Why Light Convex Makes a Difference

Not all stomas sit the same way. If yours is flush with your skin or slightly retracted rather than protruding, a flat baseplate may not create the seal you need—output can pool around the stoma or leak under the barrier. Light convex baseplates provide gentle pressure that encourages your stoma to protrude slightly, creating better contact with the barrier and a more reliable seal. The "light" convexity offers this support without the firm pressure of full convex options, making it ideal for soft abdomens or mild retraction. Combined with Mio Flex's elastic adhesive that adapts to your body contours, you get the support you need with everyday comfort.

Perfect for: Flush or slightly retracted stomas on soft abdomens, mild stoma retraction, individuals needing gentle convex support without rigid pressure, or those transitioning from flat to convex barriers.

What You'll Appreciate

Gentle support that works — Light convexity provides just enough pressure to encourage your stoma to protrude without the discomfort of firm convex baseplates. If you have a soft abdomen or only mild retraction, this is often the perfect balance.

Better sealing, fewer leaks — When your stoma protrudes slightly into the barrier opening, output flows directly into the pouch instead of pooling around the stoma base. This creates a more reliable seal and reduces the risk of undermining leaks.

Flexible comfort — The adhesive coupling and elastic adhesive technology mean this baseplate moves with your body instead of creating rigid pressure points. Bend, sit, or move through your day—the barrier adapts to you.

Slim, discreet profile — No bulky plastic ring means the baseplate lies flatter against your body. The slim design is more comfortable and less noticeable under clothing than traditional two-piece systems.

Adapts to your contours — The elastic adhesive responds to your body shape and movement, helping prevent edge lift even on curved or uneven areas. This is especially helpful if standard flat barriers have given you edge lift issues.

Custom fit confidence — The cut-to-fit opening lets you trim the exact size you need, ensuring the convex curve sits properly around your stoma for optimal pressure and seal.

How to Use

Preparation:

1. Measure your stoma in the morning when sizing is most consistent
2. Assess your skin — ensure the peristomal area is clean, dry, and healthy
3. Have your pouch ready — you'll apply it immediately after the baseplate

Cutting and Application:

1. Mark the opening:
   • Place the baseplate face-down on a clean surface
   • Use the cutting guide to mark your stoma size (typically 1-2mm larger than actual stoma)
   • Mark 15-40mm to match your measurements
2. Cut the opening:
   • Use sharp scissors designed for barrier cutting
   • Cut smoothly in one continuous motion for a clean edge
   • The opening should be round to match your stoma shape
3. Prepare the baseplate:
   • Remove the protective backing paper
   • Warm the baseplate briefly in your hands (improves adhesion and flexibility)
4. Apply to skin:
   • Center carefully — the convex curve should surround your stoma evenly
   • Press the center first to position correctly
   • Smooth outward from center in all directions, pressing firmly
   • Pay special attention to edges — the elastic adhesive needs good contact
   • Hold pressure for 30-60 seconds for secure initial adhesion
5. Attach your pouch:
   • Align the pouch's adhesive coupling with the baseplate's 50mm coupling
   • Press firmly and evenly around the entire coupling circumference
   • You should hear/feel a secure connection all the way around

Important Tips for Light Convex:

• Positioning matters: Make sure the convex curve is centered on your stoma. Off-center application reduces effectiveness
• Don't force it: Light convex provides gentle pressure. If you need more pronounced convexity, you may need a standard or deep convex option
• Skin assessment: Check your peristomal skin regularly. The convex pressure should not cause redness, indentation, or irritation
• Body position: Apply while standing if possible, as this is how you'll wear it most of the time

Baseplate Wear Time:

• Typically 3-5 days for most users
• Change sooner if you notice edge lift, leakage, skin irritation, or adhesive loosening
• Some people can wear up to 7 days depending on output and skin condition

Pouch Changes: You can change pouches (drainable every 1-3 days, closed after each use) while keeping your light convex baseplate in place—one of the key benefits of a two-piece system.

