Sponge spicules are a kind of siliceous bio microneedle that are extracted from the freshwater sponge. They can stimulate the dermis of the skin and start skin surface microcirculation. They effectively deliver active ingredients to the dermis layer of skin while also activating the basal skin cells.
They can be seen as powder to the naked eye and as a sharp rod crystal under the microscope. In just 5 Minutes, 3 – 5 000,000 natural siliceous microneedles are directly introduced into the dermis layer through hand massage
