When the ultrasonic knife, which can lift and tighten and remove wrinkles, meets photorejuvenation, which has the same function, what kind of spark will be created? Needless to say, the effect will definitely be doubled, twenty years younger! But in fact, they can’t rub together because they can’t do it together! If you force them to do it together, you’ll only lose your wife (wallet) and lose your army (face). But why can’t you do it together? It’s all about the degree of damage to the skin. 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. On the one hand, it rearranges the collagen and elastic fibers in the deeper part of the skin and restores elasticity, while enhancing the function of vascular tissue and improving circulation, resulting in the elimination or reduction of facial skin wrinkles and pore size. On the other hand, the specific broad spectrum of strong pulse energy penetrates the skin tissue and is selectively and preferentially absorbed by the pigment mass and its blood vessels in the tissue, which causes the blood to coagulate and the pigment mass and pigment cells to be destroyed and decomposed without damaging the normal skin, thus achieving the effect of treating capillary dilation and pigment spots. It is clinically proven that this therapy has good therapeutic effect on skin aging, pigmentation, pigmentation, freckles and facial capillary dilation, rosacea, etc. caused by sunlight exposure. The photorejuvenation technology has good safety and reliability features and does not cause harm to the patient’s skin stratum corneum, while the technology itself does not have side effects. Although ultrasonic knife and photorejuvenation have different focus, they do not conflict with each other and can be combined, but it is usually not recommended to treat both on the same day. The ultrasonic knife can cause different degrees of damage to the facial skin tissue because of its deeper level of action. Although the technology of photorejuvenation is more mature, with less damage to the skin, fast results, no rebound and high safety, it still takes about 2 weeks to recover. So if you do both together, it will only increase the damage and affect the recovery effect of the skin. And too frequent epidermal thermal stimulation may aggravate the risk of localized post-operative skin complications, such as erythema, blistering, and even scarring. So how long do you need to space out the two? This time is subject to the specific recovery time of the candidate, but in general, if photorejuvenation is done first, due to its higher safety, it is generally recommended that the candidate should recover for at least 2 weeks before doing ultrasonic knife. If the ultrasonic knife is done first, it is advisable to take more than 1 month between skin rejuvenation sessions because of the damage to the skin. It takes time to get back to the top of your face, and you can’t ignore the recovery of your skin even if the beauty program is omnipotent, after all, the condition of your skin is the root of your beauty. There are also any claims of risk-free beauty projects are exaggerated, do not easily believe, must be careful to make a decision. Don’t lose your rational thinking for the sake of beauty, after all, health should always come first compared to beauty. References [1] Kang Qiao, Wen Yanlin, Jin Yan, et al.
