Frequently Asked Questions

Spicules (INCI: Hydrolyzed Sponge) are the skeletal structures of sponges, primarily composed of silicon dioxide (SiO₂·nH₂O) in the form of microscopic needle-like structures. They are a siliceous extract obtained from freshwater sponges. With a diameter of tens of micrometers, these micro-needle structures form physical microchannels when applied to the skin, enhancing the penetration of active ingredient.

Current raw materials are obtained from natural cultivation in clean waters. Freshwater sponges are sensitive to water quality and only grow in clean water. Harvesting occurs once a year in autumn, with a 2-year inventory maintained year-round for stable supply.

Selection is typically based on skin sensitivity and purpose: 100–150µm (Fine) for sensitive skin and first-time users; 150–200µm (Regular) for normal skin and home daily care; 200–250µm (Medium) for concentrated acne and pigmentation care; 250–320µm (Intensive) for anti-aging and professional treatments. As a naturally derived material, spicules have inherent size variations; the typical range is length 180–250µm, diameter 10–20µm. We are open to discussing custom size requirements.

Yes. Spicules have completed human trials at P&K Skin Clinical Research Center: an N=52 human patch test obtained a "non-irritating" determination; OECD TG standard cytotoxicity testing showed IC50 > 5,000µg/ml, confirming excellent safety. While spicule treatments are generally well-tolerated, transient irritation (mild redness or prickling) may occur and usually subsides quickly. Overuse or high concentration can compromise the skin barrier; those with rosacea, active acne, or weakened barriers should exercise caution or seek professional advice.

INCI name: Hydrolyzed Sponge.

Water extract. To protect intellectual property, factory visits are not permitted at this time.

Yes. BS hydrolyzed sponge passes irradiation treatment after production. We still recommend that customers consider a further irradiation step before their own manufacturing, depending on their production requirements.

Clumping is a normal phenomenon after the powder absorbs moisture. Simply crush it with a metal spoon, and the powder can be used again. The dampness will not affect its performance.

The color of hydrolyzed sponge can vary naturally from batch to batch, primarily due to differences in the freshwater sponges sourced (lake/stream origin, harvest season, growth cycle). While identical color cannot be guaranteed, BS assures strict quality controls: extraction and processing methods are rigorously standardized for every batch, ensuring that key active content and performance remain consistent and reliable for production needs.

1) Color: BS — white; Russian & other Chinese — often grey, yellow, brown, or green.
2) Spicule content: BS offers four precise specifications — 99%, 80%, 70%, and 50%.
3) Particle size: BS maintains the natural size of freshwater sponge spicules through controlled sieving.
4) Impurity level: BS — extensive purification keeps impurities below 1%, avoiding allergy or irritation risks from heavy metals and contaminants; Russian & other — often direct whole-sponge powder with silt, debris, bacteria, heavy metals, and microorganisms, with impurity content up to 80%, including decomposing organic matter.

You can apply through the sample request page on our official website, or email Sale@bestspicule.com. BS provides free samples of 3g for testing (freight to be covered by the requester). Samples are accompanied by a COA (Certificate of Analysis) and MSDS and are shipped within 3–5 business days after confirmation.

The Standard Line starts at a minimum of 1kg; Customized products require separate negotiation through B2B consultation. For orders exceeding 10kg, a discount price is available.

Lead time depends on order volume and product specifications. Standard samples ship within 3–5 business days after confirmation. For bulk orders, please contact us for a specific schedule.

Yes. BS has export track records to 30+ countries, with key markets including Korea, Japan, the United States, and Europe. BS also accounts for approximately 90% of suppliers in the Chinese market for hydrolyzed sponge, with products widely re-exported overseas. We provide documents compliant with local regulations (TDS, MSDS, COA, etc.).

Yes. In addition to spicule raw material supply, we offer OEM/ODM formulation development services, including customized functional ingredient combinations, dosage forms (cream, serum, powder), and packaging. For detailed inquiries, please use B2B consultation.

We are currently in discussions regarding licensing of core technologies such as enzyme refining processes and cultivation technology. Please send the technology of interest and your usage plan to Sale@bestspicule.com; we will respond after review.

We welcome joint research with academic institutions, research institutes, and corporate research teams. Send your research objectives, institution information, and research proposal to our email; joint research can begin after signing an MOU.

It is used for troubled skin such as acne, folliculitis, light wrinkles, and oily skin.
1) In salon and skin clinic: used for peeling treatment. Compared with other similar applications, hydrolyzed sponge provides pure physical stimulation—it does not damage the dermis, does not cause bleeding, and does not produce side effects.
2) As a single key ingredient: added to peeling cosmetics such as massage cream, providing peeling functions and addressing skin imitation and pore enlargement.

Spicules continue to work deep within the skin for up to 72 hours post-treatment, creating sustained microchannels for active ingredient delivery.

Mild tingling or redness is a normal reaction when spicules form microchannels in the skin, typically subsiding naturally within 30 minutes to 2 hours. For sensitive skin, start with a smaller size (100–150µm) or reduce the amount used. Sunscreen is essential: exposure to UV rays while microchannels are present can worsen pigmentation. Use sunscreen with SPF 50+ PA+++ or higher, and avoid direct strong sunlight for 2–3 days after treatment.
