Underarm Brightening Laser

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 plucking — repeated 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.

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.

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.

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.

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:

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.
