Title

This module introduces the role of silicone in scar care, focusing on timing, indication, and realistic expectations. It provides a structured framework for understanding when silicone is appropriate, how it functions, and how to support patient adherence over time.
 
Silicone is widely used in scar management, yet confusion often exists regarding initiation timing, duration, formulation selection, and expected outcomes. This module addresses these questions through a practical, biologically informed approach.

Overview

Silicone therapy is commonly introduced following wound closure as a preventative or early-intervention strategy. Its use spans surgical scars, traumatic wounds, burns, and other forms of dermal injury.

 

Understanding when to begin silicone, how long to continue therapy, and how to monitor response requires familiarity with the biological phases of healing. Early overuse, delayed initiation, or unrealistic expectations can compromise patient confidence and perceived outcomes.

 

This module emphasises:

 

• Appropriate timing relative to epithelialisation

• Differences between gel and sheet formulations

• Duration frameworks aligned with scar maturation

• Communication strategies for setting expectations

 

Biological Context

Scar formation progresses through overlapping phases:
 
• Inflammatory phase
• Proliferative phase
• Remodelling phase
 
Silicone is typically introduced after full epithelialisation, during the early proliferative phase. Its proposed mechanisms include occlusion, hydration modulation, and regulation of collagen production within the scar environment.
 
Clinical improvement is gradual and dependent on consistent use over weeks to months.

Indications for Silicone Use

Silicone may be considered in the following situations:

• Post-surgical incisions
• Traumatic lacerations
• Burns following re-epithelialisation
• Patients with known risk factors for hypertrophic scarring
• Early signs of thickening or erythema

It is not indicated on open wounds or areas without complete epithelial closure.

Formulation Considerations

Two primary silicone formats are commonly used:
 
Silicone Gel
 
• Suitable for facial or highly visible areas
• Flexible and cosmetically discreet
• Requires daily application and drying time
• Appropriate for irregular surfaces
 
Silicone Sheets
 
• Provide consistent occlusion
• Reusable (depending on manufacturer guidance)
• Often preferred for flat surfaces
• Require consistent contact time

Selection should consider anatomical location, patient lifestyle, and likelihood of adherence.

Duration and Monitoring

Typical use spans several months, depending on scar behaviour.
 
General guidance:
 
• Begin after full epithelialisation
• Apply consistently as directed
• Monitor for reduction in redness, thickness, and firmness
• Continue through early remodelling phase
 
Reassessment is recommended if:

• Scar thickening progresses
• Pain or pruritus increases
• No observable improvement after consistent use

Patient Communication

Effective silicone therapy depends heavily on adherence.
 
Clinicians should clarify:
 
• Improvement is gradual
• Consistency is essential
• Results vary between individuals
• Silicone supports modulation — it does not erase scars
 
Clear communication reduces premature discontinuation.

Common Misconceptions

• Silicone does not “remove” scars
• Immediate results should not be expected
• Over-application does not accelerate outcomes
• Duration matters more than intensity
