Silicone scar gel works gradually, not overnight. This guide explains how to tell if silicone scar gel is working with RejûvaSil Silicone Scar Gel, what to compare at 4, 8, and 12 weeks, and when to ask a clinician about a scar that is not improving.
- How to tell if silicone scar gel is working: compare baseline photos at 4, 8, and 12 weeks.
- Track scar color, height, texture, and symptoms in matching light rather than judging one day at a time.
- RejûvaSil Silicone Scar Gel is a daily gel option; sheets suit scars where longer contact is practical.
- Ask a clinician about a painful, growing, open, infected, or motion-limiting scar.
Why this matters
Most people quit silicone scar gel between week 3 and week 6 because nothing looks different yet, and that's the exact window where the scar is still remodeling under the surface. Silicone therapy doesn't dissolve scar tissue overnight — it hydrates the outer layer, reduces the collagen overproduction that causes raised, red scars, and gradually flattens and softens tissue over months, not days.
Judging "is this working" by a glance in the mirror on day 10 sets you up to abandon a product that would have worked with 6 more weeks of consistent use. The fix is knowing what markers to track, on what schedule, and what a real plateau actually looks like versus normal week-to-week variation.
What you'll need
- A silicone scar gel or silicone sheeting product, such as RejûvaSil Silicone Scar Gel or Scar Esthetique Scar Cream
- A phone camera for photo tracking
- Consistent, indoor, same-angle lighting for photos
- A soft measuring tape or ruler (for width/height tracking on raised scars)
- A calendar or notes app to log application dates
- 8 to 12 weeks minimum before drawing conclusions
The steps
1. Photograph the scar before you start
This is the step almost everyone skips, and it's the one that actually proves whether silicone scar gel is working. Take a photo on day one, in the same lighting, same distance, same angle you'll repeat every time.
Without a baseline photo, your brain will normalize gradual change and you won't notice real progress. Use a ruler or coin in frame for scale. Expected outcome: a clear reference point you'll compare against at week 4, week 8, and week 12.
Common mistake: taking the first photo weeks into treatment because "it wasn't that bad at first." By then you've lost your true starting point.
2. Apply on a consistent schedule
Silicone gel needs to stay on the scar for extended periods to hydrate the stratum corneum and signal the tissue to stop overproducing collagen. Most silicone gel products are designed for twice-daily application, with silicone sheeting worn 12 or more hours a day.
Inconsistent use is the number one reason people think silicone scar gel isn't working when the real issue is the routine. Set two daily reminders and treat it like a prescription, not an occasional touch-up.
Expected outcome: a scar that stays visibly hydrated rather than dry and tight between applications. Common mistake: applying once a day and expecting twice-daily results.
3. Check texture at the two-week mark
Texture change comes before color change for most scars. At week 2, run a clean finger over the scar and compare it to your mental note from day one — is it less raised, less rope-like, softer to the touch?
This is a subtle check, not a dramatic one. Expected outcome: a change you can document, not a day-to-day impression. Common mistake: treating normal variation in color or firmness as proof that the treatment has worked or failed.
4. Compare photos at week 4
Pull up your day-one photo next to a new one taken the same way. Look specifically at scar width, raised height, and shine (silicone-treated scars often look slightly glossy from hydration, which is normal).
If the scar looks identical in every dimension at week 4, that's not a failure yet — it's still within the normal window. Expected outcome: early, subtle softening in most cases; flat scars may show faster color fading. Common mistake: panicking at week 4 and switching products before the therapy has had time to work.
5. Reassess color and redness at week 8
By week 8 of consistent use, most users start seeing a real shift in redness, especially on newer scars from surgery or injury within the past year. Older scars — one year or more — move slower and need the full 12-week window before you judge results.
Hold your day-one photo next to a fresh one in identical lighting. Expected outcome: noticeably less pink or purple tone, and a scar that blends closer to surrounding skin. Common mistake: comparing photos taken in different lighting, which makes color changes impossible to judge accurately.
