Although autumn and winter are the best seasons for laser hair removal, many people choose laser hair removal before summer arrives, and it has become a popular beauty project.

Below, Litonlaser has sorted out the medical and aesthetic knowledge of laser hair removal to review and review the technology of laser hair removal, a hot beauty project!

Freezing point hair removal is currently the most advanced permanent laser hair removal method. Based on the principle of selective photothermal action, it uses freezing point diode laser hair removal equipment. The laser penetrates the surface of the skin to keep the hair follicles at a certain temperature, gently inactivates the hair follicles and surrounding stem cells, and achieves the purpose of permanent hair removal. It can remove excess hair on a large area without pain and coolness, effectively protect the surrounding skin, and achieve the purpose of rapid hair removal.

1. Principles of Ice-Point Diode Laser Hair Removal.
1.1 Principle of Laser Hair Removal.
Similar to the treatment of pigment spots and blood vessels, laser hair removal is also based on the principle of selective photothermal action. When the laser penetrates deep into the dermis, the melanin in the hair follicles and hair shafts will selectively absorb the laser, thereby generating heat.

However, unlike the treatment of pigment spots and blood vessels, the pulse width of the laser used for hair removal is wider than the thermal relaxation time of melanin, because our target tissue is not melanin. Current research believes that the vascular nerves in the hair papilla during the growth period, the hair matrix cells with strong differentiation ability in the hair bulb (called matrix above the hair papilla), and the hair follicle stem cells in the bulge of the hair follicle are the three important target tissues for permanent hair removal. The thermal relaxation time of the hair follicle is 40-100ms. The heat energy diffused from the melanin is transmitted from the hair shaft to the stem cells of the outer sheath of the hair bulb, destroying the germinal layer of the hair follicle, thereby achieving the purpose of accurately destroying the hair follicle structure.

1.2 Principle of Ice-Point Hair Removal.
Ice-point laser hair removal uses the gold standard 808/810 nm semiconductor laser for laser hair removal. Through a specially designed dual-pulse laser, it irradiates the skin with only a low energy density. The first laser pulse through the epidermis heats the skin tissue and hair follicles. The second pulse selectively raises the temperature of the hair follicles to about 45 degrees. The sliding 10Hz laser ensures that the hair follicles maintain this temperature for a period of time, and the hair follicles and growth stem cells lose their growth activity, thus achieving permanent hair removal.

The biggest difference between ice-point hair removal and traditional laser hair removal in mechanism is that traditional laser hair removal requires instantaneous high energy to burn the hair follicles, while ice-point hair removal gently inactivates the hair follicles automatically, so it can achieve the purpose of permanent hair removal without over-stimulating the skin to avoid pain or risks.

2. Energy setting and operation points of diode laser hair removal.
Diode laser is one of the most commonly used hair removal devices, with a wavelength of 800-810nm. The most famous “moonlight hair removal” and “freezing point hair removal” are semiconductor lasers. The 810nm band is traditionally deeper, and the melanin absorption is moderate, which is more friendly to people with dark skin.

The commonly used “freezing point hair removal” is mostly sliding. Due to the heat conduction of cold gel and the cooling of sapphire in the handle, customers usually feel better.

In terms of parameter setting, there will be east mode and professional mode, which can be selected according to needs. Usually the energy density is 10-13J/cm². Single-site operation should not be done according to the operation interface. It can be operated for about 30-40s, otherwise the risk of burns is relatively high. The diode hair removal machine is suitable for hair removal of large parts such as chest, back, limbs, etc., and it is more comfortable.

Operation skills: The treatment handle is held vertically and close to the skin and a certain amount of force is applied. Diode hair removal is generally used for large areas. The local area (upper arm/calf/thigh) can be divided into three areas. During treatment, the gel needs to be added and replaced to dissipate heat. During treatment, slide quickly without pausing, and slide faster in areas with thinner skin.

3. Three major advantages of freezing point hair removal.
3.1 Really painless.
No need to burn hair with high energy instantly, only warm feeling, no pain, with full white sapphire/sapphire cooling, hair removal is as comfortable as warm stone massage.

3.2 Really fast.
Adopting professional In-motion sliding technology, bid farewell to traditional dotting operation, with a repetition frequency of up to 10Hz, the hair removal speed is increased by 5 times.

3.3 Really safe.
Adopting 10J low energy density, 20ms long pulse width, and full cooling system, the probability of side effects is almost reduced to zero.

