An existing keloid scar doesn't shrink on its own, and picking the wrong first move can make it grow. This guide walks through the at-home steps that actually change the trajectory of an existing keloid scar in 2026, plus the point where you stop DIY-ing and call a dermatologist.
- Silicone gel and sheeting are the first-line home approach for how to treat an existing keloid scar — start daily use now.
- Keloids need 8-12 weeks of consistent silicone therapy before you can judge results; quitting at week 3 wastes the effort.
- Sun exposure darkens keloid tissue permanently, so daily mineral SPF over the scar is non-negotiable, not optional.
- A keloid that keeps expanding after 12 weeks of silicone therapy needs a dermatologist and a corticosteroid injection, not a stronger cream.
- Surgery alone on a keloid has a high recurrence rate; pairing removal with silicone therapy afterward is standard practice.
Why This Matters
A keloid is not the same thing as a hypertrophic scar, and the difference changes your treatment plan. Hypertrophic scars stay within the original wound border and often flatten over a year or two on their own. Keloids grow past the original incision or injury site and, left alone, can keep expanding for years.
Keloids show up most often on the ears, chest, shoulders, and jawline, and they're more common in people with darker skin tones. None of that means an existing keloid scar is untreatable — it means the plan has to be consistent, not aggressive. Rushing to laser or excision without a maintenance plan is one of the most common reasons keloids come back bigger.
What You'll Need
- A silicone-based gel for daily application — Rejuvasil silicone scar gel is formulated for scars that have already formed, not just fresh wounds
- Silicone sheeting cut to the size of the keloid, worn 12-24 hours a day
- A gentle, fragrance-free cleanser to prep the skin before each application
- A mineral sunscreen for the scar site, since UV exposure darkens keloid tissue
- Patience — a realistic 8-12 week trial period before you evaluate whether the routine is working
- A dermatologist's contact information, in case the keloid doesn't respond and needs a clinical intervention
The Steps
1. Confirm it's actually a keloid
A raised scar that stays inside the original wound line is hypertrophic. A raised scar that spreads beyond the original cut, piercing, or injury is a keloid. This distinction matters because hypertrophic scars often respond faster to silicone alone, while keloids typically need a longer commitment and, sometimes, a combination of home care and in-office treatment.
Common mistake: treating every raised scar the same way and giving up on silicone therapy too early because a hypertrophic-scar timeline was expected.
2. Clean the area and apply silicone gel twice daily
Wash the keloid and surrounding skin with a mild cleanser, pat dry completely, then apply a thin layer of silicone gel. Let it dry for 3-5 minutes before covering with clothing or sheeting. Morning and night is the standard schedule; skipping applications resets the clock on visible change.
Common mistake: applying a thick layer. A thin, evenly spread coat absorbs faster and doesn't transfer onto clothing.
3. Layer silicone sheeting over the gel for extended wear
Cut a silicone sheet slightly larger than the keloid, clean the sheet with mild soap and water after each wear, and reapply for 12-24 hours daily. This combination — gel plus sheeting — is the core of Rejûvaskin's Scar Heal Kit approach: hydration and occlusion working together instead of either product alone.
Common mistake: wearing the sheet only at night. Daytime wear under clothing (not visible skin) adds hours of therapy without disrupting your routine.
4. Protect the scar from sun exposure every single day
UV light darkens keloid tissue and can make the discoloration harder to reverse later. Apply mineral sunscreen over the area whenever it's exposed, and reapply after sweating or swimming. This step gets skipped constantly because keloids are often in covered areas — but ears, chest, and shoulders see plenty of sun in summer 2026.
Common mistake: assuming a scar that's usually covered doesn't need SPF. One unprotected beach day can undo weeks of fading progress.
5. Try Rejûvaskin's silicone scar cream if sheeting isn't practical
Keloids on curved or hard-to-cover areas — like the tragus of the ear or a shoulder joint — don't always hold a sheet well. In that case, a silicone scar cream applied 2-3 times daily delivers similar occlusive benefits without needing tape or adhesive.
Common mistake: switching products every two weeks looking for faster results. Consistency with one silicone-based routine outperforms constant switching.
6. Track the keloid at the 8-12 week mark
Take a photo on day one, then again every two weeks under the same lighting. At 8-12 weeks of consistent silicone therapy, evaluate: is the keloid softer, flatter, or less discolored? If yes, keep going — full remodeling of scar tissue takes months, not weeks. If the keloid is unchanged or growing, that's your signal to escalate.