6. Measure raised height at week 12
For hypertrophic or keloid-type scars, height is the metric that matters most. Use a ruler or the flat edge of a card to check how far the scar rises above the surrounding skin compared to your baseline note.
A measurable drop in height by week 12 is the clearest sign silicone scar gel is working. Expected outcome: a scar that sits flatter against the skin, even if some raised texture remains. Common mistake: measuring on a day the scar is irritated or freshly applied, which can temporarily swell tissue and skew the reading.
7. Decide: continue, switch, or combine
If your week-12 photos and measurements show flattening, fading, or softening, keep going — full results for stubborn hypertrophic scars can take 3 to 6 months. If nothing has changed at all across three separate check-ins, the issue is usually wear time, not the silicone itself.
Switching from gel to sheeting, or combining both, can make sense when a gel will not stay in place or a clinician recommends longer contact. RejûvaSil Silicone Scar Gel is suited to newer scars in areas where a sheet is hard to wear; silicone sheeting is practical when secure, longer coverage is realistic.
Troubleshooting
- No change after 12 weeks, but you've been consistent — the scar may be over a year old and thicker than average; extend the timeline to 4-6 months before switching products.
- Gel rubs off during the day — switch to silicone sheeting, which stays adhered through clothing and movement better than gel on high-friction areas.
- Skin around the scar looks irritated — reduce wear time temporarily and confirm the product is fragrance-free; irritation is not the same as the therapy "not working."
- Scar looks shiny or slightly white after application — this is expected hydration from the silicone layer, not a bad sign.
- You can't tell if it's the product or just natural healing — this is exactly why the baseline photo from day one matters; without it, you're guessing.
- Photos look inconsistent between checks — standardize your lighting source and distance every single time, ideally near a window at the same time of day.

FAQ
How long does it take to see results from silicone scar gel?
Most people see visible texture change by week 2 to 4 and color change by week 8, with fuller results at 12 weeks. Thicker hypertrophic scars can take 3 to 6 months of consistent daily use.
Is silicone scar gel or silicone sheeting better?
Silicone sheeting generally delivers longer, uninterrupted contact time and works better on thicker or hypertrophic scars, while gel is more convenient for daily wear on visible or mobile areas. Many routines combine both.
What does it mean if silicone scar gel isn't working?
In most cases it means inconsistent wear time rather than a bad product — silicone needs 12+ hours of daily contact to signal collagen changes. Check your application schedule before switching products.
How often should I apply silicone scar gel?
Most silicone gel products are designed for twice-daily application, morning and night, for consistent hydration and coverage. Skipping applications extends the timeline before you'll see change.
Can silicone scar gel fade old, healed scars?
Yes, but older scars respond slower than fresh ones and may need 4 to 6 months of consistent use to show meaningful fading. Try Rejuvaskin Scar Esthetique for older scars. Newer scars, especially those under a year old, tend to respond faster to gel and sheets..
Does silicone scar gel work on keloid scars?
Silicone therapy is commonly used to help manage keloid and hypertrophic scar texture and height, though results vary by scar age and thickness. A combined sheeting-and-gel routine over several months tends to show the most measurable change.
How do I know if a scar has stopped improving?
If photos and height measurements show no change across three separate check-ins spaced weeks apart, the scar has likely plateaued on the current routine. That's the point to reassess wear time or switch to sheeting. Remember, plastic surgeons often tell patients it takes 12 months to 18 months for a scar to completely heal
Should I use sunscreen while treating a scar with silicone gel?
Yes — UV exposure can darken healing scar tissue and undo silicone progress, especially on scars less than a year old. Cover treated areas or apply mineral sunscreen once the silicone layer has dried.
One last thing
Silicone products belong on fully closed skin, not an open wound. If a scar is painful, rapidly enlarging, draining, infected, or restricting movement, contact the clinician managing your care rather than extending at-home treatment.
