Spicules are microscopic, needle-shaped structures that form the skeletal framework of marine sponges and certain types of coral. These naturally occurring micro-structures have been used in Eastern Asian and Russian skincare traditions for centuries, and in recent years they've become one of the most talked-about innovations in professional aesthetics.

In their natural state, spicules are composed of 100% hydrolyzed sponge: a single, clean ingredient. When massaged into the skin, they create a micro-channeling effect that allows them to act as a trans-epidermal delivery system. As they embed into the epidermis, they trigger a natural histamine response that draws oxygen-rich blood to the surface, creating a powerful oxygenating effect.

As the spicules gradually dissolve over the following days, they release a natural complex of vitamins, minerals, and bioactive compounds that stimulate collagen production, normalize melanocyte activity, and improve overall cellular health. This process typically accelerates epidermal turnover to approximately three days (compared to the skin's natural 28-day cycle).
