Update on Melasma Treatments

Area of Science:

• Dermatology
• Aesthetic Medicine
• Skin Biology

Background:

• Melasma is a frequent facial hyperpigmentation disorder.
• It shares characteristics with photoaged skin, complicating treatment.
• Recurrence is common due to underlying photoaging features.

Purpose of the Study:

• To review conventional and innovative melasma treatments.
• To provide an overview of melasma pathogenesis.
• To highlight the need for comprehensive therapeutic strategies.

Main Methods:

• Literature review of existing studies on melasma.
• Analysis of therapeutic approaches including topical, systemic, chemical peeling, and laser therapies.
• Examination of melasma's pathological features and comparison with photoaging.

Main Results:

• Various treatments show efficacy but recurrence is high.
• Melasma exhibits dermal changes similar to photoaging, such as basement membrane disruption, solar elastosis, angiogenesis, and mast cell infiltration.
• A multi-faceted approach targeting both epidermal and dermal layers is suggested.

Conclusions:

• Melasma management requires addressing its complex pathogenesis, including photoaging components.
• Integrated treatment strategies are essential for improving long-term outcomes.
• Further research into innovative treatments is warranted.
