Darkened underarms are a common concern that can understandably make people feel self-conscious, especially when wearing sleeveless clothing. This hyperpigmentation often results from repeated shaving, friction, buildup of dead skin cells or hormonal changes.

Underarm brightening laser is a safe, medical-grade solution to address this. By targeting melanin in the skin, the laser breaks down pigments and stimulates skin renewal. Over a series of sessions, the underarm area can appear lighter, smoother and more uniform in tone.

At Cove Aesthetic Clinic, our doctors personalise each treatment plan to your skin type and sensitivity, ensuring visible improvement with comfort and safety in mind.

What causes Dark Underarms?

Dark underarms are a common concern, especially in humid climates like Singapore. Most cases are related to increased melanin production in the skin (hyperpigmentation) or to skin thickening from friction or irritation.

Melanin is the natural pigment that gives skin its colour. When the underarm skin becomes irritated, inflamed or repeatedly rubbed, the melanocytes in the area may produce more melanin, creating a visibly darker appearance over time.

Common contributing factors include:

  • Hormonal changes, genetics or underlying medical conditions — some individuals may be predisposed to darker skin in this area via hormonal fluctuations or medical conditions such as Acanthosis Nigricans.
  • Dead skin cell buildup, sweat and bacteria — a lack of appropriate cleansing may allow these to accumulate, contributing to uneven tone.
  • Regular shaving or pluckingrepeated skin irritation can trigger pigmentation changes and discolouration.
  • Use of deodorants and antiperspirants some products may contain irritants or chemicals that damage the skin over time and thus resulting in skin darkening
  • Friction and tight clothing constant rubbing of the underarm area with fabric or even hair can promote thickening and a darker appearance.
  • Sun exposure although less obvious under the arms, unprotected sun exposure can worsen pigmentation issues.

What is an Underarm Brightening Laser?

The underarm brightening laser treatment uses precisely targeted picosecond-pulse technology to safely and effectively improve dark or uneven underarm skin.

By focusing on areas with excess melanin, the laser promotes pigment reduction, helping to lighten discolouration and restore a more balanced, naturally radiant skin tone. This treatment is ideal for those who experience dullness, rough texture or hyperpigmentation in the underarm area and wish to achieve smoother, clearer and more even-toned skin.

How does the Underarm Brightening Laser work?

The treatment targets hyperpigmentation in the underarm area by delivering controlled bursts of picosecond laser energy. The energy is absorbed by melanin, breaking it down into smaller particles that the body can naturally remove. Over multiple sessions, this gradually lightens the skin, leaving it smoother, more even and brighter.

Some of the key points are:

  • The laser uses modern picosecond pulse technology, which emits ultra-short bursts of energy that penetrate the skin without causing excessive heat damage to surrounding tissue.
  • When the laser energy is delivered, it is absorbed by melanin in the pigmented skin. The pigment breaks apart, allowing the body’s natural healing processes to gradually remove the fragments.
  • The laser settings can be customised for energy level, pulse duration and coverage area, ensuring safe and uniform treatment even on sensitive under-arm skin.
  • To enhance comfort, the procedure may incorporate cooling methods or topical anaesthetics, protecting the outer skin while the laser works on pigments deeper in the dermis.

Benefits of Underarm Brightening Laser

The underarm brightening laser offers several distinct advantages, including:

  • Safety – the treatment is safe for all skin tones, including darker skin. This is because the picosecond technology uses ultra-short light pulses that limit unnecessary spread, reducing the likelihood of pigmentary side effects. 
  • Targeted brightening care this treatment specifically targets melanin, allowing the breakdown of pigmentation in a controlled and predictable manner. By minimising melanin in the skin, it supports gradual skin brightening and improvements in skin tone and texture. 
  • Patient satisfaction many patients appreciate the steady, visible improvements in pigmentation and the smoother, brighter underarm appearance that develops over time. 
  • Increased confidence  – patients feel more at ease and confident as underarm pigmentation gradually improves across sessions. This helps them feel more comfortable in day-to-day activities and clothing choices.
  • Minimal downtime – the underarm brightening laser is often called a “lunchtime treatment” as can be completed quickly with minimal downtime, allowing you to return to your day-to-day activities without disruption.

