How does laser hair removal on the face work?

Laser hair removal works by sending a light into the hair follicle via laser, which is absorbed by the pigment, or melanin, in the hair — this is why it originally worked best on people with darker hair.

When the light is absorbed by the pigment, it’s converted to heat, which is what actually damages the follicle.

After the laser damages the hair follicle, the hair vaporizes, and a full round of treatments later the hair will stop growing back.

Laser hair removal may help prevent ingrown hairs and will save time typically spent waxing or shaving.

Procedure for laser hair removal on the face

Before the laser hair removal procedure begins, your face will be thoroughly cleaned and a numbing gel may be applied to the treatment area. You’ll be given goggles to wear, and your hair will likely be covered.

The practitioner will aim the laser at the specified area. Most patients say the sensation feels like a rubber band snapping against the skin, or a sunburn. You may smell the scent of burnt hair.

Because the face area is smaller than other parts of the body, like the chest or legs, laser hair removal on the face will generally be pretty quick, sometimes done in as little as 15–20 minutes.
