Hypertrophic scars can flatten and fade with consistent home care, and most raised, red post-surgical or post-injury scars respond to silicone therapy without a prescription. The routine matters more than the product — timing, wear-time, and consistency drive the result in 2026.
- Silicone gel and sheeting, not massage or vitamin E, produce measurable flattening for hypertrophic scars in 2026.
- Start treatment within 2-4 weeks of full wound closure; a delayed start adds months to results.
- Wear silicone sheeting 12-23 hours daily for 60-90 days minimum before judging progress.
- Add a compression wrap for raised, thick scars that silicone alone isn't flattening.
- Skip vitamin E and onion-extract gels — clinical evidence for hypertrophic scars is thin.
Why this matters
A hypertrophic scar is raised tissue that stays within the original wound border, unlike a keloid, which spreads beyond it. Left alone, hypertrophic scars can stay thick and red for a year or more.
Medical-grade silicone is the only topical category with decades of published support for reducing thickness, redness, and itch in these scars. Everything else — cocoa butter, vitamin E oil, herbal gels — lacks that same evidence base. Getting the routine right in the first 6-8 weeks after a wound closes changes the outcome more than any single product choice.
What you'll need
- A fully closed wound with no open areas, scabbing, or drainage
- A silicone gel for daily application, such as RejûvaSil Silicone Scar Gel
- Silicone sheeting sized to the scar for pressure therapy
- Mild, fragrance-free cleanser and water
- A compression garment or wrap if the scar is on a joint, breast, or abdomen
- SPF 30 or higher mineral sunscreen for any scar exposed to daylight
- A phone camera to photograph the scar every 2-4 weeks
The steps
1. Confirm it's a hypertrophic scar, not a keloid
This determines which products and wear-times actually apply. Hypertrophic scars are raised but bounded by the original incision or wound line; keloids grow past that border and often need a dermatologist's involvement alongside home care.
Check the edges against the original wound shape. If the scar has grown wider or longer than the cut itself, treat it as a possible keloid and get it evaluated before committing to a 90-day home routine. Mistake to avoid: assuming any raised scar is a keloid — most raised post-surgical scars in 2026 are hypertrophic and respond well to silicone alone.
2. Wait for full wound closure before starting
Silicone products go on intact skin only. Applying gel or sheeting over an open wound risks infection and won't help the healing tissue underneath.
Wait until there's no scabbing, no drainage, and no open skin — typically 2-3 weeks after suture removal, longer for surgical incisions with deeper closure. Starting silicone within 2-4 weeks of that closure point produces better flattening than starting at 3 months. Expected outcome: skin that's pink, dry, and closed, ready for daily product. Common mistake: starting silicone too early and irritating fragile new tissue.
3. Clean and dry the scar twice daily
A clean surface lets silicone adhere and do its job; buildup of sweat, lotion, or debris breaks the seal and reduces effectiveness. Wash gently with a mild cleanser morning and night, pat dry completely — don't rub — and wait 5 minutes before applying anything else. Expected outcome: a dry, product-free surface each time you reapply. Mistake to avoid: applying gel over damp skin, which dilutes it and shortens wear time.
4. Apply silicone gel in a thin layer
Gel works by rehydrating the outer layer of scar tissue and regulating collagen production underneath — this is what reduces redness and thickness over weeks. Apply a rice-grain-sized amount and spread it thin enough to dry within 4-5 minutes; a thick layer stays tacky and picks up lint. Use it twice daily for at least 60 days before judging results. Expected outcome: a scar that feels less firm to the touch by week 4-6. Common mistake: applying too much gel, which just wastes product and doesn't speed results.
5. Switch to silicone sheeting for pressure therapy
Sheeting adds sustained pressure and occlusion that gel alone can't match, which matters most for thicker or larger scars. Cut a piece of Scar Fx silicone sheeting to fit the scar with a small margin of healthy skin on each side, then wear it 12-23 hours a day. Remove it to wash the sheet and your skin once daily. Expected outcome: visible flattening starting around week 8-12 of consistent wear. Common mistake: wearing sheeting only at night, which cuts total contact time roughly in half.
6. Add compression for thick or raised scars
Compression is the added mechanical pressure that sheeting alone sometimes can't deliver on curved or high-movement areas like joints, the chest, or the abdomen. A stretchable silicone compression wrap holds the sheet in place and adds gentle, even pressure through the day. Expected outcome: faster reduction in scar height on stubborn, thick scars over 8-12 weeks. Common mistake: wrapping too tight, which causes skin breakdown instead of flattening.
