The concept of skin rejuvenation treatment for photo-aged skin is a hot hype in the field of cosmetic dermatology right now. As cosmetic laser practitioners who treat skin, we have a wide variety of patients every day who request improvements in skin texture, color, pore size, blood vessels and wrinkles. We have worked hard to enhance and refine a variety of treatments including chemical peels or non-peel peels, various visible light and near infrared light laser resurfacing. Over a decade ago, Dr. Patrick Bitter, Jr. first treated 49 patients with standard parameters of intense pulsed light, a retrospective study that brought the concept of photo rejuvenation to a whole new level. As medical technology continues to evolve, the capabilities of photorejuvenation devices are changing rapidly. In clinical treatment photorejuvenation devices can effectively reduce capillary dilation and improve fine wrinkles in the skin. It is effective in the treatment of freckles in pigmented skin diseases. Photorejuvenation technology is a kind of skin rejuvenation treatment using non-coherent intense pulsed light technology (IPL) in a non-exfoliating manner with low energy density. Intense pulsed light emits a spectral range of 560-1200nm, or 570-950nm. Its longer wavelengths can lead to significant improvement in photodamage and aging of the skin, while shorter wavelengths can treat pigmented and vascular lesions of the skin. The main reason for reduced skin elasticity and wrinkles is the aging and thinning of the collagen fiber layer of the skin. The broad spectrum light of photorejuvenation contains wavelengths that penetrate the epidermis to heat the collagen layer. It is scientifically proven that when collagen is heated to a certain degree, the collagen fibers will rearrange collagen and produce a certain degree of proliferation, making the collagen layer thicker, thus increasing skin elasticity, reducing wrinkles and shrinking pores. How photorejuvenation treatment is performed: 1. Before treatment, cold gel is usually applied to the area to be treated, and special glasses are required to protect the eyes from light exposure. 2. During the treatment, the light guide crystal of the photorejuvenator is placed lightly on the skin to be treated, and the pulsed light is released. There will be a slight pain, which is generally tolerable. The skin has a slight redness and burning sensation, generally do not need to deal with, if necessary, the use of ice bags cold compress to reduce the surface temperature of the skin, an hour later gradually return to normal. 3.After treatment, clean the skin and apply a moisturizing and soothing mask externally. However, sun exposure should be avoided, do not use irritating skin care and cosmetics for 24 hours, it is recommended to use water, cool water to cleanse the face. Antioxidants such as VC and VE can be taken orally. The whole course of treatment usually requires 5-6 treatments with a treatment interval of 3-4 weeks to achieve the best results. Each treatment takes about 15-20 minutes. Most importantly, the treatment requires no downtime and you can resume your normal life and work immediately after each treatment is completed. 4.Is there any possibility of side effects? Due to the small amount of energy used in the photothermal treatment technology, the occurrence of side effects is very rare. Slight redness of the treated area may occur, but such reactions usually disappear within a few hours. Minimizing sun exposure before and after each treatment will reduce the chances of side effects. After treatment, you can quickly return to your daily work and life.
