Cosmetic-grade pearl powder, also known as pearl extract, pearl protein powder, or nano-pearl powder, is a luxurious skincare ingredient derived from finely ground pearls. Its key active ingredients—calcium carbonate, over 18 amino acids, including glycine and taurine, trace minerals (magnesium, selenium, zinc), and conchiolin (pearl protein)—have been used for centuries for their brightening, anti-aging, and skin-repairing properties.
High-purity nano-sized pearl powder (40-100 nanometers) boasts superior absorption and efficacy. We specialize in providing ultra-fine pharmaceutical-grade pearl powder with a purity exceeding 99%, processed using cryogenic grinding technology to preserve the integrity of its bioactive components. Made only from natural freshwater pearls without shell waste or synthetic fillers.
Containing >99% natural freshwater pearl content, we source only premium pearls, ensuring higher concentrations of conchiolin (5-8%) and over 18 amino acids. Zero chemical bleaching preserves biological activity. Annual production capacity exceeds 300 tons with strict quality consistency.
Customized particle size (1,000-10,000 mesh) allows for double the depth of skin penetration. Cryogenic grinding prevents thermal degradation of peptides. It can increase hyaluronic acid absorption by 30% and vitamin C stability by 10% in complex formulations.

Rich in amino acids and minerals, it helps promote collagen production and enhance skin elasticity, reducing fine lines and wrinkles.
Known for melanin-regulating properties, it is used to brighten dull skin and even out skin tone over time.
Natural anti-inflammatory properties help soothe irritation, reduce redness, and promote skin recovery.
Provides a luminous finish in foundations and setting powders without clogging pores, creating a soft-focus effect.
Note: Actual dosage depends on formulation type and regional regulatory restrictions.
Simply disperse it into the aqueous phase of a cream, lotion, or serum. For homemade face masks, you can mix it with hydrosols, yogurt, or honey. Using micronized powder promotes better absorption.
2. How does cosmetic-grade pearl powder differ from food-grade?Cosmetic-grade is ultra-refined and micronized for topical use, ensuring a smoother texture and reduced skin irritation. It meets stricter particle size requirements for skin penetration.
3. Can pearl powder be combined with other anti-aging ingredients?Yes! It pairs well with niacinamide, hyaluronic acid, collagen peptides, and botanical extracts to enhance overall anti-aging effects.
4. Is pearl powder suitable for sensitive skin?Generally, yes. Pearl powder has natural anti-inflammatory and calming properties that can help soothe sensitive or irritated skin, but a patch test is always recommended for new formulations.
5. Does your pearl powder contain synthetic fillers?No, our pearl powder is made from 100% natural freshwater pearls. We do not use shell waste, chemical bleaches, or synthetic fillers in our processing.
6. What is the shelf life of the powder?When stored in a cool, dry place away from direct sunlight, the shelf life is typically 24-36 months. Always ensure the container is tightly sealed after use.
