Darkness of the underarms is a common complaint in people with our skin tone. They tend to get embarrassed to wear sleeveless because they are very conscious of the darkening in their underarms.
Underarms darkness is a common skin hyperpigmentation where the skin in the armpits becomes a few shades darker than the surrounding skin.
At Aakar Dermatology in Pulchowk, Lalitpur, we understand how dark underarms can affect your confidence. We offer comprehensive solutions — from identifying the root cause to providing advanced treatments like laser therapy, chemical peels, and microneedling.
Causes of Dark Armpits
Understanding why your underarms are dark is the first step toward effective treatment. Here are the three main causes:
1. Friction
If you have overweight or have lack of skin in the underarms or if you wear very tight fitted clothes, this can lead to darkening. When two surfaces rub against each other, it can lead to friction and darkening of the skin. If you have dark underarms, you would want to wear loose fitted clothes.
Friction is one of the most common causes of dark underarms in Nepal, especially during hot, humid weather when skin-to-skin contact increases.
2. Post-Inflammatory Hyperpigmentation (PIH)
If there is any kind of lesion in your underarms area, if you develop any kind of boils or a burn due to waxing or any kind of injury has occurred in your underarms, that can heal with pigmentation — so this is the reason.
Post-inflammatory hyperpigmentation is extremely common after:
- Waxing burns — hot wax damaging the delicate underarm skin
- Razor cuts or nicks — injuries from shaving
- Ingrown hairs — leading to inflammation and dark spots
- Boils or folliculitis — bacterial infections in hair follicles
- Allergic reactions — to deodorants or hair removal creams
3. Acanthosis Nigricans
It is a condition characterized by insulin resistance. Insulin is a hormone produced by an organ called the pancreas. When the body’s cells are unable to effectively use insulin, the pancreas compensates by producing more of it. This excess insulin can lead to thickening and darkening of the skin, especially in body folds.
Commonly affected areas include the forehead, around the mouth, the neck, underarms, beneath the breasts, and the groin. To evaluate this condition, you may need to check your fasting and postprandial insulin levels along with blood sugar levels.
Acanthosis nigricans is often associated with:
- Pre-diabetes or diabetes
- PCOS (Polycystic Ovary Syndrome)
- Obesity
- Hormonal imbalances
- Certain medications
If you notice darkening not just in the underarms but also in the neck, groin, or other body folds, consult Dr. Rajan Tajhya for a complete evaluation including blood tests.
How Can We Prevent the Underarms from Getting Darker?
Prevention is key to maintaining lighter, healthier underarms. Follow these dermatologist-approved tips:
1. No Wax
First and foremost, avoid waxing. Applying hot wax can injure the skin, and the process of pulling off the cloth or wax strip can further damage the delicate underarm area.
Waxing is one of the leading causes of dark underarms in Nepal, where salon waxing is very popular. The repeated trauma from hot wax and cloth strips causes chronic inflammation, leading to permanent pigmentation.
2. Avoid Hair Removal Creams
Hair removal creams contain strong chemicals that may irritate the skin. The underarm area is already sensitive due to sweat and friction, and applying irritants here can cause redness, irritation, and darkening of the skin.
Common irritating ingredients in hair removal creams include:
- Calcium thioglycolate
- Potassium thioglycolate
- Strong fragrances
- Preservatives
These chemicals can cause contact dermatitis, leading to post-inflammatory hyperpigmentation.
How to Remove Hair in This Area?
If waxing and creams are out, what’s the best way to remove underarm hair?
Safe Hair Removal Options:
- Shaving — The safest temporary method when done correctly with a sharp razor, shaving gel, and gentle technique.
- Laser Hair Reduction — The best long-term solution.
You can either choose to shave or go for laser hair reduction. Laser hair reduction works especially well for the underarms because the hair in this area is usually thick. It can reduce hair growth by 70–80%, and the remaining hair can be easily managed by shaving once every two to three months.
The regrown hair will be much finer and slower to grow, making it far easier to maintain. Therefore, instead of waxing or using hair removal creams, laser hair reduction is the best option for long-term results.
Benefits of Laser Hair Removal for Dark Underarms:
Reduces hair growth by 70-80% permanently
- No waxing trauma — prevents further pigmentation
- Finer, lighter regrowth — easy to manage
- Less frequent maintenance — shave every 2-3 months only
- Reduces ingrown hairs — prevents boils and inflammation
- Safe for dark skin — when done with proper laser technology
At Aakar Dermatology, we use the Milesman quadruple wavelength laser, which is FDA-approved and safe for all skin types, including darker skin tones common in Nepal.
Other Prevention Tips
Do Not Use Deodorant if You’re Concerned About Body Odor
Deodorant sprays are pressurized and also contain alcohol. This can really irritate the skin.
Instead:
- Use gentle, alcohol-free deodorants or natural alternatives
- Apply antiperspirant at night when sweat glands are less active
- Choose roll-on or cream deodorants over sprays
- Look for fragrance-free, hypoallergenic options
- Consider natural crystal deodorants or baking soda-based products
Wear Loose-Fitted Clothing
Make sure to wear loose-fitted clothing, especially while sleeping. Avoid garments that dig into your underarms. During the day, if you need to wear fitted clothes, ensure that at night you switch to something very loose, allowing your underarm area to remain free from friction.
Choose to wear cotton fabrics, as they are gentle on the skin and cause the least irritation.
Clothing Tips:
- Cotton is best — breathable and gentle
- Avoid synthetic fabrics (polyester, nylon) — trap sweat
- Loose nightwear — allows skin to breathe
- Avoid tight bras or blouses — reduce friction
- Light colors — don’t show deodorant stains
Treatment Options for Dark Underarms
If you already have dark underarms, several effective treatments are available at Aakar Dermatology:
1. Medication
Your dermatologist can prescribe medications to help lighten the skin under your arms.
