The Asian Problem of Frequent Laser Toning for Melasma

Area of Science:

• Dermatology
• Aesthetic Medicine
• Laser Therapy

Background:

• Laser toning and laser facials are increasingly popular treatments for melasma in Asia.
• Patients often undergo these procedures multiple times per week, sometimes daily, based on manufacturer recommendations.
• The trend of frequent laser treatments for melasma is growing.

Purpose of the Study:

• To investigate the outcomes of frequent laser toning for melasma treatment.
• To assess the potential side effects of undergoing laser facials multiple times a week.
• To evaluate the long-term effects of intensive laser therapy on melasma.

Main Methods:

• A study was conducted on 23 Chinese patients with melasma.
• Patients received laser treatments three times per week for two consecutive months.
• A follow-up period of four months with rest was implemented post-treatment.

Main Results:

• All 23 patients developed bilateral confetti-like hypopigmentation after two months of frequent laser treatments.
• Of the 13 patients available for follow-up after four months, none showed signs of repigmentation.
• The intensive laser treatment regimen resulted in persistent hypopigmentation.

Conclusions:

• Frequent laser facials or laser toning at regular intervals can lead to undesirable outcomes like hypopigmentation.
• The study suggests that such intensive treatment protocols should not be performed regularly.
• Alternative or modified treatment approaches may be necessary for melasma management with lasers.