Understanding Convexity Levels

When do you need convex support? Convex baseplates are designed for stomas that don't protrude adequately or sit in uneven areas. Here's how to understand the options:

Flat Baseplates:

• Best for: Stomas that protrude ½ inch or more; even, firm peristomal planes
• Characteristics: No curve; sits flush against skin
• When to use: Your stoma "sticks out" and you have no leakage issues with flat barriers

Light Convex (This Product):

• Best for: Flush or slightly retracted stomas; soft abdomens; mild stoma retraction
• Characteristics: Gentle curve; provides mild pressure
• When to use: Your stoma is level with or slightly below skin surface; soft abdomen tissue
• Pressure level: Gentle — comfortable for extended wear on soft tissue

Standard/Full Convex:

• Best for: Moderately retracted stomas; creases/folds near stoma; firmer abdomens
• Characteristics: More pronounced curve; provides moderate-to-firm pressure
• When to use: Significant retraction; deep skin folds; light convex hasn't provided enough support
• Pressure level: Moderate to firm — creates more pronounced protrusion

Deep Convex:

• Best for: Severely retracted stomas; very deep skin folds; challenging peristomal planes
• Characteristics: Deepest curve; provides maximum pressure
• When to use: Severe retraction; multiple failed fittings with lesser convexity
• Pressure level: Firm — requires clinical fitting and monitoring

How to Choose: Start with the least convexity that solves your problem. Light convex is ideal if you have mild retraction or flush stoma but don't want the pressure of full convex. Your ostomy nurse can help determine the right level.

Comparison: Light Convex vs Flat Mio Flex

Light Convex Mio Flex (This Product):

• Gentle pressure for stoma protrusion
• Best for flush/slightly retracted stomas
• Suitable for soft abdomens
• Helps prevent pooling around stoma base
• May provide better seal if flat barriers leak

Flat Mio Flex:

• No convex curve or pressure
• Best for protruding stomas
• Suitable for any abdomen firmness
• More comfortable if you don't need convexity
• First choice for most new ostomates with good stoma protrusion

Which should you choose?

• Stoma protrudes ½ inch or more → Start with Flat
• Stoma is flush with skin → Try Light Convex
• Stoma retracts below skin level → Need Light or Standard Convex
• Not sure? → Consult your ostomy nurse for proper fitting

Can you switch between them? Yes, both use the same 50mm Mio Flex coupling, so you can use the same pouches with either baseplate type. This lets you experiment to find what works best.

Troubleshooting Light Convex Use

"How do I know if light convex is right for me?" Light convex is appropriate if:

• Your stoma sits flush with your skin or slightly below
• You have a soft abdomen
• Flat baseplates leak or allow output to pool around the stoma
• You don't have deep retraction or severe skin folds Your ostomy nurse can assess your stoma and recommend the right convexity level.

"The baseplate feels uncomfortable or creates pressure." This could mean:

• The convexity level is too strong for your needs (try flat instead)
• The opening is cut too small (creating excess pressure on the stoma)
• Your abdomen is very soft and sensitive (may need to build tolerance gradually) Consult your ostomy nurse if discomfort persists—convex barriers should provide support without pain.

"I'm still getting leaks even with light convex." Possible solutions:

• Verify the opening is cut correctly (not too large)
• Check that you're centering the baseplate properly when applying
• You may need standard convex for more pronounced pressure
• Consider adding barrier accessories (paste, rings) for additional support
• Have your ostomy nurse reassess your needs

"How much skin pressure is normal?" Light convex should create gentle, even pressure that's noticeable but comfortable. You should not see:

• Deep indentations in your skin
• Redness that doesn't fade within 30 minutes of removal
• Bruising or skin breakdown
• Pain during normal wear If you experience any of these, the convexity may be too firm for your needs.

"Can I use a belt with light convex?" Some light convex baseplates have belt tabs. A belt can provide additional support, but use it carefully—you don't want to over-compress the area. Your ostomy nurse can show you proper belt tension.
