Have you ever wondered about the four different types of lasers used for hair removal? Do you know which ones are right for you?
Here is a brief explanation of each kind of laser and its importance in the field:
Common brand names include Candela GentleLase, Cynosure Apogee, EpiTouch Plus
The Alexandrite laser’s main advantages are that it has a shorter wavelength system compared to other types of lasers, and it can treat a larger area of skin faster. While the Alexandrite laser is safe and effective on a wide range of skin types, those with light skin are the best candidates, given that it can result in discoloration on darker skin types.
Common brand names include Palomar E2000 and RubyStar
The Ruby laser, one of the oldest types of lasers used in hair removal, is best suited for those with light or fine hair and fair skin. Compared to the newer laser technologies, the Ruby laser can be more time-consuming because it covers a smaller area of skin at a time.
Common brand names include LightSheer, SLP 1000, LaserLite, and SopranoXL
The Diode laser is one of the newest and most commonly used lasers today. It is designed for fair to medium skin tones. Compared to other lasers like the Alexandrite or Ruby, the Diode laser has a longer wavelength of light, reducing the risk of skin damage than lasers with shorter wavelengths. What is more, the Diode laser has a fast repetition rate, meaning it can treat large areas of the body quickly.
Nd and LP Nd: YAG
Common brand names include Cutera CoolGlide, Cynosure Elite, Altus Cool Glide, and Candela GentleYAG
The Nd and LD Nd: YAG laser is the preferred laser for darker skin, but it also requires more treatments for similar results that other lasers can achieve. Treatments with this laser can also be more painful and less effective on fine hair. One advantage of the LD and Nd: YAG laser is that it uses the longest wavelengths out of all four lasers, meaning it has the most potential to destroy hair at the very bottom of the shaft.
Each of these lasers has been FDA-approved for laser hair removal. They are proven effective, fast and safe methods for successful hair removal and permanent hair reduction. Your dermatologist will select the laser most appropriate for you depending on your hair and skin type and area of the body.
Remember: Compared to shaving or waxing, all four types of lasers for hair removal achieve longer lasting results with less frequent maintenance.
