Silicone Scar Gel for Surgery and Injury Scars: Evidence-Based Options for Australian Women

December 3, 2025

Quick Summary:

Silicone gel is a clinically studied topical treatment that may help flatten, soften, and fade surgical and injury scars over 8-12 weeks of consistent use. Research suggests silicone creates a protective barrier that maintains skin hydration and appears to regulate collagen production. While individual results vary significantly, silicone-based products remain the most widely recommended first-line option for scar management by dermatologists worldwide.

Why Scars Become More Visible After 40

As women enter their 40s and beyond, skin changes associated with hormonal shifts can make scars more noticeable and slower to heal. Declining oestrogen levels reduce collagen production and skin elasticity, which affects how your body repairs tissue after surgery or injury.

The same surgical scar you might have barely noticed at 30 can become more raised, discoloured, or textured after menopause. This isn't just about ageing—it's about how hormonal changes affect your skin's healing capacity and overall tissue quality.

Understanding How Scars Form and Why They Don't Fade on Their Own

When your skin experiences trauma from surgery, injury, or burns, your body initiates a complex healing process. During the inflammatory phase, white blood cells rush to protect the wound. Next, collagen production ramps up to rebuild tissue. Finally, the scar continues to mature and remodel for up to two years.

The problem occurs when collagen production becomes disorganised or excessive. This results in raised, thickened, or discoloured scars that remain visible despite the wound being completely healed.

Without intervention, many scars remain prominent indefinitely. The natural remodelling process can improve appearance slightly, but significant fading typically requires consistent treatment starting early in the healing process.

What the Research Actually Says About Silicone Gel for Scars

Silicone has been studied for scar management since the 1980s, with research published in journals including Burns, Plastic and Reconstructive Surgery, and Journal of Korean Medical Science.

Studies suggest that silicone gel may reduce scar height by approximately 37-68%, improve colour by around 84%, and enhance texture by roughly 86% in some patients. However, it's crucial to understand these are average results from controlled studies—individual responses vary considerably.

A 2020 meta-analysis in International Wound Journal found that silicone gel products showed statistically significant improvement in Vancouver Scar Scale scores at 6 months post-surgery, but effects were less pronounced at 3 months. This indicates patience is essential for meaningful results.

The mechanism appears to involve maintaining optimal skin hydration, which may influence how fibroblasts (cells that produce collagen) function during healing.

Types of Scars That May Respond to Silicone Gel Treatment

Research suggests silicone gel can be applied to various scar types, though effectiveness varies:

Surgical scars from procedures like breast surgery, abdominal operations, or joint replacements often show improvement with early, consistent application.

Caesarean section scars may flatten and fade with twice-daily use over several months.

Keloid and hypertrophic scars (raised, thickened scars) appear to respond to silicone, though results are typically less dramatic than with newer scars.

Burn scars have been included in multiple research studies, with some showing positive outcomes.

Acne scars may show modest improvement, though deeper atrophic scars generally require professional treatments.

Most research indicates that younger, immature scars (those still red or raised) respond better than scars older than one year.

What to Look for in a Medical-Grade Silicone Gel

Not all silicone products are created equally. When evaluating options, consider these research-backed features:

Medical-grade silicone concentration ensures the product creates an effective occlusive barrier
Additional evidence-based ingredients like peptides or probiotics may support skin health during healing
Self-drying formula that forms an invisible layer allows for normal daily activities
Hypoallergenic formulation reduces risk of irritation during the vulnerable healing period
Airless packaging maintains ingredient stability and prevents contamination

Generic silicone products may not meet the same manufacturing standards as purpose-designed scar treatment gels developed for medical-grade applications.

Genova Silicone Scar Gel: An Australian Evidence-Based Option

For Australian women looking for a local option, Genova Silicone Scar Gel combines medical-grade silicone with two additional active ingredients: Vanistryl (a peptide that may help improve elasticity) and Ecoskin Probiotic (designed to support skin's microbiome during healing).

The product is manufactured in Queensland and contains ingredients selected based on published research on scar healing. The gel is designed to be applied twice daily to clean, dry skin once the wound is fully closed and stitches have been removed.

While Genova positions itself as a comprehensive scar treatment, it's important to understand what it can and cannot do (see limitations below).

