Link Between Laser Hair Removal and Skin Pigmentation Changes

Updated on: 28th Feb, 2023

Unwanted hair growth can be a source of frustration and embarrassment for many people. From facial hair to unwanted hair in sensitive areas, searching for a solution can be exhausting. Don’t fret! Laser hair removal is popular for those seeking a permanent solution.

However, the changes in skin pigmentation after laser hair removal has left many feeling uncertain about whether laser hair removal is the right choice for them.

Laser hair removal targets the pigment (melanin) in the hair follicle with a concentrated light beam. The laser heats the hair follicle, damaging it and preventing further hair growth.

Sometimes this heat can also damage the surrounding skin cells and structures which can cause pigmentation changes like hyperpigmentation (darkening of the skin) or hypopigmentation (lightening of the skin) in the treated area.

Hyperpigmentation: When the laser targets the hair follicle, the high heat can sometimes stimulate the melanin-producing cells in the surrounding skin, causing them to produce more melanin than usual. This can result in hyperpigmentation or darkening of the skin in the treated area. 

Hypopigmentation: Laser hair removal can also damage the melanin cells in the surrounding skin cells,when high parameters are used. This can  lead to a loss of pigment in the treated area or hypopigmentation. 

While skin pigmentation changes are generally mild and temporary, they can be more pronounced in individuals with darker skin tones, tanned skin or recent sun exposure. 

Here are a few steps to prevent change in skin pigmentation after laser hair removal treatment:

Choose a Qualified and Experienced dermatologist: Do your research and select a dermatologist who is knowledgeable, experienced, and has a good reputation for performing laser hair removal procedures.

Avoid Sun Exposure: Exposure to UV rays can increase the risk of skin pigmentation changes, so it’s best to avoid sun exposure (like beach vacations) or tanning for at least two weeks before and after your laser hair removal treatment.

Follow Pre- and Post-Treatment Instructions Carefully: Your dermatologist will give you specific instructions on preparing for and caring for your skin before and after the procedure. Follow these instructions closely to ensure the best possible outcome.

Avoid Heat Exposure: Avoid hot showers, saunas, and steam rooms for at least 24 hours after your treatment, as heat can increase the risk of pigmentation changes.

By following these steps, you can minimise the risk of developing pigmentation changes after laser hair removal and achieve the smooth, hair-free skin you desire.
