If you are an experienced expert in the beauty industry or run a beauty-related business, you are likely very familiar with laser hair removal. However, if you are a newly opened beauty salon owner or a customer looking for laser hair removal but have never tried it before, you may know very little about using laser hair removal devices. That's okay. I have over ten years of experience in the beauty equipment industry, and this article aims to help more people understand the core principles, usage steps, effects, and treatment courses of diode laser hair removal devices.
Why can 808nm diode laser devices effectively remove hair?
The principle behind 808nm diode laser hair removal is based on selective photothermolysis. The 808nm laser penetrates the skin to reach the hair follicle root. After being absorbed by melanin, the light energy is converted into heat, which is concentrated in the hair follicle, raising its temperature to a level sufficient to denature the proteins essential for hair growth. Lacking the necessary protein nutrients, the hair follicle cannot continue to grow, thus achieving permanent hair reduction.
Selective photothermolysis:
The 808nm wavelength of laser light is the optimal wavelength for targeting melanin in the hair follicle. It is more easily absorbed by melanin than by the surrounding skin tissue, thus minimizing severe thermal damage to the surrounding skin.
Complete laser hair removal steps
Many beginners don't know how to use the device correctly after receiving it. Below are the usage steps and experiences we summarized after using Newangie's advanced ice laser hair removal device. The usage steps of many brands of hair removal devices are actually quite similar, and we hope this will be helpful to you.
Equipment preparation:
- Add Water
Using the device without water may damage the handle. Therefore, before using the 808nm diode hair removal device, first fill the device with water, ensuring water is added to the water tank through the overflow port until water flows out.
- Turn on and Cool Down
Newangie's 808nm diode hair removal devices are equipped with a dual cooling system. Before use, turn on the machine and allow the handle to cool down for 2-3 minutes to prevent damage to the machine or skin injury from excessive heat during treatment. Once the crystals on the handle have frozen or feel cool to the touch, and you hear the water circulating, the device is ready.
Skin preparation:
- Shaving:
Because 808nm wavelength lasers have excellent absorption of melanin, to prevent hair from absorbing too much energy and burning the skin, we should gently shave the hair on the treatment area with a razor before the actual hair removal. This allows the laser energy to better penetrate the epidermis and act on the hair follicle root, while also avoiding discomfort.
- Cleansing:
Before starting the treatment, please wipe the skin with lukewarm water to ensure it is clean and dry, avoiding unnecessary infection.
Treatment process:
- Setting Parameters:
After turning on the machine, select appropriate parameters based on the patient's skin type, skin tone, and the area to be treated. When using Newangie hair removal devices, they provide an instruction manual with suggested parameters for different skin tones, skin types, and treatment areas, saving us a lot of trouble.
- Starting Use:
Hold the handle vertically against the skin and move it over the treatment area in a "dotting" motion, ensuring complete coverage. Each contact will emit laser pulses to the treatment area, and you will feel a cool and comfortable sensation when the handle contacts the skin.

How to care for your skin after diode laser hair removal?
Immediate Care:
- Apply cold compresses:
Apply ice packs to the treated area to reduce swelling and discomfort.
- Keep clean:
Gently clean the area with lukewarm water, avoiding harsh soaps or vigorous scrubbing.
- Avoid high temperatures:
For two days after hair removal, the skin is in a sensitive and stressed state, making it more prone to burns and irritation. Avoid swimming, saunas, and hot baths during this time to prevent exacerbating redness and swelling.
Short-Term Care:
- Sun protection:
The treated skin is more fragile. Prolonged exposure to ultraviolet rays can lead to hyperpigmentation, so sun protection is essential. When going out, apply high SPF sunscreen and wear a hat, mask, and sun-protective clothing for physical sun protection.
- Avoid irritation:
Do not pluck hair or use wax; allow it to fall out naturally. Also, avoid alcohol, smoking, and spicy foods.
Focus on moisturizing: It is recommended to use gentle moisturizing skincare products to relieve dryness and itching.
Long-Term Care
- Continue with sun protection:
Consistent use of sunscreen is an ongoing task to prevent long-term pigmentation problems.
- Follow your doctor's instructions:
Strictly follow the treatment plan recommended by your technicians to ensure the best treatment results.
Is 808nm diode laser hair removal safe?
I can assure you definitively that 808nm diode laser hair removal is very safe and comfortable.
Safety:
Melanin in hair follicles has a high absorption rate for 808nm wavelength light, and this wavelength can effectively penetrate the dermis to the hair follicle root, where hair follicles are most active.
Furthermore, 808nm laser has extremely low water absorption, meaning it can precisely target the hair follicle root without damaging surrounding skin tissue, achieving highly effective hair removal. This not only improves treatment safety and reduces the risk of burns but also ensures treatment effectiveness.
Comfort:
Taking Newangie's 808nm laser hair removal device as an example, it is equipped with an advanced dual cooling system that can rapidly cool to -27°C within one minute, minimizing pain during the procedure and improving treatment comfort. This ice laser hair removal machine also features a 1200W high-power laser handpiece with a lifespan of up to 50 million uses, ensuring not only high-efficiency hair removal but also reduced purchase costs.

How many sessions are needed?
On average, 808nm diode laser hair removal requires 3-6 sessions, with each session spaced 4-6 weeks apart. The specific number of sessions depends on various factors, such as the treatment area, hair color, hair density, the type of equipment used, and the individual's response to the treatment.
Areas with higher hormone levels may require more sessions, while some newer or more advanced 808nm diode lasers may require fewer sessions.
Is it truly permanent hair removal?
To be precise, based on current scientific analysis, truly permanent hair removal does not exist. Even advanced and highly efficient diode laser hair removal devices can only provide a maximum long-term hair reduction effect. Therefore, it's more accurate to say "permanently reduce hair" rather than "permanently remove hair."
Another factor that supports this view is the hair growth cycle. The hair growth cycle consists of three phases: growth phase, catagen phase and telogen phase. During the anagen phase, hair follicles are active and have high melanin content, making it the optimal time for hair removal. While laser hair removal can destroy hair follicles and significantly reduce the number and thickness of hairs, the hair on the skin is always in a "non-sensitive" catagen or telogen phase.
Therefore, multiple uses of the hair removal device are needed to cover all the anagen phases of the hair, gradually destroying the hair follicles and achieving a permanent hair reduction effect.
