Convex Skin Barriers – Brief Description:

Convex skin barriers are ostomy products designed with a raised, outward curve (convexity) to help create a secure seal around a stoma, especially for individuals with flush, retracted, or irregular stomas. The convex shape gently pushes against the skin around the stoma, encouraging it to protrude for better drainage into the pouch, reducing leakage and improving wear time.

They come in different levels of convexity (light, medium, deep) and may be available in pre-cut, cut-to-fit, or moldable styles.

Major Manufacturers:

Coloplast – SenSura Mio Convex and Assura Convex Barrier Lines.
Convatec – Esteem+ and SUR-FIT Natura Moldable and Convex Barriers.
Marlen Manufacturing – UltraLite Convex and UltraMax Convex Skin Barriers.
B. Braun – Flexima 3S Convex Barriers.

Convex skin barriers are specialized adhesive wafers used in ostomy care to achieve a more secure, comfortable, and leak-resistant fit, especially for individuals with challenging stoma or abdominal profiles. Unlike flat skin barriers, convex barriers feature a gentle outward curve that applies light pressure around the stoma to improve protrusion and enhance the seal even during extended wear.

At ATC Medical, we offer a wide selection of convex skin barriers designed to provide a secure, leak-resistant fit and greater confidence for ostomy patients. Our range includes multiple depths and configurations to accommodate flush, retracted, or irregular stomas, helping users maintain comfort, protection, and independence every day.

How Convex Skin Barriers Work

The curved shape of a convex barrier exerts a supportive pressure on the peristomal skin (the area around the stoma). This pressure encourages the stoma to extend slightly outward, helping direct output into the ostomy pouch instead of under the adhesive. The result is a tighter, more reliable seal that reduces leakage and skin irritation.

Convexity is particularly useful for patients whose stoma is:

  • Flush or Retracted: When the stoma does not extend above the skin surface.
  • Surrounded by Folds or Creases: The convex barrier fills in dips or soft skin areas, maintaining a consistent seal.
  • Prone to Output Leakage or Poor Adhesion: The added pressure improves wear time and confidence.

When to Choose a Convex Barrier

A convex skin barrier may be recommended by a WOC (Wound, Ostomy, and Continence) nurse or healthcare professional if you experience:

  • Persistent leakage under a standard skin barrier
  • Short wear time due to poor adhesion
  • An irregularly shaped or recessed stoma
  • Difficulty achieving a snug, comfortable fit with flat barriers

Available Convex Skin Barrier/Wafer Options

Convex skin barriers are available in different depths of convexity to suit individual needs and stoma types, including light, medium, or deep. They come in both one-piece and two-piece ostomy pouching systems and can be combined with accessories such as barrier rings or strips for added protection.

Key Benefits of Convex Wafers

Convex skin barriers offer a reliable solution for those who need extra support to achieve a leak-free, comfortable fit, helping protect the skin and simplify the management of their pouching system every day.

  • Provides a more secure seal for the ostomy or urostomy pouch on uneven or soft abdomens
