Quick verdict
Keloid creams work best as part of a sustained, consistent routine over months rather than a quick fix. Silicone is the core active to look for, with onion extract and SPF as meaningful additions. For significant keloids, combine OTC treatment with professional management for the best outcomes.
ScarAway Silicone Scar Gel - Best for Evidence-Based Silicone Treatment
ScarAway Silicone Scar Gel uses self-drying medical-grade silicone that forms a thin, breathable layer over the scar surface. Silicone's mechanism of action involves regulating fibroblast activity and normalizing moisture levels in the scar tissue, which reduces excessive collagen deposition over time. Applied once or twice daily after the wound has fully closed, it progressively flattens raised keloid tissue and reduces redness over months of consistent use. ScarAway is widely stocked in pharmacies and sits at a reasonable price point for a silicone product with solid clinical backing. It works best on newer keloids but still shows results on older ones.

Keloid scars form when the skin’s healing response overproduces collagen, creating raised, firm growths that extend beyond the original wound. They can be itchy, tender, and cosmetically significant. While OTC creams alone won’t eliminate established keloids, consistent use of the right products can reduce their size, soften their texture, fade discoloration, and relieve associated itching. The five picks below are the most evidence-supported options available without a prescription. For significant keloids, combine topical treatment with dermatologist consultation.

ScarAway Silicone Scar Gel - Best for Evidence-Based Silicone Treatment
ScarAway Silicone Scar Gel uses self-drying medical-grade silicone that forms a thin, breathable layer over the scar surface. Silicone's mechanism of action involves regulating fibroblast activity and normalizing moisture levels in the scar tissue, which reduces excessive collagen deposition over time. Applied once or twice daily after the wound has fully closed, it progressively flattens raised keloid tissue and reduces redness over months of consistent use. ScarAway is widely stocked in pharmacies and sits at a reasonable price point for a silicone product with solid clinical backing. It works best on newer keloids but still shows results on older ones.
Mederma Advanced Scar Gel - Best for Onion Extract and Allantoin Combo
Mederma's formula combines onion extract, a studied ingredient for improving scar texture and reducing redness, with allantoin, which calms keloid-associated itching and promotes skin cell renewal. The combination addresses the cosmetic and comfort aspects of keloid scars simultaneously. It absorbs without leaving a heavy film and applies easily to the raised scar surface. Consistent once-daily use over three to six months is the recommended protocol, with most users reporting improvement in scar softness and color before significant flatness changes. It's the best OTC option for keloids that are primarily itchy or discolored rather than severely raised.
Kelo-Cote Silicone Scar Gel - Best Medical-Grade Silicone for Raised Scars
Kelo-Cote is positioned at a higher concentration of medical-grade silicone than many consumer scar products and is used in clinical settings following surgery. It dries to a transparent film within minutes, can be applied under makeup or sunscreen, and is durable enough for use on areas subject to movement. For established, moderately raised keloids, Kelo-Cote's silicone concentration provides a more intensive treatment than lower-tier silicone products. It's recommended by plastic surgeons and dermatologists as a first-line adjunct to professional keloid treatments. The higher price reflects its clinical-grade formulation and is well-supported by published evidence.
BioCorneum Advanced Scar Supervision - Best SPF-Included Silicone Treatment
BioCorneum distinguishes itself by incorporating SPF 30 into its medical-grade silicone base, addressing a critical but often overlooked aspect of scar management. UV exposure darkens scars and keloids significantly, particularly in people with deeper skin tones, reversing cosmetic progress from other treatments. Using BioCorneum provides both silicone flattening action and UV protection in one step, simplifying a protocol that otherwise requires separate products. It's particularly valuable for facial keloids and any scar on a sun-exposed body area. Apply once daily in the morning as part of a standard scar management routine.
Cimeosil Scar and Laser Gel - Best for Post-Procedure Keloid Management
Cimeosil is a crosslinked silicone gel frequently recommended for use after laser therapy, corticosteroid injections, or other in-office keloid treatments to maintain and extend professional results. The crosslinked formulation creates a more durable silicone barrier than standard silicone gels, with better adherence to raised scar surfaces during movement. It's appropriate for active keloid management in partnership with a dermatologist's treatment plan. Applied twice daily after professional treatments, it significantly extends the flattening effect between sessions. Solo use on established keloids also provides meaningful improvement in texture and discomfort over a three-to-six-month period.
What to look for
What to consider
Medical-grade silicone is the ingredient with the strongest OTC evidence base for keloid management. Look for products with a defined silicone concentration and a self-drying film format that allows for practical daily application. Onion extract adds complementary benefits for redness and texture. SPF protection matters significantly for any keloid in a sun-exposed area. Avoid products with strong fragrances on raised scars, as chemical irritants can trigger worsening. If a keloid is growing rapidly, causing pain, or not responding to three months of consistent OTC treatment, prioritize a dermatology referral.
Our verdict
Keloid creams work best as part of a sustained, consistent routine over months rather than a quick fix. Silicone is the core active to look for, with onion extract and SPF as meaningful additions. For significant keloids, combine OTC treatment with professional management for the best outcomes.
FAQs
OTC creams cannot fully remove keloid scars. Keloids are dense fibrous growths that extend beyond the original wound boundary and require medical interventions like corticosteroid injections, laser treatment, cryotherapy, or surgery for significant reduction. However, consistent use of silicone gel and onion extract products over several months can meaningfully flatten, soften, and fade keloid appearance.
Most keloid creams require consistent daily use for three to six months before visible improvement in flatness and color appears. Silicone-based products show early results in texture within six to eight weeks, with more significant changes appearing after three months. Results vary depending on keloid age, size, location, and skin type. Older keloids generally respond more slowly than newer ones.
Medical-grade silicone is the most evidence-supported OTC ingredient for keloid management. It works by creating a semi-occlusive barrier that hydrates the scar tissue, normalizes collagen production, and gradually flattens raised scar tissue. Onion extract has supporting evidence for reducing redness and improving texture. For best results, dermatologists recommend combining silicone application with OTC treatments and professional follow-up.
