How Are Lasers Used in Cosmetic Clinics?

Lasers seem to be utilized for everything today - from 3D carvings to acne elimination. In order to understand how laser works on skin, acne and hair, it's first necessary to understand what laser treatment is, in the first place.

LASER is not actually a word - it's an acronym, just like UNICEF or UNESCO. Its full form is "Light Amplification by Stimulated Emission of Radiation". As the definition/full form itself states, laser beams are made by amplifying light waves, I.e. Increasing their amplitude. This amplification is done by passing light waves repeatedly to some medium which causes the waves to grow in amplitude. The medium is known as a "gain medium", and also the amplification usually uses mirrors or complete reflecting prisms. The final result is that a highly concentrated beam of energy jets out of a cavity in one of the reflecting surfaces, and is accompanied with a comparatively weaker ray of light that emerges as a result of constant and repeated reflections happening.

Cosmetic laser clinics utilize pulsed lasers. In pulsed laser, the beams of energy are emitted in pulses rather than a single, continuous and steady flow. This is useful for several reasons:

• It avoids burning sensitive skin
• It allows power to be concentrated on nodes that need it, like growing hair follicles or acne itself
• It helps the practitioner to control the duration and intensity of the beam better

LASER appliances used in cosmetic clinics are often tuned so that just a specific sort of tissue will react to them.

In baldness, the frequency of laser is such that melanin-heavy follicles will react better than the surrounding, light-coloured portions. Therefore, the laser beam is preferentially absorbed by the hair follicle, and its own mobile structure is changed permanently by the activity of the heat.

This means that only men and women who hair is considerably darker than their skin will be suitable candidates for laser hair removal. Light blondes and redheads are by default option from the laser depilation practice, while individuals with very dark skins might realize that a higher intensity of laser is required to remove their hair. Since dark skin tends to absorb laser beams equally as dark hair would do, it is quite likely that dark-skinned men and women will experience worse swelling as a result of laser hair removal compared to those with fairer skin.

To eliminate acne, the cells targeted by the laser are haemoglobin-rich cells. The haemoglobin in the cells absorbs the laser beam, and has heated up. This heat travels through to the sebaceous glands, which then slow down their activity radically. This way, acne can be prevented or minimized.

By tackling the problem at its source, laser cosmetic technology might offer non-invasive, almost painless solution for some of the most common cosmetic problems.
