4) Skin color is very important. For white to light color, you can adjust the laser power up to
80~100% for a higher performance, and the energy can be adjusted to 40~90J/cm2. For light
color to light brown, you need a lower laser power (30%~60% for example), with a longer pulse
width to protect any skin burning. Also you need to extend the treatment time for the dark skin
to inject enough energy to the skin and follicles.
5) The skin must be shaved before treatment.
6) The handle piece is better to be operated at SCANNING mode. It is faster for treatment.
7) Skin contact gel is no necessary for treatment. It won’t make the treatment better or improve
the skin feeling.
8) You need to wait for several minutes before the cooling tip becomes cold.

After surgery blisters and ulcers generated in the skin ,can be cured by antibiotic ointment and burn
cream (such as: Silverol or Biafine, etc.). Also low concentrations of steroid cream can be used to reduce
swelling.
If the blisters scab, should use vaseline or other moisturizing cream to keep it soft. Within 24 hours, do
not use any cosmetics, one month to avoid too much sun and strong exercise, adjust the diet, go out to
wear sunscreen;
9, 808 nm laser hair removal usually takes 4-6 treatments, each treatment interval of generally 1-1.5
months.
10, usually three times after treatment, and can be reached significant treatment effects.
7.4. Pre-treatment
7.4.1, Inquiry
Newly diagnosed patients, the attending physician should (or other qualified medical personnel) :
1),Excluding patients in recently 3-4 weeks with dark brown skin ,which caused by daylight or artificial
light tan.
2), 3-4 weeks will be excluded from sunlight or artificial light tan dark brown skin of patients.

3), asked in detail about the patient's medical history, including received what forms of treatment
previously to determine whether he / she is suitable to accept the 808nm laser hair removal treatment.
4), find out why patients seek treatment and his / her expectations.
5) discuss the 808nm laser hair removed treatment plan with the patient.
7.4.2 explanation
Newly diagnosed, the attending physician should tell the patient the following(or other qualified medical
personnel):
• treatment, there may be some discomfort / pain;
• After treatment, there may be temporary swelling / edema occur;
• To achieve the desired therapeutic effect may require several treatment, usually 4-6 times. Efficacy of
the treatment need to follow the gradual expression and the patient's actual expectation;
• There have temporary hyperpigmentation and skin texture changes and other minor side effects risk.
7.4.3 eye protection
When using 808nm diode laser hair removal machine, all persons in the treatment room (including
patients and all health care workers) must wear protective glasses to protect the retina. When the intense
pulsed light is used near the eye,doctors should give the patient over their eyes. Of course, the best
protective measures is to let the patient closed his eyes before the laser pulse launching after the system
ready to issue a "beep" sound,.
7.4.4, photo
Photographic archive for the patient before and after surgery (the patient face left, right and front).
Because many patients are unable to objectively evaluate treatment progress, these photos can be used
as evidence.
Patient photography should be used in the same environment similar to the speed, flash index and the
focal length, so the photos can do different time objective comparison.
7.5 Treatment
1) • allow patients to wear protective glasses sitting in the chair. Operators also wear safety glasses, and
remind the patient do not open their eyes during surgery.Operator select the best operating position
between the patients’ face and touch control panel.
2) • General from inconspicuous parts of the face, such as the front of the ear begin treatment. In the
treated area coated with 1-2mm cold gel, which will help cool the skin under the laser pulse and increase
the penetration of light pulses on the skin. Pulse emission in the cold gel, each light pulse treatment to
receive the site should be coated with a new cooling gel.
3) • placed in the treatment of head and perpendicular to the cold 1-2mm thick gel, the optical crystal
contacts in the skin, rather than the cold gel
4) • When the system issued a "tick" and ready sound. Pressing the trigger switch, a laser pulse.
5) (Selection of parameter is a very important aspect in clinical training, We recommend doctors firstly

beginning with 808nm laser hair removal machine to do the treatment of intense pulsed rejuvenation
should be very careful to carry out parameters. If you encounter more difficult cases, clinical experts
should be consulted.)
6) • in the course of treatment, when patients need referral for additional treatment, can appropriately
increase the energy density to obtain better results according to requirement. However, before the start
of treatment still need to launch the test spot to observe.
7) • After the treatment does not need any post-operative care. Patients can immediately put to work or
lives. Only parts of the general treatment of sun treatment, proper skin care can improve the strong pulse
of the relevant chromophore formation, pore size reduction and mitigation of color and light Shen aging
effect.
8) • After treatment, the color Shen and brown spots will be to deepen the color, it will reduce and
disappear after a few days.
