How to Crust Using Stoma Powder and Skin Barrier

Crusting is a technique using stoma powder and barrier film to protect open skin beneath the ostomy pouch.

Step 1: Clean and dry the skin near the stoma. 

  • Wash with water. Then let it dry. 

  • Don’t use baby wipes, foam soap, lotions, or alcohol near the stoma.

Step 2: Apply stoma powder

  • Sprinkle a little powder on any raw and wet skin. 

  • Brush or tap off the extra powder. 

  • The powder should only stay on open areas – not on healthy skin.

Step 3: Apply the barrier film. 

  • For barrier film pad, gently dab over the powder to seal. 

  • For barrier film spray, lightly spray the whole area.

Step 4: Let it dry. 

  • If it dries, a white crust will form. 

  • If the skin is still wet, you can repeat one more time. 

  • If there’s too much crusting, the pouch may not seal.

Step 5: Apply the pouch.

  • Once the crust is dry, put on the pouch system.  

  • When the skin heals, you may stop crusting.
