The effect of some pigmentation removal surgeries on the internet is very exciting, however, you should not do it on a whim. You should first figure out these things, and then “prescribe” the right medicine.
Types of spots: Generally speaking, common spots are divided into four types, such as freckles, chloasma, age spots and brownish nevus.
Causes of spots: The formation of spots is divided into congenital and acquired ones. Congenital is generally genetic, and the biggest reason for the formation of spots is photodamage, which is often referred to as ultraviolet light. However, we can’t say that all the spots are caused by UV rays, because there are many factors that trigger different spots.
Freckles, cyanotic nevus on cheek
Genetic genes + ultraviolet light mainly, mainly related to heredity, usually with family history, and will increase slowly after sun exposure.
Melasma
Endocrine + UV + genetic (less). It is also called “butterfly spot” and “liver spot”, which is typical of “fast coming and fast going”. It may be aggravated by more sunlight today and tomorrow, or it may fade away automatically.
Age spots
Skin damage + ultraviolet light is the main cause, mostly seen in the elderly.
How can laser remove spots?
Laser is a monochromatic light with certain penetrating power, which can produce powerful and highly concentrated radiation energy in an instant, acting on human tissues and generating high heat locally to vaporize and break up pigments inside the skin, and then discharging the broken pigment particles out of the body through skin metabolism, thus achieving the purpose of removing or destroying the target tissues. Various pulsed lasers of different wavelengths can treat various vascular skin diseases and pigmentation. Since the laser of specific wavelengths can reach the pigmented tissue through the epidermis and dermis, only the pigment particles are used, and the epidermis of the skin is basically not damaged, thus achieving the effect of small damage or even no obvious damage to the epidermis, not easy to leave scars, precise efficacy and little pain. Simply put, different color pigments can absorb specific wavelengths of laser light, which can be directed and struck precisely, and only the pigment will be injured but not the skin.
Can laser pigmentation removal recur?
Lasers have become one of the most important treatments for pigmentation, but any cosmetic technology has its limitations, and so does the laser. It can only remove the existing pigment, but it cannot prevent the pigment from growing back.
Pigmentation is not caused by toxins in the skin, nor is it caused by toxins in the liver, kidneys and other internal organs. The skin contains a large number of pigment cells, which are very important for the skin to resist external damage such as UV rays. When certain external stimuli (UV, sunlight, inflammation, etc.) are sensed by the pigment cells, they are activated to prevent these stimuli, which is manifested as enhanced pigment function. Although these pigment cells serve a protective function for the skin, if they become overly sensitive and become uncontrollably pigmented, they can make our skin appear pigmented.
There are many reasons for the enhanced pigment cell function, the main ones are
UV rays, which is a very important cause for the formation and aggravation of pigmentation spots such as melasma. UV rays can directly activate pigment cells and produce excessive pigment.
Estrogenic effects, some discolorations, such as melasma, are related to estrogen. First, it rarely develops in men; second, pregnancy and oral contraceptives may induce the production of pigmentation. Elevated levels of estrogen, progesterone or related hormones can increase melanocyte activity, thus making pigmentation arise and deepen.
Bad lifestyle habits such as stress, partial eating and lack of sleep can also increase melanin. People with erratic sleep schedule and poor metabolic rate of skin can affect the production of melanin particles.
Genetic, chromosomal inheritance is the main cause of facial pigmentation. It mostly starts from children around 5 years old, mostly female, heavy in spring and summer, light in autumn and winter. Light brown to yellowish brown pinpoint to rice-grain-sized spots, symmetrically distributed on the face (especially on the nose).
There are many reasons for the formation of pigmentation spots, but the reasons are skin care and internal body reasons. Although laser treatment has good effect or even complete elimination, but the inappropriate care of skin after treatment, such as whether to consolidate treatment, sunscreen, improve diet, etc. will affect whether the pigmentation spots recur after treatment.
How to avoid recurrence of pigmentation?
After the scabs fall off, you should apply sunscreen (SPF15 or above) and also indoors to prevent the damage of UVA/UVB rays. Because the treated area is very sensitive to sunlight, you should avoid sunlight for 3 months to 6 months, and try to use sunscreen or umbrella to improve the treatment effect.
For daily skin care, care should be taken not to use poor quality cosmetics and peeling, exfoliating and hormonal products after treatment. It is recommended to use medical skin care products.
For daily diet, eat more foods containing vitamins C and E or take vitamin C orally.
After suitable laser treatment and strict post-operative care, most patients will not have the problem of pigmentation again, but even if the pigmentation appears again for various reasons, there is no need to worry excessively, as long as the laser treatment is carried out again, there will still be effects.
For each kind of spots, the treatment plan and course of treatment are different, but generally speaking, most of the spots can be well lightened after treatment. The specific treatment plan can only be determined through the doctor’s interview. Whether it is freckles, brown nevus or even age spots, they can all be treated by means of picosecond laser, while for melasma, oral and topical medications are usually the main treatments, and if the effect is not good, subsequent treatment by picosecond laser can also be considered to get rid of them.
Picosecond laser pigmentation removal is a type of laser technology, which is a laser that emits pulses of picosecond duration (pulse width) per laser, allowing the skin tissue to be exposed to a high concentration of energy, which extensively and intensively stimulates the fibroblast response to produce collagen and elastic fibers. The effect of picosecond spot removal usually lasts about 1 to 2 years.

Who are not suitable for picosecond laser?
1、Scarred people are not suitable for picosecond laser pigmentationremoval: scarred people will easily cause facial skin growth scars after laser, which will affect the facial beauty. (https://www.sunhingtech.com/product-category/laser-machine/picolaser/)
2、People with high blood pressure and heart disease are not suitable for laser pigmentation removal in picosecond: As there will be a burst of stinging pain in laser pigmentation removal in picosecond, it may cause a rapid increase of blood pressure and heart discomfort due to the guest’s tension, which will cause danger.
3、Diabetic patients are not suitable to do picosecond laser spot removal: picosecond laser spot removal has to destroy the epidermis, and the skin of diabetic people heals very slowly, so it is not suitable to do picosecond laser spot removal.
4、 vitiligo do not do picosecond laser spot removal: itself has a pigment cell problem vitiligo people, not recommended to use picosecond laser stimulation facial epidermis, will aggravate the possibility of vitiligo spread.
5、Don’t do picosecond laser if there is an emergency: any treatment for freckles has to have a recovery process. After laser freckle removal, firstly, scabbing, scab removal, skin reddening and then darkening, such a whole process needs a period of time to recover, so if there is an emergency in the near future, such as meeting clients, participating in interviews, etc., it is not recommended to choose picosecond laser freckle removal immediately.
6、If you want to cure freckles, it is not recommended to choose picosecond laser to remove freckles: Picosecond laser to remove freckles can lighten most of them, but it is impossible to cure them completely, so it is recommended to choose other ways to remove freckles if you want to cure them.