Common mistake: judging results at week two and abandoning a routine that needed 8-12 weeks to show anything.
7. Escalate to a dermatologist if silicone alone isn't enough
An existing keloid scar that keeps growing despite consistent silicone therapy usually needs a clinical intervention: corticosteroid injections, cryotherapy, or laser treatment are the common next steps a dermatologist will discuss. Surgical excision is sometimes recommended, but excision alone carries a high recurrence risk — most dermatologists pair surgery with silicone therapy or steroid injections afterward to reduce regrowth.
Common mistake: going straight to surgery without a post-procedure silicone plan already in place.
Troubleshooting
- The silicone sheet won't stay stuck. Clean and dry the skin fully before each application, trim the sheet closer to the scar's actual size, and reserve adhesive edging for high-movement areas like joints.
- Redness or irritation develops under the sheeting. Cut wear time to 6-8 hours for a few days, switch to gel-only application, and reintroduce sheeting gradually once the skin calms down.
- No visible change after 4-5 weeks. This is normal — silicone therapy on an existing keloid scar typically needs 8-12 weeks minimum before remodeling is visible. Keep the routine going before judging it.
- The keloid keeps growing despite consistent use. Silicone therapy manages and softens existing keloid tissue; it doesn't guarantee shrinkage on its own. A dermatologist consult for a corticosteroid injection is the next step.
- Itching or stinging after applying gel or sheeting. Patch test a small area for 24 hours before resuming full coverage, and stop use if irritation persists past a few days.
- The scar darkens instead of fading. Check sun exposure first — even brief unprotected exposure re-pigments keloid tissue faster than silicone therapy can fade it.

What To Do Next
If the keloid formed after a recent surgery or procedure and hasn't fully matured yet, the approach shifts slightly toward prevention alongside treatment — read preventing keloid scars after surgery for the early-intervention version of this routine.
FAQ
How do you treat an existing keloid scar at home?
Daily silicone gel combined with 12-24 hours of silicone sheet wear is the standard home approach for an existing keloid scar. Give the routine 8-12 weeks before judging results, and add daily sun protection over the scar.
Can silicone gel shrink a keloid that's already formed?
Silicone gel can soften, flatten, and reduce discoloration in existing keloid tissue over consistent use, though full shrinkage varies by scar size and age. Keloids that don't respond after 8-12 weeks usually need a dermatologist's injection or in-office treatment.
Is silicone sheeting better than silicone gel for keloids?
Sheeting and gel work through the same occlusive mechanism, so neither is universally better — sheeting suits flat surfaces worn under clothing, while gel suits curved areas like ear keloids that won't hold tape. Many routines use both.
How long does it take to see results on a keloid scar?
Most people need 8-12 weeks of consistent silicone therapy before noticing softening or flattening in an existing keloid scar. Scar tissue remodeling is gradual, and stopping early is the most common reason treatment appears to fail.
Why does my keloid keep growing even with treatment?
A keloid that keeps expanding despite consistent silicone therapy has likely outpaced what topical treatment alone can manage. That's the point to see a dermatologist for a corticosteroid injection, cryotherapy, or laser treatment.
Does surgery remove a keloid permanently?
Surgical excision on its own carries a high recurrence rate for keloids, which is why most dermatologists pair removal with silicone therapy or steroid injections afterward. Surgery without a follow-up plan often results in a keloid returning larger than before.
Do keloids need sunscreen?
Yes — UV exposure darkens keloid tissue and can undo weeks of fading progress from silicone therapy. Daily mineral sunscreen over the scar site is part of a complete keloid treatment routine, not an optional add-on.
What's the difference between a keloid and a hypertrophic scar?
A hypertrophic scar stays within the original wound border and often flattens on its own within a year or two. A keloid grows beyond the original injury site and typically needs ongoing silicone therapy, and sometimes clinical treatment, to manage.
One Last Thing
The detail most people skip: a keloid that's been silicone-treated and controlled still needs sun protection indefinitely, even after it flattens. Scar tissue stays more UV-reactive than the surrounding skin for years, which means the maintenance phase of treating an existing keloid scar in 2026 doesn't really end — it just gets shorter and less frequent.
