Q-Switch Laser describes a specific type of pulse; it is not a single device or wavelength and requires pigment evaluation.
What does Q-switch mean?
Q-switch is the working method that allows laser energy to be delivered in very short pulses; it is not a single device or a single wavelength. Different Q-switch lasers can target different pigments. The model of the device and the authorized area of use must also be verified.
Why is the diagnosis of pigment important?
Sunspot, melasma, post-inflammatory hyperpigmentation and pigmentary lesions are not the same. Laser should not be applied without a diagnosis of a new, changing or irregular formation. The source and depth of the pigment affect the result and risk.
Skin tone and test approach
Skin tone, recent tanning, recent sun exposure and previous color changes are evaluated. In dark skin tones, the risk of unwanted darkening or lightening may require more careful planning. In some cases, a small test area may be considered.
Treatment and safety
Protective eyewear, appropriate parameters and a trained practitioner are essential safety measures. Discomfort, temporary redness, swelling, crusting or darkening may occur. Blistering, increasing pain or an unexpected color change requires medical assessment.
Melasma and recurrence
Q-switch laser is not the first option in melasma. Although some studies report benefits, there is a risk of recurrence, post-inflammatory darkening and mottled opening. Sun protection and topical care remain important in most plans.
The difference with other methods
Pigmentation Treatment, Cosmelan & Dermamelan and BBL broadband light It is not the same technology. This page does not also mean that tattoo removal service is offered; the target and device are clarified during the examination.
Related Treatments
Assessment for a pigment-targeting laser does not require the same plan as light-based treatment, a peel or post-acne color change.
Pigmentation Treatment
Pigmentation Treatment prioritizes diagnosis and triggers of color change before considering laser treatment.
BBL Laser
Unlike a laser, BBL uses broadband light to address visible pigment or vascular redness.
The pulse pattern is not a diagnosis
The term "Q-switch" alone does not explain what the target is, which wavelength the device uses, or its personal suitability.
Pigment safety
Skin tone and the nature of the target are important in evaluating the risk of darkening or lightening.
- Evaluation of the type and depth of the pigment
- Including information about tanning and skin tone in planning
- Discussion of care to avoid irritation and protect from the sun
This page does not offer personal laser protocol or tattoo removal service.
Frequently asked questions about Q-Switch laser
Technology, pigment diagnosis, skin tone, melasma, eye protection and risk of color change.
No. It is a method that produces very short pulses; wavelength and device characteristics may vary.
No. The diagnosis of the lesion, pigment depth, skin tone and risks are evaluated.
No. There is a risk of recurrence and color change; a comprehensive plan is needed.
The risk of post-inflammatory darkening or lightening may increase; individualized parameter selection is needed.
No. Technology can also be used in tattooing; this page does not claim that this service is offered in the clinic.
Yes. Protective glasses suitable for wavelength are necessary for the patient and the practitioner.
The number varies according to pigment type, device, skin tone and individual response; a fixed number cannot be given.
