As an antioxidant and vitamin-rich fruit, cucumber can promote skin lightening and reduce inflammation.

Aloe vera helps lighten dark marks and moisturize the skin, promoting overall health. The use of aloe vera gel as part of your skincare regimen can help fade dark spots and maintain underarm skin elasticity.


The nutritional value of yogurt and its ability to lighten dark marks under the arms make it a great snack. Lactic acid helps exfoliate the skin and stimulate cell turnover, reducing pigmentation.

Apply plain yogurt to the underarm area, let sit for 15-20 minutes, and then rinse with lukewarm water. It is suggested that you use yogurt regularly in order to even out your skin tone and diminish the appearance of dark spots.


The natural bleaching agent curcumin also contains powerful antioxidants and anti-inflammatory properties that lighten marks under the arms.

Medical Treatments For Dark Marks Under The Arms Caused By Cycling

While natural remedies can effectively remove dark marks under the arms, some people may opt for medical treatment prescribed by dermatologists for faster and more targeted results.

These medical interventions, from topical creams to advanced procedures, offer professional solutions to address skin concerns and help people achieve smoother, brighter underarm skin for enhanced confidence during cycling activities.

Topical Creams

Dermatologists often recommend topical creams as a first-line treatment for lightening dark underarms. These prescription creams typically contain active ingredients that target hyperpigmentation and promote skin renewal. When used consistently as directed, topical creams can help fade dark marks, even out skin tone, and improve skin texture in the underarm area.

Laser Treatment

Laser treatment is popular for people seeking fast, long-lasting results in lightening dark underarms. This procedure uses concentrated light beams to target pigmented areas and break down melanin deposits. Laser treatment can effectively lighten dark marks, increase collagen production, and rejuvenate the skin to achieve a smoother, more even-toned underarm complexion.


Microdermabrasion is a noninvasive exfoliation technique that can be beneficial in treating dark marks under the arms. Handheld equipment removes the outer dead skin cells and reveals brighter skin beneath. With multiple treatments over time, microdermabrasion promotes cell turnover, improves skin texture, and reduces dark spots.

Chemical Peels

Chemical peels are another effective medical treatment for lightening dark underarms. These peels contain various acids, such as glycolic or salicylic acid, that exfoliate the skin and promote cell regeneration. Chemical peels help reduce hyperpigmentation, even out skin tone and enhance skin clarity. Dermatologists can customize the strength of the chemical peel based on individual skin needs and desired outcomes.

Topical Treatments Prescribed by Dermatologists

Topical Treatments Prescribed by Dermatologists

Dermatologists may recommend specific topical treatments containing potent ingredients to address hyperpigmentation and effectively lighten dark underarms. These prescribed products are planned to target melanin production, enhance skin renewal, and promote a more uniform skin tone. When used under the guidance of a dermatologist, these topical treatments can deliver visible results in minimizing dark marks and improving overall skin quality.


Hydroquinone is a commonly prescribed skin-lightening agent that inhibits melanin production. Dermatologists may recommend hydroquinone-based creams to treat dark marks under the arms and hyperpigmentation. Regular application of hydroquinone can help lighten dark spots and make your skin look more even.


Retinoids are derivatives of vitamin A that are known for their skin-renewing properties. Dermatologists often prescribe retinoid creams to address various skin concerns, including hyperpigmentation. Retinoids promote cell turnover, reduce melanin production, and improve skin texture, effectively reducing underarm dark spots.

Kojic Acid

Kojic acid is a natural skin-brightening agent derived from fungi that inhibits melanin production. Dermatologists may recommend kojic acid-containing products to reduce hyperpigmentation and lighten dark marks. Kojic acid is gentle on the skin and helps to even out skin tone over time with consistent use.

Azelaic Acid

Azelaic acid provides skin-lightening and anti-inflammatory benefits. Dermatologists may prescribe azelaic acid creams to target hyperpigmentation, including dark marks under the arms. Azelaic acid helps fade dark spots, reduce redness, and improve skin tone and clarity.

Vitamin C Serums

Vitamin C serums are antioxidant-rich formulations that can help brighten the skin and reduce hyperpigmentation. Dermatologists often recommend vitamin C serums for their skin-brightening effects and ability to promote collagen production. Regular use of vitamin C serums can lighten dark marks, enhance skin radiance, and improve overall skin health.

6 Preventing Underarm Darkening While Cycling

Cycling is rewarding and stimulating, but it can sometimes lead to underarm darkening due to friction and sweat. To maintain smooth and even-toned underarm skin while enjoying your cycling adventures, consider implementing these straightforward yet effective preventive measures:

Avoiding Harsh Soaps And Deodorants

Opt for gentle, pH-balanced soaps and deodorants to avoid irritating the delicate skin of your underarms. Harsh products strip the skin of its oils, leading to dryness and potential darkening. Look for mild formulations for sensitive areas to keep your underarms clean and healthy.

