Does Laser Hair Removal Help with Hyperpigmentation?

Hyperpigmentation is a common skin condition characterized by darkening some skin regions due to an excess of melanin. This condition can be caused by various factors, including sun exposure, hormonal changes, and inflammation. Finding effective treatment options is often a top priority for individuals with hyperpigmentation. Laser hair removal, a popular cosmetic procedure for hair reduction, has been suggested as a potential solution for improving hyperpigmented skin. But does laser hair removal help with hyperpigmentation?

What is Hyperpigmentation

Before delving into the potential benefits of laser hair removal, it’s essential to understand the nature of hyperpigmentation. Melanin is a pigment responsible for determining skin color, hair, and eyes. When melanocytes, the cells that produce melanin, become overactive, hyperpigmentation can occur. The excess melanin can gather in specific areas, resulting in dark patches or spots on the skin.

Causes of Hyperpigmentation

  1. Sun Damage: Prolonged exposure to UV rays can stimulate melanin production, leading to freckles, age spots, and melasma.
  2. Hormonal Changes: Pregnancy, birth control, and hormonal imbalances can trigger hyperpigmentation, such as melasma or the “mask of pregnancy.”
  3. Inflammation: Conditions like post-inflammatory hyperpigmentation can result from acne, cuts, or other skin injuries.
  4. Skin Aging: As skin ages, it becomes more prone to developing hyperpigmentation, particularly in age spots.

What is Laser Hair Removal

Laser hair removal is a cosmetic procedure that aims to reduce or eliminate unwanted hair by using concentrated beams of light to target the hair follicles. The laser’s energy is absorbed by the pigment in the hair, generating heat that damages the follicle, inhibiting future hair growth. While laser hair removal is primarily sought for hair reduction, some individuals have reported an improvement in hyperpigmentation in treated areas.

Does Laser Hair Removal Help with Hyperpigmentation?

We know there are several methods to use to treat hyperpigmentation like topical creams or chemical peels. But if they haven’t worked, you might wonder, does laser hair removal help with hyperpigmentation? Laser hair removal is one of the best and safest hyperpigmentation treatments. I would recommend trying it before any other invasive methods. There are several ways in which laser hair removal will  positively impact hyperpigmentation:

  1. Targeted Melanin Absorption: Laser hair removal primarily targets melanin in the hair but can also affect the surrounding skin. When the laser energy is absorbed by excess melanin in the skin, it can break down melanin particles, potentially reducing the appearance of hyperpigmentation.
  2. Stimulation of Collagen Production: Laser treatments, including hair removal, can stimulate collagen production in the skin. Collagen is essential for skin’s elasticity and repair. An increase in collagen may help in reducing the visibility of hyperpigmented areas.
  3. Exfoliation: The laser energy used in hair removal can have an exfoliating effect on the skin. This will help remove the epidermis’s top layers, where hyperpigmentation often resides.
  4. Reduced Irritation: Hyperpigmentation can sometimes result from skin irritation or inflammation, such as post-inflammatory hyperpigmentation (PIH). Laser hair removal can help prevent ingrown hairs and reduce skin irritation, thereby minimizing the risk of PIH.

What is the best laser hair removal for hyperpigmentation?

If you are looking for the best laser hair removal procedures to help with hyperpigmentation, I suggest you try the following.

  1. Alexandrite Laser: Effective for light to olive skin tones, this laser is known for its precision targeting hair follicles.
  2. Nd:YAG Laser: Suitable for all skin types, the Nd:YAG laser has a longer wavelength that can penetrate deeper, potentially impacting hyperpigmentation.
  3. Diode Laser: This laser is often used for lighter skin tones and has a broad application for hair removal.
  4. Intense Pulsed Light (IPL): While not technically a laser, IPL devices are commonly used for hair removal. They emit a broad light spectrum that can target hair and skin pigment.

Does laser permanently remove hyperpigmentation?

Yes, laser will remove hyperpigmentation permanently. However, it doesn’t prevent you from getting hyperpigmentation in the future if your skin is exposed to stressors like sun damage and acne. To prevent hyperpigmentation in the future, follow all instructions given after the hair laser treatment and develop a skincare routine. Most importantly, protect your skin from sun damage. 

How many laser treatments does it take to get rid of hyperpigmentation?

