Technology Behind LightSheer Duet

Excellent clinical results are achieved with the LightSheer Duet 805 nm diode laser, which uses two advanced technologies:

Vacuum Assisted High-Speed Integrated Technology

• The large 22 × 35 mm spot allows for low fluence treatments.

• The unique vacuum-assisted mechanism reduces pain, making treatments effective, fast, and comfortable.

ChillTip Technology

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

How Vacuum-Assisted Technology Works:

• The vacuum gently pulls the skin into the handpiece, stretching and thinning it, while drawing the target (hair follicle) closer to the energy source.

• Energy is delivered precisely to the target, melanocytes are separated, and blood flow is restricted.

• The target follicle is destroyed while the skin is released.

Advantages of Vacuum-Assisted Technology:

• Effectiveness: Reduces competing chromophores for more efficient laser energy delivery.

• Safety: Less energy is absorbed by the epidermis; lower fluence is sufficient as the target is closer to the source.

• Pain Reduction: The unique vacuum mechanism stimulates touch and pressure receptors, inhibiting pain signal transmission.

How ChillTip Works:

• The skin is cooled before and during treatment.

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

Advantages of ChillTip Technology:

• Safety: Excellent epidermal protection through contact cooling.

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

• Effectiveness: Skin compression moves the follicle closer to the surface, constricts blood vessels, and reduces competing chromophores. High fluence allows precise treatment of thin, light-colored hair.
