Technology Behind the LightSheer Duet

Excellent clinical results begin with the LightSheer DUET 805 nm diode laser, which incorporates two advanced technologies:

Vacuum Assisted High-Speed Integrated Technology

• The large 22 × 35 mm spot size allows the use of low fluence.

• The unique pain-reduction mechanism ensures effective, fast, and comfortable treatments.

ChillTip Technology

• Integrated contact cooling protects the skin in treatment areas requiring precision and higher fluence.

How Vacuum-Assisted Technology Works:

• The vacuum gently draws the skin into the handpiece; the skin is stretched and thinned, bringing the target (hair follicle) closer to the energy source.

• Energy is delivered directly to the target, where melanocytes are separated and blood flow is reduced.

• The target is damaged, and the skin is released.

Advantages of Vacuum-Assisted High-Speed Technology:

• Efficiency: Reduction of competing chromophores allows more effective laser energy delivery.

• Safety: Less energy is absorbed by the epidermis, and lower fluence is sufficient because the target is closer to the energy source.

• Pain reduction: The unique vacuum mechanism activates touch and pressure receptors in the skin, inhibiting pain signal conduction.

How ChillTip Works:

• The skin is cooled before and during the treatment.

• The skin is compressed, then the laser beam is applied, damaging the target.

Advantages of ChillTip Technology:

• Safety: Excellent epidermal protection through contact cooling.

• Patient comfort: Continuous skin cooling significantly reduces pain and discomfort.

• Effectiveness: Compression moves the hair follicle closer to the surface, constricts blood vessels, and reduces competing chromophores. High fluence allows treatment of areas requiring precision and fine, light-colored hair.
