Silicone-based products are the gold standard for treating scars after surgery, backed by more clinical evidence than any other option. But the best results come from combining several approaches at the right times during healing, not relying on a single product. Your options range from simple at-home care starting within days of surgery to in-office procedures months later, and the choices you make in the first few weeks matter most.
Start With Wound Care in the First Two Weeks
Before you think about scar-specific treatments, the priority is keeping your incision moist and protected. Applying petroleum jelly or antibiotic ointment can begin on the day of surgery and should continue twice daily for one to three weeks. This isn’t just about preventing infection. Moist wounds heal faster and form less noticeable scars than wounds left to dry out and scab over. During this phase, protect the incision from sun exposure, which can darken a healing scar permanently.
Silicone Products: The First-Line Treatment
Once the wound has fully closed, silicone is the single most effective topical treatment for preventing raised, thickened scars. It works by trapping moisture in the scar tissue, which signals your body to slow down collagen production and keep the scar flat. Clinical trials consistently show that both silicone gel sheets and topical silicone gels outperform placebo in reducing scar thickness, redness, and irregularity.
Silicone sheets are adhesive strips you place directly over the scar. For best results, they should be worn at least 23 hours a day, removed only for bathing. Topical silicone gels are applied twice daily and dry into a thin, invisible layer, making them more practical for scars on visible areas like the face or hands, or on joints where a sheet won’t stay in place. Studies comparing the two formats head-to-head found no significant difference in effectiveness, so the choice comes down to convenience and location of your scar.
Plan to use silicone products for at least six months. Scar remodeling is a slow process, and shorter treatment periods produce less improvement. You can find both formats over the counter at most pharmacies.
Scar Massage: Simple and Effective
About two to three weeks after surgery, your scar has built enough strength to handle gentle massage. This is one of the most effective and cost-free things you can do. Massage breaks up adhesions (places where scar tissue sticks to deeper layers), softens the tissue, and improves flexibility around the scar.
The typical recommendation from therapists is three to five times daily, five minutes per session, for at least 12 weeks. Use firm, circular pressure with a fingertip, moving along and across the scar. You can apply a plain moisturizer or your silicone gel during massage to reduce friction. It shouldn’t be painful, but you should feel the tissue moving beneath your finger.
What About Vitamin E and Onion Extract?
Vitamin E is one of the most popular home remedies for scars, but clinical evidence tells a different story. In a study of surgical scars, topical vitamin E showed no benefit in improving scar appearance in 90% of cases and actually worsened the cosmetic outcome in some patients. On top of that, 33% of patients developed contact dermatitis, an itchy, red skin reaction. Despite its reputation, vitamin E applied to surgical wounds should be avoided.
Onion extract gels (sold under brand names like Mederma) have more nuanced evidence. Some trials show improvements in redness and pliability compared to placebo, and onion extract has earned a place in some clinical guidelines as a reasonable option. However, a meta-analysis of randomized controlled trials concluded that onion extract gel is not clearly better than other topical treatments for scar management. It’s not harmful, but it’s not a substitute for silicone.
Laser Therapy for Stubborn Scars
If your scar remains red, raised, or textured after several months of at-home care, laser treatment is one of the most effective next steps. Over the past decade, laser therapy has moved from an experimental option to a frontline treatment for problem scars.
The two main types work differently. Pulsed dye lasers target the blood vessels that make a scar look pink or inflamed, and they’re particularly effective for red, raised scars. Fractional lasers create microscopic channels in the scar tissue, triggering your body to replace disorganized collagen with smoother, more normal-looking skin. Fractional resurfacing can produce 50 to 75% improvement in scar appearance over a series of treatments.
More aggressive ablative fractional lasers may achieve similar results in fewer sessions but require two to four weeks of healing time per treatment. Less intensive fractional lasers and microneedling devices involve shorter recovery, with redness and swelling resolving within about five days. For people with darker skin tones, microneedling or radiofrequency microneedling tends to carry less risk of pigmentation changes than CO2 laser treatment.
Steroid Injections for Raised Scars
Scars that become noticeably raised, firm, or ropy despite topical treatment may benefit from steroid injections directly into the scar tissue. These injections shrink the excess collagen that makes a scar thick and prominent. Treatments are spaced every three to six weeks and repeated until the scar flattens, which can take several months.
Steroid injections alone reduce scar size by roughly 73%. When combined with another injectable medication, that number climbs to about 92%. Your doctor will determine the right approach based on how your scar is responding. These injections can sting, but they’re quick, and results are often visible within a few weeks of the first treatment.
Timing Makes the Difference
Scar treatment isn’t a single decision but a timeline. Here’s a practical sequence:
- Day of surgery through week 2 to 3: Keep the wound moist with petroleum jelly or antibiotic ointment. Protect from sun.
- Weeks 2 to 3: Begin scar massage (three to five times daily, five minutes each) and start silicone gel or sheets.
- Months 1 through 6: Continue silicone and massage consistently. Most surgical scars improve dramatically during this window.
- After 6 months: If the scar is still raised, red, or textured, consider laser treatments, steroid injections, or microneedling.
Scars continue remodeling for up to 18 months after surgery. Starting treatment early and staying consistent gives you the best chance of a flat, pale scar that blends into the surrounding skin. The combination of silicone, massage, and sun protection costs very little and handles the majority of surgical scars without ever needing a procedure.
