Laser hair removal devices are based on the principle of selective solar thermodynamics. By properly adjusting the laser's wavelength, energy, and pulse width, the laser can penetrate the skin and reach the roots of the hair follicles. The light energy is absorbed and converted into heat energy, which decomposes the regenerative capacity of the hair follicle tissue and causes hair to fall out without further damaging surrounding tissue. The use of modern diode laser technology can not only achieve the purpose of longer-term hair removal or delayed hair regeneration time, but also has extremely low side effects.
How Does it Work?
Diode lasers use a specific wavelength that is effectively absorbed by melanin (leaving other tissues unaffected). The light energy is then converted into heat, which is then conducted through the hair shaft to the dermal papilla (the point of hair growth). This heat damages the capillaries there, causing them to shrink and stop supplying nutrients to the hair follicles, achieving the desired effect.
Laser hair removal is suitable for all dark and light hair types, but is ineffective for white hair.
Diode laser hair removal technology can also be combined with a cooling system to reduce pain and enhance treatment comfort.
Modern diode hair removal machines typically combine 755nm, 808nm, and 1064nm wavelengths into a single system. Each wavelength has its own unique uses:
- 755nm: Ideal for fair skin and fine hair. Its high melanin absorption allows it to penetrate deep into the surface layers.
- 808nm: The most commonly used, suitable for all skin types. It offers a balance of depth, intensity, and safety.
- 1064nm: Ideal for darker skin tones due to its deeper penetration and lower melanin absorption.
These multi-wavelength systems offer a comprehensive solution, making them a popular choice for salons, clinics, and medical spas.
Optional 808nm Wavelength
Due to its precise and strong absorption of hair follicle melanin, deep tissue penetration and minimal damage to surrounding skin, it strikes a balance between efficacy and safety, making it a popular choice for hair removal treatment.

What is the course of treatment like?
Most areas require 6-8 treatments, while some areas require 3-5 to achieve effective results. Some individuals may require more or fewer treatments. Treatments are typically spaced 4-6 weeks apart to align with the hair growth cycle.
Regardless of the technique used, hair removal results will vary from person to person. The specific number of treatments and the effectiveness of the treatment will depend on factors such as hair color, skin tone, skin type, treatment area, and individual response.
Why can't hair removal be effective in one treatment?
This has to do with the nature of hair growth. Our hair goes through three phases:
-
The anagen phase:
During this phase, hair follicles are active, hair roots are well-nourished, melanin content is highest, and hair is most sensitive to the light from the hair removal device, making it the optimal time for treatment.
-
The catagen phase:
Hair follicles begin to shrink, hair growth stops, melanin levels decrease, and light absorption capacity decreases.
-
The telogen phase:
Hair follicles enter a "dormant" phase, and hair naturally falls out. At this stage, melanin is almost nonexistent, and the effectiveness of a hair removal device is limited.
In other words, at any given time, some hair on the skin is in the "insensitive" catagen or telogen phase. Therefore, a hair removal device requires multiple uses to cover all the hair's anagen phases, gradually devitalizing the hair follicles.
Diode Laser hair removal VS other hair removal methods
Diode Laser
&
IPL
Diode lasers and IPL are both technologies used for hair removal, but they differ in how they deliver light energy and how effectively they are used.
Diode lasers emit a single, focused wavelength, while IPLs emit a broad spectrum of multiple wavelengths. This difference in light delivery affects their targeting capabilities.
Diode lasers generally offer more precise and effective hair removal, particularly for those with fair skin and dark hair. However, IPL treatments are more cost-effective and better suited for certain skin and hair types.
Depilatory
creams
Depilatory creams work by dissolving hair with a chemical agent. They're simple to use, relatively painless, and suitable for large areas. However, they carry the risk of chemical irritation, a pungent odor, and can cause allergic reactions in some users, and their effectiveness is short-lived.
Razors
Razors are highly portable and inexpensive, but they only cut hair on the surface of the skin, leaving the follicles intact. Furthermore, shaving leaves the hair with a blunt, rounded cross-section, making the newly grown hair feel harder and appear thicker, which is the reason for the "shaving makes hair thicker" illusion.
Wax
While waxing removes the hair shaft and some of the root, it doesn't completely destroy the follicle. Furthermore, repeated pulling can irritate the follicles, causing them to grow further and more tangled, and even trigger folliculitis.
The core advantage of diode hair removal devices lies in their ability to address the root cause rather than the symptoms. They use technology to directly target the follicles, inhibiting hair regrowth at the root.

