Formulation Instability Caused by Chinese Spicule Refining Methods
Chinese spicules are typically refined using strong acids (hydrochloric acid) or bases (sodium hydroxide) to remove impurities. This method can lead to formulation instability over time—especially after 1 to 3 months of storage—due to the following reasons:
Residual Solvents in Spicule Pores
Chemical Reactions & pH Shifts Over Time
Trapped acid or base residues slowly leach into the aqueous phase of the formulation. This delayed release may not show up in early stability tests but can cause issues after prolonged storage.
Leached hydrochloric acid lowers pH (acidic), while sodium hydroxide raises it (alkaline). Most cosmetic formulations are designed to remain stable within a mildly acidic to neutral pH range. Deviations can lead to:
Emulsifiers may ionize or deform, destabilizing the emulsion and causing phase separation.
Gelling agents like carbomer or acrylate copolymers only maintain viscosity within specific pH ranges. A shift can cause liquefaction or breakdown of the gel.
Active ingredients or preservatives may become unstable or react undesirably in altered pH conditions.
Internal Stress & Structural Breakdown
In summary, the use of hydrochloric acid or sodium hydroxide in Chinese spicule refining may leave residual solvents that gradually alter pH and destabilize emulsions or gels—resulting in long-term formulation breakdown.

Spicule Powder – Safe Handling Guidelines
Spicules are fine, needle-like powders that may cause irritation if they come into contact with the skin or are inhaled. To ensure safe handling, the following precautions must be observed:
1. Minimize Skin Contact
Spicule particles can cause severe pain and irritation if they enter the eyes. Always wear protective goggles.
Fine spicule particles may embed into the skin, causing stinging or itching. Use rubber or nitrile gloves to avoid direct contact.
Minimize exposed skin by wearing long-sleeved workwear.
2. Prevent Inhalation
Spicule powder is extremely fine and can easily become airborne. Use a KF94 or industrial-grade dust mask to prevent respiratory irritation.
Work in well-ventilated areas or use local exhaust systems. Avoid working in enclosed spaces.
3. Maintain a Clean Work Environment
Remove residual powder using a vacuum cleaner or damp cloth. Avoid dry wiping, which may disperse particles into the air.
When opening or transferring spicule containers, minimize static electricity and avoid windy or high-vibration areas.
After use, close containers securely to prevent contamination and airborne dispersion.
4. Emergency Preparedness
If spicules contact skin or eyes, rinse thoroughly with running water and seek medical attention if necessary.
Equip the workspace with eyewash stations and emergency showers for quick response.
A.
Optimal Temperature and Timing for Spicule Incorporation in Formulations
To ensure formulation stability and uniform dispersion, spicules must be added at a specific temperature and stage of the process.
Why Temperature Matters
At elevated temperatures, viscosity decreases, causing spicules to settle more easily. This can lead to uneven distribution and reduced product quality.
Excessively low temperatures increase viscosity, making it difficult to mix and disperse spicules uniformly. This may result in clumping or poor spreadability, affecting texture and efficacy.
Therefore, the most effective method is to add spicules gradually at around 30°C during the final stage of formulation and disperse them thoroughly to maintain stability and consistency.
Spicule Sedimentation in Liquid Formulations
When spicules are added to liquid formulations, sedimentation may occur due to their higher density compared to the base. This is a natural phenomenon.
To ensure consumers experience consistent texture and efficacy, it is essential to include clear instructions such as “Shake well before use” on the product label.
This helps redistribute settled spicules evenly throughout the formulation before each use.
A.
Special Handling and Storage Precautions for Brown Spicules
Due to their unique characteristics, brown spicules require extra care during handling and storage. Please follow the guidelines below to ensure safe and effective use:
Brown spicules are manufactured in their natural form without any added preservatives. While this enhances purity, it also makes them more susceptible to microbial contamination.
Prior to distribution, the product undergoes sterilization to minimize initial microbial load.
Since no preservatives are added, it is strongly recommended to use the product immediately after opening. This helps prevent contamination from external environments and maintains product quality.
Leaving the product exposed for extended periods may lead to spoilage or microbial growth.
By strictly following these precautions, you can safely and effectively utilize brown spicules while preserving their natural integrity.

