Boil scars can fade significantly with the right combination of at-home care and, for deeper scars, professional treatments. The approach that works best depends on whether your scar is raised above the skin, sunken into it, or simply discolored. Most boil scars respond well to consistent treatment over three to six months, though stubborn or large scars may take longer.
What Type of Scar You’re Dealing With
Boils can leave behind several different types of scars, and identifying yours helps you choose the right treatment. Raised, firm scars that stay within the boundaries of the original boil are hypertrophic scars. They’re usually pink to red, sometimes itchy, and tend to appear within weeks of the boil healing. These scars often soften and flatten on their own over time, though treatment speeds that process considerably.
Keloid scars are also raised and firm, but they grow beyond the edges of the original wound. They can appear purplish-red, feel smooth and rubbery, and sometimes develop months or even years after the boil has healed. Keloids are more persistent than hypertrophic scars and rarely resolve without treatment.
The third common type is an atrophic scar: a shallow pit or depression where the boil destroyed deeper layers of skin. These look similar to certain acne scars and form because the body didn’t produce enough collagen to fill the gap left by the infection. Discoloration without any texture change, either darker or lighter patches, is also common and usually the easiest type to treat.
Silicone Sheets and Gels
For raised scars, medical-grade silicone is one of the most effective at-home options. Silicone sheets are thin, reusable strips you place directly over the scar. They work by trapping moisture against the skin, which signals your body to slow down excess collagen production and soften the scar tissue. Research published in the Journal of Clinical and Aesthetic Dermatology found that wearing silicone sheets for at least four hours per day over a minimum of three months produced meaningful flattening. Extending use to six months helped prevent treated scars from thickening again.
Silicone gels offer the same active ingredient in a form that works better for scars on the face, neck, or joints where a sheet won’t stay put. You apply a thin layer once or twice daily and let it dry into a flexible film. Both formats are available over the counter at most pharmacies.
Over-the-Counter Scar Creams
Many OTC scar products contain onion extract and allantoin, a combination that has shown effectiveness across scars of various origins and severity levels. These ingredients work by reducing inflammation in the scar tissue and encouraging more organized collagen formation. Products like Mederma and similar gels use this formulation. You’ll typically need to apply them daily for at least four weeks to see initial improvement, with better results over two to three months of consistent use.
For dark spots left by boils, look for products containing vitamin C, niacinamide, or alpha hydroxy acids like glycolic acid. These ingredients help break up excess pigment and speed skin cell turnover. Sunscreen is essential during this process, since UV exposure darkens post-inflammatory pigmentation and can undo your progress.
Prescription Retinoids for Scar Remodeling
Tretinoin and similar prescription retinoids can improve both raised and depressed boil scars. These creams work by stimulating your skin’s collagen production and improving the way new collagen fibers organize themselves. In raised scars, retinoids help calm overactive tissue repair. In depressed scars, they encourage the skin to fill in lost volume. They also help fade dark marks left behind after inflammation.
Retinoids take time. Most people notice texture improvements after two to three months of nightly use, with continued progress over six months to a year. They make your skin more sensitive to the sun, so daily sunscreen is non-negotiable while using them. Your dermatologist can determine the right strength for your skin type and scar severity.
Steroid Injections for Raised Scars
When silicone and topical treatments aren’t enough for hypertrophic or keloid scars, corticosteroid injections are a well-established next step. A dermatologist injects a small amount of medication directly into the scar tissue, which breaks down excess collagen and flattens the scar. This approach flattens 50 to 100 percent of keloid scars, according to the American Academy of Family Physicians, though there is a 9 to 50 percent chance of recurrence.
Most people need two or three injections spaced about a month apart, but treatment can continue for six months or longer for stubborn scars. The injections are uncomfortable, but the provider can numb the area beforehand or use a brief freezing treatment to soften the scar first. Side effects can include thinning of the surrounding skin or lightening of skin color at the injection site, which is worth discussing with your provider, especially on darker skin tones.
Microneedling and Subcision
For depressed boil scars, microneedling is one of the most effective professional treatments. The procedure uses a device with fine needles that penetrate 0.5 to 3.5 millimeters into the skin, creating controlled micro-injuries that trigger your body’s natural healing response. As the skin repairs these tiny punctures, it produces new collagen that fills in the depressed scar from below. Most people see noticeable improvement after two to three sessions spaced four to six weeks apart.
Deep, tethered scars, the kind that seem anchored to the tissue underneath, often benefit from a technique called subcision before or alongside microneedling. A provider uses a small needle to break apart the fibrous bands pulling the scar downward, freeing the skin so it can rise to a more even level. A randomized controlled study found that combining microneedling with subcision produced statistically superior results compared to microneedling with other resurfacing technologies, though it required slightly more sessions (an average of about 2.5 compared to 1.5).
Laser Treatments
Laser resurfacing can address both texture irregularities and discoloration from boil scars. Fractional lasers create tiny columns of controlled damage in the scar tissue, prompting the body to replace it with healthier, more evenly organized skin. These treatments work well for both raised and depressed scars, and newer fractional technology limits downtime to a few days of redness and peeling rather than weeks of recovery.
For darker skin tones, non-ablative lasers (which heat the deeper layers without removing surface skin) carry less risk of causing new pigmentation problems. Your dermatologist can recommend the right laser type based on your scar characteristics and skin tone. Most people need three to five sessions for optimal results.
Preventing Scars From New Boils
If you’re prone to boils, how you manage them during the active infection makes a big difference in whether they leave lasting marks. At the first sign of a bump at a hair follicle, apply warm, wet compresses for 20 to 30 minutes, three or four times a day. This helps open the blocked pore and encourages the boil to drain on its own before the infection deepens.
Once a boil drains, cover it with a clean bandage and wash the area daily with antibacterial soap to prevent the infection from spreading. Resist the urge to squeeze or pop a boil yourself. Forcing it can push the infection deeper into the tissue, causing more damage and a worse scar. For larger or more painful boils, having a doctor drain the infection through a small, controlled incision speeds recovery and limits scar formation compared to letting it rupture on its own.
After the wound closes, start silicone gel or sheets early. Beginning scar prevention treatment while the skin is still in its active healing phase (the first few weeks to months) gives you the best chance of avoiding a noticeable scar altogether.
