One of the principles of the photorejuvenation method is to use photothermal and photochemical effects to produce stimulation of collagen and powerful proteins to regenerate and reorganize collagen and elastic fibers, repair them while making the tissue function stronger and circulation improve, not only to reduce pores but also to tighten the skin, get rid of fine wrinkles and increase the skin’s luster. Secondly, photorejuvenation is a non-invasive skin medical technology. An important reason for the rapid rise of photorejuvenation technology is that it is non-invasive, patients have no significant discomfort after the treatment and no obvious adverse reactions on the face, while pigmented lesions such as freckles, chloasma, age spots and sun spots on the face improve or disappear. Therefore, it has more comprehensive treatment efficacy and can improve skin quality, reduce wrinkles, remove pigmentation, remove red blood, shrink pores, and whiten skin from the base layer, and it can have tight and bright skin in one session or 1-6 sessions. What skin problems can be treated by photorejuvenation? 1, pigmented diseases: melanin is the target of strong pulse light action, melanin vesicles, melanin masses selectively absorb the energy of photons and produce a blasting effect. The more superficial pigmented spots are broken up to form melanin dust, which can fall off from the skin surface with dander after about 3-7 days. The deeper pigmentation is also broken into dust after absorbing longer wavelength photons, which can be engulfed by phagocytes in the skin and gradually discharged from the body with lymphatic circulation and blood circulation. So it can treat various pigmentary diseases including freckles, age spots, sun spots, chloasma, pigmentation, dark circles (under the eyes), uneven skin tone, etc. 2, vascular diseases: hemoglobin in red blood cells is also the target of strong pulse light action, which can selectively absorb certain wavelength spectrum of intense light, producing thermal coagulation effect and transferring heat to the epithelial cells of capillaries, causing segmental coagulative necrosis. These small coagulated blood filaments are gradually removed by the phagocytic system of the skin, and the effect of removing blood filaments, vasodilatation of rosacea, lightening of acne purplish red marks, and various early damage erythema can be achieved. Generally speaking, small, superficial blood vessels absorb photons of short wavelength better; thick, deep in the blood vessels absorb photons of long wavelength better. Intense pulse light contains light from short wavelength to long wavelength, so it has a therapeutic effect on all hyperplastic blood vessels. 3, skin photoaging: UV rays in sunlight can destroy collagen fibers and elastic fibers in the dermis, producing photoaging phenomenon, making the skin loose, producing fine wrinkles and discoloration. As age increases, the degree of photoaging gradually increases, and the degenerated collagen fibers and elastic fibers break off to form larger wrinkles. Intense pulsed light stimulates fibroblasts in the dermis to synthesize new collagen fibers and elastin fibers. And the new collagen fibers and elastic fibers are rearranged to be more dense and neat. Thus, it can achieve the effect of skin rejuvenation, skin tightening, wrinkle removal, wrinkle reduction and pore reduction. 4, scar repair: after the fibroblasts in the scar tissue are stimulated by the strong pulse light, the inner repair function of the skin is awakened and the scar starts to repair again, with the increase of treatment times, the effect of reducing or disappearing is gradually achieved. For caesarean section and various surgical suture scars, the best treatment time is about 1 week after stitch removal, and burn and trauma scars can get the best effect only when they start early after skin healing. 5.Hair removal: The growing hair follicles contain high density melanin vesicles. The melanin vesicles absorb the photon energy and then destroy the hair follicle’s hair-growing tissue through selective photothermal action, thus achieving the effect of hair removal. For fine hairs, photon hair removal is better than laser hair removal. And dark-skinned people can choose laser hair removal. 6, acne and its scar, red and black marks. Photon can indeed achieve the effect of skin rejuvenation so quickly, but can the effect last? Will it rebound? The actual fact is that you can find a lot of people who are concerned about the rebound of photorejuvenation, and experts point out that the ultimate effect of photorejuvenation depends on the doctor’s level of operation, the choice of equipment and the correct skin care after treatment. The actual fact is that you can find a lot of people who are not able to get a good deal on this kind of thing. In addition to choosing good professional equipment, it also requires a professional who understands technology and skin science to operate it safely and effectively without harming the skin. In addition, if you want to maintain a healthy skin condition after this treatment, you need to take perfect care of it in your daily life. Therefore, it is also very important to have an experienced physician to give professional guidance to the skin care of the treated person after the treatment, so that the skin can be prevented from too much external influence and thus maintain a healthy and tender condition for a long time. In addition, as there are great differences between individuals, people who are allergic to light, have local and systemic inflammation, immune system deficiencies, scarring, recent use of photoallergic drugs, pregnant women, abnormal blood clotting and those who are using aspirin or antioxidants are generally not suitable for photorejuvenation. One of the revolutionary innovations used in LumenisOne, the world’s most advanced “King’s Manner”, is its OPT technology (Perfect Pulse Technology), the fourth generation of intense light technology. The third generation and the earlier second generation of intense light technology are not fully controlled by the current, there are energy spikes and attenuation problems, even high and low; the energy spikes of pulses are prone to skin burns and pigmentation, while the attenuated pulse energy is often lower than the set value, which is not good for the treatment operation. The LumenisOne system with OPT technology completely solves the problem of unstable energy of the previous generations of IPL, with 9 groups of capacitors to fully stabilize the current and pulse energy, so that the energy output is a regular square wave from beginning to end, without spikes, no energy spikes will not cause complications such as burning and pigmentation. The square wave has two advantages, the energy does not decay and always remains consistent. The spike wave inevitably decays in energy, and when the energy is too weak, there is no treatment effect. At the same time the fully digitally controlled, personalized treatment allows the doctor to be truly comfortable with the treatment, selecting parameters according to each patient’s needs, skin tone, skin type, lesions and treatment response, performing different continuity of treatment, adjusting the treatment parameters upwards as the number of times goes up, in short, surely finding the most effective parameters within a safe range. Personalization makes for good safety and high treatment efficiency. Therefore, the obvious effect of OPT technology, as reflected in clinical practice, is that it significantly reduces the incidence of complications and fully enhances the confidence of physicians and patients in photon (IPL) treatment. The safety and ease of use are further enhanced by several of LumenisOne’s advanced designs. The system is automatically calibrated each time it is turned on, and a mandatory calibration is performed after every 5,000 pulses, providing further assurance of pulse energy stability. and detailed reference.
