Mederma Advanced Scar Gel - Best for General Old Scar Improvement
Mederma is one of the most widely recognized scar treatment brands, and the Advanced Scar Gel is its most effective formula. It contains Cepalin (onion extract), allantoin, and hyaluronic acid - a combination that softens scar tissue, improves texture, and provides hydration that supports the remodeling process. For old scars, Mederma recommends twice-daily use for six months or more. The gel absorbs cleanly without leaving a visible residue and can be used on the face and body. It's dermatologist-tested and available at most pharmacies. Users report gradual but consistent improvement in both texture and discoloration with sustained use.

Old scars require patience and the right active ingredients. Unlike fresh scars, mature scar tissue has fully remodeled, which means treatment has to work through denser, more established layers of skin. The five creams below are formulated with ingredients that have shown real benefit for older scars – silicone, retinoids, vitamin C, and onion extract among them. Consult a dermatologist for severe scarring or before using prescription-strength products.

Mederma Advanced Scar Gel - Best for General Old Scar Improvement
Mederma is one of the most widely recognized scar treatment brands, and the Advanced Scar Gel is its most effective formula. It contains Cepalin (onion extract), allantoin, and hyaluronic acid - a combination that softens scar tissue, improves texture, and provides hydration that supports the remodeling process. For old scars, Mederma recommends twice-daily use for six months or more. The gel absorbs cleanly without leaving a visible residue and can be used on the face and body. It's dermatologist-tested and available at most pharmacies. Users report gradual but consistent improvement in both texture and discoloration with sustained use.
ScarAway 100% Silicone Scar Gel - Best for Raised Scars
ScarAway uses 100% medical-grade silicone in gel form to flatten raised and hypertrophic scars. Silicone works by creating an occlusive layer over the scar that normalizes moisture levels and reduces excess collagen production in the scar tissue. The gel format is more convenient than silicone sheets for older scars in hard-to-cover areas. It dries to form a thin transparent film and can be worn under clothing or on exposed areas. Consistent once or twice-daily use over several months is the recommended protocol. It's one of the most evidence-backed options available over the counter for raised scar reduction.
Bio-Oil Skincare Oil - Best for Scar Discoloration and Uneven Texture
Bio-Oil has been used for scar care for decades and remains popular because it visibly improves skin tone and texture over time. It contains vitamins A and E, calendula oil, lavender oil, and chamomile alongside its proprietary PurCellin Oil technology. For old scars with significant discoloration or uneven surface texture, Bio-Oil's combination of skin-conditioning oils and antioxidants provides noticeable improvement. It's not suitable for raised scars as its oil base doesn't have the same flattening effect as silicone. Massage it gently into the scar twice daily for best results, as the physical massage motion itself also aids scar softening.
Differin Adapalene Gel 0.1% - Best Retinoid Option for Resurfacing
Differin's adapalene gel is the only over-the-counter retinoid in the United States and is effective for improving the surface appearance of old, flat scars by accelerating cell turnover. It gradually resurfaces the top layers of the skin, which can smooth uneven texture and lighten hyperpigmented scar marks over consistent use. It's most effective on flat scars rather than raised ones. Start with every other night application to allow the skin to adjust, as retinoids can cause initial dryness and peeling. It pairs well with a hydrating, non-comedogenic moisturizer applied after it has absorbed.
Cica-Care Silicone Gel Sheet - Best Clinical-Grade Silicone Sheet
Cica-Care is a clinical-grade silicone gel sheet originally developed for medical settings and widely used by plastic surgeons and dermatologists for post-surgical scar management. The sheets can be cut to fit any scar shape and are reusable for up to 28 days with proper care. They provide the most consistent silicone contact of any over-the-counter scar treatment, making them particularly effective for old, raised, or discolored surgical scars. The higher price point reflects the medical-grade silicone quality. For scars that haven't responded well to gel formats, sheets offer superior coverage and sustained occlusion throughout the wearing period.
Buying considerations
What to consider
Identify your scar type before choosing a product. Raised scars need silicone-based products. Flat, discolored scars respond to vitamin C, niacinamide, or retinoids. General texture improvement benefits from consistent oil massage combined with active ingredients. Look for products with clinical backing or dermatologist development, especially for older scars. Commit to at least three months of daily use before evaluating whether a product is working.
Final word
Treating old scars requires consistency above all else. None of these products deliver overnight results, but with sustained daily use, all five have helped real users improve the appearance of mature scar tissue. Choose based on scar type and give the product a full treatment cycle before drawing conclusions.
Questions answered
Yes, creams can improve the appearance of old scars, though complete removal is rarely possible without clinical procedures. Silicone-based products work by hydrating and flattening raised scar tissue over time. Retinoid creams stimulate cell turnover to gradually resurface the top layers of skin. Results depend on scar type, age, and consistency of use - realistic improvement takes three to six months of daily application.
Old scars typically require longer treatment periods than fresh ones. Expect a minimum of eight to twelve weeks before visible changes appear, with the most noticeable improvement often occurring between three and six months. Silicone gels and sheets require daily use for the full duration. Stopping early is the most common reason users don't see results. Consistent daily application is more important than product choice in most cases.
Flat hyperpigmented scars (dark marks left after wounds heal) respond best to brightening creams containing vitamin C, niacinamide, or kojic acid. Raised hypertrophic scars respond well to silicone gels. Atrophic or pitted scars respond better to retinoids. Keloid scars are generally less responsive to over-the-counter creams and may require professional treatment. Knowing your scar type helps you choose the most effective product.
