Underarm Laser Hair Removal: What To Know Before You Try It

Underarm hair is perfectly natural, but not everyone loves the way it looks. Shaving, waxing, and depilatory creams can remove underarm hair, but they all have drawbacks. Waxing is painful, shaving causes nicks and ingrown hairs, and hair removal creams have a strong, unpleasant smell.

If you are looking for a long-lasting solution to underarm hair, laser hair removal is a great option. Laser hair removal can reduce underarm hair without the inconveniences of other hair removal techniques. Save yourself time and energy, all while knowing you always have smooth, hair-free underarms.

What Is Underarm Laser Hair Removal?

Laser hair removal is a safe, effective process to remove underarm or unwanted hair anywhere on the face or body. The treatment uses a specialized laser to target the hair in the armpit area, destroying the follicle so it can’t grow new hair. Once hair is removed, you’ll have smooth, soft skin without stubble or painful ingrown hairs.

Another benefit of underarm laser hair removal is lightening the skin. You may find that the skin of your underarms is slightly darker than other parts of the body. Fortunately, laser treatments for highly pigmented areas can improve skin tone and remove discoloration.

How Does Underarm Laser Hair Removal Work?

Before you go for a laser hair removal appointment, you need to prepare your skin for the process. There are a few simple steps you need to take:

  • Avoid UV exposure and direct sunlight for at least a week before the treatment session.
  • Do not use tanning beds or tanning products like spray tan.
  • Do not wax or tweeze the area for six weeks before treatment. You may shave the hair, but don’t do anything to affect the hair follicle.
  • A light exfoliation a few days before treatment can remove dead skin cells and the build-up of any products like deodorant and lotions, making it easier to target the hair.

On the day of your appointment, your technician may offer you a numbing cream to alleviate discomfort. The laser feels like a rubber band snapping against your skin, which can be uncomfortable for the sensitive skin of the underarms. The technician will also clean the skin before beginning the treatment.

During the treatment, your technician will move a wand across your skin. The wand emits a laser, which heats the pigment in the hair under your arms. The heat damages or destroys the hair follicle, so it can’t grow new hair. The process takes about 10 minutes for each underarm.

After treatment, you may experience mild redness, swelling, or soreness. You can use cold compresses or over-the-counter pain medicine to manage the discomfort. You can return to normal activity right away.

How Long Does Laser Hair Removal Last?

Laser hair removal is long-lasting, but it is not permanent hair removal. Especially after multiple sessions, the results can last for several months or longer. This is because the hair follicles can heal over time and start growing hair again.

The hair that grows back tends to be less thick and coarse than before. You can safely get additional treatment to remove any regrowth.

How Many Sessions of Underarm Laser Hair Removal Will I Need?

You will probably need several sessions of laser hair removal for your underarms. Most people see optimal results after three to six sessions. Many people notice a significant difference in hair thickness before and after — even after one or a few sessions.

Laser hair removal treatment is only effective on the hairs that are in the active growth phase. Follicles in the resting phase won’t be affected, and they will produce new hairs when they return to the growth phase. Follow-up treatments are spaced six to eight weeks apart to catch hairs as they start growing back.

Cost of Laser Underarm Hair Removal

The amount you pay for laser underarm hair removal can vary depending on the size of the area and the number of sessions needed. In many areas, laser hair removal can cost around $100 to $500 per session.

However, you can book a single appointment for laser underarm hair removal at Lasers by Monica for just $75. Or, you can purchase a package of six sessions for the price of five.
