Korean beauty (K-beauty) has recently popularized the term 'spicules,' which refers to microscopic, needle-like structures derived from marine sponges. These structures have become a key ingredient in various skincare products, touted for their potential to enhance the delivery of other ingredients and improve skin texture, radiance, and the appearance of pores. Dr. Ahmed El Muntasar, a GP and aesthetics doctor, explains that applying products containing spicules may create a tingling sensation as they interact with the skin's surface, thereby stimulating it physically.

While spicules are gaining traction, Dr. Ahmed cautions that some marketing claims equating them with professional treatments like microneedling may not yet be fully substantiated by research. The growing interest in spicules aligns with a consumer desire for products that provide immediate, noticeable effects during application.
Social media has played a significant role in popularizing spicules, with products labeled as 'needle shots' or 'liquid microneedling' making these once niche ingredients more accessible. Dr. Ahmed notes, however, that it's advisable for users to gradually introduce spicule-containing products into their routines, starting with lower concentrations to assess their skin's reaction. He recommends maintaining a simple skincare regimen and avoiding the concurrent use of strong active ingredients until the skin adapts.
Spicules may be particularly beneficial for individuals with resilient skin looking to address issues such as dullness or large pores. Caution is advised for those with sensitive skin or conditions like eczema or rosacea, who should avoid using spicules near active skin irritation or immediately after certain procedures.
The frequency of use for spicule products can vary based on their concentration and formulation. Dr. Ahmed suggests starting with use once or twice a week, increasing only if the skin tolerates it well. Signs of irritation, such as redness and burning, should prompt users to cease application instead of pushing forward.
Looking to the future, Dr. Ahmed believes spicules are likely to remain a relevant ingredient in skincare, driven by trends in Korean beauty and high-performance home care products. However, he emphasizes the importance of further clinical research to verify their efficacy and the true benefits they provide. As the excitement around spicules continues, the conversation may evolve to focus more on substantiated claims rather than bold marketing.
