The picosecond laser is a revolutionary tool that has gained popularity in recent years due to its ability to effectively remove tattoos and rejuvenate the skin. This advanced technology has shown promising results in various clinical applications, including tattoo removal, pigmentary diseases, photoaging, and acne scars.
How Does Picosecond Laser Work?
------------------------------------
The picosecond laser uses a unique honeycomb pattern to redistribute and focus energy in the center of the lens, forming a high-energy area surrounded by low-energy areas. This stimulates the regeneration of dermal collagen fibers, leading to improved skin texture and reduced appearance of fine lines and wrinkles.
Clinical Applications of Picosecond Laser
------------------------------------------
1. Tattoo Removal
The picosecond laser is a safer and more effective new option for refractory tattoos. After irradiation, it produces finer particles through photomechanical action, which are easily phagocytized and cleared by macrophages, resulting in a higher pigment clearance rate.
2. Pigmentary Diseases
Picosecond laser has been gradually used in the treatment of pigmented diseases due to its good results in tattoo removal. It has the advantages of short treatment cycle and mild adverse reactions, making it an effective option for patients who are ineffective in nanosecond laser treatment.
3. Photoaging
The histopathological characteristics of skin photoaging include the degeneration and accumulation of elastic fibers in the dermal papilla and middle dermis, accompanied by reduced collagen synthesis and structural changes in the collagen fiber network. The picosecond laser can improve the treatment effect of photoaging, especially for patients who are ineffective in nanosecond laser treatment.
4. Acne Scars
The picosecond laser can effectively improve facial acne scars by stimulating the regeneration of dermal collagen fibers, increasing the density and length of dermal elastic fibers, and increasing the deposition of collagen III and mucin.
Frequently Asked Questions About Picosecond Laser
---------------------------------------------------
1. Will picoseconds make the skin thinner?
No, picoseconds will not make the skin thinner. In fact, it can increase the thickness of the skin, moving in the direction of youthfulness.
2. Will my skin become sensitive after picosecond treatment?
Under normal circumstances, skin will not become sensitive after doing picoseconds. However, if your skin is in the sensitive period, you must not do picoseconds, and you should pay special attention to skin care after having picoseconds.
3. Is picosecond a universal freckle removal tool?
No, picosecond is not a universal freckle removal tool. It is often used for various types of stain treatment and tattoo treatment, but it has limitations when it comes to brown spots.
4. Who is not suitable for picosecond surgery?
The following six types of people are not suitable for picosecond surgery:
* Beauty seekers with scarred physique
* People with allergies and photosensitive constitutions
* Pregnant women, patients with high blood pressure, heart disease, and abnormal blood coagulation
* People with skin infection
* People who have been exposed to the sun or will be exposed to the sun in the past 3-4 weeks