4. Precautions for freezing point hair removal.
Shave the hair in the treatment area;
Apply the glue on the skin;
Stick the light-guiding crystal to the skin surface for operation;
First make three test spots, and then observe the immediate reaction of the skin. The normal reaction is that the skin or the hair roots are slightly red, and sometimes there is a burnt smell;
When the energy density needs to be adjusted, the increase should not exceed 2J each time;
For people with darker and more sensitive skin, it is common for the skin to have a delayed reaction within 24-48 hours. The energy density should not be increased arbitrarily because the immediate reaction is not obvious;
Post-freezing point hair removal care: cold compress (not ice compress, not less than 4℃) for ten minutes to half an hour until the discomfort is relieved; try to avoid sun exposure; if there is no side effect on the skin, makeup can be applied.
5. Specific steps of diode laser freezing point hair removal.
Step 1: Skin preparation. The technical term is skin preparation, and in layman’s terms, it is called shaving, that is, use a disposable hair removal knife to shave all the hair on the surface of both arms so that the light waves can “pull out the hair roots” during hair removal. Before skin preparation, please keep the hair removal area clean to ensure the effect.

Step 2: Cold gel. Apply a gel with cooling and refreshing effects to the hair removal area to maximize the protection of the skin and minimize the discomfort during the hair removal process. Make sure there is no hair on the inside of the arm, and you can also evenly apply an appropriate amount of gel. When hair removal, it will be “closely contacted” by the light waves to achieve the effect of tightening the skin.

Step 3: Freezing point hair removal. Repeatedly contact the hair removal area with uniform force, allowing the light waves to thoroughly “encircle and suppress” the hair roots. As the intensity of the light increases, the skin will feel more and more intense. Different light waves are used, and the area of ​​hair removal and pain are different each time: the area of ​​freezing point hair removal is larger and there is no pain.

Step 4: Cleaning. Gently scrape off the gel and wash with clean water. After washing, quickly moisturize the skin and apply sunscreen. Do not use soap or other alkaline cleaning products to take a bath one week after hair removal.

6. Treatment of adverse reactions after diode laser hair removal.
6.1 Pain.
Pain during laser hair removal is a normal reaction. Thick hair shafts, dark skin color, and skin spots will cause additional pain. Current hair removal equipment has cooling devices to minimize pain. So we should try to remove the hair as cleanly as possible during pretreatment, leaving only the stubble at the root, and try to avoid spots and trauma. The gel can be applied a little thicker during diode hair removal, and avoid repeated sliding on the same part.

6.2 Erythema, edema around the hair follicles and other reactions.
This is a normal treatment reaction, and it can even be said to be the endpoint reaction of effective parameters. The degree and duration of erythema and edema are proportional to the treatment energy and treatment time, and are inevitably related to the customer’s skin color.
Usually erythema and edema around the hair follicles can subside on their own after a period of time. We strengthen cooling during the operation, apply cold compresses immediately after surgery, and use topical glucocorticoid cream or ointment when necessary. At the same time, inform customers of possible erythema and follicular edema. Due to different customer requirements, many customers do not expect adverse reactions after hair removal. While communicating, we can appropriately reduce the energy and number of repetitions according to customer requirements.

6.3 Other serious complications.
Diode laser hair removal is generally very safe. Occasionally, there are serious complications such as burns and pigmentation, which require us to control the parameters and endpoint reactions of the machine. For hair removal, it is not a one-time project, and there is no need to blindly increase the energy. Occasionally, there are reports that patients induce hair growth after laser hair removal. Personally, I guess that it is similar to the principle of hair laser treatment. Too low energy promotes local blood flow and metabolism of hair, thereby promoting hair growth. In this case, you can try to increase the energy and the number of treatments.

7. FAQ about diode laser freezing point hair removal.
Q: What is the wavelength of diode laser freezing point hair removal?
A: The wavelength of freezing point hair removal is 808 nm or 810 nm.

Q: Is freezing point hair removal permanent hair removal?
A: Yes, after 3 to 5 freezing point hair removal treatments, the hair follicles will be damaged and new hair will not grow for a long time, tending to permanent hair removal.

Q: Is ice therapy hair removal safe?
A: Very safe. Ice therapy hair removal is also called freezing point hair removal. It is a very safe laser hair removal method. Through the cold gel and the sapphire cooling system of the machine handle, the hair removal process can be made very safe and comfortable.

Q: Why do some people have more hair after laser hair removal?
A: If you find that your hair grows more after laser hair removal, it is an adverse reaction to diode laser hair removal. In the study of the hair life cycle, we found that low energy can promote hair growth. So in this case, you can increase the energy appropriately and use high energy to destroy the hair follicles to achieve hair removal.

Q: In hair removal, is cold laser better or hot laser better?
A: Laser hair removal is through the photothermal effect. The hot laser heats the hair at the hair follicle to inactivate the hair follicle cells, thereby achieving the purpose of hair removal, while the cold laser uses the treatment system on the machine, such as sapphire or white sapphire, to cool the surface of the human skin, and with cold gel, the customer’s epidermis feels cool and will not burn the skin. Therefore, the hot laser heats the skin follicles to remove hair, and the cold laser cools the surface of the human skin to ensure safety and suitability.
