1. Different principles
Photodynamic instrument: This product uses high-purity narrow-spectrum genetic biological light generated by high-tech chips to quickly act on the mitochondria of the "lungs" of cells, producing Photochemical reaction - enzymatic reaction,
increases the activity of catalase (Catalase) and superoxide dismutase (SOD), which serve as cell "guards" and "cleaners", and increases cell energy generation source Decompose adenosine triphosphate (ATP), increase glycogen and protein content, thereby promoting cell metabolism and synthesis.
Stimulate the secretion of basic fibroblast growth factor (BFGF) and epidermal growth factor (EGF) in the body, so that Collagen fibers and elastic fibers are rearranged to block and eliminate the formation of melanin, kill Propionibacterium acnes, and eliminate inflammation, thereby achieving the effects of whitening, removing freckles, removing acne, removing wrinkles, and rejuvenating the skin.
Laser instruments: In 1983, Anderson RR and Parrish JA proposed the theory of selective photothermal action—the "photothermal separation" theory, which means to select appropriate lasers based on the biological characteristics of different tissues. Wavelength, energy, and pulse duration are selected to ensure effective treatment of diseased tissue while minimizing damage to surrounding normal tissue.
2. Different functions
Photodynamic instruments: beauty treatment, whitening and wrinkle removal, freckle removal and acne removal;
Insomnia treatment, sleep disorders, depression, soothing Stress reduction;
Sub-health treatment, neck, shoulder and waist strain, gynecological and male diseases.
Laser equipment: In the early 1990s, Q-switch laser was used to treat pigmentary diseases such as nevus of Ota, tattoos, etc., and nearly perfect therapeutic effects were achieved; in the mid-to-late 1990s, variable pulse width 532nm laser was used to treat blood vessels. Diseases have also achieved good results.
3. Different technologies
Photodynamic instrument: switching constant current circuit design, which can achieve low voltage, low current, low function, low heat, high light intensity, high efficacy and high comfort , high security.
Unique chip technology, using chips imported from the United States, leads the country in performance indicators such as optical power, wavelength, and purity. The unique dual-chip voltage stabilizing patented technology and packaging technology ensure stable product performance, wide voltage adaptability range, and round and uniform light spots.
The patented heat dissipation technology of the irradiation head of aviation materials breaks through the traditional micro-motor fan heat dissipation, achieving noise-free and ultra-long service life.
Humanized design, patented arm design and whole machine patented design highlight noble quality. It can be freely controlled in 360 degrees, with adjustable power pulse light control, timing control, MP3 patented sleep music playback, remote control operation, and is comfortable and suitable for home and office use.
Laser instrument: The photothermal effect is divided into thermal effect, thermal coagulation and thermal exfoliation. Thermal effect: When the temperature rises to a certain level, about 60℃-65℃, the collagen fibers can shrink to 1/3 of the original length and the diameter of the collagen increases, and the integrity of the corresponding tissue structure is not affected; Thermal coagulation: When When the temperature is higher than 75°C,
and the time is long enough, it will cause thermal coagulation of the tissue. A certain amount of dispersed thermal coagulation will bring about a lasting and obvious skin reconstruction effect; thermal peeling: when the temperature is greater than 300 ℃ and for enough time, heat will cause tissue vaporization, combustion, molecular cleavage and plasma formation, leading to tissue trauma.