Applying chemicals to dissolve hair is simple and relatively painless, making it suitable for large areas of hair removal.
However, there is a risk of chemical irritation, allergic reactions, a pungent odor, and a short duration of 1-2 weeks. |
It's highly portable, easy to use, and inexpensive, allowing you to do it at home.
However, it only removes superficial hair, which can easily damage the skin. It can also stimulate hair follicles and accelerate hair growth, so the effects are short-lived. |
This method uses adhesive forces to pull hair out of the follicles, completely removing hair. It's suitable for small areas and can last 2-6 weeks.
However, it can be very irritating to the skin and can easily cause pain, redness, swelling, infection, and folliculitis. |
Is it safe?
Laser hair removal technology uses a selective wavelength. The laser targets the hair shaft, instantly heating it and destroying the hair follicles. The skin absorbs little or no laser energy, causing no damage to the skin itself and no impact on sweat gland function. Therefore, laser hair removal is safe.
(Note: It is crucial to select a qualified and experienced physician to ensure a safe and effective procedure.)
Preparations Before and After Surgery
Laser hair removal, as a safe and effective method, is increasingly popular. However, first-time users are inevitably curious about what precautions should be taken before and after the procedure. After all, every step of laser hair removal has clear operating procedures and precautions.
Preoperative preparation
- A professional physician will consult with you to understand your skin condition and determine if laser hair removal is suitable for you.
- You will then undergo a professional skin examination with your physician to develop a treatment plan tailored to you, including the type of laser, energy settings, and estimated number of treatments.
(Be sure to inform your physician of any recent sun exposure. Hair removal is not recommended within a week of sun exposure to avoid excessive heat damage to the skin.)
(If there is a wound, inflammation, or rash at the treatment area, wait until it has fully healed before proceeding with hair removal.)
Postoperative preparation
After laser hair removal, the skin is slightly sensitive and requires proper care to avoid adverse reactions and prepare for the next treatment.
- Immediate Care:
Immediately after the procedure, apply a cold compress to the hair removal area for 10-15 minutes to relieve any warming sensation and minor redness and swelling.
- Strict Sun Protection:
Post-treatment skin is more sensitive to UV rays. Apply SPF 30+ sunscreen and wear a hat and long-sleeved clothing when outdoors.
- Avoid Irritation:
Avoid using hot water on the hair removal area for 48 hours after the procedure. Avoid using shower gels, alcohol-based skincare products, or fragrances. Avoid using saunas, steam rooms, or other high-temperature activities.
- Moisturize:
Apply a mild moisturizing lotion to relieve dryness.
- Observe Recovery:
If you experience mild peeling or itching, avoid scratching. Apply a medical moisturizer for relief. If you experience significant redness, swelling, or blisters, contact your doctor immediately.
During the entire treatment, avoid plucking or waxing the hair to prevent it from affecting the absorption of laser light by the hair follicles. If the hair grows out, it can be gently shaved with a razor.

FAQ
Q: Is permanent hair removal real?
A: Laser hair removal is permanent. However, this isn't achieved in a single treatment. The laser slows hair growth, causing it to lighten with each treatment until it stops growing. The laser can't reach all hair strands at once, and given the natural growth cycle of hair, multiple treatments are required to achieve permanent hair removal. So, if you want to permanently remove unwanted body hair, laser hair removal is a good option.
