What is Laser Hair Removal?

Laser hair removal is a medical procedure to remove unwanted hair with the use of a concentrated beam of light (laser). Laser hair removal removes unwanted hair from the face, underarms, back, legs, and bikini area by emitting powerful, pulsating beams of light. Despite the fact that laser hair removal effectively reduces hair growth, but it does not ensure permanent hair removal. Patients with various skin types can benefit from laser hair removal, but those with light skin and dark hair will have the best results. Hair removal typically necessitates multiple treatments. You may require at least six treatments spaced a few weeks apart for the best effects.

How Does Laser Treatment Work?

Lasers emit a single-color wavelength of light. This light is used to target the pigment in individual hairs in laser hair removal. The light passes through the hair shaft and into the hair follicle. The heat from the laser damages the hair follicle, making it impossible for a hair to grow from it. Hair has its own growth cycle, consisting of periods of rest, shedding, and growth. Hair in the resting phase can not be seen by the technician or laser, thus it may be necessary to wait until it regrows before removing it. 

Side Effects of Laser Hair Removal

Side effect risks vary depending on skin type, hair color, treatment plan, and pre-and post-treatment upkeep. The following are the most common laser hair removal adverse effects:

  • Redness
  • Swelling
  • Discomfort

As a result of laser hair removal, the affected skin may darken or lighten. These modifications could be temporary or permanent. All those who don’t avoid sun exposure before or after treatment, as well as those with darker skin, are the most affected by skin whitening. 

Blisters, crusting, scarring, or other changes in skin texture are rare side effects of laser hair removal.

Due to the risk of severe eye injury, laser hair removal is not suggested for eyelids, brows, or adjacent areas.

It’s also critical to adhere to your dermatologist’s advice. Following the recommendations before and after treatment will greatly reduce your chances of experiencing side effects. A person should avoid the sun after having their hair removed. 

What to do Before and After Getting Laser Hair Removal?

The most important thing when you opt for laser hair removal is to know the pre-treatment care and aftercare of laser treatment. The targeted area will be cleansed before treatment starts. Sunless skin lotions that darken your skin should be avoided. Avoid sun exposure before and after treatment, as directed by your doctor. Before the treatment, check with your doctor to see what medications you should avoid. The hair follicle can be disturbed by the waxing, plucking, and electrolysis so you must be avoided for at least four weeks prior to the treatment. 

Follow the after-care instructions provided by your dermatologist. Apply ice to the affected area to relieve any discomfort. Avoid shaving, waxing, or plucking hair for 24 hours after treatment, exfoliation, extreme sweating, swimming, and very hot showers. Every day, apply a broad-spectrum SPF30 sunscreen. Do not use any tanning beds, sunlamps, or other indoor tanning devices. If a blister appears, you do not need to puncture it. Also, apply antibiotic ointment to any broken skin till it heals. To avoid any side effects, remember to follow these pre-and post-treatment instructions.
