The acronym ‘Laser’ stands for light amplification by stimulated emission of radiation. A laser works by emitting a wavelength of high energy light, which when focused on a certain skin condition creates heat and destroys diseased cells.
Different types of lasers are available for various indications like hair reduction, scar remodeling, tattoo removal and so on.
A Q-switched Nd-yag laser has short pulse duration/high peak energy Q-switched pulses so quickly that they create a photo-acoustic effect within the pigment clusters. Hence it is used as a pigment removal laser
Tattoo ink and natural pigmentation like melanin absorb high energy waves.This effect breaks down the ink into much smaller particles that can be more easily removed by the body’s natural filtering system.
Conditions like freckles, cafe-au-lait spots, nevus of ota, melasma are common conditions treated by this laser.
Nonablative skin rejuvenation
The deep dermis is stimulated to produce natural collagen and other vital proteins that make up healthy, youthful skin. Painlessly done in less than 20 minutes, you’ll leave the office with only mild redness that will fade within a few hours. After 3-6 treatments, done at monthly intervals, wrinkles soften and skin gets toned.
Dark lips are a common cosmetic concern. Two to four sessions of Q-switched laser is an effective treatment for lip lightening.
It helps to clear out pigmented spots, bleaches the fine hairs and instantly removes tan giving a brighter and an even toned face. This is the most common indication for the q switched laser.
