1064nm Laser in Cosmetic Dermatology
What are the characteristics of 1064nm wavelength lasers?
- Introduction to 1064nm Lasers
1064nm wavelength light belongs to the infrared spectrum and is a special wavelength that can be simultaneously absorbed by water, hemoglobin, melanin, and collagen fibers in the dermis. However, the absorption of 1064nm by these three chromophores is relatively weak, therefore, 1064nm lasers have deep penetration and can treat vascular, pigmented, and collagen diseases in the dermis.
2.1064nm can be divided into:
Picosecond lasers: Picosecond pulse width. They act efficiently on pigment particles through photothermal and photomechanical effects. Picosecond lasers have shown efficacy in treating tattoos, pigmented diseases, and facial rejuvenation.
Q-switched lasers: Nanosecond pulse width. They are the preferred choice for treating deeper pigmented skin abnormalities such as melasma, nevus of Ota, and blue-brown nevus.
Long-pulse lasers: With microsecond-level pulse widths, they can induce thermal damage to target cells. The pulse width parameters are adjustable, making the product suitable for a wide range of clinical applications, and offering high safety and comfort during treatment.
1064nm laser is a highly penetrating and widely applicable cosmetic treatment, particularly effective in improving deep pigmentation problems and vascular diseases, while also providing skin rejuvenation and firming effects. It precisely targets the intended tissue through selective photothermal action, causing minimal damage to surrounding skin, resulting in a short recovery period, and is suitable for various skin types.
Deep penetration: Reaches the dermis and even subcutaneous layer to address deep pigmentation issues (such as melasma) and dilated blood vessels (such as rosacea).
Minimal epidermal damage: Lower melanin absorption rate reduces the risk of epidermal burns, making it more suitable for people with darker skin tones.
Multifunctional: One device for multiple uses; adjustable pulse width and energy to address various issues (such as pigmentation removal, skin rejuvenation, and hair removal).
Stimulates collagen regeneration: Thermal energy promotes collagen remodeling in the dermis, resulting in long-term skin improvement and delaying skin sagging and fine lines.
