Melasma Management: What Should You Know First?
If you have stood in front of the mirror studying brown patches above your cheekbones and wondered, "Can I do something about this melasma?" — you are not alone. A quick online search turns up everything from lasers to creams to in-clinic procedures, yet it is rarely clear which option is right for your particular melasma, or how much improvement is realistically achievable.
Let us be upfront about something important. Unlike a mole or a simple dark spot, melasma is a pigmentary condition rooted in multiple overlapping causes — and it tends to darken again once active management stops. That is why the realistic perspective is not "erase it completely" but rather fade it and keep it from returning through long-term management. This article draws on verified medical evidence and the clinical approach of Dr. Kim Gun-woo, Medical Director of Cellinique on Dosan-daero, Gangnam, to walk you through what melasma is, how it is managed, and what to expect.
3-Line Summary
1. Melasma arises from excess melanin production driven by a combination of UV radiation, visible light, female hormones (estrogen), and genetic predisposition. Of these, UV exposure is reported as the most important aggravating factor.
2. Management involves a stepwise combination of broad-spectrum sun protection + topical brightening treatment + laser modalities (laser toning, pico toning). Laser therapy alone carries a high recurrence rate, and excessive treatment has been associated with side effects such as punctate hypopigmentation (white spots).
3. Melasma is a recurrent, refractory condition for which a complete cure cannot be promised. Response and recurrence patterns vary considerably between individuals; a personalized plan is established through pre-treatment consultation.
1. Why Does Melasma Develop? — Melanin, UV, and Hormones
Melasma is a brown-to-grayish-brown pigmentation that typically appears symmetrically across both cheeks, cheekbones, forehead, and the bridge of the nose. The central mechanism is that the skin's pigment-producing cells (melanocytes) overproduce melanin. What makes melasma particularly challenging is that this overproduction is driven not by a single trigger but by several factors working in concert.
The Main Causes Are Intertwined
- UV radiation and visible light (sunlight) — The most important aggravating factor. Not only UVB and UVA, but also visible light (VL) has been reported to stimulate melanocytes.
- Female hormones — Estrogen and progesterone are involved in melanin production. Pregnancy, oral contraceptive use, and hormonal changes are known to trigger or worsen melasma.
- Genetics and skin type — Family history and individual skin type influence susceptibility.
- Skin barrier disruption, heat, and irritation — Repeated irritation, heat exposure, and certain cosmetics or procedures can also contribute to deeper pigmentation.

- Melasma is described as a multifactorial pigmentary condition in which genetics, female hormones, and sun exposure interact.
- Daily sun exposure is the most important factor in its onset and aggravation; not only UVB and UVA but also visible light (VL) has been reported to stimulate melanin production.
- The degree of onset and subsequent course vary considerably between individuals.
An important implication follows. Because the causes are multiple, a single-modality approach is often insufficient, and failing to address the primary driver — sun exposure — means pigment tends to return regardless of what other treatment is applied. That is why melasma management is best understood not as a "one-shot fix" but as a stepwise, multi-modal process managed over time.
Key Takeaway
Melasma results from excess melanin production, with UV radiation, visible light, female hormones, and genetic factors all contributing. Because the causes are multifactorial, management must be multifactorial as well.
2. Melasma Management Options — Where Do You Begin?
Melasma care generally follows a stepwise progression: foundation → topical treatment → procedures. The reason for this sequence is that without the foundational layer of sun protection, procedures tend to yield short-lived results and pigmentation returns more readily.
| Step | Approach | Role |
|---|---|---|
| Step 1 · Foundation | Broad-spectrum sun protection, lifestyle adjustments | The basis of all treatment — skipping it raises recurrence risk |
| Step 2 · Topical Treatment | Brightening agents (hydroquinone, retinoids, etc. — by prescription) | Suppress melanin production — commonly used as first-line therapy |
| Step 3 · Procedures | Laser toning, pico toning, etc. (adjunctive approach) | Fade pigmentation — used in combination rather than alone, at conservative settings |
Medical literature commonly positions broad-spectrum sunscreen and topical brightening agents (hydroquinone, retinoids, glycolic acid, etc.) as first-line therapy, with laser as an adjunctive treatment. In other words, laser is less a tool to "eliminate melasma in one session" and more an option layered on top of foundational management.
2-1. Sun Protection — The Single Most Fundamental Step
As discussed above, sunlight is the most important aggravating factor for melasma. Sun protection is therefore not an optional add-on but the foundation of melasma management. Applying a broad-spectrum sunscreen generously and frequently — one that addresses not only UVA and UVB but also visible light — is the recommended approach.

- Because sunlight is the primary stimulus for pigmentation, consistent use of a high-SPF broad-spectrum sunscreen is described as the cornerstone of management.
- Photoprotection that addresses visible light (VL) in addition to UV has been reported to improve clinical outcomes.
