Freckle is a very common brown spot, also called epidermal spot. Is determined by genes. Generally speaking, 10 begins to appear at the age of 5. Of course, some people appear later, such as adolescence, or even after going to college in their twenties. Whether it's genetic.

But some factors of the day after tomorrow will determine whether it will be serious, such as exposure, such as changes in hormone levels, such as pregnancy, taking some birth control pills, which may make your spots darker or more.

These things will affect our appearance when they grow on our faces, and everyone will care about how to get rid of them. Traditionally, such as liquid medicine, freezing, etc. In the era of laser, they are an effective method, but these methods first require the operator to have very high experience.

Second, these preparations are unstable, and the operating effects of different batches and different people are quite different. Thirdly, these treatments are particularly easy to sink, or form some new spots or discoloration, which is easy to cause complications.

Therefore, these treatments have been gradually abandoned by the majority of medical institutions. If it is to pursue the effect, you can choose laser. After laser treatment, there are certain requirements for water avoidance and makeup, but it is better than photon rejuvenation for a course of treatment.

There are two kinds of lasers at present. First, the traditional mainstream laser is Q-switched laser with nanosecond pulse width and good therapeutic effect. At present, the latest laser is the so-called picosecond laser with narrow pulse width, that is to say, the laser with pulse width of picosecond level. This kind of laser has stronger pigment blasting ability, relatively less energy, relatively lower pain during treatment and better treatment effect. Of course, picosecond treatment of freckles is far from as magical as some organizations advertise.
