パウダーは、化粧品が肌に優しくないという問題をどのように改善できるのでしょうか？
With the popularity of makeup, powder usage in cosmetics is growing. Cosmetics powders fall into four main categories. These are pigment powders, white powders, filler powders, and pearlescent powders. Pigment powders are used to adjust cosmetic color tones. White powders provide coverage, whitening, and UV protection. Filler powders vary and serve multiple functional roles. They enhance spreadability, absorption, adhesion, and texture. They also reduce visual focus and carry active ingredients. Pearlescent powders add shine and improve product texture. Skin-feel enhancing powders are gaining attention across skincare, makeup, and sunscreen. They include inorganic, organic, and natural powders. Inorganic skin feel improving powder Silicon dioxide Silica powders, chemically known as silicon dioxide, […]
