Picosecond freckle;
I heard of laser when I was very young, and I was afraid of picosecond laser, because its shock wave time is seven times that of ordinary laser. Otherwise, the principle is the same. They are all based on the theory of selective photothermal effect, using powerful instantaneous destruction. Generally, the "pulse width" is set to 1ps-400ps, which is picoseconds, and 400ps-700ps is called picoseconds, and 700ps. However, the pulse time of picosecond laser is short, ranging from 300 PS to 450 PS, and the photoacoustic effect is 180 times that of traditional laser, with shorter pulse width and more wavelengths. We have entered the real era of picoseconds from 20 18, so picoseconds will damage subcutaneous tissue during surgery. When our skin is damaged, a lot of nutrients in the body will gather at the wound, so it will be supplemented in the early stage. Good result.
How often is the picosecond laser?
The interval of picosecond laser is usually 3~6 months, and it is more suitable for the natural growth of skin to do picosecond laser every six months. Picosecond can be done for a long time, but the interval should not be less than 6 months, because after each picosecond laser surgery, it will take at least two years from recovery to the growth of new tissue, and then whether it can be stably and continuously updated after the growth of new tissue, so it will bring a lot of harm to the skin again before the new tissue is completely grown and updated.
But there are also? A few picoseconds of laser may have a short interval due to the equipment, but if the interval is less than 2 months, you still need to be cautious and be responsible for yourself, because every picosecond, no matter how small the parameters are set, the subcutaneous tissue will be damaged, and the secondary growth and renewal of subcutaneous vesicles will take at least half a year. Continuous use combined with "Tight Beauty" for three months can completely restore new skin tissue. At this time, picosecond laser can be done in half a year.
What are the hazards:
The principle of picosecond laser mentioned above is to damage and destroy skin tissue, so the energy sweeps the skin epidermis, but this does not mean zero trauma. If the new tissue does not recover, picosecond laser will use powerful and fast energy to form light shock wave effect, and achieve the purpose of repairing damaged tissue by destroying deep skin. If the doctor does not master the energy, picosecond laser will destroy the stratum corneum first, and then the hyaluronic acid layer. . . . Then it will cause some undesirable phenomena, such as incomplete skin regeneration, chapped skin, pigmentation, leukoplakia, skin thermal injury, local redness, atrophic injury, uneven skin nutrition, subcutaneous nerve and skin collapse, dull and stiff skin color and so on.
Therefore, oral "firming beauty" nutrition can trigger the process of skin tissue formation, and can help the injured hyaluronic acid layer to generate bioactive peptide hyaluronic acid rare substances and other components to generate a living skin preservation layer. You can also beautify the wound in advance without soaking in water, which can give useful strength to the stratum corneum and reduce the danger brought by picoseconds. Hurt.
How long will it take to finish the picosecond laser to produce results? It usually takes at least a week to take effect, because the skin needs a basic recovery cycle. Many fairies are impatient. After finishing picosecond laser, I can't see the desired effect. I just feel that there are sesame-like black spots on my face, accompanied by slight red symptoms. I need someone to work hard, so I don't understand. It is normal for spots to appear after operation. Generally, the effect of picosecond laser can be seen when the skin recovers to a certain extent (at least 7- 14 days). If you take "Firming Beauty" because it can quickly and intensively repair skin tissue and its components, and at the same time prevent phospholipid Fenzi from being damaged by oxidation, the recovery time will be relatively shortened. However, we should also pay attention to hydrating and sun protection after operation, so that we can see the magic after picosecond laser as soon as possible.
Matters needing attention after operation
1, don't wash your face with water above 36 degrees for a week;
2. Don't go to high temperature environment (such as sauna, hot spring, yoga, etc.). ) in January, prevent exposure;
3. Do not eat spicy food or drink alcohol for a week;
4, three months after surgery, according to the doctor's advice 2 ~ 3 times a day oral once (tight beauty), according to the recovery situation, gradually reduced.
Don't touch alcohol, tobacco, soy sauce, spicy food and pickled products for one month.
6. Within a week, avoid using maintenance products such as fruit acid exfoliation.
7. It is forbidden to take oral collagen products before and after operation to avoid skin tissue imbalance.
8. After the wound scabs, it will subside in a week or so. After peeling off the scab skin, the skin is fragile. Make sure the skin is clean and hygienic, and do a good job of sun protection when going out to avoid blackening and pigment deposition.
The stain on the face is not formed in a day. It has a great relationship with our own endocrine (that is, growth from the inside out) and external factors, so any stain can not be removed in a short time, so freckle removal is a gradual process, which requires us to take good care of our skin. zy
