Clinical Endpoints • PFEs – Perifollicular erythema: The treatment area should appear red – Perifollicular edema: There should be swelling around each hair follicle • Some patients will experience a hive like response • Lighter hairs may not respond as significantly

Post-Treatment Instruction • After – Cool compresses can be used to reduce patient discomfort

Pigmented Lesions • Clinical Endpoint – You may hear a “Snap” while treating. – The darker the lesion, the louder the “Snap” – It is not uncommon to see a “Frosting” of the lesion Single Pulse Only!

Pigmented Lesions • Clinical Endpoint: – The lesion will darken within 5 - 10

Pigmented Lesions • Clinical Endpoint: – The lesion will darken within 5 - 10 minutes after treatment and may remain so until the lesions forms a micro-crust. Use of an ointment is recommended. Aquaphor, bacitracin or even vaseline can be used to keep area moist until the crust falls off. The skin underneath will be pink. There is a gradual return to normal skin color over time.
