With the advancement of technology and the continuous improvement of people's pursuit of beauty, laser beauty technology is becoming increasingly mature. Among them, picosecond ND-YAG laser, as a new type of laser equipment that has emerged in recent years, has quickly become a star product in the field of skin beauty with its excellent freckle removal effect and safety. This article will take you on a deep understanding of the principle, advantages, and application areas of picosecond ND-YAG lasers, uncovering the scientific mysteries behind their miraculous effects.
Picosecond ND-YAG laser: perfect combination of speed and energy
Picosecond ND-YAG laser, as the name suggests, is an ND-YAG laser device that emits pulses with a pulse width of picoseconds (1 picosecond=10 ⁻¹ ² seconds). Compared with traditional nanosecond lasers, picosecond lasers have shorter pulse widths, which means they can transfer energy to the target tissue in a shorter amount of time, producing stronger optomechanical effects.
1. Working principle:
The working principle of picosecond ND-YAG laser is based on the principle of selective photothermal action. The laser emits laser light of a specific wavelength, which can be selectively absorbed by pigment particles in the skin, such as melanin and tattoo ink. After absorbing laser energy, pigment particles quickly heat up, producing a optomechanical effect that breaks them into smaller particles, which are then excreted from the body through the body's own lymphatic metabolic system, thereby achieving the effect of removing pigmentation, whitening and softening the skin.
2. Core advantages:
Shorter pulse width: Picosecond level pulse width means that laser energy is released in a very short period of time, producing stronger optomechanical effects that can more effectively crush pigment particles while reducing thermal damage to surrounding tissues, making the treatment process safer and more comfortable.
Higher peak power: The peak power of picosecond laser is hundreds of times that of traditional nanosecond laser, which can more effectively destroy pigment particles, with fewer treatment times and more significant effects.
Wide applicability:Picosecond ND-YAG laser can emit multiple wavelengths of laser, such as 1064nm, 532nm, 755nm, etc., which can provide precise treatment for pigmentation problems of different colors and depths.
Shorter recovery period:Due to the smaller thermal damage caused by picosecond laser to surrounding tissues, the recovery period after treatment is shorter, usually only 1-2 days to restore normal life.
Application areas of picosecond ND-YAG laser:
Picosecond ND-YAG laser, with its excellent performance, has a wide range of applications in the field of skin beauty, mainly including the following aspects:
1. Treatment of pigmentary skin diseases:
Skin pigmentation such as freckles, sunspots, and age spots: Picosecond laser can accurately target the pigment particles in the epidermal layer, breaking them down and eliminating them, effectively improving uneven skin tone, fading pigmentation spots, and brightening skin tone.
Skin pigmentation such as melasma, Ota nevus, and coffee spots: Picosecond laser can penetrate the epidermis and act on pigment particles in the dermis layer, effectively improving stubborn pigmentation and restoring fair and translucent skin.
Tattoo removal: Picosecond laser can effectively shatter tattoo ink particles and expel them from the body, achieving the effect of fading or even completely removing tattoos.
2. Skin rejuvenation treatment:
Improving fine lines and wrinkles: Picosecond laser can stimulate the regeneration of collagen in the skin, enhance skin elasticity, improve fine lines and wrinkles, and achieve the effect of firming the skin and delaying aging.
Shrinking pores and improving skin quality: Picosecond laser can promote skin metabolism, improve problems such as enlarged pores and rough skin, making the skin more delicate and smooth.
3. Other applications:
Treatment of acne and acne scars:Picosecond laser can inhibit sebaceous gland secretion, kill Propionibacterium acnes, improve acne symptoms, and fade acne scars, restoring skin health.
Treatment of scars:Picosecond laser can stimulate collagen regeneration, improve scar tissue, fade scar color, and make scars smoother and more flat.
What should be noted when choosing a picosecond ND-YAG laser
Choose a legitimate medical institution: Picosecond laser treatment belongs to medical beauty projects, and qualified medical institutions should be selected for treatment to ensure safety and effectiveness.
Choose an experienced doctor:The doctor's level of operation directly affects the treatment effect. Experienced doctors should be selected for treatment, and personalized treatment plans should be developed according to their own situation.
Proper preoperative and postoperative care:Avoid direct sunlight exposure before surgery, pay attention to sun protection and moisturizing after surgery, avoid using irritating cosmetics, and promote skin recovery.
As a cutting-edge technology in the field of skin beauty, picosecond ND-YAG laser has brought good news to many beauty enthusiasts with its excellent freckle removal effect, safety, and wide applicability. I believe that with the continuous advancement of technology, picosecond ND-YAG lasers will play a greater role in the field of skin beauty, helping more people achieve their beauty dreams and shine with confidence.
