Materials of Oil Absorbing Sheets & Why Blotting Paper Turns Transparent | OEM Facial Blotting Sheets ESHA

Oil absorbing sheets, also widely called facial blotting sheets, are lightweight daily skincare supplies specially made to remove excess facial shine and sebum. Many users wonder about their raw materials and why the paper turns transparent after use, which we explain in detail below.

What Are Oil Absorbing Sheets Made Of?

Oil absorbing sheets are manufactured from thin highly absorbent substrates, the most common base materials being natural paper and soft synthetic fiber fabrics. To boost oil-trapping efficiency, many formulas add functional ingredients such as activated charcoal or natural clay powder inside the sheet layers. Eco-friendly product lines adopt plant-based raw materials, including natural hemp fiber and bamboo fiber, which deliver soft touch and strong oil absorption while being biodegradable.

Why Do Oil Absorbing Sheets Turn Clear After Use?

The transparent change comes from the core functional design of blotting sheets, which is to draw out surplus oil and sebum covering the skin surface. When pressed against oily skin, the absorbent fiber matrix quickly pulls sebum off the face and locks it inside the sheet. The more oil the sheet soaks up, the more transparent it becomes.This absorption process relies on capillary action — a physical phenomenon where liquid flows into tiny narrow gaps inside fibers without relying on gravity or extra external force. When facial oil touches the blotting sheet, capillary force guides oil into micro gaps between countless fine fibers. The process keeps running until the sheet reaches its maximum oil holding capacity.The sheet turns clear because oil is fully stored inside fiber gaps instead of lingering on the paper’s outer surface, so oily marks are no longer visible on the sheet exterior. That’s why these products are named blotting sheets — they instantly blot away surface oil for matte skin.To sum up: Oil absorbing sheets rely on capillary action of absorbent fibers to capture skin sebum deep inside the material. As oil fills the fiber gaps, the sheet gradually becomes transparent with no oily residue showing on the surface.
