What Is Melasma?
Melasma presents as symmetrical patches of hyperpigmentation, most commonly appearing on the cheeks, forehead, upper lip, and chin. Though it’s more prevalent in women and those with darker skin types, melasma can affect anyone. The condition is aggravated by certain triggers and tends to recur even after seemingly successful treatment.
Primary Causes of Melasma
- Sun exposure: Ultraviolet (UV) light stimulates melanocytes, the cells that produce pigment, causing melasma to worsen.
- Hormonal changes: Pregnancy, birth control pills, and hormonal therapy are common triggers.
- Genetics: Family history plays a significant role in susceptibility.
- Skin irritation: Overuse of harsh products or procedures can worsen discoloration.
It’s important to note that melasma is not an infection and is rarely linked to internal disease.
First-Line Topical Treatments
Dermatologists often recommend topical agents as the starting point for controlled, gradual improvement. Here are the top options:
- Hydroquinone:
- Considered the gold standard for melasma.
- Works by inhibiting melanin production.
- Available in prescription (2–4%) or over-the-counter (lower strengths) creams.
- Side effects may include irritation, contact dermatitis, and rarely, ochronosis (blue-black pigmentation with prolonged use).
- Triple Combination Cream (TCC):
- Blends hydroquinone, a retinoid (usually tretinoin), and a mild corticosteroid.
- Delivers superior results while minimizing irritation risk.
- Clinical evidence demonstrates significant pigment reduction for most patients.
- Tretinoin (Retinoid):
- Powers cell turnover and pigment dispersal.
- Often included in combination creams.
- Azelaic Acid:
- Gentler alternative with pigment-inhibiting properties.
- Well tolerated by sensitive skin types.
- Topical Vitamin C:
- Known for antioxidant benefits and brightening effect.
- Topical Tranexamic Acid:
- Blocks UV-induced pigment pathways.
- Increasingly popular in both prescription and over-the-counter formats.
Comparative Overview: Topical Therapies
| Agent | Efficacy | Common Side Effects | Ideal Use |
|---|---|---|---|
| Hydroquinone | High | Irritation, ochronosis (rare) | Short-term cycles, combo creams |
| Triple Combination Cream (TCC) | Very high | Mild irritation | Most cases, dermatologist-monitored |
| Tretinoin | Modest | Dryness, peeling | With other agents |
| Azelaic Acid | Moderate | Mild irritation | Sensitive skin types |
| Vitamin C | Low to moderate | Stinging | Maintenance, adjunct |
| Topical Tranexamic Acid | Moderate | Mild | Both prevention & management |
Advanced Procedures and Combination Therapies
If topical solutions aren’t enough, dermatologists turn to more intensive options. It’s critical to proceed under medical supervision to minimize risks.
- Laser Treatments:
- Q-switched Nd:YAG laser (QSND):
- Highly effective, especially compared to hydroquinone or topical tranexamic acid.
- Risks include post-inflammatory hyperpigmentation, particularly in darker skin types.
- Ablative Fractional Laser (AFL):
- Fractional CO2 or Er:YAG lasers.
- Single treatments reduce severity significantly (up to 48%), with combined treatments yielding better results.
- Intense Pulsed Light (IPL):
- Improves pigment with relatively few side effects.
- Picosecond Lasers:
- Newer device showing promise, though overall results may lag behind QSND and AFL for most skin types.
- Q-switched Nd:YAG laser (QSND):
- Chemical Peels:
- Employ glycolic acid, salicylic acid, or trichloroacetic acid (TCA).
- Quickly exfoliate pigmented areas, but risk rebound pigmentation without proper maintenance.
- Microneedling and Microneedling Radiofrequency:
- Stimulates dermal repair and enhances delivery of active agents.
- Used as maintenance therapy to prolong results and reduce relapse.
- Platelet-Rich Plasma (PRP):
- Inhibits melanin synthesis through cell signaling.
- Studies show greater pigment reduction with PRP compared to tranexamic acid alone.

Key Points About Procedures
- Procedures should only be done by experienced dermatologists.
- Combination therapies (e.g., lasers plus topical agents) generally work better than isolated treatments.
- Risks are higher for darker skin types—start slow and monitor closely.
Oral and Systemic Therapies
For persistent or severe cases, oral medications can be safe and effective adjuncts.
- Oral Tranexamic Acid (oTA):
- Shown to reduce melasma severity effectively and safely based on multiple randomized trials.
- Often used in combination with topical agents for superior results.
- Low percentage (<18%) of side effects in clinical studies—primarily mild gastrointestinal symptoms.
- Polypodium Leucotomos (P. leucotomos):
- Plant-derived oral antioxidant supplement.
- Evidence supports its use as an adjunct to topical treatments and sunscreen for better control and prevention of relapse.
- Safe, with minimal reported side effects.
Physicians should thoroughly counsel patients regarding dosage, side effects, and long-term risks before starting oral therapy.
The Power of Combination Approaches
Recent studies confirm that combining modalities yields consistently better outcomes than single therapies. For example:
- Oral tranexamic acid combined with triple combination cream led to a 64% reduction in severity index after two months, with improvements maintained through microneedling radiofrequency.
- Device therapies such as fractional lasers, IPL, and microneedling are often paired with topical creams for enhanced effect and longer-lasting results.
- PRP injections combined with topical tranexamic acid outperform topical treatment alone.
Combination therapy also helps minimize the risk of relapse by targeting different pathways driving melasma pigment.
Prevention and Relapse Management
Melasma is prone to recurrence even after successful treatment. Dermatologists emphasize a proactive regimen:
- Daily sunscreen: Broad-spectrum SPF 30+ protects against both UVA and blue light, both leading triggers for melasma flares.
- Physical sun barriers: Hats, sunglasses, and shade.
- Avoid peak sun hours: Whenever possible, stay indoors between 10 AM–2 PM.
- Gentle skincare: Skip harsh scrubs, scents, and irritants that can spark pigmentation or inflammation.
- Lifelong maintenance: Continue topical agents like vitamin C and azelaic acid as ongoing brighteners.
- Regular dermatologist visits: Evaluate progress and monitor for side effects.
Relapse rates are high; studies show almost all patients experience recurrence if exposed to sun or stop protective routines. Continuous maintenance therapies, especially after procedures, help stabilize improvement.
Frequently Asked Questions
Q: Can melasma be permanently cured?
A: No known treatment cures melasma permanently. Most therapies control or reduce pigment and require ongoing maintenance.
Q: Is melasma dangerous?
A: Melasma is medically harmless but may cause emotional distress and lower self-esteem. Its primary concern is cosmetic.
Q: What is the safest treatment for sensitive skin?
A: Azelaic acid and short-term use of triple combination cream, under dermatologist guidance, are favored for sensitive skin types.
Q: How quickly will I see results?
A: Moderate improvement is often seen after 8–12 weeks of topical therapy; procedures may offer faster or more dramatic results, but require more monitoring.
Q: Are there any natural remedies for melasma?
A: Evidence for natural remedies is limited. Oral polypodium leucotomos shows promise as an adjunct but should not replace sunscreen and proven topical agents.
Final Takeaway
Melasma demands a tailored, persistent approach combining topical creams, targeted procedures, and systemic options. Adopting sun-safe habits and dermatologist supervision are vital to reduce flare-ups and maintain clearer skin long-term. While no solution offers a permanent cure, advances in combination therapies are yielding better, longer-lasting results for most patients.
