• Rhesa May at al.,

• Postpeel results

• Imidiate results excellent

• 3rd-6th week PIH (universal, all patients)

• GA peeling beweekly

• Bleaching regimen

• 6th month MASI score significantly decreased

• Conclusion: Perform just for refractory melasma patients

Non-abalative Fractional treatment has signficant improvement effect on the melasma pecthes Melanocyte count is decresed

But at 6th month follow-up, recurrence was noted in 50% patients

Non-Ablative: Remove melanin in dermal melanophages

Coclusion

In the management of melasma with ablative lasers is controversial

Thullium laser seems to promissing laser type for epidermal melasma

Needs further investigation

Topical bleaching agents remain the gold standart treatment

Combining pre&post laser and topical treatment greater efficacy

compared to treatments alone

Melasma; My Treatment Approach

Topical Treatment

Kligman formulation or TTT

Dermamelan peeling system

Sunscreen SPF 30+ or opaque

Oral Medication

Tranexamic acid 1500 mg/day PO

NAC 400 mg/day PO

Mesotherapy

Tranexamic acid + NAC +Vit-C equal, 0.01 ml/ cm2 weekly intervals

Laser

FPDL 585 nm, 7 mm spot, 2-2.5 J/cm2

Q-SW Nd-YAG 1064 nm, 6 mm spot, 0.6-1 J/cm2

Dermamelan Peeling