Exfoliating Regularly to Remove Dead Skin Cells

Be sure to exfoliate regularly as part of your skincare routine to avoid the accumulation of impurities that may contribute to dark marks. You can use an exfoliating brush or scrub to promote cell turnover and achieve smoother, brighter underarm skin. Be mindful not to over-exfoliate, which can cause irritation and exacerbate pigmentation issues.

Skin Pigmentation and Sunscreen

Ensure your sunscreen has a minimum SPF of 30 to shield your underarms from harmful UV rays during outdoor rides. Sun exposure can worsen skin darkening and pigmentation, so make sunscreen application a habit before heading out for a cycling session. Reapply sunscreen regularly, especially if sweating profusely or spending extended periods in the sun.

Avoiding Shaving or Waxing:

Consider alternative hair removal methods like trimming or using depilatory creams to reduce friction and irritation on the underarm skin. Shaving or waxing can exacerbate dark marks by causing micro-trauma to the skin. Explore hair removal options that are gentler on the skin to minimize the risk of underarm darkening.

Wear Breathable Fabrics

Choose moisture-wicking, breathable fabrics for your cycling attire to keep your underarms dry and comfortable. Fabrics like nylon, polyester, or spandex can help wick away sweat, reducing friction and minimizing the likelihood of skin darkening. Opt for loose-fitting clothing to allow air circulation and prevent excessive sweating.

Post-Cycling Skincare Routine

After your cycling session, practice a post-exercise skincare routine to cleanse and soothe your underarms. You should use a mild cleanser to remove sweat and dirt and a hydrating moisturizer to replenish lost moisture. Applying a soothing aloe vera gel or cream that may occur post-ride may be helpful.

Cyclists’ Best Practices For Underarm Skin Care

Cyclists' Best Practices For Underarm Skin Care

Caring for your underarm skin is essential for maintaining its health, smoothness, and overall appearance. By following these best practices in underarm skincare, you can keep this sensitive area nourished, protected, and free from common issues like dark marks and irritation:

Regular Cleansing

Make it a habit to cleanse your underarms regularly to get rid of sweat, bacteria, and impurities that can accumulate throughout the day. Thorough cleansing helps prevent odor, breakouts, and skin irritation in this often-overlooked area.


To prevent ingrown hairs, exfoliate regularly to slough off dead skin cells. Clogged pores can result in dark marks, so exfoliating can promote skin renewal, enhance smoothness, and reduce dark spots.

Hair Removal

Choose hair removal methods like trimming, depilatory creams, or professional waxing to minimize skin irritation and reduce the risk of ingrown hairs. Avoid frequent shaving, which can lead to razor burn and darkening of the skin, particularly in the delicate underarm area.


After cleansing, apply a lightweight, non-comedogenic moisturizer to hydrate your underarm skin. Moisturizing helps maintain skin elasticity, prevent dryness, and support overall skin health. Opt for fragrance-free formulas to minimize the risk of irritation.

Avoiding Harsh Products

Avoid harsh soaps, deodorants, and skincare products that remove natural oils and cause sensitivity. Instead, choose gentle, hypoallergenic formulations to protect the delicate underarm skin from potential irritation and inflammation.

Allowing the Skin to Breathe

Cotton is a breathable, loose-fitting fabric that allows air to circulate and prevents sweating. Avoid tight garments that can trap moisture and lead to bacterial growth, ultimately contributing to skin issues like dark marks and odor.

Sun Protection

Apply broad-spectrum sunscreen to protect your underarms from harmful UV rays. Sun protection is crucial for maintaining the health and appearance of your underarms.

After-Shaving Care

After shaving, soothe your underarms with a calming gel or lotion to reduce redness, inflammation, and irritation. Avoid applying harsh aftershaves containing alcohol, as they can exacerbate skin sensitivity and lead to discomfort post-shave.

Good Hygiene Practices

Good Hygiene Practices

Practice good hygiene by showering regularly, especially after physical activities like exercise. Use an antibacterial soap to cleanse the underarms and keep bacteria at bay. Dry the skin thoroughly to prevent fungal infections and maintain underarm freshness.

Healthy Lifestyle

Stay hydrated, consume a healthy diet rich in vitamins and antioxidants, and exercise regularly. A nutritious diet and adequate hydration support skin regeneration and help combat skin issues from within.

Regular Skin Checks

Keep your underarm skin checked regularly for any changes, such as new moles, unusual pigmentation, or persistent irritation. In the event that you are experiencing any concerning symptoms, you should consult a dermatologist for a thorough diagnosis and treatment.


Cycling enthusiasm should never be dampened by dark underarm marks. It’s a brilliant way to keep fit and commune with nature, but those bothersome dark patches can be distracting. Don’t worry, though – fighting back is easier than you think. With home remedies as simple as a dab of lemon juice, a sprinkle of baking soda, a dollop of coconut oil, or a slice of cucumber, or if you prefer, medical procedures like laser therapy or chemical peels, you’ll have all you need to banish those marks. So, bid farewell to underarm discoloration and gear up for smoother, more radiant skin to boost your adventure-filled rides.


Natural remedies are generally safe but can irritate some skin types. Test a small area first and discontinue use if irritation occurs.
