1.What is a Q-switched laser?
In short: Q Switched Nd Yag laser is a technology that compresses the laser pulse width and increases the instantaneous peak power output of the laser.
It can compress the laser to a nanosecond pulse, and release a certain amount of laser energy in a short period of time, causing a “small explosion” in the skin’s melanocytes under a microscopic environment, breaking the melanin, and then playing a role in tattoo removal and treatment of pigmentation problems.
Using Q-switched technology and the principle of “acoustic pressure mechanical explosion“, the pigment target tissue cells in the skin are exploded and disintegrated; part of the scab falls off, and part of it is absorbed and metabolized by the residues destroyed by lymph, macrophages, etc., to achieve the purpose of removing pigments.
After absorbing the high energy of the Q-switched laser in an instant, the pigment particles quickly vaporize, expand, and rupture to form smaller pigment particles. In the subsequent inflammatory reaction, the small pigment particles are engulfed by macrophages in the body.
2. The current Q-switched lasers include the following wavelengths:
Q-switched Nd: YAG1064/532nm, Q-switched ruby laser 694nm, Q-switched 755nm. Among them, 1064nm and 532nm are the most commonly used wavelengths.
3. The treatment range of Q Switched Nd Yag laser machine.
3.1 Inflammatory pigmentation:
Age spots, sun spots, melasma, PIH (inflammatory pigmentation), brown-blue nevus.
3.2 Genetic pigmentation:
Ota nevus, brown-blue nevus, freckle-like nevus, coffee spots, freckles.
3.3 Tattoo removal, exogenous pigmentation treatment.
Regarding the energy and parameter settings during treatment, due to the different causes, time, and symptoms of different pigmentary diseases, the energy, parameters, and energy density required to be set are also different. This, to a certain extent, greatly tests the operator’s skills.
However, due to the different power and energy of different devices, it is difficult to determine the exact energy and parameters required by different devices. The treatment still needs to be based on the clinical endpoint response of the treatment.
In our LITONLASER’s “Technology Beauty Core Technology Training Textbook“, we have detailed the energy within the safe range, how to set the parameters, and the most important clinical endpoint response of the treatment. You are welcome to refer to our textbook as a reference book for daily operations.

4. Treatment and repair time of Q-switched laser.
Due to individual differences in the size, type, depth, color of melanin particles of different pigment diseases, as well as personal skin color, metabolic rate, age, etc., the time for melanin particles to disappear after laser treatment is also different to a certain extent. Under normal circumstances, the time for melanin to disappear is 3-6 months.
The lighter the lesion and the younger the age, the better the treatment effect and the shorter the course of treatment. Therefore, if there is a problem with pigment disease, it is recommended to treat it as soon as possible, choose a regular medical institution and a professional physician, and Q-switched beauty equipment with stable energy.
5. Examples of repair products required after Q-switched laser treatment.
5.1 Use beauty products with simple ingredients, only containing collagen and water, which can quickly fade redness. Then use collagen gel as a support and barrier for damaged skin.
5.2 Secondly, use peptide repair essence to stimulate damaged skin to repair and regenerate quickly.
5.3 Use licorice liquid to play an anti-inflammatory and anti-allergic role.
5.4 Use tranexamic acid essence, L-vitamin C, astaxanthin, etc. to inhibit the deposition of melanin, block the transfer of melanin to surface cells, and play an anti-inflammatory role.
5.5 Use peptide repair lotion, hyaluronic acid stock solution, ceramide spray to enhance moisturizing and lock water, maintain the moist environment of the skin, and then pay special attention to sun protection.
6. Choice of Q Switched Nd Yag laser beauty machine.
As a beauty equipment manufacturer with 20 years of experience, LITONLASER has rich experience and has developed and sold many Q-switched laser tattoo removal equipment. There are many models, three portable models, one of which is the latest experience this year, 2000mj energy, single lamp and double bar Q-switched laser, which has obvious tattoo removal effect and can be applied to tattoos of most colors.
There are also two vertical Q-switched machines, which are often used in hospitals and clinics that require higher energy. High energy is not only for tattoo removal, but also for the treatment of skin problems such as pigmentation and spots.
