Clinician comparing steroid injection, silicone gel sheeting and pressure therapy options for a raised scar

Steroid injection versus silicone and pressure: how clinicians choose.

Intralesional triamcinolone injection being administered into a keloid scar

Intralesional corticosteroid for keloids: what the evidence shows.

Intralesional triamcinolone is the first-line keloid treatment worldwide, yet response rates and recurrence vary widely. Here is what the dosing evidence and international consensus actually say.

Skin atrophy and pigment change at the site of a steroid injection into a scar

A Comprehensive Guide to Side Effects of Steroid Injections Into Scars

Steroid injections are the most common keloid treatment, and skin thinning, pigment loss and visible veins are their most common costs. Here is how often each happens and what reduces the risk.

Syringe prepared with a triamcinolone and 5-fluorouracil mixture for keloid injection

Efficacy of Corticosteroid Injection Combined with 5-FU for Keloids

Combining 5-fluorouracil with triamcinolone outperforms steroid alone for keloids in most trials, with fewer atrophy side effects. Here are the ratios, session counts and trade-offs.

Two healed scars of different appearance shown side by side on different skin tones

A Practical Guide to Why Two People Scar Differently: Formation Factors

Two people can get the same cut and end up with very different scars. Genetics, fibroblast behaviour, skin tone and the tension across the wound all play a part — and some of those factors you can influence.

Keloid scar treatment options from steroid injections to surgery with radiation

A Comprehensive Guide to Effective Keloid Scar Treatments

Keloids rarely go away on their own, and surgery without follow-up treatment often sees them return larger. Compare steroid injections, silicone sheeting, laser therapy, and surgery with radiation.

Diagram of body areas at highest risk for keloid scars, including the chest, shoulders, upper back and earlobes

All About Keloid Scar Body Location Risks

Where a keloid forms matters as much as why. Chest and shoulder keloids sit in high-tension skin and recur far more often than earlobe keloids, and that changes which treatment makes sense.

Detailed Guide to Pimple Raised Scar Treatment Options

Raised acne scars come in two forms that behave very differently. Hypertrophic scars may fade slowly on their own; keloids will not. Here is what actually flattens each type, and what to avoid.

Healed horizontal tummy tuck incision on the lower abdomen with raised keloid scar tissue

The Complete Guide to Keloid Tummy Tuck Scars

Keloids after abdominoplasty grow beyond the incision line and rarely fade on their own. This guide covers why they form, who is most at risk, and which surgical and non-surgical treatments have evidence behind them.

Everything You Need to Know About Keloid Scar Solutions

Keloids are stubborn and prone to recurrence. Here's how silicone, injections, lasers, surgery, and radiation compare, and how to choose the right one.

Keloid scar prevention cream and silicone gel applied to a healing post-surgery scar

Post-Surgery Keloid Prevention: Your Shopping List for Smooth Skin

Keloids are hard to remove once formed, so prevention is the priority. Here's the evidence on silicone gels, onion extract, timing, and who needs extra protection after surgery.

Raised keloid scar showing overgrown collagen tissue extending beyond the original wound

Why Your Body Overreacts to Tiny Scratches

Keloids form when wound healing won't switch off — collagen keeps building long after a cut has closed. Here's what drives that overreaction, who's most at risk, and the treatments with real evidence behind them.
