Bio microneedling, also known as sponge spicules, are natural substances derived from freshwater sponges. These are tiny biological needles that freshwater sponges have evolved over time to adapt to their environment.

The main application of sponge micro-needles is in the field of beauty and skincare. The principle behind it is to use these tiny needle-like spicules to penetrate the stratum corneum of the skin, stimulate the skin to promote the shedding of dead skin cells, absorb and remove clogged pores, and thus improve conditions such as acne pits and scars. Sponge micro-needles can create millions of skin absorption channels in a very short time, helping active ingredients to penetrate the skin and improve issues like dark circles and fine lines around the eyes.
