Acne Scars: Types, Treatments and a Realistic Timeline

Acne can leave two kinds of reminders. Some are flat dark spots that fade over months. Others are dips, pits and uneven texture that stay long after the last breakout. The second kind, acne scars, affect how light falls on the skin, so they show up in selfies and harsh office lighting even when the skin tone is even.

The good news is that acne scars can be improved a great deal. The key is knowing which type of scar you have, because each type responds to a different treatment. This guide explains the types, the treatments that work, a realistic timeline, and what you can do to avoid new scars. It is written by the team at Dr. K Skin Hair Advance Laser Clinic in Charni Road.

Acne marks vs acne scars

This is the most important distinction, because it decides the whole plan.

On Indian skin, brown marks after acne, called post-inflammatory hyperpigmentation, are very common and are often mistaken for scars. The good news is that marks respond much faster than true scars.

Why acne scars form

A deep, inflamed pimple damages the skin below the surface. As it heals, the body repairs the damage with collagen. If too little collagen is made, the skin dips, and you get an atrophic, or depressed, scar. If too much is made, you get a raised scar.

Scarring is more likely when:

• acne is deep, cystic or nodular,
• acne goes untreated for a long time,
• pimples are squeezed or picked,
• there is a family tendency to scar.

This is why early acne treatment is the best scar prevention there is.

The types of acne scars

Most people have a mix of types. Knowing them helps you understand why one treatment alone rarely gives the full result.

Ice pick scars

Narrow, deep pits that look like the skin was pierced with a sharp tool. They are deeper than they are wide, and they are the most common type of depressed acne scar. Because they go deep, surface treatments cannot reach their base, which makes them among the hardest to treat.

Boxcar scars

Round or oval dips with sharp, well-defined edges, a bit like chickenpox scars. They are wider than ice pick scars and can be shallow or deep. They are common on the cheeks and temples.

Rolling scars

Broad dips with soft, sloping edges that make the skin look wavy or uneven, especially in side light. They are caused by bands of fibrous tissue under the skin that tether the surface down.

Raised scars (hypertrophic and keloid)

Firm, raised scars, more common on the jawline, chest, back and shoulders. Keloids grow beyond the original spot and need a different approach, often injections and pressure, rather than resurfacing.

The treatments that work

Microneedling

Fine needles make tiny, controlled channels in the skin. The skin responds by producing new collagen and elastin, which gradually lifts shallow scars and improves texture. Because it does not depend on heat, microneedling is considered safe for all skin tones, which makes it one of the most useful scar treatments for Indian skin.

It is often combined with PRP (platelet-rich plasma from your own blood) or growth-factor serums to support healing. Expect some redness for a day or two.

Fractional laser resurfacing

A fractional laser creates tiny columns of controlled injury in the skin, leaving the skin between them intact so it heals quickly. This triggers new collagen and elastin, which can soften the look of scars and improve texture. On brown skin, settings are chosen carefully to lower the risk of pigmentation, and sun protection before and after is essential.

Subcision

A fine needle is passed under a rolling scar to cut the fibrous bands that pull the skin down. Once released, the skin can rise, and new collagen forms underneath. Subcision is particularly useful for rolling scars, which surface treatments alone often cannot fix.

TCA CROSS

For ice pick scars, a small amount of a stronger acid (trichloroacetic acid) is placed precisely into each pit with a fine applicator. This triggers collagen inside the scar so it gradually fills from the base up. It is a targeted technique done by a doctor, scar by scar.

Chemical peels

Peels help with marks, uneven tone and mild texture. For shallow scars, a series of peels can smooth the surface. They are often used between other treatments to keep tone even. Read more in our guide to chemical peels.

Dermal fillers

For a few deep, soft scars, a small amount of hyaluronic acid filler can lift the dip immediately. The effect is temporary, but it can be a useful quick improvement, for example before an event, while longer-term treatments work.

Matching the treatment to the scar

This is why a consultation matters. Two people who both say "I have acne scars" can need completely different plans.

A realistic timeline

Scar treatment is gradual. Collagen takes weeks to form and months to mature, so results keep improving for some time after each session.

1. Month 0: consultation, photos, control of any active acne, and preparing the skin with sun protection and creams.
2. Months 1 to 2: the first 2 to 3 sessions. Texture starts to soften, but changes are subtle.
3. Months 3 to 4: sessions 4 to 6. Most people see a clear improvement in photos taken in the same light.
4. Months 5 to 6 and beyond: further sessions for deeper scars, then collagen keeps building for a few months after the last one.

