Whether it’s on your chin, underarms, or bikini area, there might be some body hair that bothers you and that you wish you could banish for life. Can you do it with laser hair removal? And more importantly, is laser hair removal safe?
Here’s the full scoop on laser hair removal: how it works, who it’s good for, and any safety concerns that come along with it.
First things first, here’s how laser hair removal works.
Laser hair removal is the process of using light-based energy to target hair follicles under the skin, which reduces hair growth in the treated area, says Deanne Robinson, MD, president and co-founder of Modern Dermatology of Connecticut.
It should actually be referred to as laser hair reduction, as it does not remove 100 percent of the treated hair in the area. The real number is approximately 80 percent removal if you do a series of treatments.
There are a few different types of lasers, and your doctor should ultimately decide which one is best for you to achieve optimal results, says Howard Sobel, MD, dermatologist and founder of Sobel Skin.
The Diode Laser is very effective for light and dark skin tones. The Alexandrite Laser is the fastest of all lasers, and it works best for treating larger body areas on patients who have light-to-olive complexions. The Nd:YAG can be used safely on all skin types, including tanned skin. Keep in mind, it is less effective for light or fine hair when compared to other types of lasers.
And according to Dr. Sobel, the LightSheer DUET High Speed Laser is considered the industry gold standard in laser hair removal. It works on a range of hair and skin tones, including tanned skin, and has been proven to improve the appearance of razor bumps, benign pigmented lesions, sun damage, and superficial leg veins, all in addition to removing hair.
This treatment is only for medium to dark hair colors—sorry blondies.
Laser hair removal targets the pigment within the hair bulb, says Dr. Robinson. Blonde or white hair lacks pigment and is not able to be treated with the lasers that are currently available.
FYI: Laser hair removal is not a one-time deal.
Multiple treatments are usually needed to achieve the best results. Since hair grows in cycles, one treatment will not be able to catch and destroy all hair follicles, says Dr. Sobel.
Most people experience great results after three to five treatments, spaced four to eight weeks apart. It’s hard to predict how different people’s hair will respond—the length and quantity of treatments really depends on the body part you are treating and the individual’s response to the treatment.
To keep it safe, look for goggles and masks.
Eye protection is critical with laser hair removal (just as it is for any laser or light-based procedure) to prevent injury to the eyes, says Dr. Robinson. Both you and the doctor or technician performing the procedure should always have goggles on when the laser is in process.
The other safety concern is exposure to the laser plume (aka the smoke, vapor, and particles released while lasering). The biggest risk is to those who perform the procedure and are exposed to the plumes frequently, says Dr. Sobel. The dust particles are very small and can potentially irritate your airways over time and continual exposure. Any practitioner performing laser hair removal should wear a surgical mask to minimize a potential reaction, but it is not necessary for the patient receiving the treatment.