How to Use Silicone Gel Properly for Best Results

Proper application technique influences outcomes significantly:

Step 1: Wait until your wound is completely healed, stitches removed, and no scabbing remains (typically 2-4 weeks post-surgery). Consult your doctor before starting any scar treatment.

Step 2: Clean the scar area with mild soap and water, then pat completely dry.

Step 3: Apply a thin layer of silicone gel directly to the scar tissue, rubbing gently for 2-3 minutes.

Step 4: Allow 4-5 minutes for the gel to fully dry before dressing or applying makeup.

Step 5: Repeat twice daily, morning and evening, for a minimum of 8-12 weeks. Many patients continue for 3-6 months for optimal results.

A small amount of silicone may remain visible on the skin surface—this is intentional and creates the protective barrier necessary for effectiveness.

Realistic Expectations: What Silicone Gel Can and Cannot Do

Potential benefits with consistent use:

May flatten raised scars by creating optimal healing environment
Can help soften rough, rigid scar tissue over time
Appears to reduce redness and discolouration in many users
May decrease itching and discomfort associated with healing scars
Works on various body locations including face, chest, and joints

Limitations to understand upfront:

Results typically require 8-12 weeks minimum, not instant improvement
Old, mature scars (over 1 year) show limited response in research
Individual variation means some people see minimal change
Deep atrophic scars or severe keloids may need professional treatments
Silicone gel cannot completely eliminate scars or restore skin to pre-injury state
Effectiveness depends heavily on consistent twice-daily application

Silicone gel is a supportive treatment, not a guarantee. Managing expectations based on your specific scar type, age, and skin condition is essential.

Additional Factors That Influence Scar Healing

While silicone gel may support scar improvement, other factors play crucial roles:

Sun protection is non-negotiable. UV exposure darkens scars and makes them more visible. Apply SPF 50+ daily and reapply every two hours when outdoors.

Nutrition affects healing capacity. Adequate protein, vitamin C, vitamin E, and zinc support tissue repair. Consider whether your diet provides these consistently.

Hydration maintains skin elasticity during the healing process. Aim for adequate water intake daily.

Avoiding smoking is critical, as tobacco impairs blood flow and delays wound healing significantly.

Adequate sleep allows your body to focus energy on tissue repair and regeneration.

When to Consider Professional Scar Treatment Instead

Some scars require more intensive intervention than topical products can provide. Consider consulting a dermatologist or plastic surgeon if:

Your scar is severely raised, rope-like, or growing beyond original wound boundaries (keloid)
Silicone gel shows no improvement after 3-4 months of consistent use
The scar restricts movement or causes functional limitations
You experience ongoing pain, itching, or discomfort despite treatment
The scar significantly impacts your confidence or daily life

Professional options like laser therapy, steroid injections, or surgical revision may be more appropriate for severe scarring.

Frequently Asked Questions About Silicone Gel for Scars

When should I start using silicone gel after surgery?

Start once the wound is completely healed, stitches removed, and no scabbing remains—typically 2-4 weeks post-surgery. Always confirm with your surgeon first.

How long does it take to see results?

Most research shows improvement becomes noticeable around 6-8 weeks with twice-daily use. Optimal results typically require 3-6 months of consistent application.

Can I use silicone gel on old scars?

You can try, but research indicates mature scars (over 1 year old) respond less effectively than newer scars. Results will likely be modest at best.

Is silicone gel safe during pregnancy or breastfeeding?

Generally considered safe as topical silicone has minimal systemic absorption, but always check with your healthcare provider before using any product during pregnancy or breastfeeding.

Can I apply makeup over silicone gel?

Yes, once the gel is fully dry (4-5 minutes), you can apply makeup, sunscreen, or other skincare products over it.

Making an Informed Decision About Scar Treatment

Choosing a scar treatment requires weighing your specific circumstances: scar type, age of scar, location, your commitment level, and budget.

Silicone gel represents an evidence-based first-line option supported by decades of research. It won't work miracles, but for many people dealing with surgical or injury scars, consistent use over several months can lead to noticeable improvement in appearance and texture.

If you're considering Genova Silicone Scar Gel specifically, its combination of medical-grade silicone with additional active ingredients may offer comprehensive support for scar healing. However, realistic expectations and patience are essential—no topical product can completely erase established scars.
