the transdermal absorption rate of active ingredients such as asiaticoside, glycyrrhizic acid, peptides and antioxidants in skincare products, serving as a core functional raw material for non-invasive skin renewal, acne repair and skin texture improvement formulas.
We strictly control raw material screening and the whole production process to completely remove sponge organic impurities, residual proteins and microorganisms, with precise particle size classification. Each batch features regular needle shape, stable efficacy and negligible batch difference. Complying with EU and US cosmetic import standards, the product has no heavy metal excess or sensitizing residues. It is widely applicable in skin renewal serums, acne masks, repair creams and professional skincare sets, providing one-stop standardized and customizable biological microneedle supply services for global cosmetic manufacturers, formula R&D institutions and raw material traders.
Core Efficacy of Sponge Microneedle
Mild Physical Exfoliation & Skin Renewal:
Micro-scale needle crystals gently metabolize dead skin cells without damaging healthy cuticles, improving rough and dull skin

Common Questions
FAQ About Sponge Microneedle
1. Is sponge microneedle a plant-based raw material?
No. Sponge microneedle (hydrolyzed sponge) is extracted from siliceous spicules of freshwater sponge animal skeletons. It is a biological microcrystalline raw material, not plant-derived or synthetic, and is a globally recognized compliant skin renewal ingredient.
2. Is sponge microneedle safe and non-irritating?
It is biologically inert and non-sensitizing. Pure physical skin renewal does not damage the dermis layer. Mild and non-invasive, it is suitable for sensitive skin and acne-prone skin formulas for both salon and home use.
3. Is it compatible with various skincare dosage forms?
It has stable physical and chemical properties, acid and high-temperature resistant. It is compatible with water phase, serums, creams, masks and most cosmetic formulas without inactivation or deterioration during long-term storage.
4. Is it eligible for EU and US export?
All indicators comply with EU and US cosmetic regulations with complete SGS test reports and compliance documents, supporting smooth customs clearance and registration worldwide.
5. Is batch quality stable?
Adopting standardized biological purification production line and precise particle size classification technology, every batch features negligible differences in needle shape, particle size and efficacy, ensuring highly unified quality for long-term mass supply.
6. What is the core working principle of sponge microneedle?
With natural regular siliceous needle microcrystals, it gently removes dead skin cells and unclogs pores physically, builds micro skin channels, improves the penetration and absorption efficiency of skincare actives, and realizes non-invasive skin renewal.
7. Can different particle size specifications be customized?
Yes, we can customize ultra-fine, conventional and coarse particle sizes according to customers’ formula requirements to match different skin feel and functional formula needs.
8. Are samples and customized services available?
5–20g free samples are provided for formula R&D and testing. Custom particle size, active compounding and OEM private label services are available, with complete export technical documents provided.
