Permanent Hair Removal: It is suitable for hair of all skin tones and has a good hair removal effect.

Safety: stable performance, long service life, and real-time control by intelligent microprocessor.

### 2.3 Potential risks

The most common complications of Intense pulsed light therapy device are postoperative local erythema and follicular edema, most of which resolve spontaneously within a few hours. complications are localized crusting, purpura, blisters, hyperpigmentation Rare or hypopigmentation, and increased sebum production. Adverse reactions after hair removal are mainly related to energy density and epidermal melanin content, and are also significantly related to seasonal changes, treatment sites, and solar radiation. Adhering to preoperative and postoperative guidance and correct operation can reduce adverse reactions.

### 2.4 Processing method

(The following processing steps and methods are for reference only, the actual parameters and operating procedures are subject to clinical use)

#### 2.4.1 Preoperative preparation

- 1) For patients with dark skin, sun radiation should be avoided as much as possible before surgery. It is best to use sunscreen for 4 to 6 weeks. For those with a tendency to pigmentation, hydroquinone can be added to prevent it.
- 2) The treated area must be skin-prepared prior to treatment, so hair, oil and dirt should be thoroughly shaved.

{11}------------------------------------------------

### 2.4.2 Anesthesia

Whether anesthesia is required during treatment should be determined according to the treatment site and size, whether it is a sensitive area, and the patient's pain. Generally, only topical anesthesia can be used.

### 2.5 Clinical considerations

- 1) Generally closely related to energy density, treatment outcome and inflammatory status after skin damage. High energy density is more effective, but at the same time, the inflammatory response is greater; the deep skin is also damaged. The energy is processed starting at low energy and gradually increasing the energy density until better results are achieved.
- 2) The maximum energy allowed is inversely proportional to the skin pigment. Generally, the skin is darker and has a lower energy density to reduce the absorption of more light energy into heat by the epidermis. A good cooling system is very important to the treatment, to protect the skin from burns to the greatest extent, and it is better for dark skin.
- 3) Shave excess hair before surgery, as excess hair absorbs energy and heats it on the epidermis, which may cause partial skin burns and damage the probe.
- 4) A good cooling system will reduce the temperature of the skin. Cold probes help to increase allowable energy density and partial anesthesia. Cooling is highly recommended throughout the treatment, especially for darker skin. Dark skin absorbs energy more easily than light skin.

### 2.6 Intense pulse light handle cleaning

When the treatment is complete, remove the handle, clean the top of the handle with a relatively soft cotton cloth and keep it dry.

- 1) Cleaning process
After processing is complete, exit the operating program and turn off the power of the device. Soak a soft cotton cloth in 75% alcohol and wipe the top of the handle clean until the alcohol has evaporated again. Then wipe the surface marks with the soft cotton cloth.

- 2) Warning message
Intense pulsed light processing precision optical components, please avoid falling and make them subject to blunt force impact or not allowed to open, otherwise the intense pulse light module will not emit light normally; This is a large impact of the intense pulse light output. The surface cleanliness of the optical crystal, therefore, before use Inspection and proper cleaning. The handle transfer system should avoid serious damage caused by bending during use.

### 2.7 Contraindications

## Chapter 6 Instructions for Use

### 6.1 General Instructions

The Intense pulsed light therapy device is an intense pulsed light system that provides intense pulsed light in the wavelength range of 650nm-1200nm. Intense pulsed light (IPL) therapy device employ the principle of selective thermal decomposition. That is, thermal damage to the target chromophore is achieved by using light of an appropriate wavelength in a pulse that exceeds the thermal relaxation time of the chromophore, but by limiting the pulse width below the thermal relaxation time of the skin. Thermal damage to the target chromophore is caused by using light of an appropriate wavelength, but preserving normal skin by limiting the pulse width to a pulse width below the skin's thermal relaxation time.

Intense pulsed light differ from lasers in that they provide multiple wavelengths in each light pulse, rather than just one. In general, IPL enhances penetration without using excessive energy levels and is able to target specific chromophores. Based on this, the Intense pulsed light therapy device is indicated for use in surgical and aesthetic applications in permanent hair removal.

{32}------------------------------------------------

a The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz. The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 - MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99 MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.

b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these frequency ranges.

C Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the IPL is used exceeds the applicable RF compliance level above, the IPL should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Intense pulsed light therapy device.

d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
