The first thing you need to do is to get rid of your skin. The skin is more dry? The skin is getting worse and worse. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. “, “IPL”, “Intense Light”, “OPT”, “DPL” “E Light” and even the name of some machines “King’s Heart” and “M22 (King’s Crown)” are all about it. Among them, “IPL” is the abbreviation of intense pulse light, “OPT” is the upgraded evolution of IPL, also known as perfect pulse technology, simply put, the difference between iPhone 6S and iPhone 6,” DPL” is the optimized intense pulsed light with a wavelength of 500-600nm, mainly for facial redness and other vascular problems. 1.Is photon the same as laser? Photon is different from laser, the wavelength of laser is single, like the familiar “black face doll” is 1064nm wavelength, while photon is a section of the spectrum of light, so its target is not as good as laser, but its wide range is higher than laser. You can understand the difference between them as the difference between “3 in 1 foundation” and “sunscreen”, “3 in 1 foundation” has multiple functions of foundation, concealer and sunscreen. The difference between a “3-in-1 foundation” and a “sunscreen” is that a “3-in-1 foundation” has multiple effects of foundation, concealer, and sunscreen, but its sun protection ability may not be as strong as a specialized sunscreen, nor is it as effective as a specific concealer, but it is superior in its multiple effects. Specific wavelengths of laser target specific skin problems, such as 532nm, 755nm, 1064nm nanosecond, picosecond laser mainly for pigment problems, 585nm, 595nm, 1064nm millisecond laser mainly for vascular problems. The photons with wavelengths of 500nm-1200nm have more comprehensive effects: destroying pigments, shrinking blood vessels, anti-inflammatory and sterilizing, controlling oil and inhibiting lipids, and increasing collagen synthesis. Therefore, photon therapy can simultaneously solve the three major problems of photoaging: increase in pigmentation, capillary dilation, and change in skin texture to achieve a rejuvenating effect, which is why it is called “photorejuvenation”, and that is why it is sought after by many people. The effect of photorejuvenation is mainly divided into two types: Type I rejuvenation: for pigmented skin diseases and vascular skin disease treatment. The main reason for this is that it is a good idea to have a good look at the skin. scarring, etc. The actual fact is that you can’t be sure that you’re going to be able to get a good deal on your own. The actual fact is that you can’t abuse photorejuvenation! It needs to be evaluated and treated strictly according to each individual’s skin condition. In fact, we can find that people whose skin becomes worse after photorejuvenation are often treated in certain “beauty salons”, especially those who have chloasma themselves. Photorejuvenation is on the one hand a very good treatment for pigmented skin conditions, but on the other hand has the potential risk of causing pigmented changes to the skin. At the same time, since the human body is very different, a doctor with extensive dermatological knowledge and treatment experience is needed to adjust the parameters of the equipment for different skin conditions in order to achieve a good treatment effect, and good equipment is also a very important factor in determining the treatment effect. Each person’s skin condition is different. A small number of people may experience hyperpigmentation, and a very small number of people may experience acne-like rashes and blisters. Of course, not everyone is suitable for photorejuvenation.