Many people say they noticed results with the first treatment. However, this will depend on your skin type and the severity of your hyperpigmentation. Generally, you’ll need three to four sessions to get rid of hyperpigmentation. But in severe cases, you might have five to six sessions.

Research and Clinical Studies

Several clinical studies and trials have been conducted to determine the efficacy of laser hair removal in treating hyperpigmentation. In many cases, the results have been promising. However, it is essential to note that individual responses can vary significantly. Some studies have shown the following:

  • A study published in the Journal of Cosmetic Dermatology in 2013 found that 80% of participants with melasma experienced improvement in their condition after receiving laser hair removal treatments.
  • A 2018 study in the Journal of Clinical and Aesthetic Dermatology noted a significant reduction in post-inflammatory hyperpigmentation (PIH) in patients who underwent laser hair removal for hair removal purposes.
  • Research published in Dermatologic Surgery in 2006 suggests that laser hair removal can improve the appearance of lentigines, or age spots, with minimal risk of complications.
  • A study in the Journal of the European Academy of Dermatology and Venereology in 2011 concluded that long-pulsed Nd:YAG laser treatments were effective for treating post-inflammatory hyperpigmentation.

While these studies indicate positive outcomes, it’s essential to consider that not all individuals respond the same way to laser treatments, and the efficacy may vary depending on the type and severity of hyperpigmentation.

Safety Considerations and Risks

Laser hair removal is generally considered safe when performed by trained professionals. However, there are potential risks and considerations to keep in mind:

  1. Skin Type: The effectiveness and safety of laser hair removal can vary depending on skin type. People with darker skin tones may be at a higher risk of complications, including burns and changes in pigmentation.
  2. Hyperpigmentation Risk: Paradoxically, laser hair removal can also cause hyperpigmentation, especially in individuals with darker skin. Therefore, carefully assessing the patient’s skin type and condition is essential before treatment.
  3. Sun Exposure: Patients are typically advised to avoid sun exposure before and after laser hair removal sessions. Sun exposure can increase the risk of complications, including hyperpigmentation.
  4. Multiple Sessions: Significant hyperpigmentation improvements often require multiple laser hair removal sessions. This can be time-consuming and costly.
  5. Post-Treatment Care: Proper post-treatment care is essential. Patients are often advised to use sunscreen and avoid certain skincare products that may irritate the skin.

Patient Selection and Consultation

Before undergoing laser hair removal to address hyperpigmentation, you must have a thorough consultation with a qualified dermatologist or laser technician. During the consultation, the following factors should be considered:

  1. Skin Type: The patient’s skin type and ethnicity are vital in determining the most suitable laser technology for the procedure.
  2. Hyperpigmentation Type: The specific type of hyperpigmentation should be identified. Not all hyperpigmentation responds the same way to laser treatments.
  3. Medical History: Any underlying medical conditions and medications should be disclosed to assess potential contraindications.
  4. Expectations: Realistic expectations should be set. Laser hair removal may not wholly eliminate hyperpigmentation, and multiple sessions may be required.
  5. Sun Exposure: Patients should avoid sun exposure and tanning beds before and after treatments.

Post-Treatment Care

Proper post-treatment care is essential for maximizing the benefits of laser hair removal in addressing hyperpigmentation:

  1. Sun Protection: Sunscreen with a high SPF should be used daily to protect the treated areas from UV damage.
  2. Avoid Irritants: Harsh skincare products or exfoliants should be avoided, especially in the days following a treatment.
  3. Moisturize: Keeping the skin well-moisturized can aid in the healing process.
  4. Follow-up Sessions: Patients should adhere to the recommended schedule for follow-up sessions to achieve optimal results.


Laser hair removal can help in the treatment of hyperpigmentation. Targeting melanin in both the hair and surrounding skin, stimulating collagen production, and offering an exfoliating effect can help reduce hyperpigmented areas’ appearance. However, it’s crucial to recognize that individual responses can vary, and the safety and efficacy of laser hair removal depend on factors such as skin type, hyperpigmentation type, and proper post-treatment care.

Patients interested in using laser hair removal to address hyperpigmentation should consult a qualified dermatologist or laser technician to assess their suitability for the procedure and develop a customized treatment plan. While laser hair removal can be a practical option, it is not a one-size-fits-all solution, and careful consideration of the risks and benefits is essential before undergoing the procedure.
