The gold standard treatment Kligman's formulation, which contains hydroquinone, tretinoin, and dexamethasone, but its long-term use limited by the risk of exogenous ochronosis.

Facial hyperpigmentation, including melasma and post-inflammatory poses a significant dermatological psychosocial challenge. These conditions arise from complex interplay of genetic factors, hormonal influences, environmental exposures (UV, VL, IR), with management particularly challenging in skin color. This narrative review synthesizes current insights into the pathophysiology hyperpigmentation—emphasizing roles MC1R, tyrosinase, related enzymes melanogenesis—and evaluates both established emerging treatment modalities. A systematic literature search up to February 2025 identified studies addressing topical, oral, laser, combination therapies. Topical treatments, such as 5% alpha-arbutin 2% kojic acid cream, demonstrated efficacy comparable triple formulations but lower recurrence (p = 0.004). Low-dose tranexamic acid, delivered orally or via mesotherapy, significantly reduced modified Melasma Area Severity Index (mMASI) scores 0.02) improved quality life 0.03). Laser therapies—including picosecond Nd:YAG 755-nm lasers—produced mMASI reductions < 0.001), nonablative 1,927-nm fractional laser achieving 43% improvement pigmentation among darker types 0.0001). Adjunctive procedures, glycolic peels, supramolecular salicylic niacinamide, microneedling, further enhanced clinical outcomes 0.05–p 0.001). Preliminary evidence also supports acupuncture promising complementary approach. In summary, an individualized, multimodal strategy is essential for optimal facial hyperpigmentation. Further controlled are warranted refine these protocols enhance long-term therapeutic efficacy.

Abstract Melasma is a chronic, relapsing hyperpigmentation disorder that primarily affects photoexposed areas, occurring most frequently in adult women with darker skin phototypes. The primary factors contributing to its development include sun exposure, sex hormones (e.g., pregnancy), and genetic predisposition. highly prevalent Latin America, where many countries lie intertropical zones exhibit significant ethnic diversity because of centuries intermixing among Native Americans, Europeans, Sub‐Saharan Africans. Nine American experts formulated DELPHI‐based consensus develop valuable approach for treating melasma this diverse population. After establishing an accurate diagnosis, assessing the impact on quality life, determining disease severity, recommends mitigating known triggers promoting rigorous photoprotection. Active therapy should be tailored based individual characteristics pregnancy status, previous treatments, sensitivity). Treatment options topical depigmenting agents, systemic therapies, procedural interventions such as laser therapy, microneedling, chemical peels. Periodic reassessment treatment essential, strategies adjusted if targeted outcomes are not achieved. Once clinical remission attained, patients continue using agents maintain strict photoprotection measures prevent recurrence.
