In a recent article, we spoke about the major differences between Q-Switch Lasers and Pico Lasers. (Read the blog here- Q-Switch Lasers VS Pico Lasers).

In today’s article, we will help to educate you further on Q-Switch Lasers and about the various benefits of the same.

About Q Switch Lasers

Q-Switch Laser is a type of non-ablative Laser that tends to release Laser beams in pulses per nanosecond, typically around 3-7 nanoseconds in length. The Laser beam that is originally produced is directed onto a polarizer, known as “Quality Switch”, hence the name Q-Switch. The beam that is released after passing through the polarizer gains much momentum and travels 6 times faster, which is the nanosecond domain. The speed of 10 to the power of 3 is amplified to 10 to the power of 9. This Laser beam of nanosecond speed, when directed onto the skin, tend to destroy the overproduced pigments into much smaller particles. These particles are then absorbed by the body and released by the immune system over time. It is commonly used to treat various pigmentary disorders such as post-inflammatory hyperpigmentation, melasma, acquired bilateral nevus of Ota-like macules and other epidermal or dermal pigmentation with minimal downtime. It is also ideal for tattoo removal.

With the advancement of science and technology, several varieties of Q-Switch Lasers are now available in the market in today`s time– ranging from Ruby (694 nm), Alexandrite (755 nm), or NdYAG with dual-frequency (532 nm and 1064 nm).

The Q-switched Nd: YAG Laser has two wavelengths – a longer wavelength of 1064 nm and a shorter wavelength of 532 nm. The longer wavelength of 1064 nm is ideal for dermal lesions due to its deeper penetration and poor absorption in epidermal melanin, while the 532 nm wavelength is ideal for epidermal pigmented lesions such as freckles &lentiges.

The NdYAGLaser beam specifically targets melanosomes in melanocytes, keratinocytes, and melanophages, at the epidermal and dermal depths, The Laser’s ultra-short pulse width (in nanoseconds), and adjustable spot size are key factors that allow effective targeting of pigment cells. Depth of penetration and selectivity are functions of the wavelength of a Laser.

The principal Laser-skin interaction observed in dermal melanocytosis by Q-switched Nd: YAG Laser treatment is based on photothermal, and photomechanical interactions induced by selective photothermolysis. The 1,064 nm Q-switched Nd: YAG Laser can cause dermal and epidermal melanosome rupture and destruction of dermal melanophages.

Do’s &Donts During Q Switch Laser Treatment

Treating pigmentary disorders especially in dark skin requires some precautions in order to get the best results, such as:

  • Strict sun-protective clothing and use of broad-spectrum sunscreens of SPF at least 30 prior to starting Laser treatment and throughout the course of Laser treatment.

  • Proper priming with skin-lightening agents such as hydroquinone, kojic acid, and/or other non-hydroquinone skin lightening agents, at least 2 to 3 weeks prior to the initiation of Laser treatment.

  •  Performing all the required tests prior to the Laser treatment procedure.

  •  Individualizing the various treatment parameters based on the patient`s requirements and medical conditions.

  •  Use of a Laser with a “top-hat” beam profile, large spot size, and lower fluences in darker skin types.

  •  Avoid stacking and too much overlap while treating.

  •  Cool the treated area with a postoperative ice pack for a few minutes.

  •  Application of emollients and a steroid ointment for 3 to 5 days (if blistering or crusting are anticipated).

Risk And Benefits of Q Switch Laser Treatment

Q Switch Laser treatments are relatively safe if performed by a trained or certified Aesthetic practitioners. The Aesthetic practitioner need to be well trained in terms of the principle of Laser, types of Lasers, Laser techniques, depth of Laser penetration, and Laser-tissue interaction so that they can properly administer the Laser treatment

However, in the wrong hands, complications can occur. Complications of Laser treatment include thermal burns which can be so intense to a point it may cause discoloration of the skin, scarring, infection, reactivation of herpes simplex infections, and even facial disfigurement.
