Pimples under the armpit are a common skin issue that many individuals encounter. Often overlooked, these blemishes can be not only uncomfortable and painful but can also lead to self-consciousness and distress. The key to effectively managing and treating underarm pimples lies in understanding their causes and implementing effective solutions. This blog post delves into the top 5 treatments that have proven to be effective for tackling pimples in the underarm area.

Understanding Pimples Under the Armpit

Pimples under the armpit, much like pimples elsewhere on the body, are caused by clogged pores. The unique environment of the underarm area, which often experiences a combination of sweat, bacteria, and dead skin cells, creates a perfect breeding ground for these breakouts. Factors such as frequent shaving can also irritate the skin, leading to ingrown hairs and further aggravating the situation. Recognizing these underlying causes is crucial in finding an appropriate treatment approach.

Common Causes of Underarm Pimples:

  • Sweat and Bacteria: The underarm area is prone to sweating, which can mix with natural bacteria on the skin to clog pores.
  • Shaving and Irritation: Shaving can often lead to irritation and cause small wounds that become infected, leading to pimples.
  • Deodorants and Antiperspirants: Certain ingredients in deodorants and antiperspirants can irritate the skin or clog pores.
  • Hormonal Changes: Hormonal fluctuations, often during puberty, menstruation, or pregnancy, can increase the likelihood of pimples.

Tips for Identification:

  • Appearance: Underarm pimples typically appear as small, red, and sometimes painful bumps.
  • Sensitivity: They may be more sensitive due to the thin skin in the underarm area.
Top 5 Treatments for Pimples Under Armpit: What Really Works?

Treatment 1 – Proper Hygiene and Skincare

Good hygiene practices play a pivotal role in treating and preventing underarm pimples. It is important to keep the area clean and dry, but also to do so gently to avoid further irritation.

Key Hygiene Tips:

  • Regular Washing: Use a gentle, fragrance-free soap to clean the underarms daily.
  • Avoid Harsh Scrubbing: While it’s important to keep the area clean, harsh scrubbing can aggravate the skin. Opt for gentle cleansing.
  • Proper Drying: After washing, thoroughly dry the area to prevent moisture buildup.

Skincare Products:

  • Non-comedogenic Moisturizers: After cleaning, apply a light, non-comedogenic moisturizer to keep the skin hydrated without clogging pores.
  • Exfoliation: Gentle exfoliation can help remove dead skin cells, but should be done sparingly to avoid irritation.

Treatment 2 – Over-the-Counter Topical Treatments

For many individuals, over-the-counter (OTC) topical treatments can be a convenient and effective way to manage underarm pimples.

  • Benzoyl Peroxide: Known for its ability to reduce inflammation and kill bacteria, benzoyl peroxide can be very effective. However, it may bleach clothing, so care should be taken when applying.
  • Salicylic Acid: This helps to unclog pores and reduce swelling and redness. It’s a good option for ongoing maintenance.

Application Tips:

  • Follow Instructions: Always use these treatments according to package instructions.
  • Spot Testing: Before applying widely, do a patch test to ensure you don’t have a reaction to the product.
  • Consistency: Regular use, as directed, is key for seeing results.

Potential Side Effects:

  • Skin Dryness and Irritation: These products can be drying, so it’s important to balance their use with proper skin hydration.
  • Sensitivity to Sunlight: Some treatments can make your skin more sensitive to the sun, so it’s advisable to use sun protection.

Treatment 3 – Natural Remedies

In addition to conventional treatments, natural remedies can offer a gentler approach to treating pimples under the armpit. These alternatives are often preferred for their minimal side effects and are easily accessible.

Popular Natural Remedies:

  • Tea Tree Oil: Known for its natural antibacterial and anti-inflammatory properties, tea tree oil can be an effective spot treatment. It should be diluted with a carrier oil, like coconut or jojoba oil, to prevent skin irritation.
  • Aloe Vera: Aloe vera is famous for its soothing and healing properties. Applying aloe vera gel can help reduce inflammation and promote healing.
  • Apple Cider Vinegar: With natural astringent properties, apple cider vinegar can help to balance the pH of the skin and reduce bacteria. Dilute it with water before applying to the skin.

Application and Precautions:

  • Patch Test: Always conduct a patch test to ensure you don’t have an allergic reaction.
  • Gentle Application: Apply these remedies gently to the affected area with a cotton ball or pad.
  • Rinse Off If Necessary: Some natural remedies should be rinsed off after a certain period to prevent skin irritation.

Treatment 4 – Prescription Medications

When OTC treatments and natural remedies are not effective, it may be time to consider prescription medications. Consulting a dermatologist can lead to more targeted and powerful treatments.

Types of Prescription Treatments:

  • Topical Antibiotics: These can help reduce bacteria in the affected area and decrease inflammation.
  • Retinoids: Often used for acne treatment, retinoids can help unclog pores and regenerate skin cells. They must be used under medical supervision due to potential side effects.


  • Consult a Dermatologist: Prescription medications should only be used under the guidance of a healthcare professional.
  • Be Aware of Side Effects: Some prescription medications can have side effects, such as increased skin sensitivity, dryness, or irritation.

Treatment 5 – Lifestyle Changes

Last but not least, lifestyle changes can play a significant role in preventing and treating underarm pimples. Small changes in daily habits can have a big impact on skin health.

Effective Lifestyle Changes:

  • Dietary Adjustments: Incorporate more fruits, vegetables, and water into your diet to promote skin health. Reduce intake of processed and sugary foods.
  • Clothing Choices: Wear loose, breathable fabrics to reduce sweat and friction in the underarm area.
  • Stress Management: High stress levels can exacerbate skin issues. Practices like yoga, meditation, or regular exercise can help manage stress.

Preventive Tips:

  • Regular Showering After Exercising: This helps to remove sweat and bacteria buildup.
  • Avoiding Shared Personal Items: Sharing items like towels can transfer bacteria.

It’s important to remember that individual responses to treatments can vary, so finding the right solution may require some experimentation. With these tips and treatments, you can effectively address underarm pimples and improve your skin health.
