Sponge microneedle are also called Sponge Spicule , diatom microneedles, water needles, biological microneedles, etc. Sponges are one of the simplest multicellular organisms that live in Marine or freshwater environments. They appear as powder to the naked eye and are pointed, rod-shaped, crystalline and blunt needles under a microscope. This kind of acicular crystal is a good impurity adsorbent, which can not only destroy the protein structure of microorganism or virus, The negative ion charge can also adsorb impurities or precipitate pigments in the solution. Freshwater sponges gradually evolved the special bone, that's spongilla spicules, which is a siliceous spicules, very small, but has a stronger hardness, for supporting the sponge body and resisting the enemy's invasion. Spongilla spicules constituted by hard protein and heteronuclear hard protein, do not dissolve in any kind of organic solution, therefore, can be used as a kind of ideal natural materials in cosmetics and skin peeling curing.

Product Name   Sponge microneedle   Appearance   White Powder   Assay 20% 40% 70% 99% Solubility Water Solube Test Method HPLC Certificate ISO 1.Sponge Spicule Microneedles penetrate into the stratum corneum and epidermis, enabling the skin to accelerate the absorption of water and nutrition 2.Sponge Spicule Deep into the hair follicle, adsorption and removal of clogged pores oil, quickly take away toxins and garbage can effectively deal with dark skin, anti-black after laser surgery, exfoliation, blackhead acne, skin inflammation, rough skin, folliculitis, seborrhea, skin pigmentation, sun damage and aging, skin rejuvenation, fine wrinkles, enlarged pores, acne, pus, dandruff, oil secretion (oil control), etc 3.Sponge Spicule can penetrate into the cuticle and epidermal layer through the acicular crystals of microcrystalline diatoms (about 250-300μm in length), start the epidermal skin microcirculation, and let the aging cuticle naturally peel off, to achieve natural, safe and effective physical skin rejuvenation 4.The natural exfoliation of aging keratin is conducive to the regeneration of the skin and the generation of new cells; 5. Stimulates collagen and elastin regeneration Hydrolyzed Sponge can improve the skin question fast and efficient, because of many tiny needles on micro needle, stimulate the skin, in a short time micro needle can be made more than millions of tiny pipe, make the active ingredient infiltrate into skineffectively, stimulate new cell regeneration to micro needle nutrients into the cell active substances. So as to reduce wrinkles, skin whitening, reduce color spots, improve eye wrinkles, dark circles, tighten and enhance the facial skin tissue and other ideal effects. At the same time, microneedle stimulation dermis, through the skin's self-healing ability, promote collagen proliferation. Our Service
