Brighten Up: A Guide to Underarm Whitening

Having dark underarms can be a source of self-consciousness for many individuals, affecting their confidence and wardrobe choices. While it’s a common concern, understanding the causes and available treatments can help you regain confidence and achieve underarm whitening. In this article, we will explore the various causes of dark underarms and discuss the treatments available, with a special focus on the innovative Pico Laser treatment and other non-surgical underarm whitening solutions in Singapore.

Causes of Dark Underarms

Friction and Irritation

One of the primary causes of dark underarms is friction and irritation. The constant rubbing of the skin in the underarm area due to tight clothing, shaving, or the use of harsh deodorants can lead to the accumulation of dead skin cells and melanin, resulting in darkening over time. To avoid this, opt for looser clothing, consider waxing instead of shaving, and use gentle, hypoallergenic deodorants.


Hyperpigmentation is another common cause of dark underarms. It occurs when there is an overproduction of melanin in the skin, leading to darker patches. Factors such as genetics, hormonal changes, and exposure to UV rays can contribute to hyperpigmentation. To mitigate this, apply sunscreen to your underarms when exposed to the sun and consider hormonal management if needed.

Poor Hygiene

Lack of proper hygiene can also lead to dark underarms. Sweating and the buildup of bacteria can result in discoloration. Regularly cleansing the underarm area, exfoliating, and ensuring it stays dry can help prevent this cause of darkening.

Post-Inflammatory Hyperpigmentation

Post-inflammatory hyperpigmentation is a condition where the skin becomes darker after an injury or inflammation, such as after shaving or waxing. To prevent this, make sure to use a sharp and clean razor, and avoid harsh hair removal methods that can cause irritation.

Skin Disorders

Certain skin disorders like acanthosis nigricans can cause darkening of the underarms. This condition is often associated with insulin resistance and obesity. Managing these underlying health issues can help improve the appearance of dark underarms.

Treatment Options for Dark Underarms

Pico Laser Underarm Whitening Treatment

In recent years, Pico Laser underarm whitening treatment has gained popularity as a highly effective solution for dark underarms. This cutting-edge technology utilizes picosecond laser pulses to break down melanin deposits in the skin, resulting in a lighter and more even tone.

How Pico Laser Works

Pico Laser works by emitting ultra-short laser pulses that target melanin in the skin without causing damage to the surrounding tissue. The rapid bursts of energy effectively shatter the melanin into tiny particles, allowing the body’s natural processes to eliminate them gradually. This process helps in lightening the underarm area and achieving a more uniform skin tone.

Benefits of Pico Laser Underarm Whitening Treatment

  • Quick and Painless: Pico Laser treatments are relatively quick, usually taking less than 30 minutes per session, and are virtually painless. Patients can resume their daily activities immediately after the procedure.
  • Minimal Downtime: Unlike some other treatments, Pico Laser requires minimal downtime, making it convenient for individuals with busy schedules.
  • Visible Results: Most patients notice visible improvements in underarm pigmentation after just a few sessions. For optimal results, multiple sessions may be recommended.
  • Long-lasting Effects: Pico Laser underarm whitening treatment provides long-lasting results, with many patients experiencing a significant reduction in darkening that can last for years.
  • Safe and Non-invasive: Pico Laser is a safe and non-invasive procedure that does not require incisions or anesthesia.

Other Non-Surgical Underarm Whitening Treatments

In addition to Pico Laser, there are several other non-surgical underarm whitening treatments available in Singapore. These treatments may be suitable for individuals with different needs and preferences:

Chemical Peels: Chemical peels involve the application of a chemical solution to the underarm area, which exfoliates the top layer of skin, promoting the growth of new, lighter skin. This treatment can be effective in reducing dark underarms, but it may require multiple sessions.

Topical Whitening Products: Various over-the-counter and prescription topical products containing ingredients like alpha hydroxy acids (AHAs), kojic acid, and vitamin C can help in gradually lightening the underarm area. These products should be used consistently for best results.

Microdermabrasion: Microdermabrasion is a non-invasive procedure that uses a machine to exfoliate the skin’s surface, promoting the growth of new, lighter skin. It can help improve the appearance of dark underarms, but multiple sessions may be necessary.

Laser Hair Removal: Laser hair removal not only removes unwanted hair but can also help lighten the underarm area by reducing friction and irritation. Over time, this can lead to a reduction in darkening.

Natural Remedies: Some individuals prefer natural remedies like applying lemon juice, yogurt, or aloe vera to their underarms to lighten dark spots. While these remedies may provide some benefits, results can be gradual and may vary from person to person.


Dark underarms can be a common concern, but understanding their causes and the available treatment options can help individuals regain confidence and achieve underarm whitening. Pico Laser underarm whitening treatment is an innovative and effective solution that utilizes advanced laser technology to target and break down melanin deposits in the skin, resulting in a lighter and more even tone. Additionally, other non-surgical treatments such as chemical peels, topical whitening products, microdermabrasion, and laser hair removal are available to cater to different preferences and needs. To explore underarm whitening treatments in Singapore, consult with a qualified dermatologist or skincare specialist who can recommend the most suitable option based on your individual circumstances.
