Melasma recurs because it is a chronic, relapsing condition driven by ongoing triggers — ultraviolet and visible light, heat, hormonal factors and inflammation — rather than a stain that can be removed once. Sun protection is the single most important factor in keeping it controlled. Aggressive laser treatment can make melasma worse, particularly on brown skin, by provoking rebound pigmentation. Treatment aims at long-term control, not a permanent cure, and any clinic promising one is overstating what is achievable.
Why does melasma come back after treatment?
Because the pigment you can see is a symptom, not the disease. Melasma involves pigment-producing cells that are overactive and remain sensitive to their triggers even after the visible discolouration has faded. Remove the pigment without changing the triggers and the same cells produce it again.
The main drivers are ultraviolet light, visible light — including from screens and indoor lighting — infrared heat, hormonal factors such as pregnancy and hormonal contraception, and skin inflammation from irritating products or procedures. In coastal Kerala and Karnataka, high year-round UV and ambient heat mean two of the strongest triggers are present almost daily.
When does laser make melasma worse?
Laser and energy-based treatment can worsen melasma when it delivers too much heat or too much energy into skin that is already primed to over-produce pigment. The result is rebound hyperpigmentation — the patch returns darker than before, sometimes weeks after treatment appeared successful. This risk is higher on Fitzpatrick IV to V skin, which describes most Indian patients.
Specific situations where caution is warranted:
Actively inflamed or recently irritated melasma — treating through inflammation tends to worsen it.
Aggressive settings chosen to produce fast visible clearing.
Ablative or heavily thermal devices used as a first-line approach for melasma.
Any treatment plan that has not established sun protection and topical control first.
Treatment during pregnancy or while hormonal triggers remain uncontrolled.
Repeated sessions continued despite the patch darkening after previous ones.
This does not mean lasers have no role in pigmentation. It means melasma specifically is the diagnosis where restraint matters most, and where the sequence — protect, then topical, then consider device treatment — matters more than the device itself.
Is my pigmentation actually melasma?
This matters because the conditions look similar and respond very differently. Self-diagnosis from photographs online is unreliable, and treating the wrong one wastes months.

What actually helps keep it controlled?
Daily broad-spectrum sunscreen, reapplied — the single highest-impact factor. Tinted formulations containing iron oxide also block visible light, which matters in melasma specifically.
Physical protection — hats, shade, avoiding peak sun. Relevant year-round in this climate, not seasonally.
Managing heat exposure where practical, including cooking heat and hot showers on the face.
Prescribed topical therapy, used consistently and reviewed by a doctor rather than continued indefinitely without supervision.
Reviewing hormonal contributors with your physician or gynaecologist where relevant.
Avoiding harsh scrubs, unregulated skin-lightening creams and frequent irritating procedures — inflammation is itself a trigger.
Maintenance after clearing, rather than stopping treatment the moment the skin looks better.
What should I expect from treatment realistically?
Realistic goals are meaningful lightening, slower and less frequent relapse, and a maintenance routine you can sustain. Timelines are measured in months, not weeks. Some patients achieve long stretches of near-clear skin; most will see some return with sun exposure, pregnancy or hormonal change, and will need maintenance.
Any promise of permanent removal is not consistent with how melasma behaves.
Frequently asked questions
Can melasma be cured permanently?
No. Melasma is a chronic, relapsing condition. Treatment aims at long-term control — meaningful lightening, slower relapse and a sustainable maintenance routine — rather than permanent removal. Claims of a permanent cure are not consistent with how the condition behaves.
Can laser make melasma worse?
Yes. Aggressive or heavily thermal laser treatment can provoke rebound hyperpigmentation, where the patch returns darker than before. This risk is higher on darker skin types. Sun protection and topical control are established first, and device settings kept conservative.
Why does my melasma come back every summer?
Ultraviolet and visible light are among the strongest triggers, so pigmentation commonly deepens with increased sun exposure. In coastal Kerala and Karnataka, UV levels stay high through most of the year, which is why daily sunscreen matters more than seasonal precautions.
How is melasma different from post-inflammatory hyperpigmentation?
Melasma appears as symmetrical, blended patches usually on the cheeks, forehead and upper lip, and is chronic and relapsing. Post-inflammatory hyperpigmentation follows exactly where a spot, rash or injury was, matches that shape, and usually fades over months.
Does sunscreen actually help melasma?
It is the single most important factor in keeping melasma controlled. Broad-spectrum protection applied daily and reapplied is essential, and tinted formulations containing iron oxide additionally block visible light, which is a relevant trigger in melasma specifically.
Is melasma caused by pregnancy?
Hormonal factors including pregnancy and hormonal contraception are recognised triggers, which is why melasma is sometimes called the mask of pregnancy. It can also occur without any hormonal trigger. Treatment approach differs during pregnancy and must be discussed with your doctor.

