Diode laser hair removal is a gentle laser hair removal treatment method, which can protect the skin while removing hair. This laser hair removal method can be used in all skin and hair types and has significant effects. But do you really understand the treatment method of diode laser hair removal? Here are some common questions, I hope I can solve your doubts!
What is Laser Hair Removal？
Laser hair removal is a technology that uses laser energy of a specific wavelength to specifically destroy melanocytes in hair follicles, thereby achieving the effect of long-term reduction or permanent removal of body hair. The principle is that the laser can penetrate the skin surface directly into the deep of the hair follicles, and is absorbed by the melanin in the hair follicles and converted into heat energy, thereby destroying the structure of the hair follicles, making them lose their ability to grow, and achieving the purpose of hair removal. Currently, the commonly used hair removal laser instruments in clinical practice include semiconductor lasers, ruby lasers, long-pulse alexandrite lasers, Nd:YAG lasers, etc.
Is laser treatment for hair removal safe?
Laser hair removal technology is now relatively mature. Most people experience no adverse reactions during and after laser hair removal. For a few people, local redness after surgery is a temporary reaction. As long as the operation is performed in a regular medical institution and the doctor’s orders are strictly followed, the condition will recover.
Is diode laser hair removal effective?
Diode laser hair removal is an effective treatment method. Many patients find that their hair can be removed for a long time. There is
almost no discomfort during the process of diode laser hair removal.
Best laser for laser hair removal
In 2023 data, the best type of laser for laser hair removal is the alexandrite laser (755 nm), especially the 755 nm semiconductor laser produced by Foton in Israel. This wavelength of laser can be effectively absorbed by melanin, thereby destroying the hair follicles and achieving the effect of hair removal. It is suitable for lighter skin types, but extra care is needed when treating darker skin to avoid side effects such as folliculitis and pigmentation.
How many treatments are needed for laser hair removal?
The number of laser hair removal treatments that need to be arranged depends on the treatment area. In most cases, you can get significant results after 3-5 treatments. To achieve complete and permanent hair removal, 7-10 treatments may be required at different
times.
Does laser really remove hair permanently?
Laser hair removal can achieve the effect of permanent hair removal, but it generally requires 3-5 systematic treatments. Because hair growth goes through the growth phase, regression phase, and resting phase. Laser hair removal is 75% effective for hair in the growth phase, 25% effective for the regression phase, and almost ineffective for hair in the resting phase. Laser can only work after the hair enters the growth phase. Therefore, laser hair removal requires multiple times to achieve obvious results.
Because different parts of the body have different growth cycles, the interval between each treatment is also different. For example, the hair on the head and face has a relatively short resting period, so the interval can be as short as 1 month. The resting period of hair on the trunk and limbs is relatively long, so the treatment interval is preferably 1.5 months.
Is laser hair removal safe on the face?
Laser hair removal is extremely safe in the facial area. The laser pulses used for the face are much milder than those used for other thicker skin areas on the body. If you feel uncomfortable with the intensity of the laser at any time, you can adjust it immediately.
Can laser hair removal also remove scars?
Specialized medical lasers can be used to remove scars. However, every single surgery must use the correct type of laser and be set to the appropriate settings.
Advantages of laser hair removal
- 1.Root removal
During laser hair removal, black hair absorbs heat, and the heat diffuses to the surrounding tissues, which can “eliminate the entire hair follicle”, and the effect is generally long-lasting.
- 2.Precise and controllable
The process of laser hair removal is finely controllable. In normal operation, other skin tissues will not be damaged except for the hair follicles. The current laser technology uses the principle of extended selective photothermal action, which can accurately control the range of heat diffusion, only “burning” the hair follicles, and the surrounding skin tissue is not damaged, which is very safe.
- 3.High efficiency
The efficiency of laser hair removal is 90%. The treatment effect of hair in different parts, different thicknesses and colors is different, but even if it cannot be completely removed, the remaining hair will become thinner and softer, and the growth rate will slow down. According to clinical experience, after 3 times of “freezing point hair removal” treatment, most people can remove 90% of their armpit hair, 75% to 80% of their limbs and trunk hair, and 60% to 70% of their lip hair.
Does laser hair removal have side effects?
When laser hair removal is performed correctly, the risk of side effects is extremely low. Qualified practitioners must customize laser settings based on your skin color and treatment area.
In most cases, patients who receive laser hair removal on the face or neck will cool the skin with a cloth or cream shortly after treatment. There may be slight redness and swelling, but it should not develop into swelling. Cosmetics should not be used immediately after treatment.
How to choose the appropriate treatment?
① Since the hair follicles in different parts are located at different depths under the skin, the depth of penetration of light with different wavelengths into the skin is different. Broad-spectrum strong light can effectively damage the multipotent cells of the hair bulge and the hair bulb at different depths under the skin, and both are closely related to the growth of hair follicles. Damage to multipotent cells can permanently remove hair; ② The spot area is large and the treatment speed is fast; ③ The parameters can be adjusted flexibly, and the appropriate energy and filter can be selected according to the skin type. Multiple treatments are required.
- Long-pulse width emerald laser hair removal device
1.The wavelength is 755nm, which is also one of the most widely used laser hair removal devices in clinical practice. It has good clinical effects and fewer side effects. It weakens the specificity of melanocytes, but increases the penetration depth of the laser, which is absorbed by melanin and reaches the hair follicles, improving the efficacy.
- A major advantage of this device is that the large spot of 18mm can easily and quickly complete the hair removal treatment. Suitable for all people, especially for Caucasians and blacks, such as those with white skin and light hair, or those with dark skin and dark hair.
- Freezing point hair removal
It also uses the selectivity of light, relying on semiconductor laser technology to emit lasers to penetrate the surface of the skin and be absorbed by the hair follicles to achieve the purpose of completely destroying the hair follicles, and finally achieve hair removal. However, freezing point hair removal is not suitable for everyone. People with darker skin may have the risk of white spots after treatment.
Who is not suitable for laser hair removal?
1.Minors under the age of 18 and pregnant women are prohibited from laser hair removal;
2.Skin that is prone to tanning, skin that has been exposed to the sun recently or has already tanned is best not to undergo laser hair removal;
3.People with open wounds (such as knife wounds), scar hyperplasia or other skin disease history;
4.Patients who have recently used photosensitive drugs and have photosensitivity reactions;
5.Patients with diabetes and epilepsy, bleeding tendency, malignant tumors, and herpes simplex;
Precautions before laser hair removal
Avoid sun exposure before laser hair removal. Do not shave your hair without authorization before the first treatment so that the doctor can evaluate the efficacy and develop a treatment plan. Do not pluck hair 6 weeks before laser hair removal, and do not use products such as wax and depilatory cream, otherwise it will seriously affect the effect of laser hair removal.
One day before laser hair removal, you can use soap to clean the hair removal area. Be careful to avoid using shower gel as much as possible, because some shower gel will adhere to the surface of the skin and react with the gel needed during the treatment, affecting the efficacy and may increase side effects.
If the doctor requires hair removal, it can be shaved with a razor. People who are pregnant, have scar constitutions, or are taking certain medications orally should inform the doctor of the situation and the medications they are taking so that the doctor can determine whether they are suitable for laser hair removal.
Precautions after laser hair removal
♥Try to reduce sun exposure within six months after laser hair removal. It is recommended to use sunscreen with SPF greater than 50.
♥After treatment, the hair removal area may experience slight redness and swelling, skin sensitivity, and hot or itchy sensations. If you feel pain, use ice to relieve the pain.
♥Do not use detergent, hot water, or scrub hard within one week after hair removal.
