Effective Treatment for Melasma
The most effective approach to treating melasma combines triple combination cream (hydroquinone, tretinoin, and corticosteroid) with strict sun protection, with platelet-rich plasma (PRP) injections as a highly effective second-line option for resistant cases. 1, 2
First-Line Treatment Strategy
- Begin with strict sun protection as the foundation of any melasma treatment regimen, including broad-spectrum sunscreen (SPF 50+) reapplied every 2-3 hours during outdoor exposure 2
- Use FDA-approved 4% hydroquinone cream as the primary topical treatment for gradual bleaching of hyperpigmented skin conditions like melasma 3
- Consider triple combination cream (hydroquinone, tretinoin, and corticosteroid) as the most effective topical treatment option for melasma 4
- Implement additional sun protection measures including wide-brimmed hats, seeking shade during peak UV hours (10 am to 4 pm), and using UV-protective clothing 2
Second-Line and Advanced Treatment Options
- For cases resistant to first-line therapy after 8-12 weeks, consider platelet-rich plasma (PRP) injections which have shown significant improvement in melasma within 6 weeks 1
- PRP treatment protocol consists of four intradermal sessions administered every 2-3 weeks with follow-up evaluation one month after the last treatment 1
- Radiofrequency microneedling is another effective option, with three treatment sessions spaced at least 21 days apart 2
- Oral tranexamic acid can be considered for moderate to severe recurrent melasma, especially when combined with PRP (90.48% efficacy compared to 73.68% with tranexamic acid alone) 1, 4
Treatment Algorithm
Initial Phase (0-8 weeks):
Second Phase (if inadequate response):
Maintenance Phase:
Important Considerations and Precautions
- Test for skin sensitivity before using hydroquinone by applying a small amount to an unbroken patch of skin and checking within 24 hours 3
- Hydroquinone should not be used where there is itching, vesicle formation, or excessive inflammatory response 3
- Patients should be counseled that melasma is a chronic condition requiring long-term management and maintenance therapy 2
- Avoid damaging habits such as smoking that may worsen melasma 2
- Hydroquinone should be used with caution in pregnant women (Category C) and nursing mothers 3
Alternative Treatment Options
- 20% azelaic acid cream has shown to be more effective than 4% hydroquinone in some studies for mild melasma after 2 months of treatment 5
- Liposomal tranexamic acid 5% has demonstrated comparable efficacy to 4% hydroquinone with fewer side effects 6
- Chemical peels and laser treatments may be considered but have mixed results and higher risk of adverse effects compared to topical treatments 4, 7
Common Pitfalls to Avoid
- Discontinuing treatment too early - melasma is a chronic condition with high recurrence rates requiring maintenance therapy 1
- Inadequate sun protection - even minimal sunlight exposure can sustain melanocytic activity and cause repigmentation 3
- Forgetting to reapply sunscreen after swimming, sweating, or after 2-3 hours of continuous exposure 2
- Using photosensitizing medications concurrently with melasma treatment 3
