“Photon” has been a trendy topic in aesthetic medicine in recent years, and it is no longer a dream for beauty lovers to regain their former beauty. Since Dr. DR. Bitter, an American dermatologist, invented photon technology and used it to treat skin capillary dilation and hemangiomas, the indications for photon therapy have been expanding, and it can also effectively treat skin surface pigmentation, improve skin quality such as elasticity, luster and delicacy, and remove unwanted hair. The principle of photon cosmetic treatment: Photon therapy and traditional laser treatment are the same principle, both use the thermal effect generated by light to cause the target skin tissue to react and change. However, there are some differences in their physical properties, the laser is a single wavelength of monochromatic light, while photon is a strong pulse of light, is in a certain 500-1200nm wavelength of colored light, so in some countries also called it “color light rejuvenation”. Laser has a certain destructive effect on the affected skin tissue, and can be used to treat deeper skin diseases, such as nevus of Ota, tattoos, etc., while photon is a specific broad-spectrum color light, this specific broad-spectrum intense pulsed light can penetrate the epidermis and be absorbed by a large number of pigment groups in the skin tissue, without destroying the normal skin, so that the blood vessels are coagulated, pigment groups and pigment cells are broken and decomposed, thus achieving This is actually the principle of selective photothermolysis. Moreover, the action of intense pulsed light on skin tissue produces photothermal and photochemical effects, causing the collagen fibers and elastic fibers in the deep part of the skin to rearrange and regain elasticity, and at the same time, it also enhances vascular elasticity and improves circulation. The combination of these effects allows the elimination or reduction of facial skin wrinkles and pore reduction to be achieved very quickly. The epidermis will not be affected, and there will be no thinning of the skin and other phenomena. Indications for photorejuvenation: 1, vascular lesions, including capillary dilation, erythema, red face, rosacea, etc., need to be treated once every 4-6 weeks, 5-8 times as a course of treatment; 2, pigmented lesions, including facial pigmentation spots, seborrheic keratosis (age spots), freckles, need to be treated once every 3 weeks, 5-8 weeks as a course of treatment; 3, changes in skin structure, including fine wrinkles, skin laxity, pore size and depressed scar after acne, need to be treated every 3 weeks, 5-8 weeks as a course of treatment. 4, hair removal patients should be treated every 3-6 weeks, every 3-5 times for a course of treatment. Contraindications to photorejuvenation: 1. Photorejuvenation should be avoided if you have received or are likely to be exposed to sunlight after treatment within one month. 2. Absolutely contraindicated during pregnancy. 3.People with a history of epilepsy, diabetes, blood disorders, etc. can choose other cosmetic treatments. 4.Patients with serious heart disease and high blood pressure must be cautious, otherwise there may be serious effects. 5, scar body and treatment site skin infection patients should not do. 6.People with photosensitive skin and those who have used photosensitive drugs should avoid doing photorejuvenation. 7.Suspected skin cancer may not be done. 8. Those who want to rejuvenate their skin with photorejuvenation should not do it. The skin rejuvenation is safer and less painful than other skin rejuvenation methods, and is a non-invasive operation. A very small number of people may experience redness and blisters, and a small number of people may also experience pigmentation.
