The GentleYAG PRO Effect
Patients will notice hair falling & reduction in hair count starting from 1st session.
Hair life cycle
Nd:YAG laser wavelengths has high absorption on melanin, when laser is absorbed, the energy thermally damages bulge & bulb cells, these cells are responsible for hair growth and removing them prevents future hair regrowth.
The hair is rich in melanin & has a life cycle of 3 stages:
- Anagen: this growing stage is the ideal target of laser hair removal, the hair is fully attached to the bulge & bulb cells which can be thermally damaged by burning the hair.
- Catagen & Telogen: hair in this stage stops growing and is not attached to the bulge & bulb cells. Hence burning hair by laser doesn't remove bulge & bulb cells, these cells can be removed once the hair cycle returns to anagen stage, which explains the need for multiple sessions.
Targeting melanin in hair
Hair removal lasers target melanin which is present in both hair & skin, hence a protection of skin from the thermal effect is needed. Laser technologies used in hair removal use different cooling technologies to cancel the thermal effect of laser & protect skin.
Candela's proprietary Dynamic Cooling Device (DCD) cools the skin precisely & consistently in a way that prevents under-cooling of skin that may cause burns, and over-cooling that may leak to hair itself & affect results.
Hair removal efficacy
Efficacy of hair removal necessitates using a pulse duration shorter than the Thermal Relaxation Time (TRT) of hair, when achieved, the hair gains temperature faster than losing it till it reaches the burning point.
The TRT of the hair depends on its size, smaller hairs have low TRT which needs low pulse duration to reach the burning point.
GentleYAG PRO avails 3 msec, the lowest pulse duration in hair removal supported by the high protection by the patent DCD cooling, which makes it effective in thick & resistant thin hair.
Oxyhemoglobin absorbs a portion of Nd:YAG laser energy, when laser is used with high enough energy, the vessels supplying the lesion with blood can be targeted and destroyed. Over few treatments the vascular lesion disappears, and the skin appearance improves.
GentleLaser provides an optional 1.5 & 3.0 mm hand piece that enables treating small vascular lesions & blue veins with accuracy & efficacy.

Numbers speak louder
More than 2,500 units sold in the region since launch realized by superior performance, effective results & patient demand.
GentleLaser allows combining biggest spot size, best pulse duration & highest repetition rate at any fluence. In other lasers, an increase in a particular parameter forces a decrease in other ones.
40 mins full body treatment
The 24 mm spot size & the high repetition rate covers more than 9 cm2 per second, this speed provides the shortest session duration among all competitors & enables treating more patients per day.
Efficacy enabled by safety
High skin protection enabled by the DCD allows the usage of '3 msec' ...the lowest hair removal pulse duration. This fast burning of the follicle doesn't allow it to cool down & therefore it enables effective hair removal even for thin hairs.
Hair reduction, not thinning
The fast burning of hair under '3 msec' fully damages the hair follicle stem cells. Longer pulse durations in other lasers partially damages hair follicle stem cells resulting in regrowth of fine hairs that are resistant to lasers.
Extra treatment speed
The DCD spray instantly evaporates & cools the skin. This allows the use of high repetition rate resulting in faster treatments hence more sessions per day. Other cooling types obligate using a lower repetition rate due to its gradual slow cooling rate.
The cold laser
The DCD cooling enables a comfortable & highly safe treatments that has become known by patients as "The Cold Laser".
Consistent automatic cooling
The DCD spray amount is set before starting the treatment & is equally sprayed with each pulse. Other cooling types are user dependent: slow movement may over cool the follicle & compromise results, whereas fast movement will lead to insufficient cooling of skin & burn risks.
The laser head in GentleLaser works up to a very high pulses count, when combined with its durability & long lifetime, it represents a safe investment with high returns.
It is possible to start with either Alexandrite or Nd:YAG alone and adding the other wavelength later. Expanding treatment portfolio is also available by adding optional 1.5 & 3 mm hand-piece for vascular treatments.
The detachable hand-piece tip design facilitates precise operation and minimizes human error by providing: a clear visibility of the treated area, simple shooting steps & a fixed perpendicular angle.
Matches small areas
GentleLaser comes with nine spot sizes from 6-24 mm, these several spot size choices facilitate matching the size of different areas like the bikini line & beard shaping with ease.
For all skin types
Nd:YAG is safe from skin types I-VI and can treat thick hair effectively. This allows covering a wider segment of patients from day one.