Most people need 4 to 8 sittings over 3 to 6 months. Deeper or more widespread scarring can need more. A clear, visible improvement is a realistic goal for most people. Complete removal is rare, and anyone promising it should be asked how they measure it.

What to expect after treatment

• Microneedling: redness like mild sunburn for 1 to 2 days; makeup can usually be used after 24 hours.
• Fractional laser: redness, swelling and a sandpaper feel for a few days; small dots may flake off.
• Subcision: some swelling and bruising for about a week.
• TCA CROSS: the treated pits turn white, then form small dark crusts that fall off in about a week.

After any of these, gentle skincare, no picking, and strict sun protection help the skin heal evenly.

Preventing new scars

Treating scars while new ones are forming is like painting a wall with a leak behind it. These steps matter as much as the treatment itself:

1. Get acne under control early. Especially deep or painful pimples. See our acne treatment page for how we approach active acne.
2. Do not squeeze or pick. It pushes inflammation deeper and increases scarring.
3. Use sunscreen daily. Sun darkens marks and makes scars look more obvious.
4. Be patient with marks. Most flat marks fade with time and the right care; they are not permanent scars.
5. Treat hormonal acne at its cause. Acne along the jawline in adult women often has a hormonal link that needs to be addressed.

Acne scar treatment for Indian skin

Brown skin heals with a higher risk of pigmentation after any injury, including treatment. That does not rule out scar treatment; it shapes how it is done:

• Preparing the skin with sunscreen and lightening creams for 2 to 4 weeks before stronger treatments.
• Choosing microneedling and subcision, which carry a lower risk of pigmentation, as the backbone.
• Using lasers at settings chosen for darker skin, with adequate gaps between sessions.
• Treating any pigmentation that appears promptly, before it settles.

Can home products fix acne scars?

Home products can help marks and overall texture, but they cannot rebuild collagen deep enough to lift true scars.

• Helpful: sunscreen, retinoids (as advised), niacinamide, azelaic acid and vitamin C for marks and tone.
• Not helpful: scrubs, lemon juice, bleaching creams, and at-home dermarollers used without supervision. Home rollers can spread infection and cause pigmentation if used incorrectly.

Scars in different areas

Where the scars are changes the plan, because skin thickness and healing vary across the face and body.

Cheeks. The most common area for boxcar and rolling scars. The skin is thick enough for most treatments, and cheeks usually show the most visible improvement.

Temples and forehead. The skin is thinner and closer to bone. Scars here are often shallower but need gentler settings.

Jawline and chin. Often linked to hormonal acne in adult women. Scars here can be a mix of ice pick scars and dark marks, and raised scars are more likely than on the cheeks.

Nose. Enlarged pores and small pitted scars are common. They respond to peels and careful resurfacing.

Back, chest and shoulders. More prone to raised and keloid scars. Resurfacing is done cautiously here, and raised scars are flattened first.

What decides the cost of acne scar treatment

Scar treatment is a course rather than a single session, so it helps to understand what drives the total.

1. The number and depth of scars. A few shallow scars need fewer sessions than widespread deep scarring.
2. The types of scars. A mix of ice pick, boxcar and rolling scars usually needs a combination of techniques.
3. The treatments used. Microneedling, peels and lasers are priced differently, and techniques like subcision or TCA CROSS are done scar by scar.
4. The area treated. Full face costs more than cheeks only.
5. Maintenance of acne. If acne is still active, treating it adds to the plan but saves money in the long run by preventing new scars.

Ask for a written plan with the number of sessions and the total cost before you begin.

Living with scars while you treat them

Treatment takes months, and scars can affect confidence during that time. A few practical things help:

• Makeup is fine between sessions once the skin has settled, usually after 24 to 48 hours for microneedling. A primer designed to fill texture can make scars less visible.
• Lighting changes everything. Scars look worse under overhead light and better in soft, front-facing light. This is also why progress photos are always taken in the same light.
• Focus on the trend, not the day. Skin looks different from day to day. Compare photos every 4 to 6 weeks rather than checking the mirror daily.
• Talk to us if it is affecting you. Acne and scarring can weigh on mood and confidence. That is a valid reason to start treatment, and a reason to ask for support if you need it.

Questions to ask before you start

• Which types of scars do I have?
• Which treatments will you combine, and why?
• How many sessions do you expect, and over how long?
• What downtime should I plan for after each session?
• What result is realistic for my skin?
• How will we measure progress?

A good clinic answers all of these before you pay for a course.
