Q: Does photorejuvenation thin the skin? A: No. Many people think that photorejuvenation will burn the skin and destroy the already fragile stratum corneum, just like the wall skin being chiseled off, the thinner it gets. In fact, it is not, intense pulsed light (photorejuvenation) can activate the fibroblasts in the skin, increase the synthesis of collagen fibers and elastic fibers, hyaluronic acid (hyaluronic acid). After these newborn collagen and elastin are rearranged, the skin becomes more elastic, shiny and tight, wrinkles are reduced and pores are detailed. Therefore, instead of thinning the skin, laser rejuvenation will increase the thickness of the skin and make it firmer and more elastic, transforming it towards rejuvenation. Q: Will photorejuvenation make the skin sensitive? A: No. Many people think that photorejuvenation will lead to thinning of the skin, and without the protection of the “old skin”, the skin will become sensitive to heat and wind, and sensitive to cosmetics. This is far from the truth. Although photorejuvenation in the short term (7 days after the procedure) will accelerate the evaporation of water because of the photothermal effect, to promote the exfoliation of the stratum corneum, and sometimes the formation of small micro-scabs. However, all the “damage” is under control and will recover after 7 days. The newly healed skin has an intact structure (including the stratum corneum, which is replaced even without treatment) and healthy function, so photorejuvenation does not sensitize the skin. It is scientifically proven that Intense Pulsed Light repairs inflamed skin, reduces the release of inflammatory mediators, removes excess redness and enhances skin metabolism. Therefore, Intense Pulsed Light can treat the underlying conditions that cause skin sensitivity – seborrheic dermatitis, hormone-dependent dermatitis, acne and rosacea. Q: Will laser cosmetic treatments create dependence (addiction)? A: No. Many people think that the effect of laser cosmetic surgery is fine, but once you have it done, you will become dependent (addicted), and if you don’t have it done, it will rebound or worsen. Hold this view is not recognize the law of aging and the science of beauty. The aging of human skin is continuous, will not be suspended because of what, all we do is to make the aging of the footsteps to slow down some. Laser cosmetic treatments are like cleaning a dirty room, it will get better with a little treatment, but after a while it will still be dirty and still need to be cleaned. To get better results, multiple treatments or maintenance treatments are inevitably needed. This is not because we have become dependent or addicted to lasers, but rather the spinning of the wheel of time demands it. Q: Is one (session) of cosmetic laser treatment enough to get rid of my problem completely? A: No. There are only two answers to this question: 1. how many times the treatment should be done, and 2. whether the treatment can be maintained permanently. The human body is complex, each person’s response to a certain stimulus and its degree of difference, the same problem, some people three times to get good results, some people seven or eight times may not achieve good results. It is just like the amount of alcohol some people drink one or two white wine drunk, some people drink a catty not to fall. At the same time, many diseases are destined to its inevitable recurrence, the current treatment is only to improve, for example, freckles is a hereditary disease, the treatment can only be maintained for a period of time, and there is always a certain degree of recurrence afterward. That is to say, the idea of having a cure is unscientific. Q: I need to protect myself from the sun after laser cosmetic treatment, can I not protect myself from the sun if I don’t do the treatment anymore? A: No. After laser treatment, the color of the skin becomes fair and the pigment decreases, so the natural absorption of ultraviolet rays decreases and the protection function of the deep skin decreases. Therefore, it is necessary to strictly protect from the sun, otherwise new pigment spots will easily appear or hyperpigmentation will occur. After cosmetic is a clear requirement for sun protection, generally 3 months after treatment strict sun protection. However, it should be pointed out sun protection is not only after laser cosmetic treatment. Research shows that the ultraviolet rays in the sun are the main murderer of skin photoaging (pigmentation, redness, fine wrinkles). From the point of view of preventing photodamage and protecting the skin, it is necessary to pay attention to sun protection at all times and choose different sunscreens according to different environments.
