Laser Hair Removal

Introduction

Laser hair removal is a cosmetic treatment that removes unwanted body hair by focusing laser beams of light. In order to stop or slow down hair development, the laser damages and heats the melanin (pigment) in the hair follicles. Any region of the body, including the face, legs, arms, underarms, and bikini area, can be treated with this technique. Because it can produce long-lasting results and is less painful than conventional hair removal techniques like waxing or electrolysis, laser hair removal is a common method of hair removal. As hair grows in various stages and the laser is only effective during the active growth phase, it may take several treatment sessions to get the desired results.

Pathophysiology

A specialised laser that produces a focused beam of light is used in the pathophysiology of laser hair removal. The melanin (pigment) in the hair follicle absorbs the laser light, heating up and damaging the follicle, which inhibits or delays hair development. People with darker hair and lighter skin typically have better outcomes with this therapy because the laser targets the melanin in the hair follicle. Because the pigment in hair attracts the laser light, the more pigment there is in the hair, the more effectively the laser will damage the hair shaft. The targeted region of skin is exposed to the laser during the procedure.

Side Effects

Some common side effects that may occur during or after laser hair removal include:

Slight discomfort: During laser hair removal, many people report slight discomfort, a feeling of heat, or stinging.
Redness and swelling: After laser hair removal, some redness and swelling in the treated region is typical.
Skin irritation: The laser hair removal procedure may result in some skin irritation, including stinging, burning, or itching in the treatment region.
Epidermis discoloration: In rare instances, laser hair removal can result in hyper- or hypopigmentation of the epidermis.
Scarring: Although it is uncommon, laser hair removal can leave scars, particularly if the procedure is not carried out by a trained expert.
Regrowth of hair: Laser hair removal is not always 100% successful, and some people may experience regrowth of hair in the area that was previously treated.

How do Dermatologists do Laser Hair Removal ?

Dermatologists frequently administer laser hair removal procedures using specialised laser equipment. The hair follicles are damaged by the laser’s intensely concentrated light beam, which is then absorbed by the pigment (melanin), stopping further hair development. The dermatologist will first clean the treatment area and apply a cooling gel to help protect the skin and lessen discomfort before starting the process. Short light pulses are then directed at the hair follicles by the laser device as it is applied to the epidermis. The treatment area’s dimensions and the volume of hair being removed will determine how long it takes.

After the procedure, the dermatologist will give directions on how to take care of the treated area. These instructions may include avoiding exposure to the sun and using a moisturiser to relieve any skin irritability. To obtain the desired results, several sessions may be required, usually separated by a few weeks to give time for hair regrowth and subsequent treatment.
