Scar tissue forms as your body’s natural repair response to any wound, and while you can’t eliminate a scar entirely, you can significantly improve its appearance, texture, and flexibility. The full process takes 6 to 18 months, and what you do during that window matters more than most people realize. A combination of consistent at-home care and, when needed, professional treatments can flatten raised scars, soften tight tissue, restore mobility, and fade discoloration.
How Scars Form and Why Timing Matters
Your body heals wounds in four stages: stopping the bleeding (minutes to hours), inflammation (first few days up to two weeks), rebuilding tissue (about day 4 through day 30), and remodeling. That last stage is where scar healing really happens. Starting about six weeks after the wound closes, your body continuously breaks down and reorganizes collagen fibers to strengthen the new tissue. This remodeling phase lasts 9 to 12 months, sometimes up to 18.
This is a crucial detail: during that remodeling window, the scar is still actively changing. Interventions you start early, while collagen is still being reorganized, tend to produce better results than waiting until the scar has fully matured. Once a scar reaches its final state at around 12 to 18 months, it becomes harder (though not impossible) to improve.
Scar Massage Techniques
Massage is one of the simplest and most effective things you can do at home. It breaks down adhesions, the spots where scar tissue binds to deeper structures and restricts movement. It also helps realign collagen fibers so the scar lies flatter and stays more flexible. You can start about two to three weeks after surgery or injury, once the wound has fully closed and there are no open areas or scabs.
Apply gentle but firm pressure with your fingertips using 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 underneath
- Cross-friction motions perpendicular to the scar to free up adhesions and restore mobility
For best results, massage for at least 10 minutes, twice a day, for six months. That sounds like a big commitment, but consistency is what drives results. You can use a plain moisturizer or silicone-based product to reduce friction during massage.
Silicone Sheets and Gels
Silicone gel sheeting is one of the best-studied at-home treatments for raised scars. The sheets create a sealed, hydrated environment over the scar that helps regulate collagen production and flatten the tissue over time. They’re available over the counter and are typically worn for 12 or more hours a day over several months. Silicone gels that dry into a thin film offer a similar effect for scars in areas where sheets won’t stay put, like the face or joints.
Protecting Scars From the Sun
New scars are extremely sensitive to UV light. Too much sun exposure can cause permanent darkening or reddening that won’t fade, and it can also make the scar thicker and harder. You should keep any new scar protected from the sun for at least 6 months to a full year, until it has fully matured.
The most reliable protection is covering the scar with clothing, tape, or an adhesive bandage. Sunscreen works too, but you need to reapply frequently, especially after sweating or water exposure. Don’t assume that once a scar looks healed on the surface, it’s safe in the sun. The tissue underneath is still remodeling and remains vulnerable.
Different Scar Types Need Different Approaches
Not all scars respond to the same treatment. The approach that works for a flat, discolored scar won’t necessarily help a raised or spreading one.
Hypertrophic scars are raised and firm but stay within the boundaries of the original wound. They often improve on their own over 12 to 18 months, and home treatments like silicone and massage can speed that process. Compression garments, steroid treatments, and silicone sheeting are all standard options.
Keloids are a different problem. They grow beyond the edges of the original wound, invading healthy skin, and they tend to cause pain and itching. Keloids have a strong tendency to recur even after removal, which makes them much harder to treat. Surgical removal alone often isn’t enough. The best outcomes combine excision with follow-up therapy to prevent regrowth. In one large series of nearly 500 keloids treated with surgery plus radiation, the overall recurrence rate was about 9%.
Atrophic scars, the depressed or pitted kind common after acne or chickenpox, involve a loss of tissue rather than an excess. These typically need professional treatments like laser resurfacing or microneedling to stimulate new collagen production beneath the surface.
Steroid Injections for Raised Scars
For hypertrophic scars and keloids that don’t respond to at-home care, corticosteroid injections are a first-line medical treatment. The injections reduce inflammation and break down excess collagen, gradually flattening the scar. You’ll typically need monthly injections for up to six months before seeing the scar flatten noticeably. The process can be uncomfortable, and some people experience temporary skin thinning or lightening at the injection site, but these effects usually resolve.
Laser Treatments
Several types of laser therapy can improve scars, but the evidence isn’t equal across all of them. A systematic review comparing different laser and energy-based treatments found that two stood out for reducing scar severity: low-level laser therapy and pulsed dye laser. Both produced statistically significant improvements in scar appearance compared to other interventions.
Pulsed dye laser works particularly well for red or pink scars because it targets blood vessels in the scar tissue, reducing redness and flattening the surface. Side effects are generally minor, with small bruises that resolve on their own. Fractional ablative CO2 laser, often marketed for acne scars and skin resurfacing, showed less consistent results in comparative data. That doesn’t mean it never works, but the evidence is stronger for pulsed dye laser and low-level laser therapy when treating surgical scars.
Laser treatments are typically done in a series of sessions spaced weeks apart. The number of sessions depends on the scar’s size, type, and location.
Topical Products and Natural Remedies
Onion extract (found in products like Mederma) is one of the most widely marketed natural scar treatments, but the clinical evidence behind it is limited. While it’s been used for decades, controlled studies evaluating its effectiveness are sparse, and the results that do exist are mixed. It’s unlikely to cause harm, but don’t rely on it as your primary approach for a significant scar.
Vitamin E is another common recommendation, but research has not consistently shown it improves scar appearance, and in some people it can cause contact irritation. Petroleum jelly or plain moisturizer, kept on consistently to maintain hydration, is often just as effective as expensive scar creams for keeping healing tissue soft and pliable.
What to Expect Realistically
Even with the best care, scars don’t disappear. The goal is a flat, soft, pale line that blends with surrounding skin and doesn’t restrict your movement. Most scars continue improving for the full 12 to 18 months of remodeling, so a scar that looks red and raised at three months may look dramatically different at one year without any intervention beyond basic care.
If you’re considering scar revision surgery, most surgeons prefer to wait 12 to 18 months to see the final result before operating. Early revision risks creating a new wound that heals just as poorly, especially if the factors that caused the original scarring (tension on the wound, genetics, location on the body) haven’t changed. The most productive thing you can do during that waiting period is commit to daily massage, silicone therapy, and sun protection.
