Which of the following lists the main ingredients of the skin barrier?

• A. Hydrocolloid, Tackifiers, and Polymers
• B. Hydrocolloid alone
• C. Tackifiers alone
• D. Polymers alone

Answer: (A)

A skin barrier works because it combines three roles: moisture management, adhesion, and structural integrity. Hydrocolloid is the moisture-absorbing layer that protects the skin and helps form a seal around the stoma. Tackifiers modify the adhesive properties so the wafer sticks securely to peristomal skin and stays in place with movement. Polymers provide the backing and flexible matrix that give the barrier strength, tear resistance, and durable fit. Together, these components balance sticking power, moisture handling, and barrier durability. Using only one type would miss a critical function—for example, hydrocolloid alone manages moisture but may not adhere well; tackifiers alone won’t control moisture; polymers alone won’t provide proper adhesion.
