Exploring the Mysteries of Hydrolyzed Sponge:In-depth Q&A With Us

Date:2025-10-30

Hunan Sunshine Bio-Tech Co., Ltd. has been deeply engaged in the field of hydrolyzed sponge (also referred to as sponge spicule) for over a decade. It remains dedicated to the R&D, production, and sales of hydrolyzed sponge, striving to provide high-quality hydrolyzed sponge raw materials to the market. Our core product, hydrolyzed sponge, is made from carefully selected pure freshwater sponges.As organisms that inhabit marine or freshwater environments, sponges have existed on Earth for more than 200 million years and possess stable natural biological properties. In the production process, we adopt an eco-friendly extraction technology that not only ensures a green and pollution-free production process but also maximizes the retention of microneedle activity in the hydrolyzed sponge, preserving the product's natural attributes and laying a solid foundation for its efficacy.

Questions About Product Characteristics and Others

1. Why is the length of hydrolyzed sponge inconsistent?

Sponges are natural organisms, and the length of their hydrolyzed sponge varies naturally due to factors such as species (freshwater Spongilla fragilis)and growth environment (water quality,nutrients, etc.).Additionally,to retain spicules activity and natural properties,our company uses an eco-friendly extraction process without artificial intervention in hydrolyzed sponge length. As a result, the hydrolyzed sponge length of the final product is inconsistent, which reflects the natural and original characteristics of the product.


2. Where is hydrolyzed sponge extracted from?

Hydrolyzed sponge is typically extracted from pure freshwater sponges. Sponges are simple multicellular organisms that grow in marine or freshwater environments and have lived on Earth for over 200 million years. The sponges we use grow in freshwater basins and lakes in China, which boast a favorable natural environment free from pollution.

3. What are the precautions for using brown hydrolyzed sponge?

Hydrolyzed sponge mainly contains sponge spicules, whose main component is SiO₂—a colorless crystal. When the purification level is high, hydrolyzed sponge appears pure white.However,brown hydrolyzed sponge has a lower purification level and contains other organic substances, resulting in a brown, gray-brown, or other similar colors. It also carries a certain risk of sensitization. For people with sensitive skin, it is recommended to first conduct a local skin test and only expand the scope of use after confirming no allergic reaction. During use, it is also necessary to closely monitor the skin condition. If uncomfortable symptoms such as redness and itching occur, stop using the product immediately and provide soothing care for the skin.


4. What is the hydrolyzed sponge content in your product?

Each gram of hydrolyzed sponge contains at least 5 to 6 million spicules. This data is measured using the dilution method, and we also have corresponding statements and test method documents as evidence. You are welcome to contact us at any time for further information.

Questions About Usage Guide

1. How to use the product? What is the recommended addition amount?

By scenario, the addition amount in daily skincare products (such as serums and face creams) should be less than 2%, while the addition amount in professional care products for beauty salons can range from 6% to 14% (Note: Relevant report materials for this data are available).

The product can be added to face creams and serums for daily skincare use,or mixed with serums as a core raw material for use in beauty salons.


2. What is the appropriate timing for adding hydrolyzed sponge (in cream and gel formulas)?

To ensure microneedle activity and dispersion effect, we recommend the following timings for adding hydrolyzed sponge in different formulas:

Serums and Gels:Add after uniform dispersion in the water phase.

Cream:Add at the final stage of production after complete emulsification.

Masks:Add directly to the gel base and stir evenly.

Following this timing will maximize the retention of microneedle efficacy. If you encounter any adaptation issues, please feel free to communicate with us at any time.


3. Will your Hydrolyzed Sponge penetrate the dermis?

The length of our Hydrolyzed Sponge ranges from 200 to 320 μm, and the depth of the epidermis is approximately 200 μm. Our Hydrolyzed Sponge can penetrate the epidermis and reach the dermis directly—avoiding being too shallow (only acting on the epidermis, which is ineffective) and too deep (penetrating the dermis, which increases risks). They can efficiently assist active ingredients in breaking through the skin's surface barrier, ensuring that these ingredients act on the skin stably and in sufficient quantities. At the same time, they activate the skin's repair mechanism, promote collagen regeneration, and achieve therapeutic effects. They can also effectively prevent skin damage or discomfort, making them suitable for various scenarios such as daily skincare and professional care.

