Laser cosmetic and medical appplications

Lasers: If you’re contemplating laser surgery for a cosmetic operation, you’re likely to encounter a variety of different laser methods. While they all share certain characteristics, the consequences of various laser techniques vary. Then, let’s examine which lasers are most effective for treating common skin diseases.

Laser Treatment The acronym L-A-S-E-R (light amplification by stimulated emission of radiation) stands for light amplification by stimulated emission of radiation. A laser is a source of high-energy light with a single wavelength (one color of light) that can be precisely focused to transfer the light to a very tiny region in order to accomplish the desired effects.

Lasers: Ablative vs. Nonablative

Lasers used for cosmetic reasons are classified as ablative or nonablative.

While ablative lasers vaporize the injured skin’s top layers, non-ablative lasers penetrate deeper into the skin without removing or harming the top layers. As a result, you will have no downtime after a cosmetic operation that utilizes only nonablative laser technology.

How Lasers Operate

Lasers are monochromatic, which implies that they emit just one wavelength of light (color of light). Lasers perform aesthetic operations using a method called selective photothermolysis. This implies they control the frequency of light (photo) in order to generate heat (Thermo) in the region to be killed (lysis).

To do this, the laser beam’s wavelength must match the hue of the target, which might be brown patches, red burst capillaries, or another kind of skin problem.

Why Are There So Many Types?

There are several subcategories of lasers and hundreds of variants and brand names. The primary distinction between the various kinds of lasers is in their wavelength. Different wavelengths are used to treat various skin conditions. 1 As a result, your surgeon may propose a combination of many lasers to address all of your concerns.

Different types of cosmetic and medical applications

• Wrinkles & Fine Lines: To cure lines and wrinkles, a combination of skin resurfacing and skin tightening treatments may be employed, or both operations may be performed with a more aggressive ablative laser, such as a CO2 (carbon dioxide) or Erbium laser.
•  Additionally, the CO2 laser is often used to remove warts and skin tags, as well as to cut the skin during laser-assisted surgery. Pulsed dye lasers, as well as less severe non-laser light-based therapies such as intense pulsed light therapy (IPL) and light-emitting diode (LED) photo facials, have also shown some efficacy.
• Skin Tightening: The majority of cosmetic laser treatments achieve some amount of superficial skin tightening by inducing controlled damage to the skin, which stimulates collagen formation. CO2 is the laser of choice for more dramatic tightening outcomes. Additionally, there has been considerable success with non-laser, light-based therapies, such as Titan infrared devices and Thermage radiofrequency systems.
• Pigmented Lesions: The pulsed dye, Nd:YAG, and fractional CO2, as well as nonlaser, light-based therapies such as IPL, are the most often used for the treatment of pigmented lesions such as sunspots, age spots, melasma, and other types of hyperpigmentation.
• Precancerous Lesions: Almost all surgeons believe that cancerous lesions should be excised with a scalpel (during surgery, with a knife) to guarantee clean margins and thorough eradication. This gives a sample for a pathologist to examine in order to ascertain the specific nature of the lesion. However, by eradicating precancerous growths such as actinic keratoses (squamous cell skin tumours) before they become malignant, lasers are now frequently employed as a prophylactic strategy.
• Tattoos: Q-switched Nd:YAG lasers continue to be popular for tattoo removal.
• Laser Hair Removal’s effectiveness and safety are heavily reliant on the pigment existing in the patient’s skin and hair. Nd:YAG and diode are often used on darker-skinned patients, whereas IPL has been beneficial on lighter-skinned people.
• Acne Scars and Acne Scarring: The CO2 remains the gold standard for treating deeper acne scars, but more recent innovations such as the erbium:YAG, fractional laser, and various nonablative have shown significant effectiveness in treating superficial acne scarring. LED technology has been shown to be highly helpful in the treatment of aggressive acne.

Additional Cosmetic Applications Using Light

There are several light-based technological methods being employed in the area of cosmetic surgery today. While these operations are sometimes referred to as “laser” procedures, the instruments employed are not genuine. IPL, LED treatments, Titan, and similar infrared energy-based technologies, as well as radio-frequency-based procedures like Thermage, are among these technologies.
