Treatment Options for Melasma

Introduction to Melasma Treatment

The American College of Dermatology recommends a combination of topical therapies, strict sun protection, and potentially advanced procedures like platelet-rich plasma (PRP) injections for optimal melasma outcomes 1

Sun protection is the foundation of any melasma treatment regimen and should include broad-spectrum sunscreen (SPF 30 or higher, preferably SPF 50+) that must be reapplied every 2-3 hours during outdoor exposure 1

Platelet-rich plasma (PRP) injections have shown significant improvement in melasma within 6 weeks as measured by modified Melasma Area and Severity Index (mMASI) scores 2, 3
PRP combined with oral tranexamic acid demonstrates higher efficacy (90.48%) compared to tranexamic acid alone (73.68%) with lower recurrence rates 2, 3

Four intradermal PRP treatment sessions administered every 2-3 weeks 2, 3
Follow-up evaluation one month after the last treatment 3
Maintenance treatments may be required every 6 months as melasma is a chronic condition 1

Additional sun protection measures should include wearing wide-brimmed hats, seeking shade during peak UV hours (10 am to 4 pm), and using UV-protective clothing 1

Begin with strict sun protection and first-line topical therapy, and if inadequate response after 8-12 weeks, consider adding or switching to PRP injections 1, 2, 3
For maintenance, continue sun protection, consider intermittent use of topical agents, and maintenance PRP treatments every 6 months 1, 3

Discontinuing treatment too early, as maintenance therapy is essential for melasma, a chronic condition with high recurrence rates 1

Intradermal PRP injections are more effective than intradermal tranexamic acid (TXA) for treating melasma, while oral TXA is more effective than topical TXA for hyperpigmentation disorders, as recommended by the American Academy of Dermatology 4, 5, 6

PRP intradermal injections have shown higher efficacy compared to intradermal TXA injections with similar side effect profiles, according to the American Society for Dermatologic Surgery 4, 5, 6

Intradermal platelet-rich plasma (PRP) injections are the most effective treatment for melasma, showing significantly better results than other therapies including tranexamic acid injections 7, 8
Intradermal PRP injections have demonstrated superior efficacy compared to intradermal tranexamic acid (TXA) injections with similar side effect profiles 7, 8
PRP treatment protocol consists of monthly intradermal microinjections (1 cm apart) for three to five treatment sessions 7
Studies measuring modified Melasma Area and Severity Index (mMASI) scores show that PRP intradermal injections result in a higher percentage of improvement compared to TXA injections 7, 8
Mean mMASI score reduction with PRP is significantly greater than with TXA (53.66% reduction with PRP-TXA combination vs. lower reduction with TXA alone) 8
Patient satisfaction is consistently higher with PRP treatment compared to other modalities 7, 8
