Quick verdict
Mederma Advanced Scar Gel is the best all-purpose starting point for most scar types, while ScarAway Silicone is the right choice for any raised or post-surgical scar. The key to scar cream success is starting early and committing to daily application for a minimum of 8 to 12 weeks. Pair with SPF every morning for the fastest, most complete improvement in scar appearance.
Mederma Advanced Scar Gel
Mederma is the most clinically studied OTC scar cream and the most frequently recommended by dermatologists and surgeons alike. The active ingredient Cepalin - a standardized onion extract - modulates fibroblast activity to normalize disordered collagen in scar tissue, gradually restoring a more normal skin structure. Allantoin and hyaluronic acid support cell renewal and maintain hydration in the scar. Apply once daily to new scars (under 6 months old) or three times daily to older scars. Results are visible in 4 to 8 weeks on fresh scars; older scars require 3 to 6 months of consistent treatment. Works on surgical, injury, acne, and burn scars.
Scars from surgery, injury, or acne respond differently to treatment. These five top-rated scar creams cover all scar types - raised, flat, dark, or pitted - with clinically proven results.
Scars come in many forms – raised keloids, flat hyperpigmented marks, pitted acne scars, and thick surgical lines – and each responds best to targeted ingredients. The common thread across all effective scar creams is the ability to influence the skin’s remodeling process, either by modifying collagen structure, improving pigmentation, or repairing texture. These five creams address the full spectrum of scar types with the strongest evidence behind them in 2026.

Mederma Advanced Scar Gel
Mederma is the most clinically studied OTC scar cream and the most frequently recommended by dermatologists and surgeons alike. The active ingredient Cepalin - a standardized onion extract - modulates fibroblast activity to normalize disordered collagen in scar tissue, gradually restoring a more normal skin structure. Allantoin and hyaluronic acid support cell renewal and maintain hydration in the scar. Apply once daily to new scars (under 6 months old) or three times daily to older scars. Results are visible in 4 to 8 weeks on fresh scars; older scars require 3 to 6 months of consistent treatment. Works on surgical, injury, acne, and burn scars.
ScarAway Silicone Scar Gel
For raised or thickened scars - including hypertrophic scars and early keloids - silicone gel is the most evidence-backed topical treatment available. ScarAway delivers 100% medical-grade silicone in a convenient gel format that dries quickly to an invisible film. Silicone's mechanism is well established: it normalizes hydration in the scar microenvironment, signaling fibroblasts to reduce excess collagen production and flatten the raised tissue. Apply twice daily to clean, dry scar tissue. Clinical studies show consistent improvement in scar height, firmness, and color after 8 to 12 weeks of use. The best choice after any surgery or significant skin injury.
Bio-Oil Skincare Oil
Bio-Oil's unique PurCellin Oil formula - a lightweight carrier system that reduces the thickness of the oil blend for better skin penetration - combined with vitamins A and E and botanical extracts, makes it exceptionally effective for improving scar color and skin texture. It works on both the redness of new scars and the brown discoloration of older post-inflammatory marks. The massaging action required during application also improves blood circulation and breaks up scar adhesions over time. Apply twice daily using firm circular strokes for at least 3 months. Best used on flat or minimally raised scars where discoloration is the primary concern.
Differin Adapalene Gel
Differin Adapalene Gel 0.1% is the best OTC option for acne scars and post-inflammatory hyperpigmentation. Adapalene is a third-generation retinoid that promotes cell turnover, accelerates the fading of dark marks, and - with consistent long-term use - improves the texture of pitted acne scarring by stimulating dermal remodeling. Originally prescription-only, it is now available OTC and represents the most potent retinoid accessible without a doctor's visit. Apply at night, starting 2 to 3 times per week and building to nightly use. Always use SPF 30+ in the morning. Not suitable for pregnant or nursing users.
Palmer's Cocoa Butter Scar Serum
Palmer's delivers an affordable scar-fighting serum that punches above its price with a synergistic combination of cocoa butter for deep moisture, vitamin C for brightening discolored tissue, and centella asiatica (cica) for promoting healthy new collagen formation. It is the best daily maintenance product for keeping healed scar tissue soft, hydrated, and gradually improving in appearance over weeks and months. The serum absorbs well and can be used on the face, body, and all scar types without irritation. An excellent option for anyone wanting a simple, affordable, single-product scar routine.
What matters most
Silicone for raised scars
- the most evidence-backed topical ingredient for flattening hypertrophic or keloid tissue; use before trying anything else - **Retinoid or vitamin C for dark/discolored scars** - these ingredients address pigmentation changes rather than structural collagen issues - **Early treatment** - starting scar cream application as soon as wounds close produces dramatically better results than waiting months - **SPF as a daily companion** - UV exposure darkens scars and prevents the skin from naturally fading them; sunscreen is essential alongside any scar treatment

Frequently asked
Silicone-based gels and sheets are the first-line treatment recommended by plastic surgeons for surgical scars. Silicone regulates moisture, reduces excessive collagen production, and flattens raised tissue over 2 to 3 months of consistent use. Start once the incision is fully closed - typically 3 to 4 weeks post-surgery. Mederma and ScarAway are the most widely recommended OTC options for post-surgical scar management.
Yes, though results are more gradual than on new scars. Old scars have completed their remodeling phase, so improvement requires sustained use - 3 to 6 months of twice-daily application. Silicone can still soften and flatten raised old scars; retinol and vitamin C can improve the color and texture of discolored or depressed old scars. Patience and consistent application are essential. For very old or thick keloid scars, in-office treatments may produce better results.
A hypertrophic scar stays within the original wound boundary and may flatten over time without treatment. A keloid extends beyond the wound boundary and continues to grow. Both respond to silicone treatment - silicone gel or sheeting is the first-line topical treatment for both types. Keloids often require additional in-office treatments like corticosteroid injections or laser therapy. Silicone-based products are the correct starting point for either type.