- Hormonal factors such as oral contraceptive use and menopausal hormonal changes are also recognized aggravating contributors, though the extent varies between individuals.
2-2. Topical Brightening Treatment — Commonly Used as First-Line Therapy
Topical agents that suppress melanin production — such as hydroquinone and retinoids — are common first-line treatments for melasma. However, depending on concentration, duration of use, and combination regimens, reactions such as irritation or post-inflammatory hyperpigmentation can occur. It is therefore essential to have a physician prescribe and adjust the regimen to suit your individual skin. Self-directed long-term use of high-potency brightening ingredients is not recommended.
3. Laser Toning and Pico Toning — How Much Can Procedures Help?
You have likely heard the phrase "laser toning for melasma." At Cellinique, laser toning or pico toning may be considered as part of a melasma consultation. Before recommending any procedure, however, we make it a priority to first discuss expectations honestly, including the limitations.
Laser Toning (Low-Fluence Q-Switched Nd:YAG)
Laser toning uses a low-fluence 1064 nm Nd:YAG laser delivered in multiple passes to gradually fade melanin. The key is not a single high-energy session but repeated low-energy treatments spaced at regular intervals.
💡 Fact-check ✓
Source: Systematic review of low-fluence Q-switched Nd:YAG laser for melasma (Medicina (Kaunas), 2022, 42 studies, 1,736 patients; PMC9323185)
- Low-fluence Q-switched Nd:YAG laser is described as generally effective and relatively safe for melasma, but long-term follow-up data remain limited.
- Recurrence is common: one study reported approximately 58.8% recurrence at one year (results vary across studies).
- Excessive cumulative energy (high fluence, short intervals, too many sessions) is associated with a risk of side effects such as punctate hypopigmentation (white spots), and combination therapy is recommended over laser alone. Outcomes and side effects vary between individuals.
Pico Toning (Picosecond Laser)
Pico toning addresses pigmentation using laser pulses measured in picoseconds. The ultra-short pulse width is designed to minimize thermal damage to surrounding tissue, making it one option considered for melasma as well. However, recurrence has also been reported with pico toning, and no laser modality offers a "one-and-done" solution for melasma.

Source: Randomized evaluator-blinded trial comparing picosecond alexandrite vs. combined Q-switched/long-pulse Nd:YAG for melasma (Lasers in Medical Science, 2025; PMC11754324)
- Both picosecond laser and combined Q-switched/long-pulse Nd:YAG are used for melasma, and their safety profiles were reported as broadly similar.
- At 24 weeks, recurrence was 10.5% for the picosecond alexandrite arm and 0% for the combined Nd:YAG arm, but the difference was not statistically significant (P = 0.486).
- Reported procedural side effects included transient erythema, pruritus, and post-inflammatory hyperpigmentation. Results vary between individuals.
| Category | Laser Toning (Low-Fluence Nd:YAG) | Pico Toning (Picosecond Laser) |
|---|---|---|
| Approach | Multiple low-fluence passes to gradually fade melanin | Ultra-short picosecond pulses to break up pigment |
| Role | Common adjunctive procedure for melasma | An option considered for pigmentation and melasma |
| Limitations | Frequent recurrence; risk of hypopigmentation with overtreatment | Recurrence reported; transient irritation reactions possible |
| Shared Principle | Used in combination with sun protection and topical therapy rather than alone; conservative settings; individualized planning | |
The key point is this: laser is an addition, not the whole answer. For melasma, the more stable approach is to use laser as a supplement to the foundation of sun protection and topical treatment, at conservative fluences and intervals. This is precisely why Cellinique designs melasma procedures conservatively.
4. How Does Cellinique Approach Melasma?
Cellinique is an anti-aging dermatology clinic on Dosan-daero, Gangnam-gu. For pigmentary conditions like melasma — where causes are complex and recurrence is common — rather than pushing a single procedure, we aim to maintain a clear and stable flow: pre-treatment assessment → foundational management (sun protection + topical) → adjunctive procedures → follow-up review.
- Pre-treatment consultation and skin assessment — Dr. Kim Gun-woo personally reviews the depth and extent of pigmentation, aggravating factors (sun exposure, hormonal changes, prior treatment history), and lifestyle. The starting point is confirming whether the condition is truly melasma or another form of pigmentation.
- Foundational care guidance — We first establish the basics: sun protection and topical treatment. Without this foundation, procedures are more likely to be followed by recurrence.
- Adjunctive procedure planning — When indicated, laser toning or pico toning may be reviewed at conservative fluences and intervals. Aggressive settings are avoided because they increase the risk of side effects.
- Follow-up and recurrence management — Because melasma can darken again once management lapses, we monitor changes over time and develop a long-term maintenance plan together.
💡 A note from our practice — Patients consulting about melasma often ask, "How many laser sessions until it clears up?" When we explain upfront that the goal is to fade pigmentation and prevent it from deepening again over the long term — rather than to eliminate it outright — most patients tend to receive the results more calmly. That said, individual courses vary considerably, so please reach out to Cellinique whenever you notice a change.

