808 nm diode laser

Types of 808 nm diode lasers

The 808 nm diode laser is a cosmetic device that emits a wavelength of light used in laser treatments. It has different types categorized based on usage. They include the following:

• Laser hair removal machines: These 808 nm diode lasers are primarily used in clinics and salons to remove unwanted hair. They operate by targeting the melanin in hair follicles, which causes the follicles to weaken or destroy, resulting in the permanent reduction of hair growth. The 808 nm wavelength is ideal for penetration and effectively treats various hair and skin types.
• Home-use laser hair removal devices: These are smaller, portable, and designed for self-treatment at home. They still use the 808 nm wavelength to offer hair removal results. The hand-held units are less powerful than professional gear but are more practical and economical.
• Laser acne treatment devices: Some 808 nm diode lasers can be used to treat acne. They work by killing the bacteria that cause acne and shrinking the oil glands in the skin. Laser acne treatment devices are used to remove scars caused by acne.
• Laser wrinkle reduction: An 808 nm laser can be used to treat wrinkles by stimulating the production of collagen and elastin in the skin. The laser can also be used to treat other signs of aging, such as age spots, uneven skin tone, and sagging skin.
• Laser skin rejuvenation machines: These machines combine acne treatment, wrinkle reduction, and hair removal. They are mostly found in clinics and hospitals and use different types of handpieces to treat various skin conditions.

How to choose 808 nm diode lasers

Before buying an 808 nm diode laser for commercial use, consider the treatment parameters, such as energy fluence, pulse width, repetition rates, and wavelength. It is essential to understand the skin types and hair characteristics to provide effective treatment. Also, check the equipment's wavelength, which ranges from 755 nm, 808 nm to 1064 nm. The 808 nm laser is a middle ground that can treat different hair and skin types. An 808 nm diode laser with a larger handpiece can cover more treatment areas within a short time.

Look at the laser energy output. The higher the energy output, the better the treatment results. For a painless procedure, consider models that have a dynamic cooling system or a 40 mm sapphire tip that provides constant cooling. People with different skin types can use the device. Look for models with adjustable pulse durations to suit different skin types and hair textures. Choose lasers with a continuous wave or a high pulse repetition rate to improve treatment speed and outcomes.

Other factors to consider are the design and size of the handpiece, manufacturer reputation, warranty, and technical support. 808 diode laser machines are classified as either portable or desktop. Portable machines are more convenient for mobile therapists.

How to use, install & product safety

How to use

• Prepare the Skin: Hair should be clean and shaven two days before the treatment. Avoid sun exposure, tanning beds, and any skin treatments like chemical peels, microdermabrasion, or other laser applications at least two weeks before the session. Ensure no perfumes, deodorants, makeup, or lotions are on the skin before the treatment.
• Protect the Eyes: Safety glasses are worn by both the operator and the patient to protect the eyes from potential laser damage.
• Test Spot: A test spot is done to determine the appropriate energy level for the treatment. This is based on the patient's comfort level and the effectiveness of the treatment.
• Cooling Mechanism: Some machines have a cooling mechanism, such as cold air blowing onto the skin, to protect the skin from laser heat. Other methods include cooled gel application or contact cooling.
• Handpiece Movement: The technician moves the handpiece over the treatment area, delivering laser pulses. They might apply topical creams like aloe vera or ice cubes to cool the treated area between pulses.
• Session Duration: Depending on the treatment area, sessions can last from 15 minutes to over an hour. Smaller areas like the upper lip take less time, while larger areas like the back can take longer.
• Post-Treatment Care: After treatment, creams like aloe vera, hydrocortisone, or B-12 are applied to the skin to soothe it. Patients are educated on proper post-treatment care, and follow-up appointments are scheduled if needed. Patients are advised to avoid sun exposure and wear sunscreen for a month after the treatment.

Product Safety

• Skin Type and Color: Diode lasers work best with light skin and dark hair. Treatments can still be performed with darker skin, but settings will be adjusted to protect the skin.
• Hair Growth Cycle: Treatments are done every 6 to 8 weeks to allow the hair to grow into the anagen phase, or active growth phase. It may take 6 to 8 treatments to see a significant reduction in hair growth. Some patients may require more treatments depending on their hair growth cycle.
• Pre- and Post-Care: Following pre- and post-care instructions is important. Avoid sun exposure and skin treatments before and after treatment. Avoid heat, tight clothing, intense exercise, and sun exposure for 48 hours after treatment.
• Side Effects: Side effects like redness, swelling, and bumps may occur after treatment but will resolve quickly. Rare side effects like blistering and hyperpigmentation may also occur. Patients should be informed that hair may seem to regrow after treatment but will fall out within 10 to 14 days.

Functions, features, and design of 808 nm diode lasers

The 808nm diode laser has a high hair reduction rate. It takes less time to treat a larger area. This makes it suitable for use in clinics and hospitals. The handpiece has a cooling mechanism. It provides cooling to the skin before, during, and after treatment. This ensures client comfort and safety. Some machines also have a sapphire crystal that aids cooling.

The 808 laser works on all hair types and colors. It is effective on dark and light hair. The laser targets the melanin in the hair follicle. It destroys the ability of the hair to regrow. The treatment is fast and long-lasting. After a few sessions, clients notice a significant reduction in hair regrowth.

There is no need for special care or treatment after using the laser. Clients can go about their normal activities. There is no risk of damage to the skin or blisters. The laser can penetrate deeper into the skin to reach the hair follicles. It ensures permanent hair removal.

Q&A

Q1: What is the difference between 808 nm and 755 nm diode lasers?

A1: The 808 nm diode laser operates at a longer wavelength than the 755 nm laser. This enables the 808 diode laser to penetrate deeper into the skin, making it more effective for treating coarse, thick hair. The 755 nm laser is better suited for finer, lighter hair and works at a more superficial level. The 808 diode laser can be used on all hair types and colors, while the 755 nm laser is most effective on light hair.

Q2: Does the 808 nm diode laser hurt?

A2: Pain perception varies from person to person. Most people report only mild discomfort during laser hair removal treatment. The feeling is similar to that of a rubber band snapping against the skin. Some newer 808 nm diode laser machines have a cooling feature that numbs the treatment area and reduces pain.

Q3: How long do results from 808 laser treatment last?

A3: Results vary depending on the individual's hair type, texture, and growth cycle. After completing the recommended treatment sessions, which can range from 6 to 12 sessions, patients may experience permanent hair removal. Those who require periodic touch-up treatments are usually once every one to two years.

Q4: Can the 808 nm diode laser be used on all skin types?

A4: Yes, the 808 nm diode laser has adjustable settings, making it suitable for use on light and dark skin. The laser technology is designed to target hair follicles without causing damage to the surrounding skin.
