Laser and photon therapy for skin rejuvenation

Laser and photon therapy at present, almost all laser and photon therapy are photothermal effects. Different technologies are used to treat different targets (purposes). From the perspective of symptoms, they can be classified as: pigmented spot treatment, vasodilation treatment, skin relaxation and wrinkle treatment.

Pigmented skin aging skin, especially photoaging skin, may have pigmented damage such as solar sunspots and uneven pigmentation. These lesions are usually located in the epidermis, so they can be treated in a variety of ways.

Vasodilation photoaging skin is often accompanied by some degree of telangiectasia. Vascular therapy lasers with wavelengths of 532nm, 585nm and 595nm (usually with a pulse width of milliseconds) can effectively treat dilated blood vessels. Since the dilated blood vessels are generally shallow and the pipe diameter is not very thick, 1064nm laser is usually not used. Common adverse reactions are skin burns and skin changes after burns.

Loose skin and wrinkles

It is generally acknowledged that the most effective treatment is laser skin resurfacing, but most doctors do not choose it because of safety problems. At present, there are many other treatment methods that can be selected. The curative effects on flabby skin are lattice laser, radio frequency and IPL. Long wavelength infrared lasers such as 1064nm, 1320nm and 1450nm also have good curative effects. In addition, 585nm and 595nm lasers are also effective for wrinkle treatment. These treatments can increase the amount of collagen in the skin and restore the structure of the skin. They can also be selected. At present, reports of the these methods of the treatment are all open studies with theout comparative observation, so it is difficult to determine which method is more effective and reliable. photodynamics therapy
