Microneedles in Cosmetics: What Are Spicules and Why Are They So Popular?

You apply a serum to your face, but instead of the usual feeling of hydration, you notice a tingling sensation. Your first thought: “Did something go wrong?” 👀 If the formula contains spicules, this sensation may be related to the product's specific properties.

Spicules have become one of the trends in K-beauty. Cosmetics containing them are often referred to as liquid microneedling. It sounds almost like a professional beauty treatment, but instead of a special device, you have a product sitting on your beauty shelf.

But do at-home microneedles really work like professional microneedling? What do they do to the skin, and who should be especially careful when using them?

Let's find out together 😉

What Are Spicules and How Do They Work?

Spicules are tiny needle-shaped particles that mechanically interact with the skin. They are most commonly derived from marine or freshwater sponges.

The size, shape, and composition of spicules can vary depending on their origin and production method. For example, some consist primarily of silicon dioxide, a mineral substance that gives them their hardness.

In cosmetic ingredient lists (INCI), sponge-derived ingredients may be listed as Hydrolyzed Sponge. However, this name alone does not indicate the size or number of spicules in a product or predict how the skin will react to its application.

And what do the numbers on the packaging mean? 👀 You may have noticed labels such as 50, 100, or 300 on products containing spicules. Depending on the brand, these numbers may indicate the number of spicules or the product's intensity level. Generally, a higher number means a more intensive effect within the same product line.

However, each manufacturer may use its own labeling system, so comparing numbers across different brands is not accurate ☝️

What Happens After Application?

When you apply a product to your face, spicules mechanically interact with the skin. Depending on the particle size and product formula, they may affect the superficial layers of the skin and temporarily alter the permeability of its protective barrier.

This particular feature has attracted attention to spicules in K-beauty. They are often combined with other active ingredients, as researchers explore their potential to improve the penetration of these ingredients into the skin.

During or after application, you may experience a mild tingling sensation. Its intensity and duration vary from person to person and depend on the product's characteristics and your skin's sensitivity.

💡 Beauty fact: stronger tingling does not mean better results. The most important thing is that your skin feels comfortable!

What Makes Spicules Interesting in Cosmetics?

Spicules have attracted attention in the beauty world because of their unusual way of interacting with the skin and their potential to be combined with various active ingredients.

But what can you actually expect from cosmetics containing microneedles? Let's take a closer look! 💗

1. Combination with Active Ingredients

Serums and creams containing spicules often include niacinamide, peptides, hyaluronic acid, and other popular ingredients. Spicules may temporarily affect the permeability of the skin barrier, which is why they are being studied as a potential way to improve the penetration of active ingredients. The complete product formula and the properties of the individual ingredients play an important role.

2. Care for Uneven Skin Texture

Cosmetics containing spicules are often developed for skin with uneven texture, visible pores, and post-acne marks.

These products may be designed to help maintain a smoother and more even-looking complexion. However, the results depend on the complete formula, and the effectiveness of spicules themselves for these concerns still requires further research.

3. Convenient Format for At-Home Skincare

Another reason for the popularity of spicules is their ease of use. No special devices or tools are needed: simply choose a ready-to-use cosmetic product and follow the instructions. But remember: cosmetics containing spicules do not replace professional microneedling, as these treatments affect the skin differently.

💕 Ksisters tip: want to try cosmetics containing spicules? Focus on your skin's needs rather than the numbers on the packaging. After all, higher intensity does not necessarily mean better results!

Spicules: What Should You Know Before Using Them?

Cosmetics containing spicules may cause unusual sensations. That's why it's important to understand how your skin might react to this type of care.

• Tingling. May occur during or after application. Its intensity varies from person to person and does not indicate the product's effectiveness.
• Redness, dryness, and flaking. These may sometimes occur after use, but they do not mean that the skin is renewing itself faster.
• Sun protection. If a product irritates the skin or affects its protective barrier, it is especially important to avoid excessive sun exposure and use SPF regularly.