Spicule Size and Concentration Selection Guide
Spicules are available in various sizes, and selecting the appropriate size and concentration depends on the product’s purpose, usage environment, and application frequency.
UNIZ LAB offers a range of spicule sizes including 100µm, 200µm, 270µm, and 320µm.
1. Criteria for Choosing Spicule Size
• Based on Treatment Goals
Larger spicules (e.g., 270µm, 320µm) penetrate deeper into the skin and provide stronger stimulation, making them suitable for targeted treatments.
The 320µm spicule is optimized for scalp care and is effective in hair and scalp treatment products.
Smaller spicules (e.g., 100µm, 200µm) offer a gentler feel and are ideal for daily skincare or products for sensitive skin.
• Based on Usage Environment
Products designed for consumer use typically contain smaller spicules (100µm, 200µm) to minimize irritation and enhance ease of use.
Professionals may select from a range of spicule sizes depending on the client’s skin condition and treatment goals.
Larger spicules may be used for intensive care under expert supervision.
2. Importance of Concentration Control
In addition to size, the concentration of spicules in the formulation significantly affects product efficacy and user experience.
• Adjusting Concentration Based on Usage Frequency
Should contain low concentrations to avoid overstimulation and maintain skin comfort.
May contain slightly higher concentrations for more noticeable effects.
Can include high concentrations for intensive care, but should be used with caution to avoid irritation.
• Balancing Efficacy and Sensation
Even with the same spicule size, higher concentrations increase stimulation and effectiveness, while lower concentrations offer a gentler feel.
Therefore, size, concentration, and usage frequency must be considered together to determine the final product characteristics.
Explore UNIZ LAB’s diverse spicule sizes to find the optimal solution tailored to your product goals, target users, and application cycle.

Spicules Naturally Exit the Skin Over Time
After penetrating the skin, spicules gradually detach and are expelled through the skin’s natural turnover process.
They assist in skin regeneration and typically shed from the surface within approximately two days.
Spicules cannot penetrate deeply into the skin due to its structural characteristics.
Made of silicon dioxide (SiO₂), they do not dissolve inside the skin.
Instead of melting away, they are naturally pushed out as dead skin cells exfoliate.
This makes spicule use safe and reassuring for consumers.
A.
Skin Irritation After Using Spicules – Causes and Relief Methods
1. Micro-Needle-Induced Skin Irritation
Spicules are micro-needle structures made of natural silica extracted from marine sponges.
When applied to the skin, they penetrate and form countless micro-channels.
This process may cause slight wounds and physical stimulation, leading to stinging, itching, or redness—a natural reaction during skin regeneration.
2. Natural Skin Recovery Response (Inflammation)
As spicules penetrate the skin, the body recognizes them as foreign intruders and initiates a healing response.
Immune cells become activated, and a mild, controlled inflammatory reaction may occur, resulting in redness and itching.
3. Increased Skin Sensitivity
Spicule use may temporarily weaken the skin barrier, making it more sensitive to external stimuli like UV rays.
This heightened sensitivity can amplify symptoms such as redness or itching.
4. Overuse or High Concentration
Using high-concentration spicule products too frequently can lead to excessive stimulation.
This may worsen symptoms like redness, itching, and stinging, especially for those with sensitive skin, atopic dermatitis, or rosacea.
5. Allergic Reactions
In rare cases, allergic reactions to certain ingredients in spicule products may cause redness, itching, or swelling.
Relief Methods
1. Focus on Soothing and Moisturizing
2. Minimize Irritation
3. Strict Sun Protection
4. Adjust Product Usage
5. Consult a Dermatologist
If symptoms like itching, redness, stinging, or oozing persist for more than a day or worsen, seek professional help.
Those with pre-existing skin conditions should consult a specialist promptly.
Spicules can support skin regeneration, but reactions vary by skin type and condition.
Use them cautiously, and stop immediately if adverse reactions occur—then consult a dermatologist.
A.
Low-Purity Spicules: Risks and the Importance of High Purity
Some manufacturers may collect residual materials left over from the refining process and sell them as low-purity spicules at a lower cost. However, such low-grade spicules can pose the following risks:
Problems with Low-Purity Spicules
Impurities other than spicules can negatively affect cosmetic formulations, leading to reduced product stability and efficacy.
As by-products of the refining process, low-purity spicules often vary in quality from batch to batch, making it difficult to maintain product consistency.
Recommendation: Use High-Purity Spicules
For these reasons, we recommend using high-purity spicules with controlled concentrations rather than low-purity alternatives. High-purity spicules offer the following advantages:
Consistent and high-grade spicules help maximize product stability and performance.
Fewer impurities mean better synergy with cosmetic bases and reduced risk of unwanted side effects.
At UNIZ LAB, we prioritize product safety and quality above all else. We are committed to providing only the finest raw materials.

Explanation of Spicule Length Variability
Spicule length is not uniform. This is because spicules serve as the skeletal structure of sponges, and their length naturally varies depending on the sponge’s growth stage.
Sponges are living organisms, and as they grow, their spicules form and develop alongside them.
Each spicule may have slightly different lengths depending on the time of formation and environmental conditions during growth.
This variability is a natural physical characteristic of spicules, which are derived from biological sources.

