Karaya-based barriers are particularly good for which skin type?

• A. Sensitive skin
• B. Extremely oily skin
• C. Thick, calloused skin
• D. Infected skin

Answer: (A)

Karaya-based barriers are chosen for their gentle, skin-friendly adhesion. Karaya gum creates a soft, cushiony seal that swells with moisture to hug the skin without sticking too aggressively. This means less pulling and less friction during application and removal, which protects delicate, irritated, or sensitive peristomal skin from trauma. The barrier also conforms well to uneven skin contours and helps manage moisture to reduce maceration, which is especially important when the skin is fragile or reactive.

That’s why they’re the best fit for sensitive skin. In other skin cases, such as very oily skin, thick or calloused skin, or infected skin, other barrier types may be more appropriate because they require stronger adhesion, different texture, or drainage considerations.
