1. General clinical data (types of hair removal treatment area, total number of cases and selection of cases):

Subject: whole body hair removal(10 males and 10 females)

Test content: The hair removal treatment effect of S808k on patients with excessive hair.

Experimental purpose: to verify the hair removal treatment effect of the product through experiments.

Experimental parts: face, neck, body parts containing hair and other parts.

Treatment part in this case: 5

2.Things used in the treatment

S808K machine, camera, skin repair cream, 75% alcohol, repair factor,and mask shaver etc

3. Test method:

Before treatment, choose the skin type (type I-VI), and select the corresponding parameter, and frequency according to the condition of the hair. When doing the treatment for the first time, it is better to do it with lower energy in case of the skin is having red spots after the treatment.

Treatment Steps

1. Cleanse treatment area and take photos before treatment.

2. Choose treatment energy by the skin types and hair types.

3. Shave off the hair on the treatment area before. Both doctor and patient should be under good protection of the eyes(patient uses blinder and doctor wears protective glasses).

5. Treatment skills

1. Can treatment one fixed area by sliding the handle but not stay in one fixed area or it will case skin burning.

2. Dark skin should not use high energy while the skin can be burned.

3. If the hair is strong and black and it is suggested to go over less time and lower energy.

4. Fine hair with shallow color should use lower energy and longer pulse duration to heat up the hair follicle and destroy it.

6. Possible adverse events and side effects found in clinical trials during the treatment

1. Skin reddish and pimple is the normal skin reaction.

Solution: Apply cold compress or clod wind machine right after the treatment and stop till the skin reddish is gone

2. Blisters, hyperpigmentation are postoperative complications after the treatment.

Solution: External use of drugs to eliminate pigmentation (kojic acid cream),or to take (vitamin C, vitamin E, anti-allergic drugs, etc.)

7. Clinical trial effect analysis

1. When treating with higher energy and the treatment times is reduced as expected

2. If want to reduce the hair in a permanently manner and the treatment times should be at least 3-6 times depending on the treatment area

3. 808nm diode laser is not suitable for black skin tone

4. Fine hair needs more treatment times when compare with the long and black hair

5. Stronger hair follicle may fall out right after the treatment while the fine hair will fall off 7-15 days after the laser treatment.

8. Conclusion

1. Diode lasers use a single wavelength of light that has a high abruption rate in melanin. As the melanin heats up it destroys the root and blood flow to the follicle disabling the hair growth permanently.

2. When treatment the hair for at least three consecutive months and the hair can be permanently reduced
