The most effective scar minimization starts before your incision has fully closed and continues for 12 to 18 months afterward. No single product or technique eliminates a surgical scar entirely, but a layered approach of proper wound care, tension management, silicone therapy, sun protection, and good nutrition can make a significant difference in how flat, narrow, and color-matched your scar becomes.
Keep the Wound Clean and Moist
The old advice to “let it air out” works against you. Wounds that stay moist heal faster and produce less visible scars than wounds left to dry and scab over. A simple layer of petroleum jelly and a clean dressing is enough to maintain that moist environment in the first days and weeks after surgery.
When cleaning the incision, use saline or plain tap water. Avoid alcohol, hydrogen peroxide, and iodine-based solutions. These are cytotoxic to the very cells doing the repair work inside the wound. They belong to a past era of wound care and should not be used on an incision that is healing normally without signs of infection. Your surgeon will likely give you specific dressing instructions. Foam dressings, changed daily or every other day, are a common choice for controlling moisture levels at the wound surface.
Skip the Vitamin E
Vitamin E oil is one of the most popular home remedies for scars, and it’s one of the least effective. In a controlled study where patients applied vitamin E to one half of their surgical scar and a plain moisturizer to the other half, 90% of cases showed that vitamin E either had no effect or actually worsened the scar’s appearance. On top of that, 33% of patients developed contact dermatitis from the vitamin E. A basic emollient like petroleum jelly performs just as well for keeping the scar hydrated, without the risk of an allergic reaction.
Start Silicone Therapy Once the Wound Closes
Silicone is the most well-studied topical treatment for surgical scars. It comes in two main forms: adhesive silicone gel sheets that you place over the scar, and silicone-based creams or gels that you rub on. Both work by increasing hydration and raising the local skin temperature under an occlusive barrier, which helps regulate collagen production as the scar matures.
A meta-analysis of randomized controlled trials found that patients using silicone gel had significantly lower scar height and better pigmentation scores at six to eight months compared to untreated controls. The improvement in scar height was particularly pronounced. You can typically begin silicone therapy once sutures or staples are removed and the wound surface is fully closed, with no open or weeping areas. Most protocols call for consistent daily use over several months to see results.
Sheets work well on flat, accessible areas like the chest or abdomen. Gels are more practical for scars on joints, the face, or areas where a sheet won’t stay put.
Protect the Scar From the Sun
New scar tissue is highly vulnerable to UV radiation. Sun exposure triggers melanin production in the healing skin, which can permanently darken the scar and make it stand out against the surrounding tissue. This hyperpigmentation is especially common in people with medium to dark skin tones, but it affects everyone to some degree.
Use sunscreen with at least SPF 30 on the scar every time you’re in sunlight, and keep this up for 12 to 18 months after surgery. Physical barriers like clothing, medical tape, or silicone sheets also count as sun protection. This is one of the simplest steps in scar management and one of the most commonly skipped.
Manage Tension on the Incision
Mechanical tension is one of the biggest drivers of wide, raised, or abnormal scars. When skin around an incision is repeatedly stretched, the body responds by overproducing collagen, which leads to thicker, more visible scarring. This is why scars on the chest, shoulders, and joints (areas under constant stretching from movement) tend to heal worse than scars on the face or shin.
Keloids grow in the direction of the dominant skin-stretching force, which is why chest keloids often take on a butterfly or crab-claw shape reflecting the pull of arm movements. Hypertrophic scars behave similarly, widening and thickening in response to repeated mechanical stress.
What this means practically: follow your surgeon’s activity restrictions carefully. Avoid heavy lifting, vigorous exercise, or repetitive motions that strain the area around your incision during the healing window your surgeon specifies. Paper tape or adhesive strips placed across the scar can also help offload tension during daily movement. Some surgeons apply these at the time of suture removal and recommend continuing for weeks afterward.
Consider Scar Massage
Gently massaging a healed scar can help soften the tissue and improve its flexibility, particularly for scars that feel thick or tight. Among hand therapists surveyed about their clinical practice, the large majority begin scar massage immediately to one week after suture removal, while a smaller group waits up to three weeks post-surgery. Only about 5% delay massage until a problematic scar has already formed.
The optimal pressure, duration, and technique haven’t been firmly established in clinical research, but the general approach involves using your fingertips to apply moderate pressure in circular motions, perpendicular to the scar line, and along its length. Sessions of a few minutes, two to three times daily, are a common recommendation. Always wait until the incision is fully sealed. If the skin is still fragile, crusted, or open at any point, hold off.
Support Healing With Nutrition
Wound healing is energy-intensive. Your body’s caloric needs during recovery are estimated at 30 to 35 calories per kilogram of body weight daily, and protein requirements can increase substantially as your body rebuilds tissue. Protein deficiency directly impairs the production of collagen and the growth of new blood vessels at the wound site.
Several micronutrients play specific roles in how well your scar heals. Vitamin C is directly involved in collagen synthesis and antioxidant protection at the wound site. Zinc promotes the regeneration of new skin cells over the wound. Vitamin A supports the early inflammatory phase of healing. These don’t need to come from supplements if your diet is varied, but if you’ve been eating poorly before or after surgery, a deficiency in any of them can slow healing and worsen scarring. Good sources include citrus fruits and bell peppers for vitamin C, meat and legumes for zinc, and leafy greens or sweet potatoes for vitamin A.
Know Your Risk for Problem Scars
Not everyone scars the same way, and some people are more prone to raised or overgrown scars regardless of how well they care for the wound. Keloids, which grow beyond the boundaries of the original incision, have a strong genetic component. They occur most frequently in people of African descent, followed by Asian and Hispanic populations, and less commonly in Caucasians. If you have a family history of keloids or have developed them from previous injuries, mention this to your surgeon before the procedure so preventive measures can be built into your plan from the start.
Hypertrophic scars, which stay within the wound borders but become raised and red, don’t have the same genetic link but are more common on skin that is under tension. Incisions across joints, on the chest, or on the upper back carry a higher risk. In either case, the combination of silicone therapy, tension reduction, and sun protection is especially important for people with these risk factors.