Post-Spicule Skincare Guide for Optimal Results
Spicules are effective for promoting skin turnover and enhancing absorption of active ingredients, but proper aftercare is essential to maintain healthy skin. Here are key tips to help your skin stay in top condition after using spicules:
1. Hydration Is the Foundation
After using spicules, your skin may feel temporarily sensitive or dry.
Apply a generous amount of moisturizer containing ingredients like ceramides, hyaluronic acid, or panthenol to strengthen the skin barrier and soothe irritation.
A strong moisture barrier helps prevent water loss and shields the skin from external stressors.
2. Use Mist Frequently to Stay Hydrated
If your skin feels dry, spritz a hydrating mist throughout the day.
Choose alcohol-free mists with soothing ingredients.
Mists with moisturizing agents are more effective than plain water in calming and hydrating the skin.
3. Sun Protection Is Absolutely Essential
After spicule use, your skin becomes more sensitive to UV rays.
To prevent damage or pigmentation, apply sunscreen thoroughly before going outside.
Use products with SPF 30+ and PA+++, and reapply every 2–3 hours.
Physical (mineral) sunscreens are gentler on sensitive skin.
4. Gentle Care During Exfoliation
Mild exfoliation may occur over several days after using spicules.
This is a natural part of the skin renewal process—don’t worry!
Avoid forcibly peeling or scrubbing the skin.
Instead, wash gently with lukewarm water and let the dead skin shed naturally.
Avoid using exfoliating towels or harsh scrubs.
By following these care tips, you’ll maximize the benefits of spicules and support your skin’s health and glow.
A.
Spicules – Use Them Properly, Not Frequently!
The key to effective spicule skincare is not frequent use, but correct usage based on concentration. Overuse can lead to skin damage, while proper intervals help maximize benefits.
1. Low-Concentration Spicules (0.1–0.3%) – Safe for Daily Use
Products containing 0.1% to 0.3% spicules are suitable for daily use.
They gently stimulate the skin, support healthy turnover cycles, and enhance absorption of active ingredients.
Think of it like light daily exercise—consistent use can improve overall skin condition.
2. Medium-Concentration Spicules (Above 0.3%) – Avoid Daily Use
Products with more than 0.3% spicules should not be used every day.
Spicules work by creating micro-injuries to trigger regeneration.
Using high concentrations daily may cause cumulative damage, weaken the skin barrier, and increase sensitivity.
Always follow the manufacturer’s recommended usage cycle.
3. High-Concentration / Professional Spicules (1% or More) – Minimum One Week Recovery
Spicule products with 1% or more are typically used in dermatology clinics or esthetic treatments.
They must be applied under professional guidance and require at least one week of recovery time between uses.
These potent formulas deeply stimulate turnover and regeneration, so the skin needs time to heal.
Using them too frequently can lead to irritation or skin trouble.
Final Note
Always tailor your spicule usage strategy to the product’s concentration and your skin’s condition.
Following the recommended cycle is the fastest path to healthy, radiant skin!
A.
Exfoliation After Using Spicules – A Normal Skin Renewal Process!
After using spicule-based products, some exfoliation may occur. But don’t worry—this is a normal and expected effect. As spicules penetrate the skin, they promote the shedding of old keratinized cells and stimulate the production of new skin cells. It's like pruning old branches to make way for fresh sprouts—a sign that your skin is regenerating healthily.
Differences in Exfoliation by Skin Type
The level of exfoliation can vary based on skin type:
Tends to have more active sebum production and a thicker keratin layer. As a result, those with oily skin may experience more noticeable exfoliation after using spicules. This is a sign that the thick keratin buildup is being effectively removed.
Compared to oily skin, dry skin may show less visible exfoliation. However, even if not obvious, regeneration is still actively occurring beneath the surface.
Proper Care During Exfoliation
The most important thing during exfoliation is to avoid forcibly removing peeling skin. Scratching or using exfoliating towels can damage your skin by causing unnecessary irritation.
If you notice flaking skin, wash gently with lukewarm water to allow it to fall off naturally—like soaked paper softly sliding away.
Your skin may feel drier than usual during this period, so it’s crucial to maintain moisture and support your skin barrier with proper hydration.
Exfoliation after spicule use is part of the process toward brighter and healthier skin. Just follow the right care techniques to assist your skin’s natural renewal!

Spicules Cannot Be Considered Vegan
Here’s why:
Spicules are extracted from sea sponges, which are classified as animals—even though they may resemble plants in appearance. Biologically, sponges belong to the animal kingdom.
Veganism is based on the principle of avoiding all forms of animal exploitation and the use of animal-derived ingredients. Even though the primary component of spicules is an inorganic substance (silica), their origin being animal-based disqualifies them from vegan categorization.
Therefore, products containing spicules cannot be classified as vegan items
A.
Spicule Extraction Source: Freshwater Sponge
Spicules are micro-needle structures gaining attention in both the beauty and medical fields. They originate from the humble yet ancient organism: the sponge. Sponges are considered one of the earliest multicellular animals to appear on Earth, holding remarkable evolutionary history.
1. Biological Classification & Features of Sponges
2. Source of Cosmetic Spicules: Freshwater Sponges
Not all sponges are used for cosmetic or medical purposes. The ones employed in beauty products are typically extracted from freshwater sponges.
3. Freshwater Sponges & Water Quality
Freshwater sponges do more than supply spicules—they’re important biological indicators of water quality.
In summary, spicules are naturally derived materials sourced from ancient freshwater sponges—organisms that thrive only in the cleanest environments. Their fascinating origin not only adds scientific credibility but also a touch of nature-inspired elegance to skincare.
