Light Amplification by Stimulated Emission of Radiation (laser) is an acronym for Light Amplification by Stimulated Emission of Radiation. Without getting too technical, this simply means that the light source is directed through a very intense beam and is normally coherent, which means that it is reduced to a very specific wavelength of the light spectrum and is controlled to “vibrate” in just one plane. Some laser light can be observed with the naked eye, while others are in a spectrum that cannot be seen.Check out West Dermatology Hillcrest
So, where and how does this focused light technology fit into the field of dermatology, especially cosmetic dermatology? When applied to the skin, all lasers, regardless of type or wavelength, cause some kind of localised heating. This epidermal or dermal heating effect is used by a professional laser dermatologist to obtain a desired result. Some procedures are designed to simply burn away a small portion of the skin layer, while others are designed to cause some heating and mild burning of the skin layers with the purpose of causing healing, which results in new skin growth and a tightening effect. Lasers are also used to erase tattoos and scars, as well as to burn away unwanted growths like tumours or moles. The following are some of the most popular dermatological lasers and their applications. Each laser has a unique wavelength of light, as well as a variety of beam focus and pulsing options, as well as a range of intensities that range from minor heating to major burning. A successful laser outcome is dependent on the laser dermatologist’s expertise, as the highly qualified physician would know how to administer the correct laser at the right intensity to achieve the desired result.
1450 nm diode Laser: This is a very powerful deep penetrating laser for treating acne and wrinkles. After surgery, there is usually no need for recovery time. Even the most persistent cystic acne on the face, back, and chest can be cleared with the 1450 diode. This wavelength can also help with older and more severe acne scars.
CO2 High Intensity Super Pulse Laser: This is an effective laser that is commonly used to remove skin tumours and cancer.
The CO2 Silktouch Laser is a more efficient resurfacing laser that is commonly used to treat extreme wrinkles.
Erbium 294 Yag Laser: This is a resurfacing device that heals quickly and is used to treat wrinkles, burns, and tumours. Microerbium is a modern Erbium version designed for fractional resurfacing with no downtime.
Fractionated CO2 Laser: This is a newer CO2 laser that is designed to remove acne marks, wrinkles, surgical, and trauma scars.
Long Pulse Alexandrite Laser: This laser is most often used to remove hair from people with olive complexions.
This version of the laser is most commonly used for vascular lesions, stretch marks, scar revision, skin rejuvenation, acne treatments, and acne scars.
Long Pulse Ruby Laser: This device is most often used to remove hair from people with fair skin.
Long Pulse Yag Laser: This device is used to remove excess hair from dark-skinned people, as well as leg veins and tighten the skin in general. Fine hair can also be removed with this method.