Atrophic acne scars fall into three main shapes. Icepick scars are narrow and deep, and respond best to focal techniques rather than resurfacing alone. Boxcar scars are wider with sharp vertical edges, and respond to resurfacing such as fractional CO2 laser and microneedling. Rolling scars are broad with sloping edges caused by tethering beneath the skin, and usually need that tethering released rather than surface resurfacing. Most faces have a mix, which is why single-treatment plans usually underperform.
Why does scar shape decide the treatment?
Because each shape represents a different structural problem. A narrow deep track, a sharp-walled depression and a broad tethered dip are three different anatomical situations, and a treatment that addresses one may do very little for another.
This is the most common reason patients feel a course of treatment underdelivered. They were treated for the category of acne scarring rather than for the specific scars on their face, and the scars that did not respond were the ones the chosen treatment was never going to reach.
How do I recognise each type?
Type
What it looks like
Underlying problem
Usual approach
Icepick
Small, narrow, deep — like a pinprick or a puncture
A narrow tract extending deep into the skin
Treated focally, spot by spot, rather than by resurfacing the whole face — broad resurfacing rarely reaches the base
Boxcar
Round or oval depression with sharp, steep edges
Loss of tissue with defined vertical walls
Fractional CO2 laser or microneedling, to soften the edges across a course of sessions
Rolling
Broad, shallow, wave-like undulation; skin looks uneven in raking light
Fibrous bands tethering the skin to deeper tissue
The tethering has to be released; resurfacing the surface alone under-treats these
Hypertrophic / keloid
Raised, firm, sometimes itchy — more common on jaw, chest, back
Excess collagen deposition during healing
Managed very differently — resurfacing is not the answer and can worsen them
How many sessions will I need?
For fractional resurfacing of boxcar and mixed scarring, three to six sessions spaced roughly four to eight weeks apart is a common plan, with improvement continuing for several months after the final session as collagen remodels. Rolling scars often need their tethering addressed in one to three procedures before resurfacing adds much. Icepick scars are typically treated focally over repeated visits.
Honest framing: acne scar treatment produces improvement, not erasure. A realistic goal is meaningful softening of texture and shadow so that scars become far less noticeable in normal light. Complete restoration to pre-acne skin is not an outcome any clinic can promise.

What actually decides the cost of acne scar treatment
We do not publish rates, because a figure quoted before anyone has looked at your skin is guesswork. What we do commit to is that the full cost is itemised and agreed with you at consultation, before any treatment begins, with nothing added afterwards.
What are the risks on Indian skin?
The main concern with resurfacing on Fitzpatrick IV to V skin is post-inflammatory hyperpigmentation — darkening of the treated area during healing. It is usually temporary but can take weeks to months to settle, and it is the reason conservative settings, careful patient selection and strict aftercare matter more here than in lighter skin.
Post-inflammatory hyperpigmentation — the most common issue; minimised by conservative settings, sun avoidance and pre-treatment preparation of the skin.
Prolonged redness after fractional resurfacing — expected for days, occasionally longer.
Infection or delayed healing — uncommon, but why aftercare instructions are specific rather than general.
Worsening of raised scarring in keloid-prone individuals.
Active acne must be controlled before scar treatment begins — treating scars while acne is active means creating new ones.
What should I ask at consultation?
Which scar types do I actually have, and can you show me on my own face?
Which of my scars will this treatment help, and which will it not?
How many sessions before we reassess, and what will we do if response is poor?
What is the plan if I develop pigmentation afterwards?
Does my acne need to be controlled first?
Frequently asked questions
What are the different types of acne scars?
Depressed (atrophic) acne scars are usually grouped as icepick — narrow and deep; boxcar — wider with sharp vertical edges; and rolling — broad and shallow with sloping edges caused by tethering beneath the skin. Raised hypertrophic and keloid scars are a separate category treated very differently.
Which treatment is best for rolling acne scars?
Rolling scars are caused by fibrous bands tethering the skin to deeper tissue, so they generally need that tethering released rather than surface resurfacing alone. Resurfacing may be added afterwards, but used by itself it commonly under-treats this scar type.
How many CO2 laser sessions do I need for acne scars?
CO2 laser for acne scars is given as a course spaced weeks apart, with improvement continuing for months afterwards as collagen remodels. The number of sessions depends on your scar type, depth and how your skin responds, and is decided after assessment rather than promised in advance.
Can acne scars be removed completely?
No. Acne scar treatment produces improvement rather than erasure. A realistic goal is meaningful softening of texture and shadow so scars become far less noticeable in normal light. Complete restoration to pre-acne skin is not an achievable promise.
Is CO2 laser safe for Indian skin?
It is used on Indian skin, with the main concern being post-inflammatory hyperpigmentation during healing. This risk is managed with conservative settings, preparation of the skin beforehand, strict sun avoidance and careful patient selection. Suitability is assessed individually.
Should I treat active acne before treating scars?
Yes. Active acne needs to be controlled first. Treating scars while acne is still active risks creating new scars, and inflamed skin responds less predictably to resurfacing.
What does acne scar treatment cost in Kochi or Calicut?
Cost is driven by which scar types you have, how large an area needs treating, which treatment is chosen and how long the course runs. Treating a few individual deep scars costs far less than resurfacing a full face. We give you the complete figure at consultation, itemised, once your skin has been examined.
