Skin brightening laser

What are the differences between a picosecond laser and a Q-switched laser?

Posted by

Laser treatments for skin brightening, reducing melasma, freckles, and dark spots are very popular today because of their ability to show quick results. Current technologies are constantly improving the removal of melasma, freckles, and dark spots.

Many people are familiar with Q-switched Laser, the original technology used to remove tattoos, fade freckles, age spots, and dark spots. And recently, in the last few years, new technology has emerged... Picosecond Laser Developed from the Q-switched laser, it offers a wider range of skin problems, fewer side effects, and faster treatment time for visible results.

Let's delve deeper into the advanced differences between these two lasers.

What's the difference?

What is a picosecond laser?

Picosecond lasers are an advanced version of the original Q-switched laser technology, which emitted light energy at nanosecond speeds—one unit per billionth of a second. This technology has been developed to be a thousand times faster, allowing picoseconds to emit light energy at picosecond levels—one unit per trillionth of a second.

How is releasing light energy faster better?

Because picosecond lasers can deliver light energy much faster than before—at the level of one unit per trillionth of a second—this speed doesn't allow enough time for the skin to accumulate heat and burn like with older technologies. Therefore, side effects such as irritation, burning, redness, or scarring are virtually nonexistent.

Conversely, this speed greatly enhances the machine's performance. The high-speed emission of light creates a pressure wave, which compresses the energy to a higher level, creating a wave that instantly breaks down melanin pigments into tiny particles. This breakdown is much more precise than with conventional energy methods. Furthermore, the energy is focused on breaking down all types of pigments. The body then naturally eliminates them, something that traditional laser devices cannot do.

Picosecond Laser VS. Q-Switched Laser

Let's summarize the differences between them. Picosecond Laser Q-Switched Laser Okay.

  • Picosecond Laser It breaks down the pigments more finely. Q-Switched Laser This results in shorter treatment times and faster results.
  • Picosecond Laser It doesn't cause skin burns, doesn't build up heat on the skin surface, and you won't feel any pain, or will feel less pain during the procedure. Q-Switched Laser very
  • Picosecond Laser The skin will need less time to recover after the procedure. Q-Switched Laser 
  • Picosecond Laser It has interchangeable power heads, allowing for more specific focus on individual problems. Q-Switched Laser
  • Picosecond Laser It helps to make the skin smoother, brighter, reduce wrinkles, and tighten pores because it can stimulate collagen production in the skin, unlike... Q-Switched Laser That will help solely with removing pigment.

NU PICO is an innovative Picosecond Laser that utilizes a special firing technique developed by the expert medical team at Romrawin Clinic. Based on extensive experience from numerous cases, they have created the best technique to effectively address skin pigmentation disorders such as melasma, freckles, dark spots, and even tattoos. It helps brighten the skin, smooth the texture, reduce pore size, and minimize acne scars.

Advantages of NU PICO

  • No heat buildup, no risk of sunburn: Picosecond Laser technology involves no heat during treatment. The energy of the Picosecond Laser is released in a very short burst and compressed into an energy wave that instantly breaks down pigment particles into fine ones without causing heat buildup. This minimizes the risk of burns and makes it suitable for Asian skin, including those with darker skin tones.
  • See results faster than before: When pigments are broken down more rapidly and finely, the body can more easily eliminate these fine pigment fragments. This helps freckles, age spots, dark spots, or even tattoos fade faster, reducing the number of treatment sessions required.
  • Treats freckles, shallow and deep pigmentation, and tattoos of all colors: Picosecond laser technology offers multiple wavelengths, allowing for comprehensive treatment of both superficial and deep pigmentation, and can address all colors of tattoos, even difficult-to-treat colors like yellow and orange.
  • Don't be afraid of getting hurt: This is a minimally invasive innovation, especially when used in skin rejuvenation programs to brighten and smooth the skin. It can be performed without numbing cream, making it ideal for patients who are afraid of pain. It causes little to no scabbing after treatment and requires no recovery time.

Steps for creating a NU PICO program.

  • We begin by cleaning the skin. In cases where topical anesthesia is required, a numbing cream will be applied and left on for approximately 45 minutes.
  • During laser treatment, you'll feel a slight stinging sensation on your skin. The intensity of the sensation depends on the program being performed. For skin brightening and dark spot reduction, you'll feel almost nothing. However, for tattoo removal, you might feel more sensation in areas with a high concentration of pigment. This procedure takes approximately 30 minutes.
  • The recommended number of sessions for noticeable results varies from person to person, depending on the skin problem, pigmentation, size of the tattoo, depth, and color. Generally, 3-4 treatments are needed, spaced 2-4 weeks apart. However, for tattoo removal, the interval may need to be 4-8 weeks.
  • After laser treatment, avoid strong sun exposure for the first 2-4 weeks. Apply moisturizing cream and use sunscreen with an SPF of 30 or higher regularly.
  • If it itches or scabs form, do not pick or scratch them, as the scabs will fall off on their own within 7 days.
  • Avoid hot baths, steam rooms, or saunas for 1-2 days after laser treatment, and avoid using topical creams containing retinol or fruit acids for 2-3 days after laser treatment.
