Picosecond laser vs. Nanosecond laser

1. The impact of pulse width differences on the effect

- Picosecond laser: The pulse width is in the picosecond (one trillionth of a second) level, which is shorter than the nanosecond laser (one billionth of a second). It can act on pigment particles more quickly and accurately, causing almost no thermal damage to surrounding tissues. It is suitable for treating pigmentation, tattoo removal and other problems, with more significant effects and a shorter recovery period.

- Nanosecond laser: Due to the long pulse time, the energy transfer is relatively slow, which may cause more thermal effects during treatment, resulting in higher skin irritation or more obvious reactions (such as redness and swelling).

2. Treatment Feeling

- Picosecond laser: The treatment process usually feels less painful and the pain is less than that of nanosecond laser. Because the pulse time is short, the energy is released quickly and acts on the pigment particles immediately, reducing the impact on surrounding skin tissue.

- Nanosecond laser: Due to the relatively slow energy release, you may feel a strong stinging or burning sensation during treatment. You need to use anesthetic cream or ice compress appropriately according to different treatment areas to reduce discomfort.

3. Clinical effect

- Picosecond laser: The treatment effect is more significant, especially in removing spots, pigmentation, tattoos and improving skin texture. By breaking pigment particles into smaller particles, it can help the body metabolize and excrete pigments more efficiently, thereby achieving faster and more significant results. Picosecond laser also stimulates collagen regeneration in the skin, helping to improve skin firmness and smoothness.

- Nanosecond laser: Usually effective in treating some deeper pigment problems (such as dark tattoos, deep freckles), but due to its slower pulse time, it may cause some minor skin damage and recovery period Relatively long. Mild redness, swelling or scabbing may occur after treatment.

4. Indications for treatment

- Picosecond laser: suitable for treating a variety of skin problems, including spots, acne marks, age spots, tattoos, and improving the overall texture of the skin. It is also more suitable for darker or sensitive skin types.

- Nanosecond Laser: Although it can also achieve good results on pigment issues, it may be more advantageous when dealing with some darker pigment accumulations. It has more side effects than picosecond laser, has a longer recovery period, and is suitable for a relatively limited group of people.

5. Recovery Period

- Picosecond Laser: Due to the short pulse, the recovery period is relatively short. There may be slight redness, swelling or stinging after treatment, but this will subside quickly.

- Nanosecond Laser: Due to the strong thermal effect, the recovery period is usually longer. After treatment, scabs, redness, and swelling may appear, which will take a long time to repair.

6. Treatment Price

- Picosecond Laser: Picosecond laser treatment prices typically range from $300 to $1,500.

- Nanosecond laser: The price of nanosecond laser is generally between $100 and $800.