What to Expect during your procedure

Your underarm skin is delicate and treating hyperpigmentation requires precision and care. The underarm brightening laser is designed to deliver safe and effective results while keeping your experience comfortable.

From the initial consultation to each treatment session, our team ensures that you are fully informed, relaxed and supported. Every step is tailored to your skin’s needs, so you can feel confident throughout the process.

The procedure involves the following steps:

STEPSDESCRIPTIONS
Consultation and assessmentOur aesthetic doctors
will review your medical history and examine the underarm skin for pigmentation,
texture and tone. A personalised treatment plan will be designed based on your
concerns and goals.
PreparationThe area is thoroughly cleansed and a topical anaesthetic may be applied to support
comfort. Protective measures are put in place to ensure safety throughout the laser
session.
Laser deliveryThe handpiece is moved evenly across the underarm in controlled passes. Mild snapping
sensations, warmth or tingling may be felt as the laser targets pigmented areas.
Cooling and soothingA cooling gel or soothing product is applied after the session to reduce temporary
redness or sensitivity. Clear post-treatment instructions are provided to support
aftercare.
Follow-up schedulingSessions are typically spaced 3 to 4 weeks apart to allow the skin to recover as
pigment gradually breaks down. Your treatment schedule will be customised according
to your needs and response over time.

What results can you Expect

The laser produces gradual and progressive improvements, as pigments are broken down and the skin’s natural renewal processes are activated. A full treatment course ensures the best results. Results often reveal themselves as per the following time frame:
  • The underarm area may appear slightly brighter and feel smoother.
  • Mild improvements in texture and tone are noticeable.
  • Pigmentation is visibly reduced, creating a more even appearance.
  • Skin texture improves, with underarms feeling softer and refreshed.
  • Significant lightening of darkened areas, with smoother and more even-toned skin.
  • The underarm area feels comfortable, healthy and confident without relying on topical products alone.
  • Results are generally long-lasting, but habits that cause physical or chemical irritation (i.e. shaving, friction, using inappropriate skincare products) may lead to the recurrence of underarm hyperpigmentation. This is why understanding the underlying causes and adopting the right aftercare is essential for maintaining and prolonging your results. 
  • Occasional maintenance sessions may be recommended to maintain the good results. 

Overall, you can expect underarm skin that is progressively lighter, smoother and more uniform, helping you feel confident in sleeveless clothing and daily activities.

Post-treatment care for Underarm Brightening Laser

Proper aftercare is key to optimising results and maintaining the health of your underarm skin following treatment. The area may be slightly sensitive or warm immediately after the session, but following these guidelines will support healing, prevent irritation and help prolong your results.

  • Keep the area clean and dry gently cleanse the underarms with a mild, fragrance-free cleanser. Avoid scrubbing or using abrasive products.
  • Avoid friction and tight clothing wear loose, breathable fabrics to prevent rubbing and irritation while the skin recovers.
  • Skip deodorants – refrain from applying antiperspirants or deodorants as they frequently contain alcohol or chemicals that may irritate skin. 
  • Protect from heat and sweating avoid saunas, hot showers, intense workouts or sun exposure for 24 to 48 hours after treatment, as heat can aggravate sensitive skin.
  • Moisturise gently apply a gentle plain moisturiser to maintain hydration and comfort.
  • Monitor your skin some redness or mild tingling is normal and typically resolves within a few hours. Contact our clinic if you notice unusual swelling, blistering or persistent discomfort.
  • Follow your treatment schedule abide by the recommended time frame for treatments in order to optimise recovery time and efficacy in the dissolution of hyperpigmentation.
