8.7 Treatment Recommendations
1. Follow Device Start-Up Procedure from System Operation section.
2. Ensure that skin is clean.
3. Apply thin to thick layer of water-based gel to the treated area, mostly face.
Prior to using water-based gel, ensure that the container of ultrasound gel
has not passed the expiration date.
4. Basic treatment considerations:
– Treatment target is mainly face, or body, but not leg veins.
– Treatment targets are epidermal and junctional pigments, but not
dermal nevi and blood vessels 1-2mm deep and <0.5mm diameter (red
and purple), but not deeper and larger (blue and black).
– Set treatment parameters. Reduce ~20% fluence on thin sensitive skin
like neck or bony area like forehead. Further reduce fluence on thin
sensitive skin over bone like chest and hand dorsum and on off-face,
body areas, as well as on off-face areas, such as arms and legs.
– Use higher Fluence settings for vascular lesions than for pigmented
lesions.
– Use higher Fluence settings for lighter pigments than for darker.
– Use higher Fluence settings for larger and deeper veins than for
smaller and superficial ones.
– The Strong Cooling should protect the skin surface.
– Normal Cooling may be used after testing on very superficial and small
capillaries on light skin to avoid vessel constriction.
– Use a short pulse width for pigments on skin types I-II, occasionally III.
Can also start in Long Pulse then make additional pass in Short Pulse.
– Use a long pulse to prevent purpura or bruising in dense vascular areas
such as cheeks and chin.
– Do not treat moles or suspicious lesions. If unsure, consult a
dermatologist or do not treat.
– Treatment of facial melasma is controversial as it is a condition
controlled by hormones and may often reoccur. Furthermore, the
response is unpredictable, presenting no response, lesion lightening,
or even lesion darkening.
– In hair-bearing area there is a risk of hair loss, temporary or
permanent.