Retinoid creams are considered the first-line treatment. When used regularly, they can help thin and lighten the skin in affected areas.
Other prescription medications may include:
- Hydroquinone — skin-lightening agent
- Kojic acid — reduces melanin production
- Azelaic acid — brightens and exfoliates
- Vitamin C serums — antioxidant and brightening
- Combination creams — tailored to your specific needs
2. Chemical Peels
Peels containing trichloroacetic acid (TCA) can help exfoliate the skin. This process helps remove the thicker, damaged skin to reveal new and smooth skin.
Chemical peels work by:
- Removing the outer pigmented layer of skin
- Stimulating new skin cell turnover
- Reducing melanin deposits
- Improving overall skin texture
At Aakar Dermatology, we customize peel strength based on your skin type and severity of pigmentation.
3. Laser Therapy
Advanced laser treatments can target and break down the excessive melanin, leading to gradual lightening of the underarms skin.
Laser therapy benefits:
- Precise targeting of pigmented areas
- Minimal damage to surrounding skin
- Effective for stubborn pigmentation
- Combines well with hair removal — solve two problems at once
- Safe for all skin types with proper technology
4. Lifestyle Modification
Dermatologists may suggest lifestyle changes, such as:
- Avoiding tight clothing
- Using gentle hair removal methods
- Adopting a healthy diet to manage the condition effectively
Additional lifestyle recommendations:
- Weight management — reduces friction
- Blood sugar control — if acanthosis nigricans is present
- Gentle exfoliation — removes dead skin cells
- Daily moisturization — keeps skin healthy
- Sun protection — prevents further darkening
5. Microneedling
If you want quick and fast results, microneedling is one of the best treatments for you. Microneedling is a skin treatment where a dermatologist uses a special pen-like device called a Derma pen. It has very fine needles that gently prick the skin at a controlled depth. These tiny pricks trigger your skin to heal itself by making more collagen, which helps improve skin texture and appearance.
How Microneedling Works for Dark Underarms:
- Creates micro-injuries in the pigmented skin
- Stimulates collagen production and skin renewal
- Enhances product absorption — allows lightening serums to penetrate deeper
- Breaks down melanin deposits gradually
- Improves skin texture and smoothness
Microneedling is especially effective when combined with:
- Vitamin C serums
- Growth factors
- Lightening agents
- Hydrating serums
Results are typically visible after 3-6 sessions spaced 4 weeks apart.

Frequently Asked Questions
The three main causes are:
- Friction from tight clothes, excess weight, or skin rubbing.
- Post-inflammatory hyperpigmentation from waxing, shaving injuries, boils, or allergic reactions.
- Acanthosis nigricans, a condition related to insulin resistance, diabetes, PCOS, or obesity.
Yes, it’s very common, especially in people with medium to dark skin tones. However, it can be treated effectively with the right approach. Consult a dermatologist to identify the cause and get proper treatment.
Yes, waxing is one of the leading causes of dark underarms. Hot wax can burn the delicate underarm skin, and pulling off the wax strip causes trauma. Repeated waxing leads to post-inflammatory hyperpigmentation (PIH), causing permanent darkening.
The best options are:
1. Laser hair removal — permanently reduces hair by 70-80% and prevents pigmentation from repeated trauma.
2. Shaving — when done gently with a sharp razor and shaving gel. Avoid waxing and hair removal creams as they cause irritation and darkening.
While natural remedies may provide mild improvement, professional treatments are more effective. For prevention: wear loose cotton clothes, avoid waxing/creams, use gentle deodorants, exfoliate gently, and moisturize daily. For treatment, consult a dermatologist for prescription creams, peels, or laser therapy.
Results depend on the cause and treatment method. Topical medications take 4-8 weeks. Chemical peels show results in 2-4 weeks. Laser therapy takes 4-8 weeks. Microneedling can show results in 2-6 weeks. Consistency and following your dermatologist’s treatment plan are key.
Yes! Laser hair removal not only reduces hair by 70-80% but also prevents further darkening by eliminating the need for waxing. Some laser treatments can also target melanin and help lighten existing pigmentation. It’s a dual-benefit treatment.
Yes, if the darkening is due to acanthosis nigricans — a condition characterized by velvety, dark patches in body folds (underarms, neck, groin). This is often associated with insulin resistance, pre-diabetes, diabetes, or PCOS. If you have darkening in multiple areas, get your blood sugar and insulin levels checked.
Yes, microneedling is very effective for dark underarms. It stimulates collagen production, enhances absorption of lightening serums, and breaks down melanin deposits. Results are typically visible after 3-6 sessions spaced 4 weeks apart. It’s one of the fastest treatment options available.
Yes, you can wear sleeveless clothes, but it’s best to apply sunscreen to the underarms if they’ll be exposed to sun. Sun exposure can worsen pigmentation. Also, avoid tight sleeveless tops that cause friction. Wear loose, breathable fabrics.
Not necessarily. With proper treatment and prevention, dark underarms can be significantly lightened or completely resolved. However, if the underlying cause (like friction, waxing, or insulin resistance) is not addressed, the darkening may return.
Avoid:
1. Waxing — causes trauma and PIH.
2. Hair removal creams — contain harsh chemicals.
3. Alcohol-based deodorants — irritate skin.
4. Tight clothing — increases friction.
5. Synthetic fabrics — trap sweat.
6. Harsh scrubbing — damages skin.
7. Sun exposure without protection.
Absolutely! Dark underarms affect both men and women. All treatments — medications, peels, laser, microneedling — are suitable for men. Many male patients at Aakar Dermatology seek treatment for dark underarms, especially if they’re active in sports or fitness.
