A picosecond laser is a type of laser that emits extremely short pulses of light, on the order of picoseconds (trillionths of a second). These lasers are being used for advanced tattoo removal because they can break up the ink particles in tattoos more effectively than traditional nanosecond lasers.
The shorter pulse duration of a pico laser allows for less heat to be generated in the surrounding tissue, which can reduce the risk of scarring and other side effects. Additionally, picosecond lasers can target specific colors of tattoo ink more effectively, making them particularly useful for removing multi-colored tattoos. However, picosecond laser treatment may require more sessions than traditional laser tattoo removal.
Indications of pico second laser
- Picosecond lasers are mainly used for tattoo removal, but can also be used for other skin conditions such as pigmented lesions (e.g. age spots, sun spots, freckles) and acne scarring.
- Tattoo removal: 皮秒激光 are particularly effective for removing tattoos with bright, vibrant colors, as well as for removing tattoos that were previously resistant to traditional laser tattoo removal methods.
- Pigmented Lesions: Picosecond lasers can also be used to remove pigmented lesions, such as age spots, sun spots, and freckles. These Discovery Pico lasers can target the melanin in the pigmented cells, breaking it up and causing it to be absorbed and eliminated by the body.
- Acne scarring: Picosecond laser is also used to improve the appearance of acne scars by stimulating collagen production and remodeling the skin.
It is important to note that individual results may vary and a consultation with a licensed skin specialist is recommended to determine whether picosecond laser treatment is appropriate for your specific condition and goals.
Contradictions of picosecond laser
There are certain conditions or circumstances that may make a person unsuitable for picosecond laser treatment. Some of the main contraindications include:
- Active skin infections or open wounds: Picosecond laser treatment should not be performed on skin that is infected or has open wounds, as it can increase the risk of complications.
- Tanned or sunburned skin: Tan or sunburned skin can make the laser treatment less effective and increase the risk of side effects such as hyperpigmentation or scarring. It is recommended to wait until the tan or sunburn has faded before undergoing picosecond laser treatment.
- Active herpes simplex: If you have active herpes simplex (cold sores), it is contraindicated to perform picosecond laser treatment, as it can trigger an outbreak.
- Active acne: People with active acne should avoid laser treatment as it can cause flare-ups and lead to scarring.
- Pregnant or breastfeeding: Pregnant or breastfeeding women should not undergo picosecond laser treatment, as the safety of the procedure during pregnancy or breastfeeding has not been established.
- Certain medications: People who are taking certain medications such as isotretinoin (Accutane) or blood thinners should not undergo picosecond laser treatment, as they can increase the risk of side effects.
It is important to inform your skin specialist about any of these conditions you may have to avoid any complications or side effects.
