Spicules vs Microneedling

Posted by Sarah Kinsler-Holloway on

In the quest for achieving healthy and youthful skin, various skincare treatments have emerged. Two popular techniques that have gained attention in recent years are spicules and micro-needling. While both methods aim to rejuvenate the skin, they differ in terms of their mechanisms and the benefits they offer. Let's explore the differences between spicules and micro-needling, helping you make an informed decision about which treatment may be best for your clients.

Understanding Spicules

Spicules are microscopic needle-like structures derived from marine sponges. These naturally occurring elements are known for their regenerative and collagen-stimulating properties. Spicules are typically used in skincare products or in-office treatments, like the Green Sea Peel

  • Mechanism of Action: When applied to the skin, spicules penetrate the epidermis, creating tiny channels. These channels facilitate the absorption of active ingredients into the deeper layers of the skin, promoting collagen production and stimulating cellular regeneration.
  • Benefits: Spicules can improve skin texture, reduce the appearance of fine lines and wrinkles, enhance elasticity, and promote a more youthful complexion. They can also aid in the delivery of other beneficial ingredients, such as vitamins and antioxidants, into the skin.  Last, and maybe the most exciting benefit; they are pregnancy safe, and safe for all fitzpatricks

Exploring Microneedling

Microneedling, also known as collagen induction therapy, involves the use of a device equipped with numerous tiny needles. These needles create controlled micro-injuries in the skin, triggering the body's natural healing response and stimulating collagen production.

  • Mechanism of Action: During a microneedling session, the needles create microscopic punctures in the skin. This process activates the release of growth factors and stimulates collagen and elastin production. The micro-injuries also enhance the absorption of topical products, maximizing their effectiveness.

  • Benefits: Microneedling can improve skin texture and tone, reduce the appearance of acne scars, hyperpigmentation, and stretch marks, and minimize the signs of aging. It also enhances the penetration of skincare products, allowing them to work more efficiently.

Key Differences

  • Method: Spicules are natural needle-like structures derived from marine sponges, while microneedling involves the use of a device with multiple tiny needles.

  • Mechanism: Spicules create channels in the skin to enhance the absorption of active ingredients, while microneedling creates controlled micro-injuries to stimulate collagen production.

  • Applications: Spicules are often found in skincare products or utilized in professional treatments, while microneedling can be performed using a device.


Spicules offer an effective alternative for skin rejuvenation for estheticians who aren't able to micro-needle.