Side effects, emergency responses, and contraindications that apply across all procedures at Cellinique are detailed on the Cellinique Procedure Safety Information page.
5. Important Precautions to Keep in Mind for Melasma Management
With melasma, "avoiding aggravation" and "managing recurrence" matter just as much as achieving improvement. The points below are consistently emphasized in both medical literature and clinical practice.
Please Note
- Never skip sun protection — Visible light can act even on cloudy days and indoors, so consistent broad-spectrum photoprotection is the foundation.
- Avoid excessive laser treatment and strong irritants — Excessive cumulative energy is associated with side effects such as punctate hypopigmentation (white spots). "High intensity, high frequency" is not the right approach.
- Do not self-apply potent brightening agents long-term — Prolonged self-directed use of high-strength brightening ingredients can trigger irritation and pigmentation changes; use only under physician supervision.
- Plan for long-term management with recurrence in mind — Even after improvement, abruptly stopping management can cause pigmentation to deepen again.
When to See a Physician
- If pigmentation darkens rapidly or changes in shape or border in an unusual way
- If you are pregnant, breastfeeding, or taking hormonal medications (such as oral contraceptives)
- If you experience irritation, white spots, or pigmentation changes following a prior procedure or topical treatment
If any of the above applies to you, seeking a professional consultation to assess the type and condition of your pigmentation is safer than attempting a stronger approach on your own.
Frequently Asked Questions (FAQ)
Q1. Can laser completely remove melasma?
Unlike moles or simple dark spots, melasma is a pigmentary condition characterized by frequent recurrence and a refractory nature — a complete cure cannot be promised. Laser can help fade pigmentation, but medical literature also reports that laser therapy alone is associated with frequent recurrence. The realistic perspective is therefore not "eliminate it" but fade it and manage it long-term to prevent deepening. Individual results vary considerably.
Q2. Where should I start with melasma management?
The very first step is sun protection. Since sunlight is the most important aggravating factor for melasma, consistent use of a broad-spectrum sunscreen is the foundation for all treatment. From there, the next step is physician-prescribed topical brightening therapy, followed by adjunctive procedures such as laser toning or pico toning when needed. The sequence is tailored to your individual condition during the initial consultation.
Q3. What is the difference between laser toning and pico toning?
Laser toning uses low-fluence Nd:YAG laser energy delivered in multiple passes to gradually fade melanin. Pico toning uses ultra-short picosecond pulses to address pigmentation. Both are options considered for melasma, and both have reported limitations including recurrence and irritation reactions. Which approach is most appropriate depends on the depth and condition of your pigmentation and is determined through pre-treatment consultation.
Q4. What side effects can occur with laser treatment?
Reported side effects include transient erythema, pruritus, and post-inflammatory hyperpigmentation. In particular, excessive cumulative energy (high fluence, short intervals, too many sessions) is associated with a risk of side effects such as punctate hypopigmentation (white spots). For this reason, Cellinique uses conservative fluences and intervals, and recommends combining laser with sun protection and topical therapy rather than using laser alone. The likelihood and severity of side effects vary between individuals.
Q5. Do I need to continue management even after melasma improves?
Yes. Melasma is a condition that tends to darken again once active management stops. Recurrence is particularly common when sun protection is neglected or when hormonal changes occur, so it is advisable to maintain protective habits and ongoing management even after improvement. We provide guidance on a long-term maintenance plan during follow-up reviews.
Q6. Can I receive treatment if I am pregnant or taking hormonal medications?
If you are pregnant, breastfeeding, or taking hormonal medications such as oral contraceptives, it is important to note that hormonal factors are a known background contributor to melasma. The decision about whether and how to proceed requires careful judgment. Rather than deciding on your own, please be sure to disclose this during your pre-treatment consultation so we can assess your situation together.
Q7. Can I come in for a consultation only?
Of course. Since the approach to melasma differs depending on the type and depth of pigmentation, we encourage you to first understand your own condition through a consultation before making any decisions. Whether or not you proceed with a procedure, if you would like a consultation only, please contact us at 02-6203-3434 or via KakaoTalk. (Consultation and procedure fees vary by individual condition and treatment plan and will be explained during your consultation.)
Closing
Managing melasma is not a magic one-time fix. It is a process of blocking its primary driver — sunlight; controlling melanin with topical treatment; adding laser support when needed; and committing to long-term management with recurrence built into the expectation. Laser toning and pico toning can be helpful options within that framework, but aggressive settings can cause side effects such as white spots, which is why a conservative approach matters.
At Cellinique (Gangnam, Dosan-daero), Dr. Kim Gun-woo personally oversees the full process — from cause assessment and foundational care to adjunctive procedures and follow-up review. If you are concerned about melasma, we encourage you to start with a conversation: a consultation to comfortably discuss the condition and aggravating factors of your own pigmentation.
