Blotting paper is a special type of absorbent paper used primarily for soaking up excess ink or moisture. It is commonly used in writing and art to prevent smudging and to help dry ink quickly. The paper is typically thicker and more porous than regular paper, allowing it to absorb liquids effectively. In addition to its use in writing, blotting paper is also popular in cosmetics. It can be used to remove excess oil from the skin, helping to maintain a matte appearance. Many people carry blotting paper in their bags for quick touch-ups throughout the day.
