[Social Habit] Laser treatment can make the skin sensitive. My so-and-so friend’s skin became very thin, sensitive and easily red after laser treatment, and I was afraid to do it. [Expert Review] Proper laser treatment usually does not cause skin sensitivity. Laser assisted treatment of skin sensitivity has a very good effect. 1, the skin will not become sensitive after laser treatment: first, the general laser treatment has high selectivity, can accurately treat the lesion without harming the skin, there is almost no or only extremely slight effect on our normal skin, so it will not cause skin sensitivity. With exfoliative fractional lasers, temporary skin sensitivity may occur (incidence about 10%) due to partial epidermal peeling, but it can be repaired quickly. However, I also disagree that cosmetic lasers should be done too frequently, as it is true that some patients’ skin function can be affected to some extent. Then we need to clarify a demarcation, how often is considered frequent? First of all, our skin has a normal metabolic time, usually about 28 days, which is actually the epidermal turnover time. I suggest that if you use high energy laser treatment, it should not be shorter than one month. In fact, the interval of many of our treatments such as vascular class is one month, the interval of some exfoliative laser treatments such as acne depression scarring is up to 3 months, and the interval of some diseases such as nevus of Ota treatment is even up to 3-6 months. Large light spot low energy treatment for melasma may have a shorter treatment interval, but because of the lower energy used, skin sensitivity will not generally occur. 2.Sensitive skin can be treated with laser: A large number of clinical studies have proved that low-energy photons or laser can effectively treat facial flushing and capillary dilation of sensitive skin. And because the treatment energy is very low, the treatment process will not cause special discomfort, is a very gentle method. The treatment principle is attributed to the light-regulating effect: it is the modulating effect of light on the immune function of the skin, which can reduce the sensitivity of the skin and enhance the barrier function of the skin. 3, then why would someone say that after doing laser will make the skin become sensitive? Laser treatment should not be too frequent and the treatment energy should not be too high. In fact, many patients who complain about their skin becoming sensitive after treatment are because they are treated in some irregular institutions. Due to the lack of mastery of skin knowledge, laser equipment, technology and the pursuit of maximum benefits, they treat patients too frequently, massage, spot removal, exfoliation and even the use of hormones and other substances to whiten the skin at the same time as laser treatment, which is what causes the skin to become sensitive “culprit”. There are even some institutions that use machines that are just cheap and irregular. Here is an example – “E” light skin rejuvenation treatment We have many patients coming to our treatment room who have severe hyperpigmentation, hypopigmentation, facial flushing and capillary dilation after doing the so-called laser beauty treatment in beauty salons. Many of them said that they had done the very hot E light. 1. Can E light be treated in beauty salons? The trend is that E light is becoming more and more famous under the publicity of beauty salons, and it even has the tendency to overtake “photorejuvenation” in the awareness of women who love beauty. E light is a medical device that requires a professional doctor to evaluate and operate the patient. Now it has eMatrix, eMax and the latest VelaShape III. This technology is more effective for skin rejuvenation. Light energy can deal with superficial abnormal pigments and visible vascular lesions, while RF is mainly used to heat deep tissues and cause new collagen formation for improving fine wrinkles. However, the treatment requires the professionalism of the doctor, the precision of the equipment and the proper adjustment of the treatment energy by the doctor according to the patient’s skin response. In some informal institutions, the treatment may have the following problems: 1. equipment problems, a good E light equipment is expensive, some small beauty salons can not provide enough funds to buy, what they call E light equipment is not clear; 2. technical problems, the hardware is enough, but also need strong enough software conditions to achieve good treatment results, an experienced professional laser treatment doctor is An experienced professional laser treatment doctor is a necessary condition, and can even be said to be the key to determine the treatment effect, no relevant qualifications of cosmetologists they are clear enough about the structure of the skin? Is the principle of equipment treatment clear? These questions should be thought about before the treatment. If the treatment process is too high energy or negative pressure attraction is too large, easy to redness and swelling after surgery, generally last a few days will completely subside; but in serious cases may also appear obvious blisters, if not proper care, it may appear to stimulate infection, so that pigmentation spots or scarring. 2, some seekers in the beauty salon after the treatment of skin better, but why not long after the skin began to become sensitive intolerant it? Some beauty salons, in order to pursue the maximum profit, often use their three inches of food to persuade you to continue treatment, especially when you see a little skin improvement at the beginning of the treatment, you can not help but fall into their “trap”. However, we know that although E light and some other laser treatments are non-ablative treatments, the recovery time is short, complications are few, and the skin barrier can be restored soon with proper post-operative care without causing skin sensitivity. However, for a period of time after surgery, the skin barrier, moisturizing and sun protection will be damaged to a certain extent, so laser treatments require a certain treatment cycle and should not be treated too frequently, not less than one month. As these non-exfoliating treatment after surgery, there is no trace, so often can not attract attention, at this time, you then massage, chemical peeling and other treatments, and even some use of cosmetics containing hormones, are further damage to the normal structure and function of the skin, and in the long run you may have skin sensitivity. So you hear others say often do beauty laser skin will become sensitive should think about her treatment place, the interval cycle and post-operative care issues. 3, for skin sensitivity, E light is a good adjunctive treatment. Skin sensitivity requires the adjustment of lifestyle habits, diet and other aspects, auxiliary medical skin care products, and in severe cases, drugs and laser, photon, photoelectric synergistic technology can be used to treat. The laser treatment needs to be carried out in regular hospitals and clinics. The right laser treatment will not cause skin sensitivity, while it can treat skin sensitivity, but sensitive skin requires comprehensive treatment and care
