Pearl powder is made from freshwater pearls or saltwater pearls below jewellery grade. These are sterilised in boiling water and then milled into a fine powder using stainless steel grinding discs or by milling with small porcelain balls in moist conditions. The powder is sold as such or mixed into creams. Pearl powder is widely believed to help improve the appearance of the skin, and is used as a cosmetic by royal families in Asia. It is also used as a treatment for acne. Some studies have claimed that pearl powder can stimulate the skin's fibroblasts, help regenerate collagen, and accelerate healing of certain skin conditions, wounds, and burns. This book seeks to introduce the benefits of pearl powders and to highlight the potential of this advanced material.
