In the pursuit of smooth skin, cutting-edge technology remains the most powerful assistant in meeting people's needs. Following the widespread application of ND:YAG lasers in the medical aesthetics field, a technology hailed as a "milestone in laser beauty"—the picosecond laser—is redefining the standards of pigmentation treatment and skin rejuvenation with its revolutionary efficacy. It's not merely a simple technological iteration, but a leap from the "photothermal effect" to the "photoshock wave effect." So, do you truly understand picosecond laser technology?
The core advantage of picosecond lasers lies in their ultra-short pulse width, which is in the picosecond range (one trillionth of a second).
Compared to traditional nanosecond lasers, it uses a "shockwave"-like mechanical effect to shatter pigment particles into "dust," making them easily metabolized and removed by the body.
Picosecond lasers offer significant advantages in treating pigmentation spots, tattoos, and improving skin texture, including better efficacy, fewer treatments, less thermal damage, and a shorter recovery period.
Picosecond laser refers to laser devices with a pulse width (i.e., the duration of each pulse) reaching the picosecond level (1 picosecond = 1 trillionth of a second). This ultra-high-speed emission method has fundamentally changed the way lasers interact with skin pigmentation, representing a major technological breakthrough in the field of laser cosmetic treatments. This technology utilizes photomechanical effects, rather than simple thermal effects, to break down pigmentation and tattoos, and stimulate collagen production, while minimizing damage to surrounding skin.
Because picosecond lasers are very fast and generate less heat, the pain is less, the risk of scarring is reduced, ensuring patient safety and a better experience. Furthermore, picosecond laser treatment requires almost no recovery time, allowing you to quickly return to your daily life and work. Therefore, picosecond laser treatment is particularly suitable for busy individuals who want to quickly and effectively resolve skin and pigmentation problems.
The high efficiency of picosecond laser treatment for skin problems and pigmentation issues primarily relies on the photoshock wave effect (also known as the photomechanical effect or photoacoustic effect).
Traditional Q-switched nanosecond lasers mainly rely on the photothermal effect, like cracking a large rock with a hammer, generating a large amount of heat energy in the process, which can easily damage surrounding skin tissue.
However, picosecond lasers, due to their extremely short pulse width, generate a powerful mechanical shock wave through an instantaneous burst of energy. This shock wave can precisely shatter melanin particles into finer dust particles. These dust-like pigment particles are more easily phagocytosed and metabolized by macrophages in the body, thus achieving higher removal efficiency and significantly reducing thermal damage to the skin, lowering the risk of post-treatment hyperpigmentation.
Furthermore, when used with special lenses (such as honeycomb lenses or focusing lenses), the energy of the picosecond laser can be focused and, without damaging the epidermis, produce the LIOB effect (laser-induced photolysis) in the deep layers of the skin, creating a cavitation tissue reaction. This micro-injury can effectively activate the skin's wound repair mechanism, stimulating the regeneration of collagen and elastin fibers, thereby achieving skin-rejuvenating effects such as smoothing acne, shrinking pores, and firming the skin.
Thanks to its precise wavelength and unique effects, picosecond lasers have a wide range of applications:
This is a core strength of picosecond lasers. It includes various epidermal pigmentation issues (freckles, sunspots, café au lait spots) and dermal pigmentation (nevus of Ota, zygomatic nevus). For refractory melasma, picosecond lasers can also serve as an effective adjunct treatment.
Picosecond lasers currently represent the "high standard" for tattoo removal. It effectively removes dark tattoos such as blue, black, and green, and also shows significant effects on colored tattoos such as red, yellow, and orange, which are difficult to remove with traditional lasers.
Through the LIOB effect generated by fractional lasers such as honeycomb lenses, it effectively stimulates collagen regeneration in the dermis, thereby improving pitted scars (acne pits) and enlarged pores left after acne.
Stimulating collagen regeneration can smooth fine lines, increase skin elasticity, brighten skin tone, and achieve overall facial rejuvenation.
Adequate pre-treatment preparation is essential for ensuring the safety and effectiveness of the treatment.
You need to communicate fully with your doctor to understand the general treatment process, expected results, and potential risks. The doctor will assess your skin condition to determine if you are suitable for treatment.
You need to inform your doctor about your health condition. Women who are trying to conceive, pregnant, or breastfeeding, as well as those with photosensitivity, immune system disorders, coagulation disorders, skin infections, or open wounds, are generally considered contraindicated.
Avoid sun exposure for 2-4 weeks before treatment. Avoid other laser or phototherapy treatments for 3 weeks before treatment. Discontinue the use of irritating or photosensitive products such as glycolic acid, retinoic acid, and high-concentration vitamin C for 1-2 weeks before treatment.
Thoroughly cleanse the treatment area. Do not wear makeup or use any skincare products to ensure clean skin and avoid affecting the treatment results.
Proper post-treatment care directly determines the final outcome and the incidence of complications. This step is crucial if you want to ensure the best treatment results.
Immediate Soothing: After treatment, the skin may experience temporary redness and heat. Apply cold compresses or ice packs immediately (approximately 15-30 minutes) to relieve discomfort and swelling.
Gentle Cleansing and Moisturizing: Within one week of treatment, gently cleanse with a gentle cleanser and lukewarm water. Strengthen moisturizing by using simple, fragrance-free, and preservative-free medical-grade repair products.
Strict Sun Protection: Post-treatment skin is extremely sensitive to ultraviolet rays, making this a critical period for preventing post-treatment hyperpigmentation. Strictly adhere to the principle of combining physical sun protection with the application of high-SPF sunscreen, reapplying every 2-3 hours.
Managing Scabs: If scabs appear at the treatment site (common in dark spots and tattoo treatments), allow them to fall off naturally (usually within 5-7 days). Do not pick or scratch, as this may cause scarring or pigmentation.
Avoid irritation: Within one week after the procedure, avoid using skincare products containing irritating ingredients such as alcohol, fruit acids, and salicylic acid. Also avoid saunas, hot springs, and strenuous exercise that causes excessive sweating.
