The Maybelline Lasting Fix Loose Powder is a cosmetic product primarily composed of talc, silica, and dimethicone. Talc, a naturally occurring mineral composed of magnesium, silicon, and oxygen, serves as a light-diffusing agent in the powder, imparting a smooth and matte finish to the skin. Silica, a mineral derived from silicon dioxide, acts as an oil-absorbing agent, helping to reduce shine and provide a long-lasting matte effect on the skin. Dimethicone, a silicone-based polymer, functions as a skin protectant and emollient in the formulation, forming a barrier on the skin's surface to lock in moisture and improve the overall texture of the skin. These active ingredients work synergistically to control excess oil production, minimize the appearance of pores, and enhance the longevity of makeup application. The pH of the Maybelline Lasting Fix Loose Powder is neutral, falling within the range of 6.5-7.5, making it suitable for a wide range of skin types. The viscosity of the product is moderate, allowing for easy application and blending on the skin. Due to the finely milled particles of talc and silica, the powder has high absorption properties, effectively absorbing excess sebum on the skin and preventing a greasy or shiny complexion. The bioavailability of the ingredients in the Maybelline Lasting Fix Loose Powder is primarily limited to their topical application on the skin.
