What actually improves scars, and which treatment fits which scar?

Scars are permanent, and most can be improved substantially. Which treatment works depends on what kind of scar it is: pitted acne scars, raised surgical scars, flat discolored marks, and wide stretched scars each respond to a different tool. Matching the treatment to the scar is the consultation.

Dr. Victoria Taraska Medically reviewed by Dr. Victoria Taraska, MD, FRCPC

Every scar is the skin’s repair job, done quickly and without much regard for how it looks. The collagen laid down in a wound is disorganized, which is why scars are a different texture and color from the skin around them, and why they do not go away. What has changed in the last decade is how much they can be improved, provided the treatment fits the scar.

Four kinds of scar

Pitted or depressed scars, most often from acne but also from chickenpox or injury, are areas where collagen was lost and the surface sank. Raised scars are areas where too much collagen formed; keloids are the extreme, growing beyond the wound. Flat discolored marks, red or brown, are scars where the texture has healed but the color has not. Wide or stretched scars follow surgery or injury where the skin was under tension. Most scars are a mix, and the treatment plan is a mix too.

Rebuilding depressed scars

Microneedling creates thousands of controlled micro-injuries that trigger new, better-organized collagen in the scar over a series of three to six sessions. It softens rolling and boxcar scars, blends the edges of pits, and works on every skin tone with a day or two of redness. Fractional laser resurfacing removes columns of scar tissue and stimulates deeper remodeling, with stronger results per session for older, deeper, or surgical scars and more downtime to match. For individual deep scars with a defined floor, a small amount of filler lifts the depression immediately and is often combined with either. Chemical peels belong on this list too: medium-depth peels such as Jessner’s, TCA, or glycolic acid followed by TCA improve acne scarring over a series, modified phenol peels are an excellent treatment for acne scars, and the CROSS technique (chemical reconstruction of skin scars) places a drop of high-strength TCA or phenol into each ice-pick scar to rebuild it from the base. Subcision, which releases the fibrous band tethering a rolling scar, and biostimulatory fillers such as Sculptra round out the options. There are many, and the right one depends on the scar.

Clearing the color

Red marks, common after acne and surgery, fade on their own over a year and faster with light-based treatment that targets the blood in the mark. Brown marks, more common on deeper skin tones, respond to a series of gentle chemical peels and prescription brighteners, with strict sun protection, since sun darkens a healing scar more than almost anything.

Raised scars and keloids

Raised scars respond to steroid injections, silicone, and specific laser settings, and keloids need a dermatologist before any cosmetic treatment, because the wrong approach makes them grow. A clinic that recognizes a keloid and refers it is a clinic that knows scars.

Timing and sun

Silicone gel or sheets and daily sunscreen from the day a wound closes do more for a new scar than most people realize. Active treatment usually waits for the scar to mature, a few months, though early laser treatment of surgical scars is increasingly standard. Ask the surgeon who made the incision; many now plan scar care into recovery.

How to choose a provider

Ask the provider to name the type of scar you have and the treatment that fits it before quoting a series. Ask to see results on your scar type and skin tone at three months after the final session. Ask what they do with a keloid. And ask for the total series price, because scar work is a series and a single session number tells you little.

Treatments for scars, compared

Best-first, with honest notes on when each is the right call.

Treatment Typical cost Downtime When it's the right call
Microneedling $200–$700 per session 1–2 days of redness, similar to a mild sunburn First-line for pitted and rolling scars, including acne scarring. Collagen remodeling over three to six sessions softens depressions and blends edges. Safe on every skin tone.
Laser Skin Resurfacing $500–$3,500 per session 1–2 days (non-ablative) up to 1–2 weeks (ablative) The strongest option for textured scars, surgical scars, and old acne scarring. Fractional lasers rebuild the surface aggressively, with real downtime and stronger results per session.
BBL Photofacial $400–$900 per session 1–3 days of redness; brown spots darken then flake off over 7–14 days For the red or brown marks scars leave behind rather than the texture. Light treatment clears the color over a few sessions.
Dermal Fillers $600–$1,500 per syringe 1–3 days of mild swelling or bruising For deep, defined depressed scars, a small amount of filler lifts the floor of the scar immediately. Often combined with microneedling or laser.
Chemical Peel $100–$600 per session A few hours (light), about a week (medium), about 2 weeks (deep) Medium-depth peels (Jessner's, TCA, glycolic acid with TCA) improve texture and discoloration over a series, and modified phenol peels and the CROSS technique (a drop of strong TCA or phenol placed into each ice-pick scar) treat deeper acne scars in experienced hands.
FAQ

Scars: common questions

Can scars be removed completely?

No scar treatment removes a scar; every one improves it. The realistic goal is a scar that is flatter, closer in color to the surrounding skin, and hard to notice at conversational distance. Pitted acne scars and surgical lines often improve by more than half over a series. Anyone promising scar-free skin is overpromising.

What about raised or keloid scars?

Raised scars, and especially keloids that grow beyond the original wound, are a dermatologist's territory before they are a clinic's. Steroid injections, silicone, pressure, and specific laser settings are the tools, and treating a keloid with the wrong resurfacing can make it worse. A clinic worth choosing will send a keloid to a dermatologist rather than attempt it.

How soon after surgery or injury can a scar be treated?

Silicone sheets or gel and strict sun protection can start once the wound has closed, and they do more for a new scar than people expect. Microneedling and laser usually wait until the scar has matured for a few months, though early laser treatment of surgical scars is increasingly used. Ask the surgeon who made the incision what timing they recommend; many now build scar care into recovery.
