Frequently Asked Questions
Clear answers to common questions about keloids, scar healing, and treatment. Explore the details in our guides.
How is a keloid different from a hypertrophic scar?
A keloid grows beyond the edges of the original injury, while a hypertrophic scar stays within them. Both can be raised, firm, itchy, or painful. Hypertrophic scars may gradually soften and flatten; keloids usually persist. Because symptoms overlap, a clinician should confirm the scar type before you choose a treatment.
Why is my scar getting bigger, even months later?
Healing continues beneath the skin after a wound closes. A scar may widen under tension, become thicker within the wound, or develop into a keloid that extends beyond it. Aging alone does not mean a scar is growing: older acne scars can simply look more noticeable as surrounding skin loses firmness. Ongoing enlargement, new thickening, or restricted movement deserves assessment.
Will my scar fade, and how long can redness last?
Many scars gradually become softer and less noticeable over months or years; changes can continue for two years or longer. This is a broad guide, not a deadline. A closed scar can stay pink or red while it matures, without necessarily being a keloid. True keloids usually do not flatten on their own. Increasing thickness, pain, or spreading redness should be checked rather than simply watched.
Why does a keloid itch or hurt, and when should I seek help?
Inflammatory activity and altered nerve sensitivity may contribute to itching, tenderness, or pain. Itching can occur during growth, but it does not prove that the scar is getting bigger. Arrange a review if symptoms disturb sleep, daily activities, or movement. Seek prompt medical advice for suddenly worsening pain, warmth, spreading redness, swelling, or discharge, which may indicate infection or another complication.
Can a keloid turn into cancer?
A typical keloid is benign and is not normally expected to become cancerous. Rare reports of cancer in scarred tissue do not establish that ordinary keloids commonly transform into cancer, and some other skin growths can resemble keloids. A persistent open sore, repeated unexplained bleeding, or an unusual change needs prompt assessment. A dermatologist may recommend a biopsy when the diagnosis is uncertain.
Which keloid treatment is best for me?
There is no single best treatment for every keloid. The plan depends on the diagnosis, size, location, skin tone, symptoms, previous treatment, and your goals. Options include injections, silicone-based care, cryotherapy, lasers, and selected surgery with additional treatment. The aim may be less itching, a flatter scar, or easier movement rather than complete disappearance. Several appointments and follow-up may be needed, including for newly formed scars.
Can silicone gel or sheets remove an old keloid?
Silicone helps retain moisture over healed skin and may be included in scar care, but it cannot reliably erase an established keloid. Research on silicone sheets for existing keloids is of very low certainty. Start only once the skin has fully healed, never over an open wound or scab. Follow the product instructions and your clinician’s advice about duration, irritation, and when to review progress.
How do steroid injections work, and how many will I need?
Corticosteroid medicine is injected directly into the scar to reduce inflammation and excessive scar activity. It may soften or flatten the tissue and ease itching or pain. Multiple sessions are often needed, usually several weeks apart, with the schedule adjusted to your response. Possible side effects include injection pain, skin thinning, visible small blood vessels, and pigment changes. Improvement does not rule out later regrowth.
Does cryotherapy permanently remove a keloid?
Cryotherapy uses controlled freezing to reduce scar tissue, often in selected smaller keloids. Surface freezing and freezing from inside the scar are different procedures, with different recovery needs. Repeat sessions may be needed, and recurrence remains possible. Risks include pain, blistering, delayed healing, and pigment changes that can be permanent, especially lighter patches in darker skin. Home freezing products are not a substitute for clinical treatment.
Can laser treatment remove every type of scar?
No. Lasers have different purposes: pulsed-dye laser may target redness, while fractional CO₂ treatment may address selected texture or thickness concerns. Evidence for treating keloids remains limited, and complete removal is not guaranteed. Results for pitted acne scars cannot simply be applied to raised keloids. Skin tone, previous abnormal scarring, recovery time, and risks such as pigment changes, infection, or additional scarring should guide the choice.
Why can a keloid return after surgical removal?
Surgery removes existing tissue but creates a new wound in skin already prone to excessive scarring. The keloid can return, sometimes larger than before, so surgery alone should not be presented as a permanent cure. Depending on the scar, follow-up treatment may include injections, fitted pressure devices, or specialist-selected radiotherapy. Discuss the timing, risks, and recurrence plan before surgery; additional treatment also cannot guarantee that regrowth will never occur.
Will a raised burn scar go away, especially on the chest?
Some hypertrophic burn scars soften and flatten over time, while true keloids grow beyond the original burn and usually persist. Chest scars can be particularly challenging because of repeated stretching and skin tension. Treatment should match the scar type and may aim to improve comfort, thickness, or movement. Evidence for pressure garments or lasers in hypertrophic burn scars does not automatically establish the same benefit for a chest keloid.
Is a bump after ear piercing always a keloid?
No. Irritation, infection, an allergic reaction to jewelry, or another type of scar can also cause a bump. A keloid typically persists and grows beyond the original injury, but an examination may be needed. Confirmed ear keloids may be treated with injections or selected surgery plus aftercare. Professionally fitted pressure earrings can form part of postoperative treatment; tightening ordinary earrings is not an equivalent approach.
Can creams, massage, or home remedies flatten a keloid?
There is insufficient reliable evidence that household remedies, vitamin E, onion-extract creams, or massage permanently remove an established keloid. A plain moisturizer may help dry, healed skin feel more comfortable, but comfort is different from flattening scar tissue. Avoid aggressive rubbing and products that burn or irritate. Sun protection supports healed skin care; it does not remove a keloid. Keep any treatment plan appropriate to whether the skin has fully healed.
Can tattoos or hair transplants cause keloids?
Both involve skin injury and can trigger excessive scarring in susceptible people. A raised tattoo may also be an ink reaction, so it needs assessment before scar treatment. Neither FUE nor FUT hair transplantation is scar-free, although their usual scar patterns differ. Tell your clinician about previous keloids and healing problems before another procedure. Tattoo cover-ups, re-piercing, or further surgery create new injuries and cannot be assumed to be risk-free.