4. I want to develop whitening products—how should I design the formula?

Hydrolyzed sponge itself does not directly provide whitening effects. Its core function is to create mild penetration channels on the skin's surface, helping subsequent ingredients penetrate more efficiently. To achieve whitening effects, additional whitening active ingredients need to be added to the formula, such as common and mild whitening ingredients like niacinamide, vitamin C, arbutin, and glabridin.


5. What are the main application scopes of hydrolyzed sponge?

Can it be added to scalp care products? Hydrolyzed sponge has a wide range of applications, and it currently focuses on the field of skincare products. In skincare, it can be added to serums, face creams, masks, and other products to help improve the skin's absorption efficiency. In the field of scalp care, it also supports addition to corresponding products, offering new possibilities for scalp care.


6. What happens to the hydrolyzed sponge powder left on the skin?

The hydrolyzed sponge powder will not remain on the skin and will not cause additional burden or irritation to the skin during this period. There is no need to worry or deliberately clean it off—it will be naturally excreted with the skin's normal metabolism after 2 to 3 days, fully following the skin's own metabolic rules.

7. What causes itching and redness after using hydrolyzed sponge?

Itching and redness after using hydrolyzed sponge are usually normal reactions. They mainly occur because Hydrolyzed Sponge slightly stimulate the skin barrier when creating absorption channels on the skin's surface, leading to a temporary redness or itching sensation. This typically eases gradually as the skin repairs itself. During this period, it is recommended to focus on moisturizing and sun protection: moisturizing helps soothe the skin and repair the barrier, while sun protection prevents ultraviolet rays from exacerbating irritation.


8. What are the precautions for handling hydrolyzed sponge?

The core precautions for handling hydrolyzed sponge are as follows: It is strictly forbidden to ingest, avoid inhaling, and take strict measures to prevent it from entering the eyes. Wear a mask if necessary; if it enters the eyes, do not rub—rinse immediately with a large amount of clean water. If discomfort occurs, seek medical attention promptly. When storing, seal the product and place it in a cool, dry place, away from children and pets.


Questions About Certification and Logistics

1. Domestic companies in China are concerned about market access issues—can hydrolyzed sponge meet compliance requirements?

There is no need to worry about the market access of hydrolyzed sponge, as the compliance of our products is clearly guaranteed:

① According to the relevant Q&A released by the Guangzhou Municipal Administration for Market Regulation in December 2023, the content of the 72nd issue in December 2024 has been updated, with the term "hydrolyzed sponge" removed. The updated definition standard states that a product will not be defined as a cosmetic only if it advertises "microneedle" or "microcrystal" characteristics and clearly states that the product is "not applied to the skin surface".

② The *Information on the Use of Raw Materials in Marketed Products* issued by the National Medical Products Administration in February 2025 still lists hydrolyzed sponge as an available raw material, and the official reply in June 2025 further emphasizes the definition boundary of cosmetics.

③ The product meets the requirements for domestic cosmetic raw materials. Currently, a variety of cosmetics containing this raw material have been launched on the market after completing the filing process, which can be queried on the Cosmetics Supervision APP of the National Medical Products Administration—confirming the compliance of its application.

④We provide complete Annex 14, raw material safety assessment reports, quality inspection reports, and other filing documents to help enterprises quickly complete product filing.

 If you need examples of market-launched products or filing support, please feel free to communicate with us at any time.


2:Do "microcrystal" or "hydrolyzed sponge" products fall within the definition of cosmetics?

A: According to the Regulations on the Supervision and Administration of Cosmetics, cosmetics refer to daily chemical industrial products used on the human surface, such as the skin, hair, nails, and oral cavity. For products claiming to be "microcrystal" or "microneedle", if they are comprehensively determined to be not applied to the human surface based on factors such as their formula, usage method, and product content form, such products exceed the scope of the definition of cosmetics in the Regulations on the Supervision and Administration of Cosmetics.
