How much do you know about Picosecond laser?

Picosecond laser is the time that light hits the skin and stays in the skin - picosecond level. In academic terms, it is the pulse duration (pulse width) of light emission.

Because laser beauty is based on selective photothermal action to achieve the purpose of treatment: it only affects the target tissue (melanin), without causing obvious damage to other intact skin tissues.

Therefore, the shorter the pulse width (the faster the speed), the less light energy will diffuse to the surrounding intact tissue, and the more the energy will be concentrated on the melanin, the stronger the effect on the melanin, and the less damage to the surrounding intact tissue.

How fast can a picosecond go?


Various types of spots (freckles, chloasma, sun spots, age spots), birthmarks (coffee spots, nevus of Ohta, brown-green nevus), tattoos, acne marks, acne scars, wrinkles)

Traditional Q-Switched laser VS picosecond laser

Q-switched laser is generally used to remove freckles, birthmarks, tattoos, and acne marks. Its pulse width is at the nanosecond level, while the speed of picosecond laser is much higher than that of traditional Q-switched laser.

Comparison of shattering melanin particles

If the pigment particles deposited in the body are compared to rocks, traditional lasers can break rocks into the size of pebbles, while picosecond lasers can break them into dust.

Because the picosecond laser is fast, its blasting ability is stronger, the blasting is finer, the tissue absorption is better, and the curative effect is better, so it can make pigmented skin lesions produce stronger results in a shorter number of treatments. Efficacy.
