What it is
Dextrin is a polysaccharide produced by the partial breakdown of starch, commonly from corn, tapioca, or potato. In cosmetic products it can absorb excess oil to give a softer, less greasy feel, act as a binder, and help adjust the body of a formula. In sunscreens it is often used to refine skin feel and contribute a smoother, more matte finish.
Safety & warnings
Dextrin is a well-established, food-grade carbohydrate that is generally well tolerated on skin, with a low expectation of irritation or sensitization. It is not considered comedogenic.
Origin & sourcing
It is derived from plant starch, such as corn, tapioca, or potato, through controlled hydrolysis.