💡 Important: intense burning, itching, swelling, or prolonged redness are reasons to stop using the product. Beauty should never come at the cost of discomfort!

The frequency of use depends on the specific product. Some formulas are designed for more frequent application, while others are intended for occasional care.

That's why you should always follow the manufacturer's recommendations and monitor your skin's reaction.

If you have sensitive skin, introduce the product gradually. Performing a patch test on a small area beforehand may help identify an unwanted reaction.

Who Should Be Especially Careful?

Spicules may be uncomfortable for skin with increased sensitivity or a weakened protective barrier 🤍

When is it better to avoid using them?

• If your skin is damaged, irritated, or has active inflammation.
• While your skin is recovering from chemical peels, laser treatments, or other procedures that affect its barrier.

If you have rosacea, pronounced sensitivity, or other dermatological conditions, consult a dermatologist before use.

Also, don't rush to combine spicules with retinoids, strong acids, or other potentially irritating active ingredients. First, give your skin time to adjust to the new product.

How to Add Spicules to Your Beauty Routine

Want to get to know microneedles a little better? Start by choosing a product format that feels comfortable for you 🥰

What types of products contain spicules?

Serums and boosters. A popular format in which spicules are often combined with additional skincare ingredients.

Creams. Have a creamy base but are not necessarily gentler than serums.

Masks. An additional skincare option that should be used according to the instructions.

Scalp ampoules. Special formulas containing spicules designed for scalp care.

Don't focus solely on the product name or intensity label. The complete ingredient list, intended use, and individual skin tolerance are what matter.

And to make choosing the right format easier, we've put together a selection of cosmetics containing spicules. Explore different textures and choose skincare that suits your skin's needs 🌱

How to Apply Cosmetics Containing Spicules Correctly

For leave-on products, the general routine may look like this:

1. Cleansing. Wash your face with a gentle cleanser and carefully pat it dry with a towel.
2. Applying the spicule product. Distribute the recommended amount without rubbing it in vigorously, provided this follows the product instructions.
3. Moisturizing. If recommended by the manufacturer, finish your routine with a comfortable moisturizing cream.

Avoid applying the product to your eyelids, lips, or damaged areas unless it is specifically intended for use on these areas.

💡 Beauty tip: don't introduce several new active ingredients at once. This will make it easier to understand how your skin reacts to each product.

Spicules vs. Dermaroller: What's the Difference?

Because of the term liquid microneedling, it may seem that cosmetics containing spicules work in the same way as a dermaroller. But that's not quite true!

A dermaroller is a tool with needles of a specific length that mechanically puncture the skin. The depth of their effect depends on the needle length and application technique.

Spicules are microscopic needle-shaped particles found in cosmetic formulas. Their effects depend on the characteristics of the particles and the product's formulation.

The risks are also different. Spicules may cause irritation, while using a dermaroller additionally carries a risk of skin injury and infection, especially if proper hygiene practices are not followed.

A separate recovery period is not always necessary after using cosmetics containing spicules, whereas recovery after microneedling may take longer.

The key takeaway: spicules are not a “dermaroller in a jar,” so you shouldn't expect identical results from these two skincare approaches 😌

Conclusion: Are Spicules Worth Trying?

If you're concerned about uneven skin texture, visible pores, or post-acne marks, cosmetics containing spicules may be worth exploring. This is an interesting area of K-beauty skincare, where microneedles are combined with other active ingredients in formulas designed to help maintain a smoother and more even-looking complexion.

At the same time, the effectiveness of spicules themselves for these concerns still requires further research, so the results depend on the complete product formula and your skin's individual characteristics.

Want to give them a try? Choose a product according to your skin's needs, follow the instructions, and introduce it gradually into your beauty routine. After all, the most important thing is that skincare brings you not only enjoyment but also comfort! ✨🫰🏻
