• Effectively destroys melanosomes and tattoo pigments
• Ultra-short pulse widths required to shatter melanosome/ pigments by photoacoustic effect

Benign Pigmented Lesions
• Discoloration caused by high concentration of melanocytes in a particular area
• Treatments include cover up with makeup, or painful removal by dermabrasion or cryosurgery
• Mostly for pediatric treatments or as an adjunct procedure in skin rejuvenation for adults
• Lasers remove pigmented lesions through photoaccoustic effects
• Melanin absorbs laser energy more intensely than the surrounding tissue which leads to fracturing of the pigment and melanocyte cell death
• Fractured melanin/melanocyte is removed by the immune system

Nevus of Ota
• First described in 1861• Bluish hyperpigmentation along the first or
second branches of trigeminal nerve• Most patients have no family history• Age of onset- perinatal period or puberty• Significant predominance among women
• Male to female ratio 1:4.8
• Female hormones suggested as potent stimuli
• Other stimuli include infection, trauma, or ultraviolet light exposure

Nevus of Ito, Mongolian spots & Other conditions
Nevus of Ito • Variant of Nevus of Ota. • Skin pigmentation occurs is more diffuse and
less mottled in the acromioclavicular region
Mongolian spot • Sacrococcygeal region • Usually regresses and disappears during
childhood. • The spot is found in almost all newborn Chinese,
Japanese and Mongolian children, as well as some white and black children.
