Polymers
Polymers are long-chain molecules, an essential part of many formulas, playing different roles such as pH adjustment, viscosity control, sensory profile, etc. Some natural polymers can form a protective network covering the skin, guarding against UV exposure, pollution, and transdermal water loss. Others have mechanical lifting properties, allowing instantly lift and firm the skin's surface and exposing exceptional results.
Depending on requirements, polymers can also thicken, stabilize, emulsify, and texturize formulations, so those functional ingredients found their unique niche in the cosmetic industry.
