The most effective treatments for surgical scars are silicone-based products, consistent massage, and sun protection, all started once the wound has fully closed. A surgical scar takes 9 to 12 months to fully mature, and what you do during that window has a real impact on how flat, soft, and faded the final scar becomes.
How Surgical Scars Heal
Understanding the timeline helps you know when to start treatment and how long to keep it up. Your body heals a surgical wound in four overlapping stages. Bleeding stops within the first 24 hours. Inflammation kicks in over the next few days to two weeks, bringing redness and swelling. Then new tissue fills the wound over roughly the next month. The final stage, remodeling, is the longest: from about six weeks after surgery all the way to 9 to 12 months, your body continuously reorganizes the collagen fibers in the scar, making the tissue stronger and flatter over time.
This means your scar will look its worst in the early months. Redness, firmness, and slight raised texture are all normal during this period. Most topical treatments and massage should begin only after the wound is fully closed and any sutures or staples have been removed. Starting too early can reopen the wound or cause irritation.
Silicone Products
Silicone is the best-studied topical treatment for surgical scars. It comes in two main forms: adhesive gel sheets that you place over the scar, and a liquid gel that dries into a thin film after application. A comparative study in the Journal of Korean Medical Science found no significant difference in efficacy between sheets and gel, though the gel was rated more convenient by patients.
Silicone works by trapping moisture against the scar surface, which signals your body to slow down excess collagen production. This helps keep the scar flat and soft. Sheets need to be worn for at least 12 hours a day, and many people wear them overnight. Topical gels need to be reapplied multiple times per day and should be paired with sunscreen, since they don’t block UV light the way a sheet does. For either format, plan on consistent daily use for at least two to three months to see meaningful improvement.
Scar Massage
Once your incision is fully healed, regular massage is one of the simplest and most effective things you can do. For best results, massage the scar for at least 10 minutes, twice a day, for six months. That sounds like a big commitment, but it makes a noticeable difference in how soft and mobile the tissue feels.
Use gentle pressure with your fingertips and rotate through three types of motion:
- Linear motions along the length of the scar to reduce skin tension
- Circular motions over the scar to break down fibrous tissue and improve the alignment of the tissue underneath
- Cross-friction motions perpendicular to the scar to break down adhesions (places where the scar sticks to deeper tissue) and restore mobility
You can use a plain moisturizer, vitamin E oil, or your silicone gel as a lubricant during massage. The mechanical action matters more than whatever product you rub in.
Sun Protection
New scars are extremely vulnerable to UV damage. Sun exposure during the first year can cause permanent darkening (hyperpigmentation) that no cream will fully reverse. Keep any new scar out of the sun for six to 12 months. Use a broad-spectrum sunscreen and reapply frequently, especially after swimming or sweating. Clothing or medical tape that covers the scar is even more reliable than sunscreen alone.
Nutrition That Supports Healing
What you eat in the weeks after surgery directly affects how your wound heals and how the scar forms. Three nutrients are especially important. Vitamin A helps your body produce new skin cells. Zinc supports skin healing and growth. Magnesium helps repair broken tissue and reduce swelling. You can get these from a balanced diet (sweet potatoes, eggs, and leafy greens for vitamin A; meat, seeds, and legumes for zinc; nuts and whole grains for magnesium), or through a supplement if your intake is low. Protein is also essential, since collagen is built from amino acids.
Over-the-Counter Scar Products
Beyond silicone, you’ll find products containing onion extract (sometimes listed as Allium cepa or the brand ingredient Cepalin). A controlled study on cesarean section scars found that patches containing onion extract and allantoin improved scar pigmentation, relief, and pliability compared to untreated controls. These products are widely available in gels and patches and can be a reasonable option if you prefer something other than silicone, though silicone still has a larger body of evidence behind it.
Vitamin E is a popular home remedy, but the clinical evidence for applying it directly to scars is weak. Some studies have found no benefit over plain moisturizer, and a small percentage of people develop contact irritation from topical vitamin E. It won’t hurt most scars, but don’t count on it as your primary treatment.
Laser Treatments for Stubborn Scars
If your scar remains red, raised, or textured after it has fully matured, laser therapy can make a significant difference. The two most common types target different problems.
Pulsed dye lasers target the blood vessels that give a scar its pink or red appearance. They’re a strong option for scars that remain visibly flushed well after healing. Fractional resurfacing lasers create tiny controlled injuries in the scar tissue, prompting your body to remodel the collagen and smooth out texture. A series of fractional resurfacing treatments can achieve 50 to 75 percent scar improvement, with relatively minor downtime: typically one to two days of swelling, a few days of redness, and about a week of peeling. For deeper scars, ablative fractional lasers may deliver similar results in fewer sessions, though recovery takes longer.
Lasers are typically reserved for scars that haven’t responded well to topical treatments and massage, and they’re usually started after the scar has matured (around the one-year mark), though some dermatologists begin earlier for very red or raised scars.
When a Scar Becomes a Bigger Problem
Most surgical scars flatten and fade on their own with basic care. But two types of abnormal scarring are worth watching for. Hypertrophic scars are raised and firm but stay within the boundaries of the original incision. They often improve over time, especially with silicone and massage. Keloids are different: they grow beyond the edges of the wound, invading healthy skin, and they tend to be painful, itchy, and disfiguring. Keloids also have a strong tendency to come back after removal.
Keloid risk is significantly higher in people with darker skin tones. African Americans and Asian Americans are roughly 2.5 to 3 times more likely to develop keloids than non-Hispanic white Americans. If you have a personal or family history of keloids, let your surgeon know before any procedure, since early preventive treatment (like silicone or pressure therapy starting right after wound closure) can reduce your risk.
Putting It All Together
The most effective scar care routine combines several of these approaches rather than relying on just one. Once your wound is fully closed, start with silicone gel or sheets and twice-daily massage. Protect the scar from the sun for at least the first year. Eat enough protein, zinc, and vitamins A and C to give your body the raw materials it needs. If the scar is still bothersome after 9 to 12 months of maturation, that’s when laser treatments or other in-office procedures become relevant. Consistency over months matters far more than which specific product you choose.
