Looking to elevate beauty formulations with an innovative ingredient?
Spicules could be the perfect solution. These tiny, needle-like structures are making waves in the beauty industry, offering non-invasive, natural solutions for skincare. Derived from marine sponges or synthesized in labs, spicules enhance active ingredient delivery and promote skin renewal. Let’s explore the power of spicules and how they’re reshaping skincare.
What are Spicules?
Spicules are microscopic, needle-like structures that are found in marine organisms such as sponges. These tiny structures have garnered significant attention in various industries, especially skincare, for their unique ability to create micro-channels within the skin. These channels facilitate deeper penetration of active ingredients into the dermis, enhancing their efficacy and enabling visibly transformative results.
Spicules are often labelled as “hydrolyzed sponge” or simply “sponge” in ingredient lists. The composition of spicules varies, with many made from calcium carbonate (CaCO₃) or silica (SiO₂). Sourced sustainably from marine environments, spicules offer an eco-conscious, ethically produced solution that aligns with the increasing demand for sustainable skincare.
Types of Spicules in Beauty Formulations
The classification of spicules is essential for determining their utility in various industries. They are categorized based on material composition:
1. Calcareous Spicules
These spicules are made from calcium carbonate (CaCO3) and are often sourced from marine organisms like sponges and corals. Calcareous spicules are known for their lightweight, biodegradable, and non-toxic nature, making them an excellent choice for eco-friendly skincare products.
Key properties:
-
-
Gentle Exfoliation: Their crystalline structure allows them to exfoliate gently without harming the skin.
-
Eco-Friendly: Biodegradable and non-toxic, making them a sustainable choice.
-
Natural Skin Renewal: Their needle-like form helps remove dead skin cells and stimulate the production of new skin cells.
-
2. Siliceous Spicules
Composed of silica (SiO2), siliceous spicules are stronger and more durable than their calcareous counterparts. These spicules are effective for deeper exfoliation, helping to break down the outermost layer of skin to improve product absorption. They also stimulate collagen production by activating fibroblasts, the skin’s collagen-producing cells.
Key Properties:
-
-
Strength and Durability: Siliceous spicules are more rigid and durable, making them suitable for deeper exfoliation or applications requiring a firmer ingredient.
-
Enhanced Texture: They improve the texture and performance of formulations, making them highly effective in advanced skincare.

How Spicules Work on Skin
Spicules work through a combination of exfoliation, penetration and stimulation in a single ingredient.
- Natural Exfoliation: Spicules create a gentle micro-exfoliating effect, removing dead skin cells and improving texture.
- Penetration: Their needle-like structure allows active ingredients to penetrate the epidermis and reach deeper skin layers. This facilitates the absorption of key ingredients, ensuring they are more effective and can target deeper skin concerns.
- Stimulation: When spicules are applied to the skin, they help stimulate microcirculation and encourage collagen production. This process supports skin renewal and enhances the overall appearance of the skin by increasing elasticity and firmness.
This combination makes spicules an ideal ingredient for addressing concerns such as aging, pigmentation, and acne.

Applications of Spicules in Beauty Products
- Anti-Aging Products
The spicules stimulate collagen synthesis and improve elasticity, reducing the appearance of fine lines and wrinkles.
For E.g. OxygenCeuticals Spicule Regentox. This anti-wrinkle treatment utilizes spicules to promote skin remodeling and firmness. The spicules aid in delivering active ingredients deeper into the skin, enhancing their efficacy in combating signs of aging.
- Brightening Solutions
By enhancing the delivery of brightening agents like vitamin C and niacinamide, spicules help even out skin tone and reduce dark spots.
For E.g. Pestlo Spicule Reborn Peeling Mask. This mask contains spicules combined with green tea and mugwort extracts. The spicules facilitate the penetration of brightening ingredients, promoting a more radiant and even complexion.
- Acne and Skin Renewal
Their exfoliating and stimulating properties make spicules effective in clearing clogged pores and fading post-acne marks.
For E.g. 9wishes Pine Perfect Ampule Serum. Infused with spicules and extracts from pine leaves, licorice roots, and green tea, this serum targets acne-prone skin. The spicules aid in exfoliation and enhance the delivery of anti-inflammatory ingredients to reduce blemishes and promote skin renewal. 
- Professional Spa Treatments
Spicules are often incorporated into masks, peels, and other professional-grade treatments to deliver noticeable results in a single session.
For E.g. Pong Dang Professional Concentrate Spicule Cream. Designed for professional use, this concentrated cream utilizes spicules to exfoliate and rejuvenate the skin. It is applied in spa settings to provide clients with immediate improvements in skin texture and tone.
- At-Home Microneedling Alternative
With the rise of at-home skincare, spicules are becoming popular in serums, ampoules, and masks for professional-level results.
For E.g. VT Reedle Shot 100 Essence. This essence combines spicules with cica and propolis to offer intensive skin care at home. The spicules enhance the absorption of active ingredients, providing effects similar to professional treatments. 
Benefits of Spicules in Beauty Formulations
- Enhanced Active Ingredient Absorption
Spicules act like tiny, natural micro-needles. They create tiny channels in the skin, helping active ingredients like vitamins, peptides, or anti-aging compounds penetrate deeper into the deeper layers of the skin. This means the ingredients can work more effectively and give faster, visible results.
- Non-Invasive Alternative
Spicules mimic microneedling by creating micro-channels in the skin, enhancing active ingredient absorption without needles or pain. With no downtime or professional assistance needed, they are perfect for daily skincare. This gentle alternative delivers visible results with ease
- Eco-Friendly
Marine spicules are natural and biodegradable, meaning they break down safely in the environment without leaving harmful waste. This aligns with the growing trend toward clean beauty, where consumers are looking for sustainable, eco-friendly products. Spicules provide a way to get great skincare results without harming the planet.
- Versatile Applications
Spicules are flexible and is compatible with various ingredients. Their versatility makes them an ideal ingredient in formulations aimed at a variety of skin types and conditions, making them a valuable asset for skincare brands targeting diverse customer needs.
- Innovative Appeal
With their unique properties, spicules stand out in the skincare industry. Their ability to deliver visible results and enhance the effectiveness of skincare products makes them a sought-after ingredient for consumers interested in cutting-edge beauty solutions.

Challenges in Formulating with Spicules
While spicules offer numerous advantages, there are certain challenges to consider:
- Formulation Stability: Spicules need to remain effective across a range of product types, whether water or oil-based. This would require careful formulation to ensure they retain their beneficial properties in different product bases.
- Consumer Education: Not all users may be familiar with how spicules work or their advantages. Brands need to communicate clearly, helping consumers understand their purpose and how they can improve the product performance. For instance, consumers should be aware that spicules can take up to 72 hours to fully dissolve, causing a prickling sensation if they touch their skin during this time.
- Regulatory Standards: Spicules must meet regulatory safety and quality standards to ensure they are suitable for cosmetic use. This includes confirming they do not cause irritation and are responsibly sourced, which is vital for meeting global cosmetic safety regulations.