7. Protect the scar from UV exposure
New scar tissue has no melanin protection and darkens permanently if it's sunburned during the healing window, which can take 12-18 months to fully mature. Apply a mineral sunscreen of SPF 30 or higher any time the scar will see daylight, even through a car window. Expected outcome: a scar that fades to a lighter, less noticeable color as it matures. Common mistake: skipping sunscreen on cloudy days — UV still reaches skin.
8. Track progress at 4, 8, and 12 weeks
Scar tissue changes slowly, and without photos it's easy to miss real progress or keep using something that isn't working. Photograph the scar under the same lighting every 2-4 weeks and compare width, height, and color side by side. Expected outcome: a documented trend by week 12 that tells you whether to continue, adjust, or see a dermatologist. Common mistake: judging results after 2 weeks — silicone therapy needs 60-90 days minimum to show change.
“If the scar isn't flattening by week 8, the sheeting isn't being worn long enough.”
Troubleshooting
- Skin irritation or a rash under the sheet: Reduce wear time to 8-10 hours a day for the first week, then build back up. Check that the skin is fully dry before each application.
- Sheeting won't stay stuck: Trim the edges to round corners and wash the adhesive side with mild soap and water rather than alcohol, which strips the tack faster.
- Scar isn't flattening after 8 weeks: Confirm actual daily wear time — most stalled cases are wearing sheeting 6-8 hours instead of the recommended 12-23.
- Itching that won't settle: This is common in the first 2 weeks and usually eases as the skin adjusts; persistent itching past week 3 warrants a dermatologist check.
- Scar darkening despite treatment: This points to unprotected sun exposure, not a silicone failure — add SPF 30+ mineral sunscreen daily.
- White, soggy skin under the sheet (maceration): Cut wear time in half and let the skin fully dry between sessions; this resolves within days.

What to do next
Once the routine is running, the next decision is sizing sheeting correctly for the scar's exact dimensions rather than trimming a generic sheet by eye — a poor fit is the single biggest reason people stop seeing results after week 8. Read choosing the right silicone scar sheet size before ordering a second round of sheeting.
FAQ
What is the fastest way to treat hypertrophic scars at home in 2026?
Daily silicone gel plus 12-23 hours of silicone sheeting wear, started within 2-4 weeks of wound closure, is the fastest evidence-backed home approach. Most people see measurable flattening by week 8-12, not sooner.
Is silicone gel or silicone sheeting better for hypertrophic scars?
Sheeting provides more sustained pressure and works faster on thicker scars, while gel is easier to wear under clothing and on the face. Many routines use gel during the day and sheeting overnight, or sheeting full-time once the scar tolerates it.
How long does it take to flatten a hypertrophic scar?
Most hypertrophic scars show visible flattening after 60-90 days of consistent silicone therapy. Thicker or older scars can take 6-12 months of continued wear to fully mature and fade.
Can hypertrophic scars be treated without silicone?
Compression alone helps some scars, but silicone is the only topical category with strong published support for hypertrophic scars specifically. Vitamin E, onion extract, and cocoa butter have weak or inconsistent evidence.
Do I need a dermatologist for a hypertrophic scar?
Most hypertrophic scars respond to a disciplined home routine of silicone gel or sheeting without a specialist visit. See a dermatologist if the scar keeps growing past the original wound border, which suggests a keloid instead.
How much does hypertrophic scar treatment cost?
Over-the-counter silicone gel and sheeting kits typically run $30-$150 depending on scar size and whether a compression wrap is added. That's well below in-office laser or steroid injection treatments, which run into the hundreds per session.
Is it too late to treat an old hypertrophic scar?
Silicone therapy still helps older scars, though results are slower than on a fresh scar started within weeks of wound closure. Expect 3-6 months of consistent wear before judging whether an older scar is responding.
Should I wear sunscreen on a healing scar?
Yes — new scar tissue has no melanin protection and can darken permanently if sunburned during its 12-18 month maturation window. A mineral SPF 30+ sunscreen applied daily prevents that outcome.
One last thing
Wear-time, not product choice, is the variable that separates a flattened scar at 12 weeks from a stalled one. People who track actual hours of sheeting contact almost always find they're under the 12-hour minimum, and closing that gap alone often restarts progress without changing a single product.
