Originally developed in 1960, lasers were soon introduced into medicine. Advances in the 1980s established a strong scientific foundation for their medical use and demonstrated their effectiveness across multiple fields. Since then, the use of lasers in dermatology and cosmetic procedures has expanded significantly.
What Is a Laser?
The word “laser” is an acronym for “Light Amplification by Stimulated Emission of Radiation.” In simple terms, a laser produces an intense, focused beam of light of a single wavelength.
This beam is generated using a specific material, known as the lasing medium, and is amplified through optical components. Different lasers are classified based on the material used, such as Nd:YAG (neodymium-doped yttrium aluminum garnet), KTP (potassium titanyl phosphate), and carbon dioxide lasers.
How Lasers Work in the Skin
When applied to the skin, laser energy travels until it is absorbed by specific target structures. Different tissues absorb different wavelengths of light, allowing for selective treatment of certain conditions without affecting surrounding tissue.
For example, KTP and pulsed dye lasers are primarily absorbed by blood and are used to treat vascular conditions. Carbon dioxide lasers are absorbed by water within tissues and are commonly used for skin resurfacing.
Common Applications of Laser Treatment
Lasers are used in a wide range of dermatologic and cosmetic procedures. Common applications include:
- Treatment of vascular conditions such as telangiectasias (broken capillaries), port-wine stains, and hemangiomas
- Treatment of pigmented lesions such as age spots
- Laser hair removal
- Tattoo removal
- Skin resurfacing for rejuvenation or scar treatment
Because each laser operates at a specific wavelength, no single device can treat every condition.
Individualized Treatment Approach
Laser treatments must be tailored to each individual patient. Factors such as skin tone, presence of suntan, lesion size, and treatment location all influence the choice of laser and treatment settings.
Selecting the appropriate laser and parameters is critical to achieving effective and safe results.
Experience and Expertise Matter
Dr. Alexander Berlin completed fellowship training in Procedural Dermatology, which included extensive training in laser surgery. He has over 18 years of experience in this field and has authored numerous journal articles, book chapters, and textbooks on laser procedures. He has also presented his work at professional conferences.
This level of experience is essential in selecting the appropriate technology and delivering optimal outcomes for each patient.
Frequently Asked Questions
Can one laser treat all skin conditions?
No. Each laser operates at a specific wavelength and targets particular structures in the skin. Different conditions require different types of lasers.
Are laser treatments safe?
When performed by an experienced physician and properly selected for the patient’s skin type and condition, laser treatments are generally safe and well tolerated.
Do laser treatments require downtime?
Downtime varies depending on the type of laser used. Some treatments have little to no downtime, while others may involve temporary redness, swelling, or peeling.
How many treatments are needed?
The number of treatments depends on the condition being treated and the type of laser used. Some conditions require multiple sessions for optimal results.
Laser treatments are highly individualized and depend on your specific skin concerns and goals. Schedule a consultation to determine the most appropriate options for your condition.
