In short. Melasma treatment is a ladder, and the correct place to start is almost always the bottom. First identify and reduce the triggers, then protect daily against ultraviolet and visible light. Topicals come next, judged over three months. Peels and light-based treatment come after the diagnosis and triggers are settled, because aggressive treatment can make melasma darker.
Key points
- Start with triggers and protection, not laser.
- Topicals work over months, better in combination, and hold only while used.
- Peels are an addition, kept gentle and spaced.
- Light-based treatment can improve or worsen melasma.
- The endpoint is maintenance, not cure.
What does the ladder look like?
| Step | What it is | What it achieves | Main risk |
|---|---|---|---|
| 1 | Identify and reduce triggers | Less ongoing darkening | None |
| 2 | Daily UV and visible-light protection | Holds every step above | None |
| 3 | Topical routine | Gradual lightening over months | Irritation if too aggressive |
| 4 | Gentle peels | Surface pigment as an addition | Irritation, rebound |
| 5 | Light-based treatment | Selected improvement | Rebound darkening |
| 6 | Maintenance | Keeps the result | Stopping causes return |
Why start at the bottom?
A face that is still being darkened by exposure cannot be lightened faster than it is being darkened, and a face irritated by an aggressive procedure holds pigment longer. The lower steps are not a formality before the real treatment; they are what allows any treatment above them to hold.
What does protection involve?
Broad-spectrum sun protection applied generously and repeated through the day, plus a tinted product that also blocks visible light, a hat, and avoiding the middle of the day where possible. It also means thinking about heat and hormones. This step costs little, never stops, and decides the long-term result more than anything above it.
How long before judging a topical?
Months, not weeks. Topical retinoids, azelaic acid, hydroquinone, niacinamide, vitamin C, and cysteamine are the substance classes used. They work slowly, better in combination than alone, and hold improvement only while used. Three months of consistent use is a reasonable review point, against photographs in the same light.
What about peels and light?
Chemical peels using glycolic, mandelic, lactic, or salicylic acid can lift surface pigment as an addition to a topical routine, provided they are gentle and widely spaced. Light-based treatment, including intense pulsed light and laser, can improve melasma and can also make it worse: inflammation from an aggressive setting can bring patches back darker, particularly in darker skin. It is a decision for someone who treats melasma regularly, after diagnosis and triggers are settled, often after a test area.
When should the ladder stop?
When the patches have lightened as far as they will go and two reviews in a row show no further change. At that point, hold the result with maintenance rather than add another procedure. Continuing to escalate against a plateau is how people acquire irritation and rebound darkening without a better result.
When should a doctor be involved?
- Laser is offered as a first step, before diagnosis and triggers are settled.
- A clinic proposes peels, laser, and microneedling within the same few weeks.
- A fixed package is sold before anyone has examined the skin.

Frequently asked questions
Can I skip the early steps and go straight to laser?
You can, and it usually goes badly. Light-based treatment on a face that is still being driven by exposure or hormones tends to darken again, and aggressive settings can cause rebound darkening that outlasts any benefit. The lower steps are not a waiting period; they are what makes the higher steps hold.
How long before I can judge whether a topical is working?
Months, not weeks. Topical agents lighten melasma gradually, and the judgement should be made against photographs taken in the same light at the same angle. A reasonable review point is around three months of consistent use. If a product is claimed to work in a fortnight, it is either an irritant or it contains something that should not be on your face.
How do I know when to stop climbing the ladder?
When the patches have lightened as far as they will go and two reviews in a row show no further change. At that point the sensible move is to hold the result with maintenance rather than to add another procedure. Continuing to escalate treatment against a plateau is how people acquire irritation and rebound darkening without acquiring a better result.
Risks & Limitations
- Melasma is chronic and relapsing. Treatment lightens it and maintenance keeps it lighter; it does not cure it.
- Sunlight and visible light can bring the patches back after a good result, so photoprotection is permanent.
- Aggressive laser treatment can worsen melasma and cause rebound darkening in some patients.
- Pregnancy, breastfeeding and hormonal treatment change what is safe, and must be discussed before any plan starts.
When to Seek Care
- A pigmented patch that is new, changing, asymmetrical or bleeding needs assessment to exclude other diagnoses.
- Darkening is rapid, or follows a new medicine or hormonal treatment.
- Skin becomes inflamed, blistered or persistently red after a lightening product or procedure.
- Pigmentation appears with fatigue, weight change or other general symptoms.
