In recent years, an emerging skin beauty treatment method in the beauty market quickly popularized and popularized, beauty seekers in an endless stream, which is familiar DD “photon beauty”. However, because many beauty seekers know little about photon beauty, coupled with some private beauty institutions in order to seek business profits and expand the publicity, but also to photon beauty treatment is covered with a veil of mystery. So, what is the photon beauty is how it is, here, I hope through some introduction for you to solve the doubts, unveil the mystery of this beauty technology. Photonic beauty initially emerged in the United States, two American doctors in 1998, the first discovered the strong pulse light in the skin photo injury and photo aging treatment has a good effect, and the first to apply it in the clinical. This technology began to appear in China after 2000, and because of its non-invasive, safe and good results, it was rapidly promoted in China, which is the current new darling of skin beauty treatment – photon beauty. The so-called photon actually refers to the intense pulsed light, the English for intense pulsed light, referred to as “IPL”, for the wavelength range of 500-1200nm composite light. The principle of photon cosmetology is that the strong pulsed light acts on the skin tissue to produce photothermal and photochemical effects. On the one hand, it can make the deep collagen fibers and elastic fibers rearrange and restore the elasticity, and at the same time make the vascular tissue function enhanced and circulation improved, so that the facial skin wrinkles are eliminated or reduced, and the pores are reduced; on the other hand, the strong pulsed light can penetrate the skin and be selectively absorbed by the pigment masses and blood vessels in the tissue, so that the blood is coagulated and the pigment masses and pigment cells are destroyed and decomposed without damaging the normal skin. Thus, it can achieve the effect of treating vascular proliferation diseases and pigmentation spots. So, what are the diseases or skin problems that can be improved by photorejuvenation? To be precise, the best indications for photorejuvenation are skin photodamage and photoaging caused by light irradiation and UV damage, including: vascular proliferative lesions, such as capillary dilation, hemangioma, nevus, nevus of wine, rosacea, red spots after laser resurfacing surgery, etc.; hair follicle sebaceous gland lesions; pigment proliferative skin diseases, such as freckles, coffee spots, pigmented nevi, pigmentation pigmentation, uneven skin color, etc. Photodamage of dermis and subcutaneous tissue, photoaging diseases, including wrinkle increase and fat metabolism disorder, etc., can be performed photon wrinkle removal and photorejuvenation. In addition, photorejuvenation can selectively destroy the hair follicles of the skin without damaging the surrounding tissues and can thus be used for hair removal. The reader may not be unfamiliar with laser aesthetics, but photons and lasers are both light, but they are two completely different concepts. There are many kinds of laser light-emitting substances, including solid (such as ruby), liquid (such as dye), gas (such as carbon dioxide) and semiconductors, etc. Different light-emitting substances can usually only excite a single wavelength of light, so they are mostly used for the treatment of a class of diseases. In contrast, the light source of photonics machine can emit a broad spectrum of light like sunlight, by using a filter to remove harmful ultraviolet and infrared light, and then use the middle section of visible light for treatment. Because of the large wavelength range of photonics machines, it is possible to treat a variety of lesions at the same time. In addition, with the higher power of the photonics machine, the treatment spot is larger, allowing a large area to be treated in a short period of time, while the laser cannot. Another major difference is that laser treatment tends to have a deeper effect on the skin, often requiring anesthesia, and there will be a process of skin breaking, nodulation and shedding after treatment; while photon treatment is milder, no anesthesia is needed, and the skin will not usually break or bleed after treatment, so it will not affect normal work and life, and you can easily get treatment without realizing it. Therefore, photon cosmetic technology is a non-invasive method of treating skin problems. Compared with traditional treatment methods, such as physical grinding technique, chemical peeling technique, CO2 laser or erbium laser cautery technique, etc., photorejuvenation has the advantages of non-invasive, non-cautery, as well as less post-operative complications and shorter recovery time; compared with the same non-invasive frequency doubling Nd:YAG laser (KTP laser), pulsed dye laser, 1064 nm Q-switched Nd:YAG laser The laser has the advantage of wider therapeutic applicability compared to single wavelength laser treatments such as KTP laser, pulsed dye laser, 1064 nm Q-switched Nd:YAG laser and 1320 nm long pulse width Nd:YAG laser. Therefore, as a novel and non-invasive method for the treatment of skin photodamage and photoaging, photon cosmetic technology has good prospects for aesthetic medical applications. However, there are two sides to everything. Due to the wide range of indications, photorejuvenation also has the disadvantage of being broad but not precise, and for a specific type of disease, its efficacy is often not the best. Due to the mild nature of phototherapy, the emergence of the treatment effect is also a gradual process, generally phototherapy requires 3 to 6 consecutive treatments, and the best effect will be achieved after a course of treatment. Each treatment lasts about 20 minutes, with 15-30 days between treatments. The price of photorejuvenation varies greatly depending on the equipment of the photorejuvenator. The price of a treatment can be as little as$300-500, or as much as$1,000-2,000. Generally, a course of treatment costs about$4,000-6,000 at a regular medical institution using imported photon equipment. Some female beauty seekers want to improve their face through photorejuvenation but are worried about spending too much, so they just do it once and rush off, which is difficult to achieve the desired effect, so it is also important to have an economic budget and evaluation before undergoing phototherapy. There are also some things that need to be noted about phototherapy, otherwise, it will also bring some impact on the effect of the treatment. For example, it is important to keep the skin clean before the treatment; professional treatment should be done with protective glasses to protect the eyes; immediately after the treatment, you can feel the skin texture is smooth, bright and firm, and the pores will be reduced, but if there is some redness, swelling, warm feeling is very normal, usually a few hours after the treatment that can gradually fade; if there is a deepening phenomenon of pigmentation within a few days after the treatment is also normal, after a week can be eliminated During the treatment period, do not take any other stimulating skin care, such as exfoliation, fruit acids, etc., and strengthen sun protection and moisturizing, the surface pigmentation spots may occasionally appear similar to the peeling phenomenon of nodules. Wash your face gently and let it peel off naturally. Phototherapy is gentle and non-invasive, so there are few serious side effects. Scarring, skin necrosis and permanent pigmentation changes are not usually seen if the photon machine is used correctly. The most common post-treatment reaction during normal treatment is transient erythema, which usually lasts about 2-48 hours and is occasionally accompanied by edema. Patients may experience a mild burning and pins and needles sensation during the use of high energy treatments. Patients with darker skin tones have a higher absorption rate of light and will experience transient purple palsy, crusting, and occasional pigmentation reduction or pigmentation aggravation if treated with high power short pulses. Overall, it is still very safe. In addition, the majority of beauty seekers should be reminded that photorejuvenation is not suitable for all people, for those who have light allergy, systemic or local inflammation, scar body, pregnant women, diabetic patients, blood clotting mechanism is not normal, the recent use of photosensitive drugs is not very suitable for photorejuvenation, born with a darker skin tone easy pigmentation people should also pay attention to prevent because of excessive energy density resulting in Burning. It is believed that with the increasing standardization of medical and cosmetic management, photon cosmetic treatment will also be more standardized, reasonable and rational than now.
