Do Silicone Scar Gels Actually Work? What the Evidence Shows
Quick summary
Yes, silicone scar gels work, and they are the most evidence-backed at-home scar option. Dermatologists and plastic surgeons recommend silicone as a first-line treatment for raised and red scars. Research shows consistent use can improve a scar's texture, colour and height over a few months. It will not remove a scar or work overnight, and results vary. Used twice daily with sun protection, silicone gel is the simplest evidence-based step for most healed scars.
Short answer: silicone scar gels are not hype. Silicone is the most studied topical scar treatment and a first-line recommendation from dermatologists and plastic surgeons, especially for raised and red scars. It will not remove a scar, but the evidence that it improves how a scar looks and feels is solid. Here is what the research actually shows.
Do silicone scar gels actually work?
They do. Decades of clinical use and published reviews support silicone as an effective, low-risk way to manage scars. Major reviews and clinical guidelines list silicone gel and sheets as a first-line, non-invasive option for hypertrophic (raised) scars and for reducing redness, hardness and discomfort.
What silicone does not do is magic. It cannot remove scar tissue, lift a deeply pitted acne scar, or replace medical treatment for a large keloid. What it can do, reliably for many people, is make a scar flatter, softer, less red and less noticeable over time.
How does silicone gel work on a scar?
Silicone is not a drug. It works physically. When you apply it, it dries into a thin, breathable layer over the scar that does two things:
- Locks in hydration. A well-hydrated scar produces less excess collagen, which is what makes scars raised and firm.
- Protects and calms the scar. The barrier shields the area and helps signal the scar to settle, easing redness and itch.
This is why a quality gel like the Genova Silicone Scar Gel dries clear and stays put. For the deeper mechanism, see the science behind silicone scar gel.

What does the research say silicone improves?
Clinical reviews of silicone scar treatment consistently report improvement across the features that make a scar stand out. The table sums up what the evidence points to.
| Scar feature | What research suggests silicone can do |
|---|---|
| Height (raised scars) | Helps flatten raised, hypertrophic scars over months |
| Colour and redness | Helps fade redness and even out discolouration |
| Texture and firmness | Softens hard scar tissue, improving flexibility |
| Itch and discomfort | Eases the itch and tightness common in healing scars |
The studies are clear on one thing: results depend on consistency. Silicone only works if it is used daily over months, which is where most people fall short.
Is silicone gel better than other scar treatments?
For at-home care, silicone has the strongest evidence base of the common options. Oils and vitamin E are popular but far less supported. Here is how it compares, with the detailed head-to-heads linked:
- Versus silicone sheets: similar active, different format. Gel suits the face, joints and visible areas. See gel versus sheets.
- Versus scar tape: tape adds tension support; gel is simpler for daily wear. See gel versus tape.
- Versus Bio-Oil and vitamin E: these mainly moisturise. The evidence for fading scars is much weaker. See Bio-Oil versus silicone and vitamin E versus silicone.
How to get results from silicone scar gel
The evidence only pays off if you use it properly:
- Wait until the wound is fully healed with no open skin or scab.
- Apply a thin layer twice a day and let it dry clear.
- Add SPF over the top each morning; sun undoes the work.
- Keep going for 8 to 12 weeks, with fuller results over 3 to 6 months.

Realistic expectations: Silicone gel improves how a scar looks and feels. It cannot remove a scar, flatten a deeply sunken acne scar, or treat a large keloid on its own. Results build over months and vary from person to person. For a scar that is growing, painful or changing, see a doctor.
Who silicone scar gel is for (and who it is not for)
Worth using if you: have a healed surgical, C-section, injury or acne scar, want a drug-free daily step, and are realistic about gradual change.
Less suited if you: have an open wound, a large or growing keloid that needs medical care, or expect a scar to vanish completely.
Frequently asked questions
Do silicone scar gels really work, or is it marketing?
They genuinely work. Silicone is a first-line, dermatologist-recommended scar treatment with decades of clinical support for improving scar texture, colour and height. It is not a cure, but it is the best-evidenced at-home option.
How long before silicone gel shows results?
Most people see a softer, less red, flatter scar within 8 to 12 weeks of twice-daily use, with fuller results over 3 to 6 months. Stopping early is the main reason people see nothing.
Does silicone gel work on old scars?
It can. Old scars respond more slowly than fresh ones, but consistent use plus sun protection can still improve texture and colour over several months.
Is silicone gel or silicone sheeting more effective?
Both use the same principle and both work. Gel is easier on the face, joints and visible areas; sheets suit flat, coverable spots. Consistency matters more than the format.
Can silicone gel make a scar worse?
No. Silicone is gentle and suitable for all skin types. The main risk is wasted effort from stopping too soon or applying to unhealed skin.
