Most scars respond to the right intervention. The hard part is matching the treatment to the scar type – raised vs. sunken, fresh vs. old, superficial vs. deep. Clinical options range from office procedures to actual surgery, and picking the wrong one wastes time and money. Here’s what’s available and what each one actually does.
Microneedling
Tiny punctures in the skin trigger collagen production and tissue remodeling. That sounds harsh but it’s one of the gentler options on this list. Professional microneedling uses longer needles than anything sold for home use, which means it can reach deep enough to produce real results on atrophic (sunken) scars and some raised tissue.
At-home dermarollers are cheaper but the penetration is limited – treat them as maintenance between sessions, not the main event. You need 4-6 professional sessions spaced about a month apart. Results build slowly as collagen remodels over several months.
Chemical Peel
Peels remove outer skin layers to drive cell turnover and collagen production. The acid type and concentration determines how deep it goes. Alpha hydroxy acids (glycolic, lactic) exfoliate the surface and fade pigmentation. Salicylic acid is oil-soluble, so it penetrates into pores and handles acne-related texture better.
For surface discoloration: start with a 2% salicylic acid toner or serum three nights a week. Increase to daily if your skin tolerates it after two weeks. For deeper work at home, 30% glycolic acid once a week – apply for 3-5 minutes max, then rinse. TCA and phenol peels reach scar tissue directly but require a dermatologist. Push too hard on at-home options and you’ll damage your moisture barrier and make everything worse.
Laser Therapy
Fractional and non-ablative lasers target the skin’s deeper layers. Controlled thermal injury triggers the repair process – new collagen builds, existing tissue remodels. The result is improved texture, reduced indentation depth, and softened raised areas depending on what you’re targeting.
Plan for 3-5 sessions. Ablative lasers produce more dramatic results but need about a week of healing. Non-ablative options are gentler with minimal downtime but require more sessions. For keloids specifically, laser alone rarely works – it needs to pair with steroid injections. Cost runs $500-$2,500 per session. Most people do a single maintenance session annually after the initial series.
Corticosteroid Injections
These are for raised scars only – keloids and hypertrophic tissue. The steroid reduces inflammation and physically flattens the raised area. A dermatologist injects directly into the scar every 4-6 weeks. Most people see visible change within a few sessions. Side effects can include minor skin thinning or temporary discoloration at the injection site – for keloids that have been building for months, that trade-off is easy to make.
Dermal Fillers
Fillers address volume loss and indented areas. They’re not appropriate for raised scars – the method adds volume beneath the surface to push it back level, which does nothing for tissue that’s already elevated. Hyaluronic acid fillers (Restylane, Juvederm) are standard. Results are immediate and last 9-12 months. Cost is $600-$1,500 per session depending on the volume required.
Find a practitioner who specializes in the specific area you’re treating. Some injection sites are technically demanding and you don’t want someone learning on your face.
Subcision
A needle is inserted under the scar and swept to sever fibrous bands pulling the skin down into deeper tissue. Only works for atrophic (depressed) scars – the whole mechanism is about releasing a tether, which is irrelevant for raised tissue. Typically combined with fillers or laser for better outcomes. There’s bruising afterward. For deep pitted damage, the improvement can be dramatic where nothing surface-based would reach.
Punch Excision
For very small, very deep scars – classic ice-pick acne scarring – a dermatologist punches out the scar and either sutures the hole or fills it with a small skin graft. The replacement scar is smaller and shallower. Recovery is minimal (a few days of keeping it clean). This is one of the few options that genuinely works on ice-pick depth when laser and topicals can’t reach.
Scar Revision Surgery
When a scar is large, disfiguring, or restricts movement, surgical revision removes the old scar and re-closes the wound with meticulous technique. There will still be a scar – you can’t cut skin without making one. But it’ll be placed along natural skin tension lines and healed under optimal conditions. This is real surgery with real recovery time and risks. Not the first step for most people.
Pressure Therapy
Compression garments worn continuously over burn scars (or large scars prone to excess collagen buildup) physically prevent the tissue from piling up. 12-23 hours a day for 6-12 months. Uncomfortable and conspicuous. For large burn scars or patients prone to keloid formation, it’s one of the most effective non-surgical options available. For smaller scars, there are easier paths.
Cryotherapy
Liquid nitrogen freezes and destroys raised scar tissue. Most effective on keloids and hypertrophic scars where the goal is reducing bulk and softening texture. Multiple sessions required. Risk of hypopigmentation – the treated area may lighten permanently, which matters more on darker skin. Often combined with corticosteroid injections, which produces better results than either treatment alone.
