Calming a raised or keloid scar.
Some scars grow thick, raised, and firm — hypertrophic scars stay within the wound, while keloids spread beyond it. Topical silicone is a first-line, non-invasive way to help soften and flatten raised scars over time.

What raised and keloid scars are
Raised scars form when the body produces too much collagen during healing. A hypertrophic scar stays within the boundaries of the original wound; a keloid grows beyond it onto surrounding skin.
Both can be itchy, firm, or tender. They're more common on the chest, shoulders, and earlobes, and in some people more than others. Topical silicone is a recognized first step for managing them.
What causes raised and keloid scars
Several factors increase the chance of a raised or keloid scar:
Excess collagen. An overactive healing response lays down more collagen than needed.
Wound tension and location. High-tension areas like the chest and shoulders are more prone.
Individual tendency. Some people are simply more likely to form keloids, sometimes running in families.
Because raised scars can be stubborn, starting topical care early — once healed — and staying consistent gives the best chance of improvement.
What to look for
Features of raised and keloid scars
Raised and keloid scars tend to share certain features:
- Thick, raised, firm tissue
- A keloid that extends beyond the original wound
- Itching, tenderness, or a pulling sensation
- A shiny or darker surface
- A scar that grows over weeks or months
Managing a raised or keloid scar
Once the skin has healed, consistent topical care can help soften and flatten a raised scar:
Topical silicone first. Silicone gel is a recognized first-line, non-invasive option for raised and keloid scars.
Consistency is key. Raised scars need months of daily care; results build slowly.
Protect and don't pick. Shield from the sun and avoid irritating the scar.
Combine with medical care when needed. Stubborn keloids may need a doctor's treatments alongside topical care.
For large, growing, or painful keloids, work with a doctor — topical silicone often complements, rather than replaces, medical treatment.
When to seek care
See a doctor if
Keloids in particular often benefit from medical input. Seek advice if:
A scar keeps growing or spreading well beyond the wound
The scar is painful, very itchy, or interfering with movement
You're prone to keloids and want to prevent one after a procedure
The scar doesn't improve with consistent topical care
How Scarless helps
How Scarless helps raised and keloid scars
Scarless uses topical silicone, the recognized first-line approach for raised scars. The barrier hydrates and occludes the scar, which helps signal the skin to slow excess collagen — softening and flattening the scar over a consistent course.
- The occlusive silicone layer hydrates the scar and helps moderate excess collagen production.
- Squalane keeps the skin comfortable through the long course raised scars need.
- A stable vitamin C derivative supports more organized collagen and helps even tone.
- Drug-free and non-invasive — a sensible first step before or alongside medical treatments.
Common myths
“Keloids can't be improved.” They're stubborn, but consistent silicone care — sometimes with medical treatment — can soften and flatten them.
“Cutting a keloid out fixes it.” Surgery alone can trigger a larger keloid; that's why prevention and topical care matter.
“A raised scar will flatten on its own.” Some do, but many need active, consistent care to improve.
“Silicone only works on new scars.” Silicone can help older raised scars too, though they take longer.
Research highlights
Published research on scar care
Topical silicone is a recognized first-line, non-invasive option in published research on hypertrophic and keloid scars. Scarless's formula builds on that evidence.
Silicone
Advanced-formula silicone gel for preventing post-operative scars
An advanced-formula topical silicone gel applied twice daily for three months improved scar pigmentation, vascularity, pliability and height. The trial had no control group, and the authors describe the findings as preliminary, noting that larger controlled studies are warranted.
Silicone
Silicone scar gel for early intervention in scar management
A 100% silicone scar gel applied twice daily reduced Vancouver Scar Scale and Observer Scar Assessment Scale scores over twelve weeks, with no adverse events reported. There was no comparison group, so the study describes change over time rather than an effect measured against an alternative.
