With its unique wavelength advantage, 450nm laser technology has shown excellent results in the field of skin disease treatment, especially in the treatment of acne, pigmentation and vascular skin diseases. 450nm laser technology can accurately act on the diseased tissue, achieve effective treatment through photothermal effect, and reduce damage to surrounding healthy tissue. However, although laser treatment is good, its safety cannot be ignored. During the treatment process, strict laser protection measures must be taken to ensure the safety of patients and medical staff.
450nm Treatment Principle
The basic principle of 450nm laser treatment of skin diseases is that its specific wavelength of light can penetrate the surface of the skin and directly act on the diseased tissue. This wavelength of laser has a high photon energy and can be efficiently absorbed by target chromophores such as pigment particles in the skin or hemoglobin in blood vessels. The absorbed laser energy is converted into heat energy, causing the target chromophore to rapidly heat up, expand and explode, thereby destroying the diseased tissue. At the same time, the thermal effect of the laser can also promote local blood circulation, accelerate metabolism, and facilitate the disappearance of inflammation and tissue repair.
Specifically, when treating inflammatory skin diseases such as acne, 450nm laser can inhibit the growth of Propionibacterium acnes, reduce inflammatory reactions, and promote the healing of acne wounds. When treating pigmented skin diseases, laser can break up pigment particles and excrete them out of the body through selective photothermolysis, thereby achieving the effect of lightening spots and whitening skin.
450nm Application Areas
1. Acne treatment: 450nm laser can inhibit the activity of Propionibacterium acnes and reduce the release of inflammatory factors, thereby effectively alleviating acne symptoms. At the same time, laser can also promote the regeneration of skin collagen and improve acne pits and acne marks left after acne.
2. Pigmentation treatment: For pigmented skin diseases such as freckles and chloasma, 450nm laser can break up pigment particles and excrete them out of the body through selective photothermolysis, thereby achieving the effect of lightening spots and whitening skin.
3. Treatment of vascular skin diseases: Although 450nm laser is not the first choice for the treatment of vascular skin diseases (because its wavelength is not the optimal absorption peak of hemoglobin), in some cases, it can also be used as an auxiliary treatment for superficial vascular skin diseases, such as telangiectasia.
How to choose laser protective glasses for 450nm lasers?
1. Wavelength matching: Make sure that the protective glasses can provide effective protection for 450nm lasers. Lasers of different wavelengths have different mechanisms of damage to the eyes, so it is important to choose protective glasses that match the treatment wavelength.
2. Optical density (OD) value: Optical density is an important indicator to measure the protective ability of laser protective glasses. For 450nm lasers, it is recommended to choose protective glasses with a sufficiently high OD value to ensure that the laser energy can be fully absorbed and the eyes can be protected from damage. However, it should be noted that too high an OD value may affect the clarity of the field of vision, so it is necessary to find a balance between protection effect and comfort.
3. Material and process: The lenses of laser protective glasses are usually made of special materials, such as polycarbonate, glass, etc., which have good absorption and reflection properties. At the same time, JTBYShield Laser Technology Co., Ltd.'s laser protective glasses strictly follow the EN207 standard to produce laser protective glasses and provide high-quality protective glasses.
4. Comfort and fit: Since laser treatment may take a long time, the comfort and fit of laser protective glasses are also very important. Choosing glasses made of lightweight, soft, and breathable materials, as well as frame designs that fit your face shape, can reduce discomfort when wearing. At the same time, make sure that the glasses fit the face tightly to prevent light from leaking in from the sides or above.
