How does 808 laser hair removal work?
In the realm of modern aesthetics, 808 laser hair removal has emerged as a highly effective and popular solution for those seeking a long - term reduction in unwanted body hair. As a leading supplier of 808 laser hair removal equipment, I am excited to delve into the science behind this remarkable technology.
The Basics of Laser Hair Removal
Laser hair removal operates on the principle of selective photothermolysis. This concept was first introduced by Dr. Rox Anderson and Dr. John Parrish in 1983. The idea is to target a specific chromophore (a substance that absorbs light) in the body with a laser beam at a particular wavelength, while minimizing damage to the surrounding tissues.
In the case of hair removal, the chromophore is melanin, the pigment that gives hair its color. Melanin is found in the hair shaft, the follicle, and the bulb at the base of the hair. Different types of lasers are used for hair removal, each with a specific wavelength that is absorbed preferentially by melanin.
Why 808nm?
The 808nm wavelength is particularly well - suited for hair removal. At this wavelength, the laser light is absorbed efficiently by melanin in the hair follicles. The reason lies in the absorption spectrum of melanin. Melanin has a relatively high absorption coefficient at 808nm, which means it can absorb a significant amount of the laser energy.
Compared to other wavelengths, 808nm lasers can penetrate deeper into the skin. This is crucial because the hair follicles, especially those of terminal hairs, are located deep within the dermis. By reaching these deeper follicles, the 808nm laser can effectively target the cells responsible for hair growth.
Moreover, the 808nm wavelength is less likely to be absorbed by other chromophores in the skin, such as hemoglobin (the pigment in blood) and water. This reduces the risk of side effects like burns, blistering, and hyperpigmentation, making it a safer option for a wide range of skin types.
The Process of 808 Laser Hair Removal
- Initial Consultation: Before starting the laser hair removal treatment, a thorough consultation is necessary. The technician will assess the patient's skin type, hair color, and medical history. This information is crucial for determining the appropriate laser settings, such as energy density and pulse duration.
- Preparation: The treatment area is usually shaved to reduce the absorption of laser energy by the hair on the skin surface. A cooling gel may be applied to the skin to protect it from the heat generated by the laser and to enhance the comfort of the patient during the treatment.
- Laser Treatment: The 808nm laser device emits short pulses of laser light. When the laser beam is directed at the skin, the melanin in the hair follicles absorbs the energy. This energy is then converted into heat, which raises the temperature of the follicle. The high temperature damages the stem cells in the hair follicle, which are responsible for hair growth. As a result, the follicle is unable to produce new hair, or the hair that does grow back is thinner and lighter in color.
- Post - Treatment Care: After the treatment, the skin may be slightly red and swollen, similar to a mild sunburn. This usually subsides within a few hours to a few days. The patient is advised to avoid sun exposure, use sunscreen, and keep the treated area clean.
Factors Affecting the Effectiveness of 808 Laser Hair Removal
- Hair Color and Skin Type: The effectiveness of 808 laser hair removal is highly dependent on the contrast between hair color and skin color. Dark hair contains more melanin, which absorbs the laser energy more efficiently. Therefore, people with dark hair and light skin tend to have the best results. However, with advancements in technology, modern 808nm lasers can also be used safely and effectively on a wider range of skin types, including darker skin tones.
- Hair Growth Cycle: Hair grows in three phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). The 808nm laser is most effective during the anagen phase, when the hair follicles are actively producing hair and contain the most melanin. Since not all hair follicles are in the anagen phase at the same time, multiple treatment sessions are required to target all the follicles.
- Treatment Parameters: The energy density, pulse duration, and spot size of the laser are important parameters that can affect the effectiveness of the treatment. These parameters need to be adjusted according to the patient's skin type, hair color, and the treatment area.
